BACKGROUND OF THE INVENTION

This section is intended to introduce various aspects of the art, which may be associated with exemplary embodiments of the present disclosure. This discussion is believed to assist in providing a framework to facilitate a better understanding of particular aspects of the present disclosure. Accordingly, it should be understood that this section should be read in this light, and not necessarily as admissions of prior art.

Field of the Invention

The present inventive concept relates to the field of head support systems. More particularly, the concept relates to an improved head support system for keeping a user's head upright while using hair dryer chair or using any medical device for which head support can be appropriate.

Technology in the Field of the Invention

Salon services can range from a simple haircut, completed in about 20 minutes, to a full hair color change, shampoo, blow dry, and a cut, which can last for several hours in a single salon visit. An especially lengthy stage in this process includes the time required for hair to dry or to absorb dyes while positioned under a hair dryer. This process is particularly tedious for the client, who must remain in an upright, seated position for extended periods of time, all while ensuring that his or head is centered within the bowl of the dryer for optimum results. If the client fails to maintain the correct posture and location, their hair dries unevenly, which can potentially ruin the client's hairstyle or color. In certain circumstances, the only remedy for these adverse effects is to repeat the entire process, wasting valuable time for the salon, salon personnel, and the client.

DETAILED DESCRIPTION OF CERTAIN EMBODIMENTS

Detailed descriptions of one or more preferred embodiments are provided herein. It is to be understood, however, that the present invention may be embodied in various forms. Therefore, specific details disclosed herein are not to be interpreted as limiting, but rather as a basis for the claims and as a representative basis for teaching one skilled in the art to employ the present invention in any appropriate manner.

Definitions

The singular forms “a,” “an,” and “the” include plural reference unless the context clearly dictates otherwise. The use of the word “a” or “an” when used in conjunction with the term “comprising” in the claims and/or the specification may mean “one,” but it is also consistent with the meaning of “one or more,” “at least one,” and “one or more than one.”

Wherever any of the phrases “for example,” “such as,” “including” and the like are used herein, the phrase “and without limitation” is understood to follow unless explicitly stated otherwise. Similarly “an example,” “exemplary” and the like are understood to be non-limiting.

The term “substantially” allows for deviations from the descriptor that do not negatively impact the intended purpose. Descriptive terms are understood to be modified by the term “substantially” even if the word “substantially” is not explicitly recited. Therefore, for example, the phrase “wherein the lever extends vertically” means “wherein the lever extends substantially vertically” so long as a precise vertical arrangement is not necessary for the lever to perform its function.

The terms “comprising” and “including” and “having” and “involving” (and similarly “comprises,” “includes,” “has,” and “involves”) and the like are used interchangeably and have the same meaning. Specifically, each of the terms is defined consistent with the common United States patent law definition of “comprising” and is therefore interpreted to be an open term meaning “at least the following,” and is also interpreted not to exclude additional features, limitations, aspects, etc. Thus, for example, “a process involving steps a, b, and c” means that the process includes at least steps a, b and c. Wherever the terms “a” or “an” are used, “one or more” is understood, unless such interpretation is nonsensical in context.

As used herein the term “about” is used to mean approximately, roughly, around, or in the region of. When the term “about” is used in conjunction with a numerical range, it modifies that range by extending the boundaries above and below the numerical values set forth. In general, the term “about” is used herein to modify a numerical value above and below the stated value by a variance of 20 percent up or down (higher or lower).

For purposes of the present disclosure, it is noted that spatially relative terms, such as “up,” “down,” “right,” “left,” “beneath,” “below,” “lower,” “above,” “upper” and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over or rotated, elements described as “below” or “beneath” other elements or features would then be oriented “above” the other elements or features. Thus, the exemplary term “below” can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

The words “user,” “client,” and “customer” can be used interchangeably to refer to any individual receiving salon services or hair-care services.

I. Introduction/Background

Making people feel good about the way they look through salon services is key for running a beauty salon business. One key aspect of satisfying people at the salon is the comfortable experience one receives. Frequently, after a customer gets a hair service done, washing and drying the customer's hair is required. At times, customers could spend up to an hour under a hooded hair dryer. Many individuals are known for falling asleep at this time or getting uncomfortable quickly due to the user having to hold their head upright for an extended period of time. The presently disclosed neck support is configured for hooded hair dryers and will allow users to comfortably relax while their hair dries. Current hooded hair dryers do not provide support for the user's neck which results in hair not drying properly and leading to neck discomfort.

The top hair salon franchises, such as Supercuts®, use Belvedere Professional Salon Dryers, so the team was directed to build a prototype that would fit the constraints of professional stationary salon dryers. The working prototype is achieved through extensive research of the dryers, ergonomics, and the client's given standards. The professional stationary salon dryers consist of three main components: the drying duct, the housing of the dryer, and the bowl. The prototype is designed to not interfere with the components of the dryer as well as the dryer's purpose.

The benefits of the neck support, called the Heads Up Device, are that salon customers will enjoy their hair salon experience more with some much-needed added comfort. Also, the salon stylist will save time by not having to go back over the hair. Currently, the hair salon market does not have anything like this device. The hair salon market is a very lucrative industry with the global market estimated around 87.7 billion dollars in 2018 (Trefis.com, 2017). Specifically, Sally Beauty Holdings Inc. sells and distributes to over 5,000 stores, including 175 franchised units, which is where this device could possibly be retailed through (Sally, 2017). Just in the U.S. alone, beauty, cosmetics, and fragrance stores revenue around 22.2 billion dollars last year (Cohen, 2018). Undoubtedly, the hair salon market has huge opportunities for new products, in which the client hopes the Heads Up Device could thrive in.

II. Project Methodology

A salon visit can be a very complex and extensive process for some customers. Salon services can range from a just a simple haircut, completed in 20 minutes, all the way to a full hair color change, shampoo, blow dry, and a cut, lasting hours in one salon visit. One of the longer salon processes is allowing for the hair to dry or soak up hair dyes while under a hair dryer. The tedious part of this process is that the user must remain in an upright seated position while centered under the bowl of the dryer for up to an hour. If the user does not remain in the correct position, the hair dries unevenly causing adverse effects on the hairstyle and results in having to repeat the process. The intended final product function is to comfortably support the user's head and neck in the upright seated position while under a stationary salon dryer.

In order to be marketable to salon owners, the team wanted the design to be portable, easy to assemble, adjustable, and look sleek and professional. To be portable and easy to transfer from dryer to dryer, the maximum weight was constrained to 15 pounds. To reduce packaging and shipping costs of the final product, we assumed the design would need to be in as few parts as possible so that the salon workers could assemble it themselves. For ease of assembly, the product should be packaged as a maximum of two parts with one step for assembly. The design had to be adjustable to reach heights of 5th percentile females and 95th percentile males according to ergonomic standards. To meet these standards, the neck rest should extend between 7-18 inches from the base of the dryer. We wanted our design to look sleek and professional by looking uniform with the dryer, that is, all parts colored black with a smooth or glossy finish.

The main functional requirement of the Heads Up device is that it must support a 12-pound head plus the additional weight of curlers, foils, and products in the user's hair. The device should also support additional body weight as a safety precaution in the incident that someone uses the device incorrectly. The goal of our design was to fit all professional stationary salon dryers. Major constraints faced were that all materials must be resistant to deformation at temperatures up to 160 degrees Fahrenheit which is the maximum heat of the dryer. All materials used also had to be resistant to chemicals used in hair salons, specifically, hydrogen peroxide, ammonia, and aniline derivative. The air duct that extends out of the base of the dryer and holds the dryer bowl up is held up only by friction, so our design could not place any downward force on the air duct or dryer bowl. Finally, the Heads Up product cannot block any air blowing out of the dryer bowl or interfere with the user's hair style.

Customers often have trouble keeping their head in the correct position while getting their hair dried under a hooded salon hair dryer. This causes un-evenly dried hair and may result in an undesired result in their appearance. We designed a comfortable headrest that aids in keeping the user's head in a stationary position. The design, went through many iterations, but a final prototype was completed and approved.

There are several brands of salon hooded hair dryers on the market, such as Belvedere, Gemini, and Venus. Each brand was assessed for their constraints to attempt to design a headrest that would fit each model. The drying duct of each model is held in by friction alone, so no weight could be placed directly on the dryer duct without the risk of it moving. There is 0.5 inches of dryer base in front of the dryer duct and less than 1 inch of dryer base on either side of the dryer duct. The device could also not interfere with the user's hairstyle. Given these constraints, existing headrests and patents were researched, but no product currently exists on the market.

The headrest must be able to fulfill several functional requirements as well. The design needed to withstand temperatures up to 160° F. from the dryer bowl and be resistant to common chemicals found in a hair salon. The device needed to support 12 pounds, the average weight of a human head. Ergonomics of headrests were researched, and the adjustability should meet 5th percentile of women and 95th percentile of men, thus the headrest height range should be between 7-18 inches from the base of the dryer to accommodate for both. The minimum width of a headrest should be 7.784 inches to prevent the head from sliding. The area where the headrest comes in contact with the neck should be highly energy-absorbent and have a vertical contour adapted to the normal sitting posture. The surface should be padded with a soft upholstery to prevent irritation.

We brainstormed three ideas based on the constraints and functional requirements. A prioritization matrix composed of several weighted criterion was used to choose the best design. Support and comfort were the most important qualities of the design. Cost was the next most important because the client wanted the retail price to be under $80. Once the design was selected, the next step was to research materials that would be best for a prototype.

After thorough research, ABS plastic was chosen for the prototype. ABS plastic met the minimum requirements for heat and chemical resistance, and it is strong enough to support the weight of an average human head. ABS plastic was also picked because it would allow the design to be printed at UA's 3D printing lab. Silicone was chosen for the headrest because of its high energy-absorbent properties and its resistance to chemicals. Silicone's high heat resistance and it's easy to clean surface deemed Silicone as an appropriate material selection for the cushion.

Once the design and bill-of-materials were approved, the design was printed, and a silicon cushion was ordered that would easily fit over the cushion support. The first prototype can be seen in FIG. 17. The prototype had two attachable legs on the back to prevent the design from sliding forward on housing of the dryer. The hole seen on the side of the design base was for a removable pin to prevent forward moments that would cause it to rotate. The connector on the prototype was adjustable via a spring pin. The spring pin would allow the connector to extend in three positions.

After the prototype finished printing, the device was taken to an in-home salon and tested. As expected though, the prototype had no issues with the heat produced by the dryer. The maximum heat of the dryer did not exceed the thermal range of ABS plastic or the Silicone cushion, implying the materials were well chosen.

We brainstormed new ideas and revised the prototype. The base of the design was kept similar, but the legs were removed and replaced with nylon straps. Due to limited clearance on the housing of the dryer, a stackable base was developed with five slots on one base. These slots allowed the neck to detach and reach a bigger height adjustability range without interfering with the dryer duct or the seat. A second base could be stacked on the first base to accommodate for the sitting height of 95 percentile men. The new design for the base can be seen in FIG. 4.

Following the revision of the design base, the connector needed a method of sliding into the slots easily. A tab was integrated into the bottom of the connector. The tab comes out at a 45° to allow it to be inserted and removed to not interfere with the dryer duct. An FEA was analyzed on the tab to confirm it could support the necessary weight. The connector shape was revised as well. It was given an “S” shape to come out a distance from the dryer and then rise up for additional height, and finally back out where it connects to the cushion support. This “S” shape also creates space giving the connector clearance, so it does not interfere with the bowl of the dryer. The connector piece can be seen in FIG. 3. When inserted into the slots of the base, the connector had adjustable heights of 6.25″, 7.35″, 8.45″, 9.55″, and 10.65″. When the second base is stacked on the first base, the connector reached additional heights of 11.75″, 12.85″, 13.95″, 15.05″, and 16.15″.

Originally, the cushion support angle was going to be adjustable, but due to input from professionals in the salon industry, the cushion support has a fixed position. This was done so at the point of contact with the neck, it would not interfere with hair accessories. The cushion support's radius was also increased to accommodate as many neck sizes as possible. This increase in radius required a new cushion support to be ordered. The material remained the same because Silicone performed well in thermal testing. The new cushion support did have extra padding for increased comfort. The second prototype can be seen in FIG. 1.

Once the prototype was finished printing, it was tested at the local JCPenney salon. The design fit well on the dryers at JCPenney, but the dryers were not designed for the 95th percentile of men, therefore the second stackable base was causing interference with the dryer bowl. We then cut the second base, so it would fit properly on the dryer duct with no interference. The second stackable base has only two height adjustment options. The stackable base can be seen in FIG. 5.

Preliminary testing data was collected using Finite Element Analysis (FEA) on the connector component of the Heads Up device. The tab on the connector was determined to be the weakest feature in the design, as failure at this point would be catastrophic. In FIG. 20, to mimic a worst-case scenario, a 12-pound force was placed on the top end of the connector component, shown by the purple arrows, and the tab was constrained as if it was inserted in the base component of the device.

With the above scenario the maximum deflection was 0.04161 inches and the prominent stresses were displayed at the point where the tab contacts the base. The von-Mises stresses reached a maximum of 682.5 psi in the corners, mainly due to stress concentrations, shown in FIG. 21. The data gathered from the FEA validated the premises of the device and allowed the team to move on to in field testing with the prototype.

In field testing of the prototype was broken down into five main categories: a heat test, a fit and function test, a height validation test, a strength test, and a user feedback test. The heat test was designed to test different points on the device and validate the temperatures seen by the device do not exceed the material selected heat resistance temperatures. During the heat test, the device was assembled on the dryer with the maximum heat setting turned on. A Fluke infrared thermometer scanner is to be used to take the various temperature measurements. The temperature measurements consisted of points on the base, the connector, the cushion, and the buckles. The areas where the temperatures were taken were chosen due to their proximity to the dryer duct or hood. The temperature for the cushion and connector were taken in the areas where the components were exposed to direct heat from under the dryer bowl. The base and buckles contact the dryer duct and receive the greatest amount of heat. After 30 minutes from start up, professional hooded hair dryers reach their maximum temperature, so the team decided to conclude the heat test then,

The fit and function test included various aspects of the device fitting on the dryer. The device was assembled on the dryer and checked for stability, clearance, and appropriate neck client neck alignment. To ensure the connector did not interfere with the normal operation of the dryer, the bowl was lowered into position as if the dryer was in use. The neck height was be checked by user validation. Next, the height requirement test was used to validate if the device satisfies the ergonomics standards of the sitting neck height for 5th percentile women and 95th percentile men. The device was checked for a range between 22 to 29 inches with the use of a standard measuring tape. A strength test was performed as well to further validate the FEA analysis. The device was mounted by straps and weight was added to the connector component until failure. The strength test was performed to provide further insight on how durable the design was.

Testing concluded with putting the device in use with actual salon customers and professional stylists. Two surveys were developed to allow the team to receive honest feedback on the device. The first survey was given to salon customers, and the second survey was given to the professional salon stylists. The device was rated on a scale from 1 to 5, with 1 being strongly disagree and 5 being strongly agree.

After the prototype was 3-D printed, the team conducted a series of tests outlined previously in this report at a local professional hair salon. First, the device was assembled on a Belvedere stationary hooded hair dryer and the fit and function of the device was assessed. The base of the device fit securely and evenly on the dryer with the straps attached. The device did not tip or appear unstable. Regarding the angle of the connector component, the bowl of the dryer did not have interference with the device, shown in FIG. 11.

The device was then checked to see if there was any interference with the user and if the device could reach the user at the appropriate neck position. FIG. 12 shows the device in use and contacting the upper part of the user's neck, as desired.

Next, the team conducted the heat test to validate the material selection. The device was assembled on the Belvedere dryer and the dryer's heat was turned on the maximum heat setting. As noted earlier, heat measurements were taken at various points on the device to ensure no critical temperatures were present.

At 5 minutes, the first set of temperature measurements were taken with an Infrared Temperature Scanner. Then, measurements were taken at 5-minute increments up until the 30-minute mark was reached. Table 1 below shows the results of the heat test.

The results from Table 1 displays the highest temperature at 110.5 degrees Fahrenheit found at the cushion, which is directly under the heat source. However, the cushion material is Silicone and it is heat resistant up to 400 degrees Fahrenheit. ABS Plastic is heat resistant up to 264 degrees Fahrenheit, so the other temperatures are well below the critical limit for the device's material selection.

Following the heat test, the height validation test was conducted. With the device on the dryer, measurements were taken from the bottom of the chair to the center of the cushion, which measures the sitting height up to the neck. It was discovered that the dryer itself could not reach the 95th percentile men sitting height, yet the 5th percentile women sitting height was achieved. The height measurements are shown in Table 2 below, which validated the height requirement of the device.

The last slot on the half base reaches the full range of the 5th percentile women. Originally, two full bases were printed, yet the dryer's neck would not extend upward enough for the 2nd full base slots to ever be utilized, so a half base was printed instead.

After the height validation test, the device was tested with actual salon users and professional salon stylists. The device was rated on comfort, adjustability, appearance, effectiveness, heat effects, and ease of use for the salon user survey. With 10 participants, the device received overall positive feedback, shown in FIG. 18.

From FIG. 18A, the device rated well on all the categories. A few of the salon customers did not answer on the ease of use category due to the stylist adjusting the device for them. The salon stylists rated the device on a few different categories such as client interference, maintainability, and assembly. With 4 participants, the stylists rated the device and the results were pleasing. FIG. 18B depicts the results.

Lastly, to further validate the robust of the design, the strength test was done targeting the tab on the connector component. A spare half base and a spare connector part was assembled and constrained by straps, shown in FIG. 19A.

In FIG. 19A, the device is shown with weights that applied a downward force of 45 pounds on the top of the connector component. FIG. 19B displays the resulting reaction of the weight.

Once the weight limit reached 45 pounds, the base slot cracked and tore apart, instead of the anticipated weak point, the tab. Although the strength test displayed the base failing before the tab, the team still anticipates the tab to be the weakest point. Due to the prototype being 3-D printed, the device reacted differently to the weight. With injection molding, the device's strength will be enhanced as it is made as a whole and not made layer by layer, which is the method used in 3-D printing.

In an alternate embodiment, the neck rest fully integrated into a professional stationary salon dryer. Essentially, the product would replace the dryer's drying duct with an aftermarket one that has a neck rest built in. This type of product would eliminate the constraint issues for the neck rest and improve the build quality of the dryer itself.
