The present invention relates to the bedding industry and more specifically to a system and method for recommending a bedding product.
As bedding products become more advanced, customers have more component options from which to choose. For example, one can customize various components and features of a mattress and box springs. Certain component types and features, which provide various levels of support and cushion, are more appropriate for some types of customers than others. Component suitability depends on a variety of factors, such as body type, weight, flexibility, weight distribution, etc. As appropriate components can contribute to more restful sleep and proper support of various portions of a user's body, selecting components is an important determination. Unfortunately, it is often difficult for a customer to know which component attributes, such as level of firmness, will be most suitable for the customer. Various attempts have been made to assist customers with bedding product decision-making processes.
For example, U.S. Pat. No. 6,571,192 discloses an air mattress with sensors, which measures an individual's weight distribution and matches the individual to a suitable mattress system. However, among other things, the '192 patent fails to measure pressure changes at various portions of the mattress system and, therefore discloses a solution limited in the feedback that it can provide to an individual with respect to multiple mattress system components.
In addition, U.S. Pat. No. 5,148,706 discloses a mattress with sensors connected to springs of the mattress, which measure the pressure an individual exerts on the springs.
Additional limitations of the art include the failure to assess a customer's body flexibility.
There is now provided a new method and system for recommending a bedding product.
One objective of the present invention is assessing a customer's needs based on feedback provided at various portions of a bedding system. An additional objective of the present invention is assessing both weight distribution and body flexibility of a customer.
Systems and methods for recommending a mattress customized for a particular individual are provided. By having an individual position themselves upon a test mattress system, and measuring pressures at various locations within the test mattress system while one or more air bladders are filled to various relative air pressure values, the system determines how a mattress could be constructed to properly support the individual at various regions across the mattress. In embodiments, the systems and methods utilize a pressure profile for a particular individual to compare to a set of reference profiles in selecting a bedding product to recommend to the individual.
In one embodiment, the present invention comprises a method for recommending a bedding product for an individual. The method includes the steps of taking a first pressure measurement of at least one bladder situated within a test mattress system while the individual reclines on the test mattress system. The method then elevates pressure within the bladder and takes a second pressure measurement of the bladder while the individual reclines on the test mattress system. The first pressure measurement represents weight distribution of the individual, while the second pressure measurement represents the body flexibility of the individual.
In another embodiment, the present invention comprises a test mattress system for recommending a bedding product for an individual. The system includes a mattress portion having a support structure and a box spring portion situated beneath the mattress portion. A middle zone is located between the support structure and the box spring portion and has at least one fluid bladder located therein.
The present invention is described in detail below with reference to the attached drawing figures, wherein:
Referring now to
One advantage of the present invention is the degree to which it simulates an actual mattress system, such as one a consumer would ultimately purchase for personal use. Accordingly, when the test mattress system 100 of the present invention takes measurements and provides feedback, the feedback is consistent with what a consumer would find in an actual mattress system.
For example, the mattress portion 102 is constructed with a support structure 106, and the box spring portion 104 is generally positioned beneath the mattress portion 102. The support structure 106 may comprise any component known by those of ordinary skill in the art to be used as such, and in one embodiment, the support structure 106 is a series of upright spring coils. Alternatively, the support structure may comprise a fluid medium, such as air, in one or more bladders or a combination of spring coils and fluid medium filled bladders. In addition, the mattress portion 102 may be constructed with a top cushioning material 108, positioned on top of the support structure 106. Accordingly, one or more zones exist within the system 100. One such zone is a middle zone located between the support structure 106 of the mattress portion 102 and the box spring portion 104. Other zones include an area directly above and overlaying the support structure, an area within the top cushioning material 108, an area directly below the support structure, and an area directly above and overlaying the box spring portion.
Fluid bladders 110, 112, 114, 116 of the present invention are designed to measure pressure and changes in pressure within the test mattress system, such as when an individual reclines on the system. In one embodiment, the fluid bladders 110, 112, 114, 116 are filled with air. Preferably, sensors 118 are coupled to the fluid bladders 110, 112, 114, 116, and the sensors 118 are configured to measure pressure within the fluid bladders 110, 112, 114, 116. One or more fluid bladders located within a zone are designed to measure pressure changes within that zone. For example, fluid bladders may be positioned within the top cushioning layer 108, on top of the support structure 106, underneath the support structure 106, on top of the box spring portion 104, or any combination thereof. A fluid bladder 110 positioned within the top cushioning layer 108 is designed to measure pressure changes within the top cushion layer 108. In embodiments of the present invention, the test mattress system comprises a layer of one or more primary fluid bladders 110 within the top cushioning layer 108, a layer of one or more top support structure fluid bladders 112 on top of the support structure 106, a layer of one or more bottom support structure fluid bladders 114 underneath the support structure 106, and a layer of one or more top box spring fluid bladders 116 on top of the box spring portion 104. Embodiments of the present invention comprise a layer of one or more fluid bladders positioned within at least one or more of the aforesaid listed positions, i.e. within the top cushioning layer 108, on top of the support structure 106, underneath the support structure 106, or on top of the box spring portion 104. Fluid bladders may be positioned within any combination of the aforesaid listed positions. Fluid bladders may also be positioned within all of the aforesaid listed positions.
In embodiments of the present invention, laterally-spaced, parallel, interconnected channels (not shown) may be constructed to connect bladders within a same layer. Said channels provide evenly distributed support across the layer by evenly distributing fluid within the bladders. Furthermore, each fluid bladder layer may be connected by channels (not shown) to one or more other fluid bladder layers to provide pressure equalization across all fluid bladder layers of the system. In a further arrangement, the system of the present invention comprises a device for increasing and decreasing the pressure of the one or more fluid bladders 110, 112, 114, 116.
An array of sensors 118 are coupled to each layer of one or more fluid bladders 110, 112, 114, 116. In one arrangement, sensors 118 are distributed throughout each layer of one or more fluid bladders 110, 112, 114, 116 in a horizontal x-y grid. The sensors 118 function to measure pressure changes within the one or more fluid bladder layers 110, 112, 114, 116. For example, changes in pressure may occur when an individual reclines on the mattress. Changes in pressure may also occur when fluid is either put into, or released from, fluid bladders. Further, sensors 118 function to measure pressure changes at positions of the system, the positions corresponding to where various parts of the individual's body would be resting, the parts including, but not limited to, head, neck, shoulders, mid-section, waist, hips, and feet.
Preferably, output from sensors 118 are coupled to a processor (e.g., a microprocessor and memory, or an application-specific integrated circuit) for computing pressure values based on the sensor output. The processor is also coupled to a storage device (e.g., a computer hard drive, or other removable or non-removable storage means) for storing the pressure values of each sensor, and is further connected with a database of reference values that correlate with a particular reference cushioning profile.
A reference cushioning profile functions as a guide against which pressure values resulting from a reclining individual may be compared to determine a proper bedding product for the individual. Reference cushioning profiles may be developed by recording relevant characteristics of a test group of individuals for storage in a database. Relevant characteristics of a test individual include, but are not limited to, body type (e.g. height, weight, waist size, shoulder size, etc.); pressure exerted by the test individual on the system's one or more fluid bladder layers 110, 112, 114, 116 when the fluid bladder layers are filled to a first pressure; pressure exerted by the test individual on the system's one or more fluid bladder layers 110, 112, 114, 116 when the fluid bladder layers are filled to a second pressure, the second pressure elevated relative to the first pressure; and a proper bedding product for the test individual based on the individual's weight distribution and flexibility. Pressure values for each individual in a test group may be obtained at varying bladder air pressure values in order to measure both weight distribution and body flexibility for the individuals, ensuring that the reference cushioning profiles developed are reflective of support distribution across the mattress.
Methods of the present invention comprise steps for recommending a bedding product to an individual and utilize a test mattress system 100 of the present invention. Accordingly, any embodiment of the test mattress system disclosed, expressly or inherently, herein may be used in the methods of the present invention. In one embodiment, a method comprises the steps of taking a first pressure measurement of at least one bladder situated within the test mattress system 100 while the individual reclines on the test mattress system 100; elevating pressure within the at least one bladder; and taking a second pressure measurement of the at least one bladder while the individual reclines on the test mattress system 100.
