The present application claims the benefit of Chinese Patent Application No. 201810748446.0 filed on Jun. 29, 2018. The contents of the above are hereby incorporated by reference.
The present invention relates generally to fashion design, and more particularly, to a system for designing brassiere based on virtual reality technology.
Statistics showed that 80% of women of developed countries in Europe and America wore incorrectly sized brassiere. Similarly, this phenomenon also applied in developing countries, so made-to-measure brassiere may solve this problem.
Women always expect to wear correctly sized and charming brassiere designed by themselves on any occasion. However, it is difficult for a woman to communicate her ideas and thoughts with the designer. In the mean time, women are usually not familiar with how to design a brassiere.
But now, basing on virtual reality technology, it is possible to design an expected personalized brassiere by experiencing immersion into a simulation environment of three dimensional dynamic vision with physical interaction with objects, in which the user can select wearing scene and match clothing by applying a brassiere design application program and using a smart mobile terminal.
However, as a bra cup is vital to fitness of a brassiere, physical objects are still required for simulating wearing effect of the brassiere, so as to guide the design of the brassiere.
Described herein is a virtual reality system for designing brassiere, which makes it possible for a user to experience the effects of tightened or loosened brassiere, uplifting, compression, enlargement of the breast, and breast massage in a virtual reality environment with physical interaction with objects in real world. Afterwards, relevant data will be transferred to a cloud server via a built-in transducer, and an expected brassiere will be designed.
To achieve the goals, the virtual reality system for designing brassiere comprises a wearable device, a head-mounted device, a cloud server, an intelligent terminal, an application program and a designer.
The wearable device is a bra-like wearable device comprising bra cups, top bindings, bottom bindings, side wings, shoulder straps, back wings and independently controllable air charging-discharging mechanisms.
The bra cup comprises a main body, an external air bag arranged on an external surface of the main body, and an array of internal air bags arranged on an internal surface of the main body. The bra cup has different sizes and models.
The main body is made of silicone rubber. Hardness of the silicone rubber ranges from 50 to 70. Thickness of the main body ranges from 0.5 mm to 2 mm.
The external air bag is arranged on the external surface of the main body. A wall of the external bag is made of polyurethane rubber. Thickness of the wall of the external air bag ranges from 0.05 mm to 0.1 mm. The external air bag is connected to the independently controllable air charging-discharging mechanism. A displacement sensor and a space positioning sensor are internally arranged on a front side of the wall of the external air bag. The displacement sensor and the space positioning sensor are configured to simulate the effects of breast enlargement and breast asymmetry correction. A pressure sensor, a heart rate sensor and a respiration sensor are internally arranged on a back side of the wall of the external air bag. The pressure sensor, the heart rate sensor and the respiration sensor are configured to monitor the wearable device's influence on cardiopulmonary function of the user.
The array of internal air bags is arranged on the internal surface of the main body. Diameter of the internal air bag ranges from 5 mm to 20 mm. A wall of the internal air bag is made of polyurethane rubber. Thickness of the wall of the internal air bag ranges from 0.02 mm to 0.05 mm. The internal air bag is connected to the independently controllable air charging-discharging mechanism. A pressure sensor, a displacement sensor and a space positioning sensor are internally arranged on a back side of the wall of the internal air bag. The pressure sensor, the displacement sensor and the space positioning sensor are configured to simulate the effects of tightened or loosened brassiere, uplifting, compression, enlargement of the breast, and breast massage.
The top bindings, bottom bindings, side wings, shoulder straps and back wings are made of elastic fabric and are internally arranged with pressure sensors configured to record data related to the force applied on corresponding parts of the user's body. By combining the data and lengths of the top bindings, bottom bindings, side wings, shoulder straps and back wings, it is possible to calculate suitable sizes of the top bindings, bottom bindings, side wings, shoulder straps and back wings for the user through specific algorithm.
The independently controllable air charging-discharging mechanism comprises a power supply, a control circuit, an air pump and an air channel. The control circuit receives instruction from the user via a wireless communication module, and controls the air pump, so as to charge or discharge the external air bag and the internal air bags.
The head-mounted device comprises a smart display helmet, a pair of smart glasses and accessories.
The smart terminal may be a smart phone, a smart tablet, a computer, a smart household appliance, a smart car, a smart mirror or a piece of intelligent furniture.
The cloud server is configured to provide stored data, process data collected by the wearable device and the head-mounted device, match scene, transfer data, encrypt data and produce a brassiere design plan for the user.
The application program comprises a virtual reality application program and a smart terminal application program. The virtual reality application program is configured to establish and update database of space scenes and wearing scenes. The space scenes may be bedroom, living room, ballroom, office, workshop, grassland, beach or transport scene. The wearing scenes may be swimwear, underwear, night skirt, dress, skirt, business suit or cheongsam. The smart terminal application program is configured to collect 3D human body data of the user and communicate with a designer and a manufacturer. The 3D human body data comprises height, weight, age, somatotype, BWH (bust, waist, hip) measurements and breast type.
The designer may be a human designer or an artificial intelligence designer, who assists the user with the brassiere design, e.g. brassiere structure optimizing, selection of material, color, pattern and accessories.
Further, an electrode chip is internally arranged on the back side of the wall of the internal air bag. The electrode chip comprises a power supply, a circuit, an electrode and a control chip. The electrode chip touches skin of the user's breast and simulates the effects of water permeation, air permeation, sweating, and high or low body temperature.
Further, the wearable device connects with the head-mounted device via the wireless communication module, so as to realize user-machine interaction. The user-machine interaction may be achieved by voice, gesture, eye tracking or brain-machine interface.
Further, the displacement sensor and the space positioning sensor internally arranged on the front side of the wall of the external air bag output data and receive data related to characters of an external half of the bra cup, while the pressure sensors, the displacement sensors and the space positioning sensors internally arranged on the back sides of the walls of the internal air bags output data and receive data related to characters of an internal half of the bra cup. The data related to characters of the external half and the internal half of the bra cup enables establishment of a 3D model of the bra cup, e.g. relatively thin bra cup, moderately thick bra cup, bra cup with relatively thin upper part and relatively thick lower part, bra cup with relatively thin upper part, relatively thick lower part and relatively thick side edge.
Further, the virtual reality application program comprises the step of inviting the designer or friends to enter the virtual reality environment and assist with the brassiere design, wherein the designer or friends wear the head-mounted device or use the mobile smart terminal to realize user-machine interaction by means of wireless communication connection and assist with the brassiere design.
Further, the virtual reality application program comprises an intelligent recommendation module and a demand-based fuzzy recommendation module. Through specific algorithm, the intelligent recommendation module recommends one or more brassiere design plans for the user based on data, e.g. the 3D human body data provided by the user, the user's previous brassiere design data, data related to the user's online purchased brassiere, selected space scene and selected wearing scene. The demand-based fuzzy recommendation module recommends one or more brassiere design plans for the user based on the user's demand. The user can express her demand by voice, gesture, eye tracking, text entry, image entry or image recognition. The demand may relate to style, factor, meaning and conception of the brassiere design.
Further, the smart terminal application program comprises the step that the user shares the brassiere design, requests for advice from friends, participates in a brassiere design competition and releases bidding information, and steps of finishing the entrusted brassiere design project and manufacturing the brassiere.
Further, the procedure of designing an expected brassiere comprises the following steps.
S1: downloading the application program via the smart terminal and signing a registration agreement;
S2: uploading fundamental body parameters and sending demand for brassiere design;
