Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Women face challenges in communicating their bra design preferences effectively to designers due to sizing issues and a lack of familiarity with the design process, with 80% of women wearing incorrectly sized bras, and existing virtual reality solutions lack physical interaction for accurate simulation.
Innovation Solution
A virtual reality system comprising a wearable bra-like device with controllable air mechanisms, sensors, and a cloud server that allows users to experience and design personalized bras through physical interaction, simulating effects like breast enlargement and massage, and transferring data for custom design creation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If physical objects are used for simulating wearing effect, then simulation accuracy is improved, but device complexity increases
Solution Approach 1:
The patent implements nesting by placing multiple internal air bags inside the bra cup structure, with each air bag containing sensors and controllable elements. This nested configuration allows the system to simulate various breast shapes and sizes while maintaining a compact wearable device structure, resolving the contradiction between simulation accuracy and device complexity
Solution Approach 2:
The patent uses controllable air bags filled with gas to simulate different breast shapes, sizes, and firmness levels. By adjusting the air pressure in these bags, the system can accurately represent various wearing effects without requiring complex mechanical structures, thus improving simulation accuracy while controlling device complexity
2Ease of operation
If virtual reality environment is used for design, then user experience is improved, but physical interaction capability deteriorates
Solution Approach 1:
The patent uses a head-mounted display as an intermediary that overlays virtual information onto the physical world. This allows users to experience virtual reality effects while maintaining physical interaction with the wearable device and their actual bodies, resolving the contradiction between enhanced user experience and preserved physical interaction capability
Solution Approach 2:
The patent merges virtual reality simulation with physical wearable device functionality. The system combines virtual visual feedback from the head-mounted display with physical sensations from the wearable bra, creating an integrated experience that enhances user interaction while maintaining reliability of physical effects

AI summary
A virtual reality system for designing brassiere includes a wearable device, a head-mounted device, a cloud server, an intelligent terminal, an application program, and a designer, 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 the cloud server via a built-in transducer, and an expected brassiere will be designed accordingly.
