Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing head-mounted displays lack convenience in terms of user comfort and adaptability to different head sizes and shapes, limiting their usability.
Innovation Solution
A head-mounted display design featuring a rotatable first and second housing portion connected by a hinge, adjustable bands, and a flexible electrical connection system, allowing for accommodation and adjustment to fit various head sizes and shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the first housing portion and second housing portion are rigidly connected, then the structural stability is improved, but the adaptability to different head sizes and shapes deteriorates
Solution Approach 1:
The patent applies the dynamics principle by introducing a hinge mechanism that allows the first housing portion and second housing portion to rotate relative to each other. This dynamic connection enables the HMD to adapt to different head sizes and shapes while maintaining structural stability when needed, directly resolving the technical contradiction between rigidity and adaptability.
2Adaptability or versatility
If the second housing portion is made larger to accommodate more components, then the functionality is improved, but the obstruction of the viewing area deteriorates
Solution Approach 1:
The hinge mechanism allows the second housing portion to be dynamically positioned - it can rotate forward to clear the viewing area when needed, while still providing sufficient space for components. This resolves the contradiction between functionality and viewing area obstruction.
3Ease of operation
If the band is made adjustable to fit different heads, then the comfort is improved, but the device complexity increases
Solution Approach 1:
The band incorporates an adjustment mechanism that allows dynamic modification of the head circumference. This enables the HMD to fit different head sizes comfortably while using a relatively simple mechanical adjustment system, balancing comfort improvement with acceptable device complexity.
