HMD Mounting Plate With Resilient Locking Against Slip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mounting systems for head-mounted displays (HMDs) fail to securely attach electronics to the user's head for extended periods due to material relaxation, leading to failure.
Innovation Solution
A mounting system featuring an electronic component housing with a sliding connection to an adapter plate, utilizing resilient tabular members and channels to resist sliding displacement, allowing adjustable and secure attachment to the user's head.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional interference fit mounting devices are used, then initial secure attachment is achieved, but material relaxation occurs over time resulting in mounting failure
Solution Approach 1:
The mounting system transitions from a static interference fit to a dynamic adjustable connection. The adapter plate with channels and resilient tabular members allows the electronic component housing to be slidingly connected and adjusted to different positions, then securely locked. This dynamic system maintains mounting security over extended periods by allowing initial adjustment and subsequent stable locking, preventing the material relaxation failure that plagues static interference fit designs.
2Ease of manufacture
If fixed mounting positions are used, then manufacturing simplicity is maintained, but adaptability to different user needs is reduced
Solution Approach 1:
The mounting system segments the connection interface into discrete adjustable elements. The adapter plate features channels with multiple engagement positions and resilient tabular members that can lock at different locations. This segmentation allows the electronic component housing to be positioned at multiple discrete locations along the channels, providing adaptability for different user needs while maintaining a relatively simple manufacturing process compared to fully continuous adjustment mechanisms.
3Adaptability or versatility
If adjustable sliding connection is implemented, then position adaptability is improved, but device complexity increases
Solution Approach 1:
The resilient tabular members are designed to automatically engage with the channels and lock the electronic component housing at selected positions without requiring additional fastening operations. The resilient nature of these members allows them to flex during adjustment and then self-lock when engaged, providing adaptability while minimizing the complexity of the mounting system by eliminating the need for separate locking mechanisms or tools.
