Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the head mounted display device uses a fixed bracket structure, then the device structure is simple, but it cannot accommodate users with different head sizes leading to discomfort or damage
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed bracket structure into an adjustable one. The bracket includes a sliding part that can move along the host, allowing the distance between the bracket and host to be changed. This dynamic adjustment capability enables the device to adapt to different head sizes while maintaining a relatively simple overall structure.
Solution Approach 2:
The patent implements parameter changes by allowing the position parameter of the bracket to be adjusted. The sliding part can change its position along the host, thereby changing the distance parameter between the bracket and host. This parameter adjustment mechanism enables adaptation to different users without significantly increasing structural complexity.
2Ease of operation
If the bracket is made adjustable to fit different head sizes, then wearing comfort is improved, but the device structure becomes more complex
Solution Approach 1:
The adjustable bracket structure uses a sliding mechanism that allows easy adjustment of the bracket position. The sliding part can move along the host and be locked at different positions, providing wearing comfort for different head sizes while keeping the adjustment mechanism simple and intuitive.
Solution Approach 2:
The device incorporates a locking mechanism that allows users to easily lock the sliding part at the desired position without requiring additional tools or complex operations. The locking part can lock the sliding part at different positions along the host, enabling users to self-adjust the device for comfortable wearing.
3Reliability
If the bracket structure is fixed, then manufacturing is simple, but it may cause device damage due to falling from improper fit
Solution Approach 1:
The adjustable bracket structure allows the device to be properly fitted to different head sizes, preventing improper fit that could lead to falling and device damage. The sliding mechanism enables the bracket distance to be adjusted, ensuring secure and safe wearing for each user while maintaining relatively simple manufacturing processes.

AI summary
A head mounted display device includes a host, two sliding parts, two locking parts and two brackets. The host has two connecting bases located on opposite sides of the host. The two sliding parts are respectively slidably connected to the corresponding connecting base. The two locking parts are respectively used to lock the corresponding sliding part in a retracted position or a pulled-out position relative to the corresponding connecting base. The two brackets are respectively pivotally connected to one end of the corresponding sliding part away from the host.
