Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a locking structure is added to fix the telescopic arms after adjustment, then the stability of the head mount display support is improved, but the device complexity increases and ease of operation deteriorates
Solution Approach 1:
The patent combines the adjustment function and locking function into a single integrated mechanism. The telescopic arm itself serves as both the adjustment component and the locking component, eliminating the need for separate locking structures. When the telescopic arm is pressed, it can be adjusted to different positions, and when released, it automatically locks at the desired position, achieving both adjustment and stability through one unified structure.
Solution Approach 2:
The telescopic arm has self-locking capability through its elastic deformation properties. When the user presses the telescopic arm to adjust it, the elastic material stores energy, and when released, the elastic recovery force automatically maintains the arm at the adjusted position without requiring additional locking mechanisms. This self-service locking mechanism simplifies the overall structure while ensuring stability.
2Stability of the object's composition
If a locking structure is added to fix the telescopic arms after adjustment, then the stability of the head mount display support is improved, but the ease of operation deteriorates
Solution Approach 1:
The adjustment and locking operations are merged into a single action. The user only needs to press the telescopic arm to adjust it to the desired position, and the arm automatically locks when released. This eliminates the need for separate locking operations, significantly improving ease of operation while maintaining stability.
Solution Approach 2:
The telescopic arm performs both adjustment and locking functions through its inherent elastic properties. The user simply needs to apply pressure to adjust the position, and the elastic recovery automatically provides the locking function. This self-service mechanism eliminates complex manual locking operations, making the device very easy to operate while ensuring stable positioning.
3Adaptability or versatility
If the telescopic arms are made adjustable to accommodate different head shapes, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The head mount display support is divided into modular telescopic arm components that can independently adjust their length. Each telescopic arm consists of segmented sections that can be extended or retracted, allowing the overall structure to adapt to different head sizes and shapes. This segmentation enables adjustability while keeping each individual component relatively simple in structure.
Solution Approach 2:
The telescopic arms are designed with dynamic adjustability, allowing users to modify the arm length according to their head shape. The arms can transition between different extended states to accommodate various head circumferences. This dynamic capability provides high adaptability while using relatively simple telescopic mechanisms rather than complex multi-component adjustment systems.

AI summary
A head mount display support and a head mount display. The head mount display support comprises a support main body (11), a knob shaft (131), an adjustment gear (12) and a self-locking mechanism; the support main body (11) comprises two telescopic arms (111), and the two telescopic arms (111) are provid-ed to overlap each other; the adjustment gear (12) is fixedly sleeved on the knob shaft (131), and when the knob shaft (131) is pressed, the adjustment gear (12) is driven by the knob shaft (131) to move to the overlapping part (1111) of the two telescopic arms (111), so that the two telescopic arms (111) move towards or away from each other; the self-locking mechanism comprises a rear shell (141), an elastic member (15) and a locking member (16); and the self-lock-ing structure is used for locking relative positions of the two tele-scopic arms (111). The head mount display support and the head mount display can be applicable to various shapes of heads wearing same, facilitate the adjustment of the shape of the head mount dis-play support and facilitate the locking of the adjusted head mount display support.
