Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional virtual reality apparatuses are designed with fixed bonding structure, then structural stability is maintained, but ease of donning and removal deteriorates
Solution Approach 1:
The bonding structure transitions from a fixed state to a dynamically adjustable state through the rotation button mechanism. The first and second bonding bands can be moved relative to each other along the adjustment device, allowing the overall length to be modified. This dynamic capability enables the bonding structure to adapt between a longer state for easy donning and a shorter state for secure fitting, resolving the contradiction between ease of operation and structural stability.
Solution Approach 2:
The invention changes the physical parameter of the bonding structure (length/distance between first end and second end) through mechanical adjustment. By rotating the rotation button, the user activates the adjustment mechanism to modify the distance between the first end of the first bonding band and the second end of the second bonding band. This parameter change allows the bonding structure to be extended for donning and contracted for secure fitting, maintaining stability while improving ease of operation.
2Adaptability or versatility
If the bonding structure length is fixed, then manufacturing simplicity is maintained, but adaptability to different users deteriorates
Solution Approach 1:
The bonding structure incorporates a dynamic adjustment capability through the adjusting device, allowing it to adapt to different head sizes. The first bonding band and second bonding band can be repositioned relative to each other by rotating the rotation button, which drives the adjustment mechanism to change the distance between the first end and second end. This dynamic adaptability enables a single device to fit multiple users with different head circumferences, improving versatility without requiring multiple fixed-size devices.
3Ease of operation
If no adjustment mechanism is provided, then device complexity is reduced, but ease of operation for donning and removal deteriorates
Solution Approach 1:
The adjusting device introduces a dynamic control mechanism that enables easy modification of the bonding structure length. The rotation button serves as a user-friendly interface that, when rotated, activates the adjustment mechanism to move the first and second bonding bands relative to each other. This allows users to quickly extend the bonding structure for donning and contract it for secure fitting, dramatically improving ease of operation despite the added mechanical complexity.
Solution Approach 2:
The adjustment mechanism is designed to be user-operated through the rotation button, allowing users to independently adjust the bonding structure length without requiring external assistance. The mechanical design enables the user's rotational input on the button to directly translate into linear movement of the bonding bands through the adjustment mechanism, providing a self-service capability for easy donning and removal.

AI summary
A head-mounted display includes a display device, a bonding structure connected to the display device, an adjusting mechanism connected to the bonding structure, and a rotation button connected to the adjusting mechanism. When the rotation button is rotated, the length of the bonding structure is changed by the adjusting mechanism.
