Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional bonding structures are used in head-mounted displays, then the display can be worn on the user's head, but the process of donning and removal becomes complex and time-consuming
Solution Approach 1:
The bonding structure incorporates an adjustable mechanism that transforms a static headband into a dynamic one. The driving element can rotate relative to the housing, allowing the bonding structure to change its dimensions dynamically. This enables the user to quickly adjust the size of the bonding structure to match different head sizes, significantly reducing the time and complexity of donning and removal processes.
Solution Approach 2:
The patent implements a mechanism that changes the physical parameter of the bonding structure's length. By rotating the driving element, the distance between the first end and the second end of the bonding structure can be adjusted. This parameter change allows the bonding structure to adapt to different user head sizes, making the donning and removal process simpler and faster without requiring complex adjustments.
2Ease of operation
If an adjustable mechanism is added to change bonding structure size, then ease of donning and removal improves, but device complexity increases
Solution Approach 1:
The adjusting device is designed to be user-operated through a simple rotation action. The user can easily rotate the driving element or rotation button to adjust the bonding structure size without requiring assistance or complex operations. The mechanism serves itself by converting a simple rotational input into the desired dimensional adjustment, minimizing the need for additional control systems or complex adjustment procedures.
Solution Approach 2:
The adjusting function is extracted as a separate, modular component (the driving element and housing assembly) that can be independently operated. This modular approach allows the adjustment mechanism to be integrated into the bonding structure without significantly increasing overall device complexity. The blocking structure selectively constrains the driving element's movement, simplifying the control mechanism while maintaining adjustability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the user to rotate the rotation button with one hand to change the bonding structure's size, facilitating easy wear and removal of the head-mounted display.
Implementation Method 1
The driving element is rotatably disposed in the housing, and connected to the first bonding band and the second bonding band. The blocking structure allows the driving element to rotate in a first rotation direction, and is configured to selectively block the driving element from rotating in a second rotation direction
Implementation Method 2
The rotation button is rotatably disposed in the housing, and connected to the driving element. When the rotation button is rotated, the rotation button drives the driving element to rotate relative to the blocking structure, and the distance between the first end and the second end can be adjusted by the driving element
Data Source
AI summary
A head-mounted display includes a display device, a bonding structure connected to the display device, a driving element connected to the bonding structure, and a rotation button connected to the driving element. When the rotation button is rotated, the length of the bonding structure is changed by the driving element.
