Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional hinge mechanism is used to connect the display part to the body, then the structure is simple, but the up-down movement flexibility is restricted and heat dissipation is insufficient
Solution Approach 1:
The hinge assembly is divided into multiple functional components: a hinge shaft for rotation, a first coupling part extending from the hinge shaft, a second coupling part rotatably coupled to the hinge shaft, and a foot plate pivotably coupled to the second coupling part. This segmentation allows each component to perform a specific function while collectively providing flexible up-down movement.
Solution Approach 2:
The hinge mechanism employs multiple rotational and pivotal joints that enable dynamic movement. The display part can rotate with respect to the body through the hinge shaft, and the foot plate can pivot according to the rotation of the hinge shaft, providing adaptive positioning and enhanced movement flexibility.
2Ease of operation
If the display part is fixed to the body, then the structure is stable, but the screen interaction experience is reduced
Solution Approach 1:
The hinge assembly enables the display part to dynamically adjust its position relative to the body through rotational and pivotal movements. Users can tilt and position the display at optimal angles for interaction, enhancing ease of operation while the mechanism maintains structural stability through its coupled components.
Solution Approach 2:
The hinge mechanism allows changes in the angular parameters of the display part relative to the body. By adjusting the rotation angle of the hinge shaft and the pivot angle of the foot plate, the display can be positioned at various angles to optimize screen interaction while maintaining stable connection.
3Temperature
If a compact hinge structure is used, then the device size is reduced, but heat dissipation capability is insufficient
Solution Approach 1:
The foot plate acts as an intermediary component that extends from the second coupling part. This intermediary structure provides additional surface area for heat dissipation while maintaining a compact overall design, as the foot plate can be positioned to optimize thermal management without significantly increasing the hinge assembly volume.
