Engineering Contradiction Analysis
1Volume of moving object
If a portable display device is designed with a compact structure, then storage and portability are facilitated, but durability and rigidity deteriorate
Solution Approach 1:
The frame is divided into multiple beam structures (first beam, second beam, third beam, fourth beam) arranged in a specific pattern. These segmented beams work together to provide enhanced rigidity and strength while maintaining a compact overall structure, resolving the contradiction between compactness and structural strength.
Solution Approach 2:
The frame utilizes a composite structure combining multiple beam elements with different orientations and configurations. This composite arrangement creates a rigid framework that maintains structural integrity in a compact form factor, addressing both the portability and durability requirements.
2Temperature
If heat dissipation structures are added to portable display devices, then heat dissipation performance is improved, but device complexity increases
Solution Approach 1:
The beam structure of the frame serves multiple functions: it provides structural support for device rigidity and simultaneously acts as a heat dissipation pathway. By integrating these two functions into a single structural element, the design improves heat dissipation without significantly increasing device complexity.
Solution Approach 2:
The heat dissipation function is merged with the structural frame rather than being implemented as a separate component. The beam structure itself conducts and distributes heat, combining mechanical support and thermal management into one integrated system.
