Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stress or pressure
If a conventional pressure-exerting device is used, then the structure is simple, but the pressure distribution is uneven and the central region receives insufficient pressure
Solution Approach 1:
The pressure-exerting device is divided into multiple functional components: a pressure-exerting member for applying pressure, a pressing elastic sheet for distributing pressure evenly, and a support structure for stability. This segmentation allows each component to specialize in a specific function, achieving uniform pressure distribution while maintaining reasonable structural complexity.
Solution Approach 2:
The pressing elastic sheet is positioned specifically at the central region of the pressure-exerting member, creating a localized quality improvement. This local placement ensures that the central region receives adequate pressure through the elastic sheet's compression, while the peripheral regions are handled by the pressure-exerting member's contact surface.
2Temperature
If a large heat dissipating plate is used, then heat dissipation effectiveness is improved, but it obstructs the pressure-exerting device from applying pressure from the top side
Solution Approach 1:
The support structure extends in a direction perpendicular to the heat dissipating plate, creating a three-dimensional configuration. This dimensional change allows the pressure-exerting device to apply pressure from the top side while the heat dissipating plate remains in place, eliminating the obstruction problem through spatial reconfiguration.
Solution Approach 2:
The support structure acts as an intermediary element between the pressure-exerting device and the heat dissipating plate. It provides a pathway for pressure transmission while allowing the heat dissipating plate to maintain its position, effectively mediating the conflict between pressure application and heat dissipation requirements.
3Reliability
If the pressure-exerting device applies pressure from the top side, then electrical connection is achieved, but the heat dissipating plate interferes with this pressure application
Solution Approach 1:
By extending the support structure in a direction perpendicular to the heat dissipating plate, the design creates a three-dimensional space that allows pressure application from the top side without interference from the heat dissipating plate, ensuring reliable electrical connection while eliminating the harmful interference.
Solution Approach 2:
The support structure extracts or separates the pressure application function from the heat dissipating plate's space. By providing a dedicated structural element that extends perpendicular to the plate, the design removes the interference between the two functions, allowing independent operation of both pressure application and heat dissipation.
