Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If resin is used as channel plates for temperature adjustment, then the device achieves good sealing performance and ease of manufacture, but creep deformation occurs under time-dependent load
Solution Approach 1:
The invention uses a composite structure where a resin channel plate is combined with a metal reinforcement plate. The resin provides sealing performance and ease of manufacture, while the metal plate provides high compressive strength to prevent creep deformation. This composite approach allows both materials to contribute their advantageous properties to the overall structure.
Solution Approach 2:
The channel plate is divided into two functional segments: the resin channel plate for sealing and fluid passage, and the metal reinforcement plate for structural support. This segmentation allows each component to be optimized for its specific function while working together as an integrated assembly.
2Device complexity
If resin channel plates are used in temperature adjustment devices, then the device structure is simple and cost-effective, but large creep deformation occurs due to time-dependent load
Solution Approach 1:
By combining resin and metal materials in a composite structure, the invention achieves high compressive strength from the metal plate while maintaining the overall simplicity and cost-effectiveness of the device. The metal reinforcement plate is strategically positioned to provide strength where needed without adding excessive complexity.
Solution Approach 2:
The metal reinforcement plate acts as an intermediary element between the resin channel plate and the external loading forces. It mediates the mechanical stress, protecting the resin material from direct exposure to high compressive loads that would cause creep deformation.
3Ease of manufacture
If resin is used as the channel plate material, then the device is easy to manufacture with good sealing, but the sealing performance deteriorates over time due to creep deformation
Solution Approach 1:
The composite structure of resin channel plate with metal reinforcement maintains sealing performance reliability over time. The metal plate prevents creep deformation that would otherwise compromise the sealing interface, while the resin maintains its sealing properties without undergoing time-dependent deformation.
Solution Approach 2:
The metal reinforcement plate provides beforehand cushioning against creep deformation forces. By pre-positioning this high-strength element, the structure is prepared in advance to resist time-dependent loads that would otherwise cause sealing failure, thereby maintaining reliability throughout the device's operational life.
