Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional manufacturing methods are used to make press components, then the components can be produced with standard materials and geometries, but the components cannot achieve varying material properties or complex geometries required for efficient HPHT sintering
Solution Approach 1:
The patent applies local quality by creating press components with spatially varying material properties through additive manufacturing. Different regions of the component have different densities, compositions, or material types tailored to specific functional requirements - for example, higher density in high-stress areas and lower density in areas requiring thermal insulation or reduced weight.
Solution Approach 2:
The patent utilizes composite materials by combining multiple materials with different properties within a single press component. The additive manufacturing process enables the integration of materials with varying thermal conductivity, electrical conductivity, mechanical strength, and density in a unified structure, allowing optimization of both electrical and thermal performance simultaneously.
2Manufacturing precision
If additive manufacturing is used to create components with varying material properties, then customized properties and complex geometries are achieved, but the manufacturing process becomes more complex
Solution Approach 1:
The patent applies parameter changes by systematically varying material deposition parameters during additive manufacturing - including deposition rate, layer thickness, heating power, and material composition ratios - to achieve the desired spatial distribution of material properties. This enables precise control over density gradients and compositional variations throughout the component.
