Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a support layer with through parts and metal layers is used to improve tensile strength, then mechanical integrity is improved, but device complexity increases
Solution Approach 1:
The patent applies composite materials by combining a support layer with through parts and metal layers to create a composite substrate structure. This composite construction provides enhanced tensile strength and mechanical integrity while maintaining a manageable structural complexity through systematic design of the through parts and metal layer arrangement.
Solution Approach 2:
The support layer is segmented into multiple through parts that are spaced apart and alternately disposed, creating a modular structure. This segmentation allows the tensile strength to be distributed across multiple reinforcement points rather than requiring a single complex reinforcement system, thereby improving strength while controlling overall structure complexity.
2Reliability
If metal layers are added to the support layer to enhance mechanical integrity, then reliability is improved, but manufacturing complexity increases
Solution Approach 1:
The through parts are formed in the support layer before the metal layers are deposited. This preliminary action creates pre-defined pathways and structural frameworks that guide subsequent manufacturing steps, making the overall process more manageable and less complex than attempting to create the complete structure in a single step.
Solution Approach 2:
The patent extends the structure into the third dimension by creating through parts that penetrate the support layer and alternating metal layers on opposite surfaces. This dimensional approach distributes manufacturing complexity across multiple layers and surfaces rather than requiring complex three-dimensional forming in a single operation, thereby improving reliability while maintaining ease of manufacture.
