Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the insulation part is made only of insulating material to simplify the structure, then the manufacturing cost is reduced and structure is simplified, but interference between contact parts occurs during high-frequency signal transmission causing signal loss
Solution Approach 1:
The insulation part is constructed using composite materials combining insulating material with conductive particles. This creates a material that simultaneously provides electrical insulation between adjacent contact parts while allowing controlled signal transmission through the insulating support part, thereby preventing signal interference without requiring complex multi-component structures
Solution Approach 2:
The insulating support part has different electrical properties in different directions: it provides insulation in the horizontal direction between adjacent contact parts, while allowing signal transmission in the vertical direction through the thickness of the part. This anisotropic property enables the single component to fulfill multiple functional requirements
2Adaptability or versatility
If conductive particles are arranged in the thickness direction of the insulating support part to enable flexible connection, then mechanical shock and deformation are absorbed, but signal loss occurs at high frequencies due to interference between contact parts
Solution Approach 1:
The insulating support part combines insulating material with conductive particles arranged in the thickness direction, creating a composite that maintains flexibility for absorbing mechanical shock while the insulating material component prevents lateral interference between contact parts during high-frequency signal transmission
Solution Approach 2:
The conductive particles are locally arranged in the thickness direction to provide flexibility and shock absorption, while the insulating material provides lateral insulation. This localized functional differentiation within a single component resolves the contradiction between flexibility and signal transmission quality
