Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional electrical connectors are used in complex electronic devices, then device functionality is achieved, but signal transmission efficiency deteriorates due to noise and disturbances
Solution Approach 1:
The patent introduces a specialized cable assembly with a metallic layer (aluminum foil) as an intermediary shielding element between the bonding pads and external environment. This metallic layer acts as a mediator that blocks noise and electromagnetic disturbances from affecting signal transmission, thereby improving signal transmission efficiency in complex electronic devices.
Solution Approach 2:
The patent converts the potentially harmful effect of electromagnetic interference into a beneficial shielding mechanism. By incorporating the metallic layer that reflects and blocks noise, the design transforms the challenge of noise protection into an active feature that enhances signal integrity and transmission efficiency.
2Area of stationary object
If bonding pads are arranged closely to reduce size, then device compactness is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent optimizes the geometric parameters of bonding pads, including their size, shape, and spacing arrangement. By carefully controlling these parameters and maintaining equal center distances between adjacent bonding pads, the design achieves compact wiring region area while managing manufacturing precision requirements through standardized dimensional specifications.
3Ease of operation
If cable flexibility is increased for ease of installation, then ease of operation is improved, but structural stability may deteriorate
Solution Approach 1:
The patent employs a composite cable structure combining plastic insulation layer and metallic shielding layer. This composite design provides both flexibility for easy installation and structural stability for reliable connection. The plastic layer offers flexibility and insulation, while the metallic layer provides structural integrity and electromagnetic shielding, resolving the contradiction between flexibility and stability.
