Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate protection circuit is disposed to minimize electric shock effects, then the electronic device is protected from damage, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent extracts the protection function from a separate protection circuit and integrates it directly into the input/output terminal structure. By disposing resistive material at the end portion of the signal pin or ground pin, the protection function is embedded in the terminal itself rather than requiring a separate circuit, thereby reducing device complexity while maintaining reliability
Solution Approach 2:
The resistive material acts as an intermediary element between the external device and the electronic device's internal components. It provides a controlled resistance path that dissipates electric shock energy before it can reach sensitive internal components, achieving protection without complex circuitry
2Reliability
If a separate protection circuit is disposed to minimize electric shock effects, then the electronic device is protected from damage, but the manufacturing cost increases
Solution Approach 1:
The protection function is extracted from a separate protection circuit and integrated into the input/output terminal structure. By disposing resistive material at the end portion of the signal pin or ground pin, the protection function is embedded in the terminal itself rather than requiring a separate circuit, thereby reducing device complexity while maintaining reliability
Solution Approach 2:
The patent merges the protection function with the input/output terminal structure. The resistive material is integrated into the terminal assembly, combining the connection function and protection function into a single integrated component, which simplifies manufacturing and reduces costs compared to adding a separate protection circuit
3Object-affected harmful factors
If resistive material is disposed at the end portion of the signal pin or ground pin, then electric shocks are consumed and removed, but the structure becomes more complex
Solution Approach 1:
The resistive material is disposed only at the end portion of the signal pin or ground pin, providing protection precisely where it is needed - at the point of contact with the external device. This localized approach achieves electric shock absorption without requiring the entire terminal structure to be complex or modified throughout
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
