Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the operation part is made of metal to suppress deformation and damage, then strength is improved, but electrostatic discharge can flow to electric circuits and image detecting elements causing damage or malfunction
Solution Approach 1:
The patent introduces an insulating substrate as an intermediary between the metal operation part and the housing. This substrate acts as a mediator that mechanically supports the operation part while electrically isolating it from the housing, preventing electrostatic discharge from reaching the metal part and subsequently the electric circuits.
Solution Approach 2:
The patent segments the operation part structure into distinct functional layers: the metal operation part for strength, the insulating substrate for electrical isolation, and the housing for structural support. This segmentation allows each component to fulfill its specific function without interfering with others, particularly preventing the harmful electrical connection between metal parts and circuits.
2Ease of operation
If buttons and display part are connected to internal electric substrate through wiring, then operational functionality is improved, but voltage fluctuation due to discharge is transmitted to the electric substrate causing breakage or noise
Solution Approach 1:
The insulating substrate serves as a mediator that blocks the transmission of voltage fluctuations from electrostatic discharge to the electric substrate. By positioning this insulating layer between the metal operation part (where discharge occurs) and the internal electric substrate, the patent prevents harmful electrical signals from reaching sensitive electronic components while maintaining operational connectivity through controlled wiring paths.
