Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic component protection structures require complex configurations, such as insulating members or ground connections, to effectively protect against static electricity, which can be cumbersome and inefficient.
Innovation Solution
A simple configuration involving a conductive elastic member exposed between a base member and a case member, which surrounds the circuit board and ground member, allowing static electricity to be directed away from electronic components without the need for additional insulation or external ground connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional protection structures using insulating members or ground connections are used, then electronic components are protected from static electricity, but the configuration becomes complicated
Solution Approach 1:
The conductive elastic member combines multiple functions into a single component: it provides static electricity protection through its conductivity, ensures electrical connection between case members through its elastic contact properties, and eliminates the need for separate insulating members or external ground connections. This merging of functions directly reduces configuration complexity while maintaining protection reliability
Solution Approach 2:
The conductive elastic member utilizes its own inherent properties (conductivity and elasticity) to provide protection without requiring external ground connections or additional insulating components. The member serves itself by creating the necessary electrical path through its elastic contact with case members, eliminating dependency on external grounding systems
2Reliability
If conductive packing connected to ground terminal is used, then corona discharging is suppressed, but external ground connection is required
Solution Approach 1:
The conductive elastic member creates its own electrical path through elastic contact with the case members, eliminating the need for external ground connections. The member's inherent conductivity and elastic properties allow it to self-establish the necessary electrical connection for corona discharging suppression without requiring external grounding infrastructure
Solution Approach 2:
The invention extracts the grounding function from the external environment and embeds it within the housing structure itself. The conductive elastic member acts as an internal grounding mechanism that eliminates dependency on external ground terminals, simplifying installation and operation

AI summary
An electronic-component-protection structure which can protect, with a simple configuration, an electronic component from static electricity that may be charged in a case member. A ground member having conductivity is integrally formed with a circuit board or electrically connected to the circuit board, wherein the circuit board has an electronic component mounted thereon. A housing includes a base member and a case member and accommodates the circuit board and a ground member. A sealing member, which is a conductive elastic member disposed between the base member and the case member, is at least partly exposed to the outside of the housing.
