Solution Overview
Problem
Existing electronic modules face challenges in controlling the distance between heat radiation surfaces and external connection terminals, leading to potential insulation issues and short-circuiting, especially when dealing with high voltage applications.
Innovation Solution
The electronic module design includes internal connection terminals that pass through external connection terminals, allowing precise control of distances between boards and electronic elements, preventing short-circuiting by adjusting the length and position of these internal terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the external connection terminal is bent to connect to the board, then the connection is achieved, but the insulation distance cannot be secured and may contact other electronic elements
Solution Approach 1:
The connection structure is divided into separate functional segments: the external connection terminal, the internal connection terminal, and the board with wiring. The internal connection terminal acts as an intermediate connector that passes through the external connection terminal, creating distinct insulation zones. This segmentation allows each component to perform its function independently while maintaining proper insulation distances.
Solution Approach 2:
The internal connection terminal serves as an intermediary element between the external connection terminal and the board wiring. It provides a controlled transition point that ensures insulation distance is maintained while enabling electrical connection. The intermediary structure prevents direct contact between the external terminal and sensitive board elements.
2Reliability
If the external connection terminal is arranged at an intermediate position in thickness direction between heat radiation members, then insulation distance is secured, but control of distance between external connection terminal and board becomes difficult
Solution Approach 1:
The internal connection terminal is designed to automatically define the positioning relationship between components. By having the internal terminal pass through the external terminal and connect to the board, the structure self-establishes the correct distances without requiring complex external positioning mechanisms. The terminal itself serves as the reference for maintaining proper insulation distances.
Solution Approach 2:
The internal connection terminal serves as an intermediary element between the external connection terminal and the board wiring. It provides a controlled transition point that ensures insulation distance is maintained while enabling electrical connection. The intermediary structure prevents direct contact between the external terminal and sensitive board elements.
