Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Shield connectors used in hybrid and electric vehicles face challenges in heat dissipation due to increased heat generation from large current supply, leading to the need for enlargement of terminals and wires, which is undesirable.
Innovation Solution
A connector design featuring a housing with inclined slope portions and breathable films in through holes above and below the terminal, facilitating heat dissipation through natural convection while preventing enlargement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the terminal and inner conductor are enlarged to improve heat dissipation, then the dissipation performance is improved, but the connector size is enlarged
Solution Approach 1:
The patent introduces a breathable film in the upper through hole of the housing to enable heat dissipation in the vertical dimension through natural convection. This allows heat to be dissipated upward without requiring enlargement of the terminal or inner conductor in the horizontal dimension, thus resolving the contradiction between heat dissipation performance and connector size.
Solution Approach 2:
The patent utilizes natural convection (a pneumatic principle) by providing a breathable film that allows air flow through the housing. The air circulation created by natural convection currents enables efficient heat dissipation from the terminal and inner conductor without requiring increased component dimensions, thereby maintaining compact connector size while improving thermal management.
2Power
If the terminal and inner conductor are enlarged to handle large current, then the current carrying capacity is improved, but the connector size is enlarged
Solution Approach 1:
The patent converts the harmful effect of heat generation from large current into a beneficial natural convection current. The breathable film allows the heat generated by high current to drive air circulation, which in turn enhances cooling efficiency. This enables the connector to handle large currents without requiring oversized terminals or conductors.
3Temperature
If the terminal size is increased to improve heat dissipation, then the dissipation performance is improved, but the device complexity increases
Solution Approach 1:
The patent extracts the heat dissipation function from the terminal structure itself and relocates it to a separate breathable film component in the housing. This separation allows the terminal to maintain its original size while the housing provides the heat dissipation pathway through natural convection, thereby improving heat dissipation without increasing terminal size or overall device complexity.
