Integrated Busbar Module Voltage Detection Housing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing busbar modules require complex routing and connection of voltage detection lines during assembly, which complicates the assembly process and increases time and risk of damage.
Innovation Solution
The busbar module integrates voltage detection conductors directly with the housing case, either as printed circuit members on the surface or buried within, eliminating the need for external routing and enhancing assembly ease by forming them from covers to frame bodies via hinges and connection holes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If voltage detection lines are routed externally to connect busbars and housing case, then connection functionality is achieved, but assembly complexity increases and assembly time increases
Solution Approach 1:
The voltage detection conductors are integrated directly into the housing case structure, merging the housing case and voltage detection lines into a single unified component. This eliminates the need for separate routing and connection steps, thereby reducing assembly complexity and assembly time.
2Reliability
If voltage detection lines are routed externally, then voltage detection function is achieved, but risk of damage increases due to external exposure
Solution Approach 1:
By integrating the voltage detection conductors within the housing case structure, the conductors are protected from external damage risks such as mechanical stress, environmental exposure, and accidental disconnection, thereby improving reliability and reducing the risk of damage.
