Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Power modules often require additional auxiliary terminals for monitoring and protection, which occupy space and increase costs, and existing solutions do not provide a simple and cost-effective way to install these terminals.
Innovation Solution
A housing for power modules with an interconnecting member featuring a power terminal connector part and an auxiliary terminal connector part connected by a spring part, allowing for easy installation of auxiliary terminals without significant additional costs, where the spring part is elastically bent to guide the auxiliary terminal connector part to the appropriate position relative to the power terminal area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional auxiliary terminals are provided on the housing, then monitoring and protection functions are improved, but device complexity and manufacturing costs increase
Solution Approach 1:
The patent combines multiple terminal functions into a single integrated housing structure. The auxiliary terminals are integrated directly into the housing body rather than being separate components, merging the housing structure with the terminal provision function. This reduces overall device complexity while maintaining the monitoring and protection capabilities provided by the auxiliary terminals.
Solution Approach 2:
The housing structure is designed to serve multiple functions simultaneously: it provides mechanical protection for internal components, establishes electrical connections through power terminals, and enables monitoring functions through auxiliary terminals. This multi-functionality approach eliminates the need for separate dedicated structures for each function, thereby reducing complexity while improving reliability.
2Reliability
If auxiliary terminals are installed using conventional methods, then terminal functionality is achieved, but assembly time and manufacturing costs increase
Solution Approach 1:
The auxiliary terminals are pre-integrated into the housing structure during housing manufacturing, rather than being installed separately during final assembly. This preliminary action of incorporating terminals into the housing body before final assembly significantly reduces assembly time while ensuring proper terminal functionality and electrical connections.
Solution Approach 2:
The housing manufacturing process is merged with the terminal installation process. By integrating the auxiliary terminals directly into the housing structure during housing production, the patent eliminates the need for separate terminal installation steps, thereby improving productivity without compromising terminal functionality.
3Reliability
If space is allocated for additional auxiliary terminals, then monitoring capabilities are improved, but available space for other components is reduced
Solution Approach 1:
The auxiliary terminals are arranged in a three-dimensional configuration on the housing surface, utilizing vertical and angular dimensions rather than only horizontal plane space. This dimensional approach allows monitoring capabilities to be added without proportionally increasing the footprint area, effectively using space more efficiently.
Solution Approach 2:
The housing structure is designed with localized terminal areas where auxiliary terminals are positioned in specific regions optimized for their function. This local optimization allows monitoring capabilities to be added in specific zones without uniformly reducing available space across the entire housing, thereby maintaining area efficiency while improving reliability.
