Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In DC electrical equipment assemblies, the numerous cables used to electrically couple circuit breaker poles result in a cluttered and difficult-to-install configuration within the DC distribution assembly.
Innovation Solution
A mounting module with electrically non-conductive base portions and conductive straps that couple breaker pole assemblies in series, eliminating the need for multiple cables by using conductive straps to connect breaker posts and pole assemblies, allowing for efficient electrical coupling while maintaining the ability to break excess current flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If numerous cables are used to electrically couple circuit breaker poles in series, then electrical connectivity is achieved, but the DC distribution assembly becomes cluttered and difficult to install
Solution Approach 1:
The patent combines multiple cable connections into a single bus bar structure. The bus bar serves as a common electrical connection point that replaces numerous individual cables, thereby achieving the same electrical connectivity function while dramatically reducing assembly complexity and clutter.
Solution Approach 2:
The bus bar performs multiple functions simultaneously: it provides electrical connectivity between circuit breaker poles, serves as a structural support element, and acts as an organizational framework that simplifies the overall assembly. This multi-functionality eliminates the need for separate cable management components.
2Reliability
If numerous cables are used to electrically couple circuit breaker poles, then electrical connectivity is established, but installation becomes difficult and time-consuming
Solution Approach 1:
By merging multiple cable connections into a single bus bar component, the installation process is simplified from connecting numerous individual cables to connecting a single integrated structure, thereby dramatically improving installation efficiency and productivity.
Solution Approach 2:
The bus bar is pre-configured with connection points and routing paths before installation. This preliminary preparation allows for faster on-site assembly as the structural framework and electrical connection points are already established, eliminating the need for complex field wiring operations.
3Reliability
If cables are used to connect breaker pole assemblies, then electrical coupling is achieved, but the assembly results in a cluttered mass of cables
Solution Approach 1:
The bus bar consolidates multiple cable pathways into a single organized structure with defined routing channels. This merging transforms the chaotic cable mass into a structured, geometrically organized assembly where electrical coupling is maintained while spatial organization is dramatically improved.
