Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable connectors face challenges in safe transportation, high assembly costs, and electrical safety due to lack of pre-fabrication and space-saving design, with existing solutions either risking damage during transport or requiring complex cascading arrangements.
Innovation Solution
A cable connector with diagonally offset through-openings in L-shaped legs allows for pre-assembled, compact, and safe multi-row connections, optimizing clearance and creepage distances for universal use and reduced assembly effort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If cable ends are stripped and positioned close together before insertion, then assembly is simplified, but risk of short circuits and damage during transport increases
Solution Approach 1:
The connector body is divided into multiple independent receiving openings, each capable of individually receiving and isolating cable ends. This segmentation allows cables to be positioned close together for easy assembly while maintaining electrical isolation between them, preventing short circuits during transport and installation.
Solution Approach 2:
The connector body acts as an intermediary structure that receives and positions cable ends in isolated receiving openings. This intermediary design enables simplified assembly by providing pre-defined positioning while simultaneously preventing direct contact between adjacent cables, thereby eliminating short circuit risks.
2Ease of operation
If cable ends protrude beyond the connector for plug-in function, then connection capability is achieved, but damage risk during transport increases
Solution Approach 1:
The connector body is designed with receiving openings that preliminarily position and protect cable ends before the actual plug-in operation. This preliminary action allows the cable ends to be securely held within the connector structure during transport, preventing damage while maintaining the capability for subsequent connection operations.
3Reliability
If clearances and creepage distances are increased for electrical safety, then insulation performance improves, but geometric dimensions and space utilization worsen
Solution Approach 1:
The connector body provides different clearance and creepage distance configurations for different receiving openings based on local requirements. This local quality approach allows optimization of insulation performance in specific areas where cable ends are positioned close together, while maintaining compact overall dimensions by not uniformly increasing clearances throughout the entire connector structure.
