Flexible Flat Cable Testing System Parallel Wire Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for testing flexible flat cables are inefficient as they require manual testing of each wire with a multimeter to detect quality defects, leading to low test efficiency and potential waste due to broken wires.
Innovation Solution
A flexible flat cable testing system comprising a first connector, a second connector, a short circuit test unit, a potential reader, and a judgment unit that simultaneously tests all wires by electrically contacting both ends and determining the quality based on potential levels, allowing for on-line detection and quick identification of broken wires.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual testing of each wire with a multimeter is used, then testing can be performed, but test efficiency is very low
Solution Approach 1:
The patent combines multiple testing functions into a single automated testing system that can test all wires in parallel. The system integrates the connector, test unit, and judgment unit into one unified device that simultaneously tests all wires, replacing the manual sequential testing process with a single automated operation that achieves both high productivity and time efficiency.
Solution Approach 2:
The patent replaces the manual mechanical testing process (using a multimeter and human operation) with an automated electronic testing system. The automated system uses electronic signals to test wire continuity and quality without requiring manual intervention, thereby dramatically improving test efficiency and reducing testing time.
2Productivity
If all wires are tested simultaneously using the automated system, then test efficiency is improved, but device complexity increases
Solution Approach 1:
The testing system is designed with multi-functionality to justify its complexity. It can test multiple wires simultaneously, identify broken wires, detect quality defects, and provide automated judgment all through a single integrated system. This universal capability allows one device to perform what would otherwise require multiple separate testing operations.
Solution Approach 2:
The automated testing system performs self-service by automatically conducting all testing operations without manual intervention. The system independently applies test signals, measures wire continuity, analyzes results, and determines quality status, thereby eliminating the need for operators to manually test each wire with a multimeter.
3Productivity
If manual testing is used, then equipment cost is low, but test efficiency is very low
Solution Approach 1:
The testing system is segmented into distinct functional modules: a connector for electrical contact, a test unit for signal generation and measurement, and a judgment unit for quality determination. This segmentation allows for easier manufacturing, assembly, and maintenance of the system while enabling parallel testing capabilities that dramatically improve productivity.

AI summary
A flexible flat cable testing system includes a first connector including a row of first contacts electrically contacting first ends of a row of wires of a flexible flat cable, a second connector including a row of second contacts electrically contacting second ends of the row of wires, a short circuit test unit including output ports electrically connected to the row of first contacts and input ports electrically connected to the row of second contacts, a potential reader reading a potential level of each of the input ports, and a judgment unit determining whether or not a quality of the flexible flat cable is qualified according to the potential level of each of the input ports. The judgment unit determines that the quality of the flexible flat cable is qualified if the potential level of each of the input ports is equal to a high level output by each of the output ports.
