Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cable connector assemblies are complex and costly to manufacture, requiring specialized cable management and prone to damage due to the difficulty in protecting the outgoing cable terminals, which are easily bent and susceptible to wear.
Innovation Solution
A flexible cable connector assembly featuring an insulative body with terminal slots, a printed circuit board (PCB) with welding parts, a flexible cable with conductive shielding film for protection and shielding against crosstalk, and a protective film that covers the cable to prevent damage and wear, with a wire slot defined by the PCB and insulative body to pass the cable and film through.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional cable management and welding processes are used to connect the cable to conductive terminals, then the cable connector assembly can be manufactured, but the manufacturing process becomes complex and costly
Solution Approach 1:
The patent replaces the conventional mechanical welding process with a snap-fit mechanical connection system. The cable connector assembly includes a housing with a cable retention feature that mechanically secures the cable directly to the conductive terminals without requiring welding equipment or processes, thereby simplifying manufacturing while maintaining connection reliability
Solution Approach 2:
The cable retention feature is integrated into the housing structure itself, allowing the housing to automatically secure and position the cable during assembly without requiring separate cable management components or specialized welding fixtures, reducing both equipment and process complexity
2Device complexity
If the cable is held by the cover and insulative body without additional protection, then the assembly is simple, but the outgoing terminal of the cable is easily bent and damaged
Solution Approach 1:
The cable retention feature is designed to provide pre-positioning and support for the cable outgoing terminal before it can be subjected to bending forces. The retention feature includes a curved or contoured surface that cradles the cable, preventing it from bending sharply or becoming misaligned during subsequent handling and installation, thereby protecting the terminal from damage
Solution Approach 2:
The retention feature incorporates a flexible or elastomeric component that can deform to accommodate the cable while providing gentle restraint. This flexible element conforms to the cable shape and provides continuous support, preventing sharp bends and reducing stress concentration at the outgoing terminal
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution simplifies the manufacturing process, protects the cable from damage and wear, and reduces electrical interference by using a conductive shielding film, enhancing the reliability and efficiency of the connector assembly.
Implementation Method 1
the protective film is a conductive shielding film containing high conductive materials, and when a plurality of conductors of the flexible cable are transmitting signals, the protective film provides proper shielding to eliminate the crosstalk among the conductors as well as reduces the electrical interference from the surrounding
