Flat Cable Holding Member with Folded Stopper
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable holding systems for flat cables are cumbersome and difficult to assemble due to the need for manual winding and precise positioning, especially with thin and soft cables.
Innovation Solution
A cable holding member with a stopper member and housing that allows for easy attachment of a flat cable in a folded state, featuring a positioning section, a stepped part, and a direction control section to facilitate secure attachment without manual folding, along with a flexible structure in the cable to enhance handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If manual winding and positioning of the flat cable is performed, then the cable can be attached to the cable holder, but the assembly process becomes complicated and time-consuming
Solution Approach 1:
The cable holder is pre-formed with a folded configuration and the flat cable is pre-positioned in the folded state within the holder. This preliminary preparation eliminates the need for manual winding and positioning during assembly, allowing workers to simply attach the pre-assembled cable holder to the housing.
Solution Approach 2:
The cable holder's folded structure and positioning features automatically maintain the flat cable in the correct position without requiring manual intervention for winding or positioning. The holder serves itself by providing built-in positioning mechanisms that keep the cable properly aligned during attachment.
2Manufacturing precision
If the flat cable is held by hand for winding, then the cable can be positioned on the cable holder, but optimal positioning becomes difficult due to the thin and soft nature of the cable
Solution Approach 1:
The cable holder acts as an intermediary device between the worker and the flat cable. Instead of directly handling the thin and soft cable, workers attach the pre-formed cable holder which already contains the properly positioned cable. The holder's structure provides the necessary support and positioning that would be difficult to achieve by direct manual manipulation.
Solution Approach 2:
The cable holder is designed with a folded configuration that accommodates the flexible nature of the flat cable. The holder's structure includes features that conform to and support the thin, flexible cable while maintaining precise positioning, leveraging the cable's flexibility rather than fighting against it.
3Reliability
If the tentative holding part is rotated to sandwich the cable end, then the cable end is held securely, but the assembly process becomes more complex
Solution Approach 1:
The functions of the cable supporting part and the tentative holding part are merged into a single integrated cable holder assembly. The folded structure combines the support surface and the holding mechanism into one component that attaches to the housing as a unit, eliminating the need for separate rotation and sandwiching operations.
Solution Approach 2:
The cable holder is pre-assembled with the cable end already secured in the folded configuration before attachment to the housing. This preliminary securing action eliminates the need for post-attachment operations to sandwich or rotate holding parts, as the cable is already firmly held in place.

AI summary
A cable holding member includes a stopper member and a housing. The stopper member has an attachment surface for supporting a flat cable in a folded state. The housing has a mounting surface which is provided at an opening edge of a housing space for housing the stopper member and on which the flat cable is to be placed, and recesses into which protrusions of the flat cable placed on the mounting surface are to be fitted. The flat cable is placed on the mounting surface, and then, the stopper member is inserted into the housing space of the housing. In this way, the stopper member is attached to the housing with the flat cable being supported on the attachment surface.
