Flat Connector Cable Bending Shape Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing electronic endoscope connectors require noise control measures using ferrite cores, which limit flexibility and sturdiness when transitioning to electric cables with noise control functions, making it difficult to maintain a linear state and prevent sagging.
Innovation Solution
A connector design featuring a flat-type connector case with an extension hole, a slide member, and a bend preventing portion that fixes the electric cable in a predetermined bending shape, allowing the cable to be housed and secured within the connector case while maintaining noise control functionality.

Engineering Contradiction Analysis
1Object-affected harmful factors
If a ferrite core is used for noise control measures, then noise reduction is achieved, but flexibility and sturdiness of the cable are compromised
Solution Approach 1:
The invention extracts and removes the ferrite core from the connector structure, replacing it with an electric cable that has integrated noise control functionality through its own construction (shield layer with ferrite compound layer and insulating coating layer). This eliminates the need for the separate ferrite core component while maintaining noise reduction capabilities.
Solution Approach 2:
The invention changes the noise control approach from using a passive ferrite core material to using an active electric cable structure with integrated shielding layers. The cable's own construction (shield layer, ferrite compound layer, insulating coating layer) provides noise control, transforming the noise management function from a separate component to an inherent property of the cable itself.
2Ease of operation
If the cable is extended by a predetermined length from the connector case opening, then ease of connection is improved, but cable sagging and maintenance of linear state become difficult
Solution Approach 1:
The invention introduces a bend preventing portion with a curved surface that guides the cable along a predetermined弯曲 path. The cable is configured to follow this curved trajectory from the connector case opening to the extension point, preventing sagging while maintaining the necessary extended length for easy connection. The curved guide surface ensures the cable maintains a controlled shape rather than hanging loosely.
Solution Approach 2:
The bend preventing portion acts as an intermediary element between the connector case and the extended cable. It provides a structured path that the cable follows, mediating between the fixed connector case and the flexible extended cable, thereby preventing the cable from sagging while still allowing it to extend to the required length.
3Shape
If a slide member with cable bending shape defining portion is added, then cable shape control is improved, but device complexity increases
Solution Approach 1:
The invention merges the cable bending shape defining function into the existing slide member structure. The slide member, which already exists for other functional purposes, is designed to include a cable bending shape defining portion on its surface. This integration allows the slide member to simultaneously perform its original function and guide the cable along the predetermined弯曲 path, avoiding the need for a separate cable guiding component.
Solution Approach 2:
The slide member is designed with multi-functionality, serving both its original purpose and the additional function of defining the cable bending shape. The cable bending shape defining portion on the slide member allows a single component to perform multiple functions, thereby controlling cable shape without significantly increasing overall device complexity.
