Cable Stripping Hole Geometry for Deformed Cable Passage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable stripping tools face difficulties in efficiently stripping the sheath of cables with increased diameter portions, as these portions often get caught in the tool's hole due to their larger diameter compared to the tool's opening.
Innovation Solution
A cable stripping tool with a non-circular shaped hole, such as an elliptical shape, and a blade protruding from the inner surface of the hole, which allows the deformed portion of the cable to enter a space portion within the hole, enabling smooth passage and efficient stripping of the cable sheath.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a circular hole is used in the cable stripping tool, then the tool structure is simple and easy to manufacture, but cables with increased diameter portions get caught in the hole and cannot pass through smoothly
Solution Approach 1:
The patent applies asymmetry by changing the hole cross-section from a circular shape to an elliptical shape. This asymmetric geometry creates additional space that allows cables with increased diameter portions to pass through smoothly without getting caught, while maintaining manufacturing simplicity. The elliptical cross-section provides extra clearance in certain directions to accommodate cable deformations.
2Ease of operation
If the hole cross-section is changed to non-circular shape to accommodate deformed cable portions, then cable passage is improved, but the manufacturing complexity increases
Solution Approach 1:
The patent resolves this contradiction by implementing an elliptical cross-section for the hole, which is a simple non-circular shape that can be easily manufactured using conventional machining methods. The elliptical geometry provides the necessary space for deformed cable portions to pass through smoothly while maintaining manufacturing simplicity, thus balancing operational ease with ease of manufacture.

AI summary
A cable stripping tool according to one embodiment is a cable stripping tool that strips a sheath of a cable. The cable stripping tool includes a blade protruding from an inner surface of a hole into which the cable is to be inserted. The sheath of the cable inserted into the hole is cut by the blade when the cable is pulled out from the hole along an extending direction of the cable. A cross-sectional shape of the hole is a non-circular shape in a plane orthogonal to the extending direction. The hole includes a space portion that a deformed portion of the cable inserted into the hole enters.
