Cable Stripping Tool Compact Handle Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cable stripping tools require a long handle due to the spring suspension of the cable retaining bracket, making them impractical for use in tight spaces and posing a risk of injury from exposed tension springs.
Innovation Solution
The tension spring is integrated into a cavity within the sliding tab of the cable retention bracket, allowing for a shorter handle design and concealing the spring to prevent injuries, while maintaining the necessary length for ergonomic comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the tension spring is exposed for suspension of the cable retaining bracket, then the bracket can be easily suspended and moved, but the user can be injured by contact with the spring or the spring can get caught on objects
Solution Approach 1:
The tension spring is integrated into a cavity within the sliding tab of the cable retention bracket, nesting the spring inside the bracket structure. This eliminates exposure of the spring while maintaining its suspension function, as the spring remains contained within the hollow body of the sliding tab throughout operation.
2Reliability
If a long handle is used for spring suspension, then the spring can be adequately suspended, but the tool cannot be used in tight spaces and junction boxes close to ceilings
Solution Approach 1:
The tension spring is nested within the hollow body of the sliding tab, utilizing the internal cavity space rather than requiring external handle length. This integration allows adequate spring suspension and deflection within the compact handle structure, enabling use in tight spaces while maintaining reliable spring function.
3Length of moving object
If the tension spring is integrated into the sliding tab cavity, then the handle can be shortened and the spring concealed, but the spring must still maintain adequate length for ergonomic operation
Solution Approach 1:
The spring is arranged in a three-dimensional cavity within the sliding tab, utilizing vertical and lateral space rather than extending the handle length. The spring extends from the front area of the sliding tab to the rear of the cavity, maintaining adequate length for ergonomic operation while being contained within the compact handle structure.

Function Achieved in This Case
This design enables a more compact cable stripping tool that can be used in narrow spaces without the risk of spring-related injuries, and allows for additional tools to be integrated into the handle, such as a retractable knife blade.
Implementation Method 1
a tension spring (30) extending between a first suspension point (16) on the sliding tab (21) and a second suspension point (25) in the handle body (10)

AI summary
The tool has a gripping body (10), and a cable retaining bracket (20) that is adjustably supported with a movable plate in an opened recess and in a closed receiving channel in the body against the force of a tension spring (30). The spring extends between a suspension point (25) at bracket and another suspension point (16) at the body. The plate is partially formed as a hollow body with a hollow space, in which the spring is arranged.
