Manual Cable Stripping Tool With Inclined Bearing Face
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable stripping tools are inefficient in placing the cable within the support head, requiring multiple actions from the operator and lacking ergonomic design, and they do not ensure safe operation during stripping.
Innovation Solution
A manual cable stripping tool with a gripping means adjacent to the knife holder, featuring a bearing face inclined at 45° to 90° for easy cable placement, a retractable cutting blade for safety, and a clip system for quick knife replacement, allowing rapid and ergonomic operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a traditional cable stripping tool is used without a bearing face on the gripping means, then the structure remains simple, but the cable placement requires multiple actions and takes a long time
Solution Approach 1:
The bearing face is pre-configured on the gripping means at an inclination of 45° to 90° relative to the longitudinal axis, allowing the cable to be guided and placed onto the support head in a single motion. This preliminary structural arrangement eliminates the need for multiple placement actions while maintaining overall tool simplicity.
2Ease of operation
If the bearing face is inclined at 45° to 90° on the gripping means, then cable placement becomes rapid and ergonomic, but the gripping means structure becomes more complex
Solution Approach 1:
The bearing face is pre-configured at an optimal inclination angle of 45° to 90° relative to the longitudinal axis of the tool body, enabling the cable to be naturally guided onto the support head during a single placement motion. This preliminary angular configuration reduces the operational steps required while the bearing face itself serves as the guiding structure.
Solution Approach 2:
The bearing face is arranged to project laterally from the support head, creating a three-dimensional guiding surface that receives the cable from the side and directs it onto the support head. This lateral projection and angular arrangement transforms the cable placement from a linear insertion to a guided angular motion, improving ergonomics and speed.
3Reliability
If a non-retractable cutting blade is used, then the tool structure is simpler, but the operator safety is compromised during stripping operations
Solution Approach 1:
The cutting blade is designed to be retractable, allowing it to move between an extended position during cutting operations and a retracted position when not in use. This dynamic configuration protects the operator by hiding the sharp edge when not needed, while the blade mechanism integrates with the existing knife holder structure to minimize added complexity.
4Productivity
If the knife holder cannot be quickly released, then the tool structure is simpler, but the knife replacement time increases
Solution Approach 1:
The knife holder mechanism is segmented into a releasable component that can be quickly released from the tool body without complete disassembly. This segmentation allows the knife to be rapidly replaced by releasing the holder, while the overall tool structure remains intact. The release mechanism integrates with the existing sliding configuration of the knife holder.
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
Facilitates rapid and safe cable stripping with improved ergonomics, allowing quick placement of cables and easy knife changes without disassembling the tool, enhancing user safety and efficiency.
Implementation Method 1
a spring being adapted to move the knife closer to the support and to clamp and secure the cable between these two members
Implementation Method 2
a force F applied to the cable in a direction substantially transverse to the sliding direction of the knife holder acts on the knife holder with an axial force component F1x capable of displacing the knife holder from its advanced position towards its retracted position against the action R of the biasing means

AI summary
The tool comprises a body (2), a head (4), a knife holder (7) which is received in a sliding manner in relation to the body, an incision knife (8) which is supported by the knife holder, a biasing means (32) which acts on the knife holder to displace it towards the head, a gripping means (22) which is rigidly connected to the knife holder; the knife holder (7) is movable between an advanced position in which the knife (8) is moved closer to the head (4) under the action of the biasing means (32) and a retracted position in which the knife (8) is moved away from the head (4) against the action of the biasing means (32). The gripping means (22) is arranged adjacent to the free end of the knife holder and comprises a bearing face (62) adapted to receive the cable to be engaged in the head (4).
