Cable Stripping Length Adjustment for Shielded Wire Precision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable stripping machines require high manual interaction for adjusting stripping lengths, leading to inaccuracies and increased processing time, especially when handling shielded cables in high-voltage applications.
Innovation Solution
A stripping system with a first cutting means and a second cutting means, where the second cutting means is movable relative to the first, allowing for precise and automated adjustment of stripping lengths through a stopping means and rotational movement, enabled by a control unit that can store and recall pre-defined lengths, and optionally utilize a scanner for machine-readable objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual adjustment of stripping length is used, then device complexity is reduced, but manufacturing precision and reliability deteriorate due to inaccurate adjustment
Solution Approach 1:
The patent replaces manual mechanical adjustment with an automated motor-driven system. A motor (24) drives a drive gear (45) that meshes with a length adjustment gear (43) on the stopping means (32), enabling automated, precise positioning of the stopping face (38) relative to the cutting edge (28) without manual intervention, thereby improving stripping length precision while maintaining reasonable device complexity.
Solution Approach 2:
The control unit (60) automatically controls the motor (24) to position the stopping means (32) at the correct location based on stored stripping length data. The system serves itself by automatically adjusting the stripping length without requiring manual measurement or adjustment, improving both precision and efficiency.
2Device complexity
If manual adjustment of stripping length is used, then device complexity is reduced, but productivity deteriorates due to increased processing time
Solution Approach 1:
The control unit (60) stores pre-defined stripping length values in advance. When a cable is to be stripped, the system automatically retrieves the appropriate pre-stored value and positions the stopping means (32) accordingly, eliminating the time-consuming manual measurement and adjustment process, thereby significantly improving productivity.
Solution Approach 2:
The motor-driven automatic positioning system replaces manual adjustment operations, enabling rapid repositioning of the stopping means (32) between different stripping lengths. This automated mechanical system reduces the time required for each stripping operation and allows quick adaptation to different cable types, improving overall productivity.
3Manufacturing precision
If automated stripping length adjustment is implemented, then manufacturing precision and productivity are improved, but device complexity increases
Solution Approach 1:
The control unit (60) serves multiple functions: it stores multiple pre-defined stripping length values, automatically selects the appropriate value based on cable type, controls the motor (24) for positioning, and coordinates the cutting operation. This multi-functionality consolidates what could be separate complex systems into a single integrated control unit, improving precision while limiting the increase in overall device complexity.
Solution Approach 2:
The drive gear (45) acts as an intermediary between the motor (24) and the length adjustment gear (43) on the stopping means (32). This mechanical intermediary translates motor rotation into precise linear positioning of the stopping face (38), enabling accurate control without requiring a complex direct-drive mechanism, thus improving precision while managing device complexity.
4Productivity
If automated stripping length adjustment is implemented, then productivity is improved, but device complexity increases
Solution Approach 1:
The control unit (60) stores multiple pre-defined stripping length values in advance. When processing different cable types, the system automatically retrieves the appropriate pre-stored value and positions the stopping means (32) accordingly, eliminating the time-consuming manual measurement and adjustment process. This preliminary preparation of data significantly improves productivity while keeping the hardware addition minimal.
Solution Approach 2:
The control unit (60) automatically controls the motor (24) to position the stopping means (32) at the correct location based on stored stripping length data. The system serves itself by automatically adjusting the stripping length without requiring manual measurement or adjustment, improving both precision and efficiency while adding only one automated subsystem.
