Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual techniques are used for electrical cable jacket and insulation removal, then the device complexity is reduced, but the manufacturing precision and reliability deteriorate due to inaccurate and imprecise results
Solution Approach 1:
The patent replaces manual mechanical operations with an automated system that uses motors to rotate the working plate and actuate the cutting tool. The first motor rotates the working plate at controlled speeds, while the second motor actuates the cutting tool to open and close, eliminating manual manipulation and improving cutting precision through automated control.
Solution Approach 2:
The system incorporates sensors that automatically detect cable parameters and feed this information back to the controller, which adjusts the cutting parameters accordingly. This self-adjusting mechanism allows the system to adapt to different cable types without manual intervention, maintaining high precision across various cable configurations.
2Ease of operation
If manual techniques are used for electrical cable preparation, then the ease of operation is improved, but the reliability deteriorates due to damaged conductors and poor electrical connections
Solution Approach 1:
The automated system replaces manual cable preparation operations with motor-driven cutting tools that precisely control the cutting depth and speed. This substitution eliminates the variability and human error associated with manual techniques, ensuring consistent, reliable cuts that prevent conductor damage and ensure proper electrical connections.
Solution Approach 2:
The system uses sensors to detect cable characteristics and provides feedback to the controller, which automatically adjusts cutting parameters. This closed-loop control ensures that the cutting process adapts to different cable types, maintaining reliability by preventing both insufficient cutting and excessive cutting that could damage conductors.
3Manufacturing precision
If automated cutting tools are used, then the manufacturing precision is improved, but the device complexity increases due to multiple motors and control systems
Solution Approach 1:
The working plate serves multiple functions: it supports the cutting tool, acts as a rotating platform driven by the first motor, and provides a mounting surface for sensors. The cutting tool itself is multi-functional, capable of cutting through different cable layers (jacket, insulation, grounding wires) in a single operation. This multi-functionality reduces the need for separate components and operations.
Solution Approach 2:
The system combines the cutting tool actuation and the working plate rotation into a coordinated automated process controlled by a single controller. The controller synchronizes the first motor (rotating the plate) and the second motor (actuating the cutting tool), merging multiple functions into a unified control system that improves precision while managing complexity through integrated control.
4Manufacturing precision
If automated systems with sensors and controllers are used, then the manufacturing precision and reliability are improved, but the use of energy increases due to multiple motors and electronic control components
Solution Approach 1:
The system performs cutting operations continuously as the working plate rotates, eliminating the need for repeated positioning and adjustment operations. The first motor continuously rotates the plate while the cutting tool operates, maintaining continuous useful action that improves efficiency and reduces energy consumption compared to intermittent manual operations.
