Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual freehand guidance of cutting tool is used, then ease of operation is improved, but manufacturing precision deteriorates
Solution Approach 1:
A guide device with a control cam serves as an intermediary between the operator and the cutting tool. The control cam's semi-parabolic profile guides the tool holder along a predetermined path, eliminating the need for skilled freehand guidance while maintaining operational simplicity. The guide device translates simple rotational motion into precise linear cutting paths.
Solution Approach 2:
The patent replaces the mechanical skill-based freehand guidance system with a mechanical guidance system based on a control cam. The cam's physical profile substitutes for the operator's manual control skills, providing automatic path control that ensures consistent semi-parabolic cable terminations without requiring operator expertise.
2Productivity
If motor-driven cutting tools are used, then productivity is improved, but manufacturing precision deteriorates
Solution Approach 1:
The guide device acts as an intermediary that couples the motor-driven cutting tool with precise path control. The control cam mediates between the motor's power and the cutting tool's motion, ensuring that high-speed machining produces precise semi-parabolic profiles rather than irregular shapes.
Solution Approach 2:
The guide device introduces dynamic control to the motor-driven system. The control cam's profile dynamically adjusts the tool holder's position along the cable axis during rotation, enabling the high-speed motor to produce precise, consistent cable terminations with varying distances from the cable surface during the cutting cycle.
3Device complexity
If freehand cutting is used, then device complexity is reduced, but shape consistency deteriorates
Solution Approach 1:
The control cam serves as a simple intermediary component that embodies the desired semi-parabolic shape. By incorporating the shape profile directly into the cam's physical form, the device achieves consistent cable termination shapes without complex control systems, computers, or sensors.
Solution Approach 2:
The control cam's profile is pre-formed to match the desired semi-parabolic cable termination shape. This preliminary action of shaping the cam ensures that every cutting operation automatically produces the correct shape, eliminating variability without requiring complex real-time control or adjustment mechanisms.
