Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual labor is used to remove the outer insulating member and foil, then flexibility and adaptability are maintained, but working time increases and uniformity of removal is difficult to achieve
Solution Approach 1:
The removal device is segmented into distinct functional units: a cutting unit with rotating cutting blades for cutting the foil, and a stripping unit with stripping members for removing the cut foil. This segmentation allows each unit to perform its specific function efficiently, reducing overall working time while maintaining manageable device complexity through modular design
Solution Approach 2:
The cutting blades are configured to automatically cut the foil as the cable passes through, and the stripping members automatically strip the cut foil without requiring manual intervention. This self-service mechanism eliminates manual labor, significantly reducing working time while the automated process ensures uniform removal across different cables
2Manufacturing precision
If manual labor is used to remove the outer insulating member and foil, then device complexity is minimized, but uniformity of removal and consistency are difficult to achieve
Solution Approach 1:
The rotating cutting blades and stripping members operate in a controlled sequence, with the cutting unit first cutting the foil and then the stripping unit removing it. This sequential feedback mechanism ensures that each cable receives consistent treatment, achieving uniform removal. The rotational motion provides continuous contact and control, eliminating the variability inherent in manual operations
Solution Approach 2:
The cutting blades and stripping members are designed with specific geometric parameters and rotational speeds that optimize the cutting and stripping process. By controlling these parameters, the device achieves consistent and uniform foil removal across different cables, transforming the variable manual process into a controlled automated operation
3Speed
If a rotating disc-shaped cutter is used to strip coaxial cable, then stripping speed is improved, but the ability to handle different cable types and achieve precise control is reduced
Solution Approach 1:
The cutting blades and stripping members are designed to rotate rather than remain fixed, allowing them to adapt to different cable diameters and types. The rotational motion provides dynamic contact that can accommodate variations in cable geometry while maintaining high stripping speed. This dynamic design replaces the rigid disc-shaped cutter with a more versatile rotating mechanism
4Manufacturing precision
If cutting blades are fixed in position, then device simplicity is maintained, but the ability to adjust for different cable sizes and achieve precise cutting is limited
Solution Approach 1:
The cutting blades are made rotatable rather than fixed, allowing them to dynamically adjust to different cable sizes through rotational motion. This dynamic positioning enables precise cutting for various cable types without requiring complex adjustable mechanisms, as the rotation itself provides the necessary adaptation
