Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the line is partially spiral-shaped with changing bending direction, then connections can be arranged on the outer edge, but bending the line requires considerable effort and significant installation space is lost
Solution Approach 1:
The line is divided into multiple straight sections connected by angular bends at fixed angles (e.g., 90 degrees). This segmentation allows the line to reach outer edge connections without requiring continuous or complex bending, as each section remains straight and is positioned through angular transitions rather than gradual curvature.
Solution Approach 2:
The line routing transitions from a two-dimensional planar spiral to a three-dimensional angular path with discrete directional changes. By using angular bends in multiple directions rather than continuous curvature, the line achieves outer edge connectivity while maintaining straight sections that reduce bending complexity and space requirements.
