Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If cylindrical heating members with electrodes at opposite ends are used, then heating function is achieved, but assembly complexity increases due to electrode leads occupying space and requiring liquid conducting material to evade lead positions
Solution Approach 1:
The heating member is segmented into multiple heating sections (first heating section, second heating section, third heating section) with electrode leads concentrated at one end. This segmentation allows the liquid conducting material to be wrapped continuously without evading multiple lead positions, simplifying assembly while maintaining heating functionality across different zones.
2Ease of operation
If C-shaped tubular heating members are used, then assembly is simplified, but radial support is insufficient causing deformation and poor contact with liquid conducting material
Solution Approach 1:
The heating member is designed as a complete circular tubular structure rather than a C-shape, providing full 360-degree radial support. This circular configuration maintains structural strength while ensuring uniform contact with the liquid conducting material wrapped around it, preventing deformation during operation.
3Reliability
If current cylindrical heating members are used, then heating is achieved, but heating value is not easy to adjust and size changes during production affect consistency
Solution Approach 1:
The heating member is divided into multiple independent heating sections with distinct resistance values (first heating section with higher resistance, second and third sections with lower resistance). This segmentation enables adjustable overall heating value by controlling which sections are activated, while the modular design ensures consistent performance despite production variations.
4Ease of operation
If electrodes are led out through the same end, then connection is simplified, but leads occupy space and make liquid conducting material wrapping difficult
Solution Approach 1:
Multiple electrode leads are merged and concentrated at one end of the heating member rather than being distributed along its length. This consolidation simplifies electrical connection while creating a compact lead arrangement that allows liquid conducting material to be wrapped continuously around the heating member without needing to evade multiple lead positions.
