Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If tabs are folded and bent to fix tubular heaters and solder wires, then the tubular heaters can be secured to the carrier plate, but the production process becomes labor-intensive and time-consuming
Solution Approach 1:
The patent changes the geometric parameter of the carrier plate by reducing its thickness in specific regions to form receptacles. This parameter change eliminates the need for folding tabs, allowing tubular heaters to be simply inserted into the receptacles, thereby significantly improving production speed while maintaining secure fixation.
2Manufacturing precision
If tabs are folded and bent to fix tubular heaters, then the heaters can be positioned, but additional tools are required and production costs increase
Solution Approach 1:
The patent extracts the tabs from the carrier plate structure by reducing the plate thickness in the receptacle regions. This extraction eliminates the need for additional tools to fold and bend tabs, simplifying the manufacturing process while maintaining precise positioning capability through the receptacle geometry.
3Ease of manufacture
If the carrier plate has uniform thickness, then the structure is simple to manufacture, but heat transfer from tubular heaters is hindered
Solution Approach 1:
The patent applies local quality by reducing the carrier plate thickness specifically in the receptacle regions where tubular heaters are positioned, while maintaining the original thickness in other areas. This localized thinning improves heat transfer efficiency at the heater contact points without compromising the overall structural integrity and manufacturing simplicity of the carrier plate.
