Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a lead is welded to the heating element for connection, then contact resistance is low and resistance is stable, but poor welding occurs easily and manual assembly is required consuming large labor
Solution Approach 1:
The patent removes the lead component entirely from the connection system. Instead of welding a lead to the heating element, the heating element's own electrical connection part is directly exposed and contacted by the electrode, eliminating the intermediate lead component that caused welding issues and manual assembly requirements.
Solution Approach 2:
The heating element serves its own dual function: it both heats the liquid and provides the electrical connection interface. The electrical connection part of the heating element directly contacts the electrode without requiring external leads or complex welding processes, enabling automatic assembly.
2Ease of manufacture
If electrodes are in direct contact with contacts at the bottom of heating element, then assembly is simple, but contact resistance is large and contact is poor due to size accuracy issues and deformation
Solution Approach 1:
The patent changes the contact interface from a vertical bottom-contact configuration to a side-contact configuration. The electrode contacts the electrical connection part laterally rather than from below, moving the contact point to a different spatial dimension where dimensional tolerance and deformation have less impact on contact quality.
Solution Approach 2:
Instead of the electrode contacting the bottom of the heating element (conventional approach), the invention inverts the contact orientation so that the electrode contacts the side of the electrical connection part. This inversion allows for better dimensional tolerance and more stable electrical contact.
3Reliability
If electrical connection part is bent to connect with electrode, then connection reliability is improved and automatic assembly is enabled, but manufacturing complexity increases
Solution Approach 1:
The patent changes the geometric parameters of the electrical connection part by bending it into different configurations (first bending to side, or first bending to side then bending to bottom, or engaging into support). These parameter changes enable reliable contact and automatic assembly while keeping the overall structure relatively simple.
