Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If electrodes are sleeved on the coating film with interference fit, then the assembly process is simple, but the electrical connection becomes unreliable and electrodes may fall off
Solution Approach 1:
The electrode and base are merged into an integral structure through embedding, eliminating the separate assembly step of sleeving electrodes on coating films. The electrode is directly formed within the base material, ensuring permanent electrical connection without risk of detachment.
Solution Approach 2:
The coating film serves as an intermediary layer between the electrode and the external environment. The electrode is embedded within the base and connected to the coating film, which then interfaces with the heating element, providing stable electrical connection while protecting the electrode.
2Reliability
If electrodes are embedded in the base as integral structure, then electrical connection reliability is improved, but the manufacturing process becomes more complex
Solution Approach 1:
The electrode and base are combined into a single integral structure through embedding during the base manufacturing process. This merging eliminates the need for separate electrode assembly steps and reduces the number of discrete components, thereby simplifying the overall device structure despite the specialized manufacturing technique.
3Reliability
If the infrared radiation layer covers the electrode, then electrical connection is ensured, but the risk of coating film scraping off during assembly increases
Solution Approach 1:
The electrode is preliminarily embedded within the base structure before the coating film is applied. This preliminary positioning ensures the electrode is securely held in place and protected from scraping or detachment during subsequent assembly operations, while maintaining reliable electrical connection through the coating film.
