Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the polymerization belt is supported by conventional means, then the belt can maintain its position, but the belt experiences high tension and sagging which reduces service life
Solution Approach 1:
A support belt is introduced as an intermediary element between the polymerization belt and the stationary support structure. The support belt slides on stationary support surfaces, acting as a mediator that reduces the tension and sagging forces on the polymerization belt while maintaining proper positioning and support during the polymerization process.
2Manufacturing precision
If the polymerization belt is supported by conventional means, then the belt can maintain its position, but sagging occurs which affects polymerization quality
Solution Approach 1:
The support belt serves as a mediator that prevents direct contact between the polymerization belt and stationary supports, thereby minimizing sagging and maintaining the proper shape and tension of the polymerization belt for consistent polymerization quality.
Solution Approach 2:
The system changes the physical parameters of belt support by introducing a moving support belt that slides on stationary surfaces, altering the tension and position parameters of the polymerization belt to eliminate sagging and maintain manufacturing precision.
3Temperature
If a metallic support belt is used, then cooling efficiency is improved due to high heat transfer capacity, but the complexity of the system increases
Solution Approach 1:
The material parameter of the support belt is changed to metal, which has high thermal conductivity. This parameter change enables efficient heat transfer and cooling of the polymerization belt while the sliding mechanism on stationary supports keeps the overall system complexity manageable.
