Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed support elements are used in advancement members, then the structure is simple, but the setup time is long and adaptability is poor
Solution Approach 1:
The support elements are designed to be adjustable in height along the vertical direction, transforming a static fixed structure into a dynamic adjustable one. This allows the advancement member to adapt to different fiber types, oven lengths, and temperature conditions while maintaining a relatively simple overall structure.
Solution Approach 2:
The adjustable support elements enable a single advancement member design to serve multiple functions: accommodating different fiber materials (PAN, pitch-based), different oven configurations, and various production requirements. This universal design reduces the need for multiple specialized fixtures.
2Adaptability or versatility
If complex adjustment mechanisms are added to advancement members, then adaptability improves, but the setup time increases
Solution Approach 1:
The support elements incorporate adjustable mechanisms that allow quick height modifications during operation. This dynamic adjustment capability enables operators to adapt the advancement member to different production conditions without time-consuming reconfiguration or complete disassembly.
3Manufacturing precision
If fixed roller positions are used, then the structure is simple, but fibre alignment and friction control are poor
Solution Approach 1:
The rollers are mounted on adjustable support elements that can be positioned vertically to optimize fiber alignment. This dynamic positioning capability ensures proper fiber tension and alignment while minimizing friction and slipping, achieving high manufacturing precision without excessive structural complexity.
4Ease of operation
If adjustable support elements are used, then adaptability and ease of operation improve, but device complexity increases
Solution Approach 1:
The support elements are designed with adjustment mechanisms that enable operators to easily modify the height of rollers and feed paths during operation. This dynamic adjustability significantly improves ease of operation, allowing quick adaptation to different fiber materials and production conditions while maintaining a manageable level of structural complexity.
