Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional conveyor belts are used, then basic transportation function is provided, but products stick to the belt and functionality deteriorates over time due to insufficient temperature resistance
Solution Approach 1:
The invention uses a core-sheath thread structure where the core provides mechanical strength and the sheath provides temperature resistance and anti-adhesive properties. This composite material approach combines the advantages of different materials to simultaneously achieve high temperature resistance (up to 260°C) and reliable functionality maintenance over time.
Solution Approach 2:
The invention changes the material parameters of the conveyor belt by using specific polymers (polyetherketone for the core and perfluoroalkoxy polymer for the sheath) that maintain their physical and chemical properties at high temperatures, thereby enabling the belt to resist temperature-induced degradation and sticking.
2Object-affected harmful factors
If conventional materials are used for conveyor belts, then basic structural requirements are met, but anti-adhesive properties are insufficient causing product sticking
Solution Approach 1:
The core-sheath thread structure combines materials with complementary properties: the polyetherketone core provides structural integrity while the perfluoroalkoxy polymer sheath provides superior anti-adhesive properties. This composite approach effectively prevents product sticking without requiring complex manufacturing processes, as the core-sheath structure can be produced using standard textile manufacturing techniques.
3Temperature
If high temperature resistant materials are used, then temperature resistance is improved, but the material may become too rigid or difficult to process
Solution Approach 1:
The core-sheath structure allows the polyetherketone core to provide temperature resistance while the perfluoroalkoxy polymer sheath maintains flexibility and processability. This division of functions enables the material to withstand high temperatures (up to 260°C) while remaining easy to manufacture and process using conventional textile methods.
Solution Approach 2:
Different parts of the thread have different properties optimized for their specific functions: the core is designed for thermal stability and strength, while the sheath is designed for flexibility, anti-adhesion, and ease of processing. This local optimization allows the overall material to achieve high temperature resistance without sacrificing processability.
