Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sintered components (L-shaped members, U-shaped members) are used in the tension adjustment device, then the conveyor belt tension can be adjusted, but the manufacturing cost increases due to additional sintering molds
Solution Approach 1:
The patent replaces expensive sintered components with simple metal plates and adjustment bolts that are cheaper to manufacture. The metal plate with through-holes and adjustment bolts can be produced through conventional machining without requiring costly sintering molds, thereby reducing manufacturing costs while maintaining the tension adjustment function.
Solution Approach 2:
The patent changes the material and structural parameters of the tension adjustment device from sintered components to metal plates with through-holes. This parameter change allows the use of conventional manufacturing processes instead of sintering, reducing the need for specialized molds and lowering overall manufacturing costs.
2Device complexity
If sintered components are used in the tension adjustment device, then the structure can be compact, but the manufacturing complexity increases due to multiple sintering molds
Solution Approach 1:
The patent divides the tension adjustment device into separate functional components: a metal plate with through-holes for positioning, adjustment bolts for tension control, and a conveyor belt. This segmentation allows each component to be manufactured independently using simple processes, avoiding the need for complex sintering molds while maintaining structural compactness.
Solution Approach 2:
The patent replaces complex sintered components with simple, easily manufactured metal plates and bolts. These components can be produced through conventional machining processes without requiring specialized sintering molds, thereby reducing manufacturing process complexity while maintaining the required structural integrity.
3Reliability
If conventional tension adjustment devices are used, then the conveyor belt tension can be maintained, but friction and misalignment may cause damage to the conveyor belt
Solution Approach 1:
The patent extracts the harmful friction interface between sintered components and the conveyor belt by replacing them with metal plates and adjustment bolts. The new design minimizes contact friction and improves alignment, thereby reducing damage to the conveyor belt while maintaining tension maintenance capability.
Solution Approach 2:
The patent replaces friction-prone sintered components with simpler metal plates and adjustment bolts that have smoother surfaces and better alignment characteristics. This substitution reduces friction and misalignment issues, preventing damage to the conveyor belt while maintaining the tension adjustment function.

AI summary
A conveyor platform structure includes a platform having a first coupling portion and a second coupling portion respectively disposed on its two side edges adjacent to the front side and the rear side thereof. A driven shaft assembly is pivotally connected to one end of two adjustable extension units, while the other ends of the two adjustable extension units are connected to the first coupling portion of the platform. A driving shaft assembly is pivotally connected to one end of two fixed extension plates, while the other ends of the two fixed extension plates are connected to the second coupling portion of the platform. A conveyor belt is installed between the driven shaft assembly and the driving shaft assembly. The components of the adjustable extension units are simplified to achieve the effect of reducing manufacturing costs.
