Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional conveyor systems use belts and gears to drive rollers, then the structure is simpler and easier to manufacture, but dust is generated due to friction between belts and gears
Solution Approach 1:
The patent extracts and eliminates the belts and gears from the conveyor system, replacing them with a direct drive mechanism where motors are mounted directly on the rollers. This removal of intermediate transmission components eliminates the friction and dust generation problem while maintaining the driving function.
Solution Approach 2:
The patent replaces the traditional mechanical transmission system (belts and gears) with a direct motor-roller connection system. This substitution eliminates the need for intermediate mechanical components that generate friction and dust, achieving a cleaner conveying environment.
2Object-affected harmful factors
If each driving roller is driven by a respective motor, then dust generation is reduced by eliminating sliding friction and gear meshing, but the device complexity increases due to multiple motors and controllers
Solution Approach 1:
The patent segments the driving system into independent motor-roller units, with each roller having its own motor. This segmentation allows for simplified control and maintenance while eliminating the complex belt-gear transmission system that causes dust generation.
3Ease of operation
If multiple motors are controlled by separate motor controllers, then each motor can be independently controlled for precise operation, but the cost increases due to multiple controllers
Solution Approach 1:
The patent merges the control function by enabling multiple motors to be controlled by a single motor controller through shared control lines. This consolidation reduces the number of controllers needed while maintaining the ability to independently control each motor's rotation, thereby reducing cost without sacrificing operational precision.
