Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a pulley mechanism is used for transmission, then the structure is simple, but the transmission efficiency is low and energy is wasted
Solution Approach 1:
The patent replaces the traditional pulley belt transmission system with a planetary gear reduction system. This substitution eliminates the energy loss associated with belt friction and slipping, providing high-efficiency mechanical power transmission while maintaining structural simplicity through the compact planetary gear design.
Solution Approach 2:
The patent changes the transmission mechanism from friction-based belt transmission to tooth-based gear transmission. This parameter change in the transmission principle fundamentally improves energy efficiency by eliminating slip and friction losses, while the planetary gear configuration maintains compact dimensions.
2Volume of moving object
If a conventional transmission system is used, then the structure is straightforward, but the size is large and flexibility is reduced
Solution Approach 1:
The patent employs a planetary gear system where planetary gears are nested around the sun gear within the planetary carrier. This nested configuration allows multiple gear elements to occupy a compact space, significantly reducing the overall transmission system size while maintaining high transmission efficiency and flexibility.
Solution Approach 2:
The patent merges the motor and planetary reducer into an integrated drive unit. This combination eliminates the need for separate coupling components and reduces the overall size of the transmission system, while the compact design enhances the flexibility and maneuverability of the snow plow.
3Device complexity
If the number of parts is reduced, then the device is simpler, but assembly and disassembly become more difficult
Solution Approach 1:
The patent segments the planetary reducer into distinct modular components: the planetary carrier assembly, the sun gear, the planetary gears, and the ring gear. This segmentation allows each component to be manufactured and assembled separately, then easily combined into the complete transmission system, facilitating both manufacturing and maintenance.
