Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a conventional axle housing and pad mounting structure are used, then the drive apparatus can be mounted to the vehicle frame, but the structure becomes cumbersome and occupies large space
Solution Approach 1:
The patent removes the traditional axle housing and pad mounting structures from the drive apparatus. The planetary reduction units are directly mounted to the vehicle frame without requiring intermediate mounting structures, thereby eliminating unnecessary components and reducing overall volume while maintaining mounting functionality
Solution Approach 2:
The patent integrates the mounting function directly into the planetary reduction units themselves. The units are designed with direct mounting capabilities to the vehicle frame, combining what were previously separate functions (reduction gearing and mounting structure) into a single integrated component
2Weight of moving object
If a conventional axle housing is used, then power train components can be accommodated, but the drive apparatus becomes heavy and cannot realize lightweight
Solution Approach 1:
The patent divides the drive apparatus into separate planetary reduction units that can be independently configured. Each unit can be selectively applied based on specific application requirements, allowing for weight optimization by including only the necessary reduction stages rather than a fixed heavy axle housing structure
Solution Approach 2:
The patent enables flexible configuration of the drive apparatus where planetary reduction units can be added or removed based on application needs. This dynamic adaptability allows the system to be lightweight for applications requiring less reduction while maintaining the capability for heavier configurations when needed
3Area of stationary object
If a conventional pad mounting structure is used, then the drive apparatus can be mounted to the vehicle frame, but the mounting structure becomes cumbersome and occupies large space at the sides
Solution Approach 1:
The patent completely removes the pad mounting structures from both the drive apparatus and vehicle frame. The planetary reduction units are designed with direct mounting interfaces that eliminate the need for separate pad mounting structures, thereby reducing the area occupied at the sides of the vehicle frame while simplifying the mounting process
4Adaptability or versatility
If a conventional drive apparatus with fixed reduction ratio is used, then the structure is simple, but the reduction ratio cannot be adjusted conveniently
Solution Approach 1:
The patent divides the reduction system into separate planetary reduction units with different reduction ratios. By selectively combining these modular units, different overall reduction ratios can be achieved without requiring a completely different system design, maintaining relative structural simplicity while enabling adjustability
Solution Approach 2:
The patent creates a dynamically configurable reduction system where the number and arrangement of planetary reduction units can be adjusted based on the required reduction ratio. This allows the system to adapt to different application requirements while maintaining a relatively simple base structure
