Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If engine-powered mowers are used to increase mowing efficiency, then productivity is improved, but harmful factors (noise, air pollution, vibration) increase
Solution Approach 1:
The patent replaces the engine-powered mechanical system with an electric motor system. The mower uses an electric motor instead of an internal combustion engine, eliminating exhaust emissions and reducing noise and vibration. The electric motor is powered by a rechargeable battery that can be charged via solar panels or wireless charging, further reducing environmental impact while maintaining high mowing efficiency.
2Object-generated harmful factors
If manual mowing methods are used to reduce environmental impact, then harmful factors are reduced, but productivity decreases
Solution Approach 1:
The patent implements automatic mowing functionality where the mower can operate autonomously without continuous manual intervention. The mower includes sensors and control systems that enable it to navigate and mow automatically, reducing the labor burden on users while maintaining high productivity. This automatic operation allows the mower to work efficiently over large areas without requiring constant human oversight.
3Adaptability or versatility
If solar energy converting device and wireless receiving device are added to enable multiple charging methods, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent integrates multiple charging functions into a single energy storage system. The mower includes both solar panels for photovoltaic charging and a wireless receiving device for inductive charging, both feeding into the same rechargeable battery system. This multi-functional design allows the mower to be charged through multiple pathways (solar energy, wireless charging, or traditional electrical charging) without requiring separate power systems, thereby increasing adaptability while managing complexity through unified battery management.
