Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the grass trimmer uses a fixed integrated structure, then the structural strength and stability are improved, but the ease of disassembly and maintenance deteriorates
Solution Approach 1:
The grass trimmer is divided into multiple detachable modules including the machine head assembly, base assembly, trimming wheel device, and tank wheel device. Each module can be independently removed and reattached, allowing easy disassembly for maintenance while maintaining structural integrity during use through secure connection mechanisms.
2Reliability
If the grass trimmer uses a fixed structure, then the reliability is improved, but the adaptability to different scenarios deteriorates
Solution Approach 1:
The grass trimmer employs a dynamic reconfigurable structure where the machine head assembly can be detached and reattached to perform different functions. The trimming wheel device and tank wheel device can be selectively engaged based on operational requirements, enabling the system to adapt between trimming operations and having operations while maintaining reliable connections during each specific task.
3Stability of the object's composition
If the grass trimmer uses an integrated design, then the structural stability is improved, but the ease of cleaning and maintenance deteriorates
Solution Approach 1:
The integrated design is segmented into removable modules including the machine head assembly, base assembly, and wheel devices. This segmentation allows each component to be easily accessed, removed, cleaned, and maintained independently while maintaining structural stability when assembled, as each module connects to the base through secure attachment mechanisms.
4Adaptability or versatility
If the grass trimmer uses a complete integrated structure, then the functional completeness is improved, but the storage space requirement and transportation cost increase
Solution Approach 1:
The grass trimmer is segmented into modular components that can be detached from the base and stored separately when not in use. The machine head assembly, trimming wheel device, and tank wheel device can be removed and stored in compact spaces, significantly reducing storage requirements and transportation costs while maintaining full functional completeness when needed.

AI summary
This invention provides a grass trimmer and a method of using the same. The grass trimmer comprises a machine head including at least one electric motor, a grass trimmer head driven by the electric motor, and a housing for containing the electric motor. And a base including a shell. In addition, there is a trimming wheel device and a tank wheel device which assist in moving the grass trimmer head. The tank wheel device and the trimming wheel device form a detachable connection to the base. When trimming is required, the base connects to the trimming wheel device. When mowing is required, the tank wheel device replaces the connection between the trimming wheel device and the base.
