Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the accommodation body uses a traditional integrated structure, then the structural strength is sufficient, but the assembly and disassembly process becomes complex and time-consuming
Solution Approach 1:
The accommodation body is divided into multiple modular components: first accommodation part, second accommodation part, side cover board, and partial cover boards. These segments can be independently assembled and disassembled, significantly improving ease of manufacture and assembly while maintaining structural integrity through standardized connection interfaces.
2Measurement precision
If the turning control mechanism is simplified, then the device complexity is reduced, but the turning control precision deteriorates
Solution Approach 1:
The patent replaces traditional mechanical angle measurement mechanisms with electronic sensors and control systems. This substitution enables precise turning control through electronic detection and digital processing while avoiding the mechanical complexity of gear-based or linkage-based angle measurement systems.
3Ease of operation
If the scooter structure is compact and fixed, then the structural stability is high, but the parking convenience and space efficiency are reduced
Solution Approach 1:
The patent introduces adjustable and foldable components such as the handle assembly and support frame that can transition between fixed and folded positions. When folded, these components reduce the overall occupied space for convenient parking, while the modular design ensures structural stability is maintained through proper connection mechanisms during both extended and folded states.
