Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple attachment method is used for the current collecting pad to the feeding pad, then the device complexity is reduced, but the alignment precision between the pads deteriorates
Solution Approach 1:
The patent introduces a wheel guide as an intermediary component between the feeding pad and the current collecting pad. The wheel guide includes guiding surfaces that passively guide the wheel into correct alignment, ensuring precise pad alignment without requiring complex active adjustment mechanisms. This resolves the contradiction by providing accurate alignment through a simple passive guiding structure rather than complex active control.
2Adaptability or versatility
If structures of handle frames and wheels are made different for each manufacturer, then the adaptability to various personal mobilities is improved, but the alignment precision between pads deteriorates
Solution Approach 1:
The wheel guide acts as a universal intermediary that accommodates different wheel structures from various manufacturers. The guiding surfaces are designed to work with standard wheel dimensions while maintaining consistent alignment, allowing the system to adapt to different personal mobility devices without sacrificing alignment precision.
Solution Approach 2:
The wheel guide is designed with adjustable or variable parameters in its guiding surfaces that can accommodate different wheel sizes and handle frame configurations. By changing the geometric parameters of the guiding surfaces rather than the entire alignment mechanism, the system maintains precision across different device types.
3Ease of operation
If no means for making handle angle constant is provided, then the ease of operation is improved, but the alignment precision between pads deteriorates
Solution Approach 1:
The wheel guide serves as a passive intermediary that automatically establishes the correct handle angle and pad alignment through its guiding surfaces. The user simply needs to dock the wheel, and the guiding surfaces automatically orient the handle frame and align the pads, maintaining precision without requiring the user to control the handle angle.
Solution Approach 2:
The alignment system performs self-service by using the wheel's own insertion into the guiding surfaces to automatically establish correct alignment. The geometry of the wheel guide and wheel interaction automatically sets the handle angle and pad positioning, eliminating the need for active control mechanisms while maintaining precision.
4Ease of manufacture
If contact-type wired charging is used, then the ease of manufacture is improved, but the reliability of charging deteriorates
Solution Approach 1:
The patent replaces the mechanical contact-based wired charging system with a wireless charging system. This substitution eliminates the reliability issues associated with physical contact (poor contact, electric shock risk, short circuit) while maintaining ease of manufacture through the use of standard wireless charging components and the passive wheel guide alignment mechanism.
