Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If physical fastening means are used to connect accessories to the device, then the connection strength is improved, but the device complexity and ease of operation deteriorate
Solution Approach 1:
The patent replaces mechanical fastening systems (screws, clips, latches) with a magnetic coupling system. The magnetic accessory attaches to the self-propelled device through magnetic attraction forces, eliminating the need for complex mechanical fastening mechanisms while maintaining secure connection strength.
Solution Approach 2:
The patent introduces a magnetic field as an intermediary between the accessory and the device. This magnetic field serves as the coupling mechanism, allowing accessories to attach and detach easily without direct mechanical contact or complex fastening structures.
2Strength
If physical fastening means are used to connect accessories to the device, then the connection strength is improved, but the ease of operation deteriorates
Solution Approach 1:
The patent replaces mechanical fastening systems (screws, clips, latches) with a magnetic coupling system. The magnetic accessory attaches to the self-propelled device through magnetic attraction forces, eliminating the need for complex mechanical fastening mechanisms while maintaining secure connection strength.
Solution Approach 2:
The magnetic coupling system allows accessories to self-align and self-attach to the device through magnetic attraction. The magnetic force automatically guides the accessory into the correct position and secures it without requiring manual alignment or operation of fastening mechanisms.
3Measurement precision
If specialized remote controllers are used to operate remote controlled devices, then the control precision is improved, but the adaptability deteriorates
Solution Approach 1:
The patent makes the self-propelled device universally controllable through multiple interfaces. The device can be operated through magnetic coupling with various accessories including mobile devices, computers, and other control systems, eliminating the need for specialized remote controllers and enabling the device to adapt to different user preferences and scenarios.
