Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If external power supply is used, then device can operate continuously, but structure becomes complex and installation becomes inconvenient
Solution Approach 1:
The patent extracts and eliminates the external power supply and charging components from the wheel display device, replacing them with a self-powered generation system that converts wheel rotation directly into electrical energy, thereby simplifying the overall structure while maintaining continuous operation capability
Solution Approach 2:
The device generates its own power through the self-powered unit that converts mechanical energy from wheel rotation into electrical energy, making the system self-sufficient and eliminating the need for external power sources, charging ports, and battery management infrastructure
2Adaptability or versatility
If display content is stored internally, then device is self-contained, but replacement of display content becomes complicated
Solution Approach 1:
The control circuit board is designed with universal communication interfaces that can receive and process various types of display content through wireless transmission, enabling the device to function with multiple content sources without requiring physical content storage or complex replacement mechanisms
Solution Approach 2:
The patent replaces physical content storage and mechanical content replacement with wireless digital transmission, allowing content to be updated remotely and instantly without physical access to the device or complex internal storage management
3Reliability
If motion state parameters are not acquired in real time, then device structure is simpler, but display stability and clarity deteriorate
Solution Approach 1:
The patent implements real-time feedback loops where sensors continuously monitor wheel rotation parameters and feed this data to the control circuit, which dynamically adjusts LED brightness, timing, and positioning to maintain optimal display quality under varying rotational conditions
Solution Approach 2:
The control circuit board serves multiple functions simultaneously: it controls LED display output, processes sensor data from multiple sensors, performs real-time coordinate transformations, and adjusts display parameters dynamically, consolidating these functions into a single integrated unit rather than separate components
