Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If exposed wires are used to connect the display unit and remote switch, then electrical connection is achieved, but wind resistance and drag increase
Solution Approach 1:
The patent replaces the mechanical wire-based electrical connection system with a wireless radio frequency communication system. The remote switch and display unit communicate switching signals wirelessly through radio waves, eliminating the need for physical wires extending along the handlebar, thus reducing wind resistance and drag while maintaining electrical connection functionality
Solution Approach 2:
The patent extracts the communication functionality from the physical wire connection and implements it through a wireless radio frequency module integrated into the remote switch. This extraction removes the harmful exposed wires from the system while preserving the essential signal transmission function
2Productivity
If a remote switch is used to switch display data, then cycling continuity is improved, but wind resistance increases due to exposed wires
Solution Approach 1:
The patent substitutes the mechanical wire connection with wireless radio frequency communication, allowing the remote switch to transmit switching signals without exposed wires. This maintains cycling continuity by enabling remote operation while eliminating the drag caused by wire exposure
3Ease of operation
If hands are moved from handlebar grip to press display buttons, then display switching is achieved, but cycling performance deteriorates
Solution Approach 1:
The patent introduces a wireless communication module as an intermediary between the remote switch and display unit. This intermediary enables signal transmission without physical wire connections, allowing cyclists to operate the display unit with one hand on the grip while maintaining cycling performance
