Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a cable-based charger is used for mobile phone charging during bicycle rides, then charging function is provided, but convenience deteriorates due to cable management and interruption of journey to locate charging stations
Solution Approach 1:
The patent replaces the mechanical cable-based charging system with a wireless charging system. The wireless charging module uses electromagnetic induction to transfer power without physical contact, eliminating the need for cable plugging and unplugging. This allows users to charge their phones continuously during rides without interrupting their journey to locate charging stations or manage cables.
2Ease of operation
If the wireless charger is installed on the handlebar without sealing structure, then wireless charging function is provided, but reliability deteriorates due to water ingress risk during rainy days
Solution Approach 1:
The patent employs a sealing cover made of flexible waterproof material that completely encloses the wireless charging module. This flexible shell structure provides effective waterproof protection while allowing the wireless charging function to operate normally. The sealing cover prevents water ingress during rainy days, ensuring reliable operation of the wireless charging system in various weather conditions.
3Adaptability or versatility
If the solar charger is installed in the bicycle basket, then wireless charging function is provided, but device complexity increases due to need for rain cover and sealing structures
Solution Approach 1:
The patent merges the wireless charging module directly into the bicycle frame structure, specifically integrating it into the seat tube. This integration eliminates the need for separate sealing structures and rain covers that would be required if the charger were installed in the bicycle basket. The unified design reduces overall device complexity while maintaining waterproof performance and wireless charging functionality.
4Reliability
If a sealed accommodating box is used for wireless charging module, then waterproof performance is improved, but ease of operation deteriorates due to difficulty in accessing and maintaining the module
Solution Approach 1:
The patent segments the sealed accommodating box into two parts: a fixed sealed housing that maintains waterproof integrity, and a removable sealing cover that provides access to the wireless charging module. This segmentation allows the module to be easily accessed for maintenance or replacement by simply removing the sealing cover, while the main sealed housing continues to provide waterproof protection. This design resolves the contradiction between waterproof performance and ease of maintenance.
