Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a solar charger is installed in the bicycle basket for wireless charging, then mobile phone charging function is provided, but the device requires rain cover installation and sealing measures are needed to prevent water ingress

Engineering Contradiction:
Improvewireless charging functionVSAvoidsealing structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent integrates the wireless charging module directly into the bicycle frame structure, merging the charging function with the frame itself rather than using a separate basket-mounted solar charger. This integration eliminates the need for separate sealing measures and rain covers, as the charging components are built-in and protected by the frame's inherent structure.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent introduces a dedicated accommodating hole in the bicycle frame that serves as an intermediary structure to house the wireless charging module. This built-in accommodation space provides natural protection and positioning for the charging components, eliminating the need for external sealing structures while maintaining wireless charging functionality.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If cable-based charging is used for mobile phones during bicycle riding, then charging function is provided, but the user must interrupt journey to locate charging stations or carry supplementary power banks

Engineering Contradiction:
Improvecharging convenienceVSAvoidtime lost for charging interruptions
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent enables the bicycle itself to serve as the charging source through an integrated wireless charging module powered by the bicycle's power supply system. Users simply place their mobile phones on the designated area of the bicycle frame, and charging occurs automatically without requiring users to carry power banks or interrupt their journey to find charging stations.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces cable-based mechanical charging with wireless electromagnetic charging. The wireless charging module uses electromagnetic fields to transfer power to mobile phones, eliminating the need for physical cable connections and making the charging process more convenient during bicycle riding.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Adaptability or versatility

If existing wireless chargers without sealing structures are used, then wireless charging function is provided, but mobile phones are at risk of water ingress during rainy conditions

Engineering Contradiction:
Improvewireless charging functionVSAvoidwaterproof protection
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent merges the wireless charging module with the bicycle frame structure, creating an integrated system where the frame itself provides protection. This integration ensures that the charging components are naturally shielded from environmental elements including rain, eliminating water ingress risks without requiring separate sealing structures.

Inventive Principle:
Principle #5Merging (Combining)
