3Adaptability or versatility

If a complicated mounting system with many parts is used, then it can work for different types of bicycles, but it reduces locking reliability during frequent use

Engineering Contradiction:

Improvecompatibility with different bicycle typesVSAvoidlocking reliability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The locking device incorporates a spring-loaded rail member that automatically engages with the hook members when the pannier is attached. The spring provides continuous locking pressure, and the system self-adjusts to maintain secure engagement without requiring manual intervention or complex adjustment mechanisms, thereby improving reliability.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent extracts the essential locking function from a complex multi-part system and implements it through a simplified mechanism with fewer moving parts. By removing unnecessary components and focusing on the core locking action, the design reduces potential failure points while maintaining adaptability through careful geometric design of the hook and rail interfaces.

Inventive Principle:

Principle #2Taking out (Extraction)

4Device complexity

If a simple locking mechanism is used, then it reduces device complexity and cost, but it may not provide reliable locking during vibrations

Engineering Contradiction:

Improvenumber of partsVSAvoidlocking reliability under vibration

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The locking device incorporates a spring-loaded rail member that automatically engages with the hook members when the pannier is attached. The spring provides continuous locking pressure, and the system self-adjusts to maintain secure engagement without requiring manual intervention or complex adjustment mechanisms, thereby improving reliability.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The hook members and rail member are designed with curved surfaces that facilitate smooth engagement and maintain contact under vibrational loads. The curved geometry allows the components to self-center and maintain secure engagement even when subjected to vibrations, without requiring additional complex retention mechanisms.

Inventive Principle:

Principle #14Spheroidality (Curvature)
