VSEngineering Contradiction Analysis

1Adaptability or versatility

If add-on bicycle carriers are used to transport bicycles, then bicycle transportation capability is provided, but aerodynamic efficiency deteriorates due to increased drag

Engineering Contradiction:
Improvebicycle transportation capabilityVSAvoidaerodynamic drag
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The frame clamp integrates the clamping mechanism and positioning elements into a unified structure that attaches to the vehicle's existing aerodynamic contours. The jaws, resilient inserts, and locating rod are combined into a single integrated component that maintains the vehicle's streamlined shape while providing bicycle transport capability.

Inventive Principle:

2Ease of manufacture

If fixed clamp distance is used in frame clamp, then manufacturing simplicity is improved, but adaptability deteriorates as different bicycle sizes cannot be accommodated

Engineering Contradiction:
Improveclamp manufacturing simplicityVSAvoidbicycle size accommodation
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The frame clamp employs an adjustable connection mechanism with multiple apertures and a pivot bolt that allows the clamp distance to be dynamically changed. This enables the same clamp structure to accommodate various bicycle frame sizes while maintaining a simple manufacturing process using standard adjustable fastening components.

Inventive Principle:
