Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If a traditional bicycle design is used, then the structure is simple, but aerodynamic drag is high and rider comfort is insufficient

Engineering Contradiction:
Improveaerodynamic dragVSAvoiddevice structure
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The device is divided into multiple functional components: a support plate attached to handlebars, brackets for mounting, a frame with forearm support surface, adjustable joints, and cable housings. Each segment performs a specific function, allowing the system to reduce aerodynamic drag while maintaining manageability through modular construction.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The device incorporates adjustable joints that allow dynamic repositioning of the forearm support frame relative to the handlebars. This dynamic adjustment capability enables riders to optimize their aerodynamic position based on riding conditions while maintaining comfort, resolving the contradiction between drag reduction and structural simplicity.

Inventive Principle:
Principle #15Dynamics

2Object-affected harmful factors

If an aerodynamic position is adopted, then aerodynamic drag is reduced, but rider stability and comfort deteriorate

Engineering Contradiction:
Improveaerodynamic dragVSAvoidrider stability
Core Design Contradiction:
Object-affected harmful factorsVSStability of the object's composition

Solution Approach 1:

The adjustable joint mechanism allows riders to dynamically modify their riding position and aerodynamic profile while maintaining stability. The frame provides a stable base for forearm support, and the adjustable connections enable position optimization without compromising rider security or balance.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The device enables parameter changes in rider position through adjustable joints and movable components. Riders can modify the angle and position of the forearm support frame to achieve optimal aerodynamics while maintaining comfort and stability, directly addressing the contradiction between drag reduction and stability.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If electronic devices are integrated into the bicycle, then functionality is improved, but device complexity and cable management issues increase

Engineering Contradiction:
Improveelectronic device integrationVSAvoidcable management
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The device integrates multiple functions into a unified structure: the support frame, cable housings, and mounting brackets work together as a cohesive system. This merging of functions reduces overall complexity compared to separate installations, while providing structured cable management and electronic device mounting capabilities.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The device introduces intermediary elements such as cable housings and structured mounting points that facilitate clean cable management. These intermediaries organize and protect cables running to electronic devices, reducing complexity and improving aesthetics without limiting functionality.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Adaptability or versatility

If adjustable joints are added for flexibility, then adaptability is improved, but device complexity increases

Engineering Contradiction:
Improveposition adjustabilityVSAvoidjoint mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The device employs adjustable joints that provide dynamic positioning capability while maintaining structural integrity. These joints allow the forearm support frame to be repositioned relative to the handlebars, offering adaptability for different rider preferences and riding conditions without requiring an overly complex mechanism.

Inventive Principle:
Principle #15Dynamics
