Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional suspension seatposts use a single elasticity coefficient design, then the structure is simple, but the adaptability to different riding conditions is poor

Engineering Contradiction:

Improveadaptability to different riding conditionsVSAvoidstructure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The elastic component is divided into multiple segments with different elasticity coefficients. Each segment can be independently selected and positioned within the linkage assembly, allowing the system to provide multiple suspension characteristics without requiring multiple complete seatpost assemblies. This segmentation enables adaptability to different riding conditions while keeping the overall structure relatively simple.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The seatpost design allows dynamic adjustment of the elasticity coefficient by enabling the user to reposition or replace different elastic segments within the linkage assembly. This dynamic configurability lets riders adapt the suspension characteristics to match varying terrain and riding styles, transforming a static single-coefficient design into a dynamic multi-coefficient system.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If the elasticity coefficient is adjusted by replacing the entire seatpost, then the elasticity coefficient can be changed, but the time consumption and operation complexity increase significantly

Engineering Contradiction:

Improveelasticity coefficient adjustment capabilityVSAvoidadjustment operation ease

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

By segmenting the elastic component into replaceable modules with different elasticity coefficients, the system allows users to adjust the suspension characteristics by swapping only the relevant elastic segment rather than the entire seatpost. This modular approach dramatically reduces adjustment time and operational complexity while maintaining full adaptability across different riding conditions.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different elastic segments are pre-configured with specific elasticity coefficients suitable for different riding conditions. Users can select and install the appropriate pre-configured segment before riding, eliminating the need for complex on-the-spot adjustments or professional intervention. This preliminary preparation enables quick and easy adaptation to varying terrain requirements.

Inventive Principle:

Principle #10Preliminary action

3Manufacturing precision

If professionals are required to adjust the elasticity coefficient, then the adjustment precision can be ensured, but the time consumption and operational complexity increase

Engineering Contradiction:

Improveelasticity coefficient adjustment precisionVSAvoidadjustment time

Core Design Contradiction:

Manufacturing precisionVSLoss of time

Solution Approach 1:

The elastic component is segmented into standardized modules with precisely engineered elasticity coefficients. Each segment is designed with consistent dimensions and material properties, ensuring that when users install a specific segment, the elasticity coefficient is accurately set without requiring professional calibration. This standardized segmentation maintains precision while enabling user-friendly adjustment.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system provides discrete elasticity coefficient values through different elastic segments, allowing users to select from predetermined parameter options. This approach ensures precise elasticity settings are achieved through simple selection and installation of the appropriate segment, eliminating the need for time-consuming professional adjustment procedures while maintaining accurate parameter control.
