Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the front upright is fixedly connected to the bicycle frame, then the structure is simple and stable, but the angle cannot be adjusted and cannot accommodate users of different heights and arm lengths

Engineering Contradiction:

Improveadjustability of front upright angleVSAvoidcomplexity of connection structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The front upright connection is transformed from a fixed static structure to a dynamic adjustable structure. The bracket component can rotate around the rotary shaft to change the angle of the front upright, allowing adaptation to different user needs while maintaining structural stability through the supporting component and positioning mechanism.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The connection structure is divided into separate functional components: a supporting component fixed to the frame, a bracket component attached to the front upright, and a rotary shaft connecting them. This segmentation allows independent optimization of each component and enables angle adjustment while maintaining overall structural integrity.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If a rotary shaft and bracket component are introduced for angle adjustment, then the front upright becomes adjustable for different users, but the structure becomes more complex

Engineering Contradiction:

Improveadjustability of front upright angleVSAvoidstability of connection

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The bracket component is pre-equipped with positioning grooves or positioning holes that align with corresponding features on the supporting component. This preliminary arrangement ensures that when the bracket rotates to different angles, it automatically engages with the positioning features, providing stable and reliable connection without requiring additional locking mechanisms.

Inventive Principle:

Principle #10Preliminary action

3Reliability

If positioning tooth grooves or holes are used for angle locking, then the front upright can be securely fixed at different angles, but the manufacturing precision requirements increase

Engineering Contradiction:

Improvelocking reliability at different anglesVSAvoidprecision of positioning features

Core Design Contradiction:

ReliabilityVSManufacturing precision

Solution Approach 1:

The positioning mechanism is designed to be self-aligning and self-locking. The positioning grooves or holes on the bracket component naturally engage with the corresponding features on the supporting component through the rotation motion, automatically achieving accurate positioning without requiring high-precision manual adjustment or complex alignment procedures during manufacturing.

Inventive Principle:

Principle #25Self-service
