Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a slide rail mechanism is designed with fixed height and angle, then the structure is simple and easy to manufacture, but it lacks adaptability to varying market demands and operational needs

Engineering Contradiction:
ImproveadaptabilityVSAvoidcomplexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies the dynamics principle by transforming the fixed slide rail structure into an adjustable one. The slide rail incorporates height adjustment mechanisms and angle adjustment mechanisms that allow the rail to change its position and orientation dynamically. This enables the slide rail to adapt to different furniture configurations and operational requirements while maintaining a relatively simple base structure.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements parameter changes by providing adjustable height parameters and angle parameters through the height adjustment mechanisms and angle adjustment mechanisms. These mechanisms allow users to modify the vertical position and inclination angle of the slide rail, thereby changing the operational parameters to suit different market demands and furniture designs.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If adjustment mechanisms are added to the slide rail, then height and angle adaptability improve, but the device complexity increases

Engineering Contradiction:
ImproveadjustabilityVSAvoidcomplexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies segmentation by dividing the adjustment functionality into distinct modular components: height adjustment mechanisms and angle adjustment mechanisms. Each mechanism is implemented as a separate adjustable element that can be independently controlled. This modular approach allows for adjustability while keeping individual mechanism complexity manageable and enabling easy maintenance or replacement.

Inventive Principle:
Principle #1Segmentation

3Manufacturing precision

If precise adjustment mechanisms are implemented, then alignment precision improves, but the ease of operation may deteriorate

Engineering Contradiction:
Improvealignment precisionVSAvoidease of operation
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The patent implements preliminary action by providing pre-adjusted reference positions and guide features in the adjustment mechanisms. The height adjustment and angle adjustment mechanisms are designed with predetermined adjustment steps or guide marks that help users achieve proper alignment without requiring complex measurements or calculations. This preliminary structuring maintains precision while improving operational ease.

Inventive Principle:
Principle #10Preliminary action
