Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a guide rail slider with T-shaped groove is used for displacement, then the calibration member can be positioned at different locations, but the installation is inconvenient and costly due to high installation surface requirements

Engineering Contradiction:
Improvepositioning capabilityVSAvoidinstallation convenience
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The displacing assembly is divided into separate components: a displacing block with rolling mechanisms and a connecting portion. This segmentation allows each part to be manufactured and installed independently, reducing installation complexity and surface requirements while maintaining positioning functionality.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The traditional T-shaped groove mechanical connection is replaced with a rolling mechanism system. The rolling mechanisms engage with guide grooves on the guide rail, providing positioning and movement guidance without requiring complex mechanical interlocking, thereby simplifying installation.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If a guide rail slider with T-shaped groove is used for displacement, then the calibration member can be positioned at different locations, but the cost increases due to high installation requirements

Engineering Contradiction:
Improvepositioning capabilityVSAvoidinstallation cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The displacing assembly uses simple, easily manufactured components such as rolling blocks and guide grooves that can be produced at low cost. These components do not require expensive precision machining or specialized installation procedures, reducing overall system cost while maintaining positioning functionality.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

3Ease of operation

If a T-shaped groove is used for displacement, then the calibration member can move along the guide rail, but the weight capacity is limited and friction is excessive

Engineering Contradiction:
Improvedisplacement smoothnessVSAvoidload capacity
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The sliding friction mechanism of the T-shaped groove is replaced with a rolling contact mechanism. The rolling mechanisms reduce friction between the displacing assembly and guide rail, enabling smooth movement while the guide grooves provide structural support for heavy loads.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The rolling mechanisms incorporate curved or rounded contact surfaces that engage with the guide grooves. This curvature allows for rolling motion rather than sliding, reducing friction and enabling smooth displacement while maintaining load-bearing capacity.

Inventive Principle:
Principle #14Spheroidality (Curvature)

4Adaptability or versatility

If a T-shaped groove is used for displacement, then the calibration member can be positioned, but the displacement is unsmooth due to excessive friction

Engineering Contradiction:
Improvepositioning capabilityVSAvoiddisplacement smoothness
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The sliding friction mechanism is replaced with rolling contact. The rolling mechanisms rotate along the guide grooves, converting sliding friction into rolling friction, which is significantly lower and enables smooth, controlled displacement of the calibration member.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
