Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a rack and pinion drive is used for width adjustment, then the spacer device can be adjusted for selected widths, but the design becomes complex and manufacturing becomes difficult

Engineering Contradiction:
Improvewidth adjustment capabilityVSAvoiddesign complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent removes the complex rack and pinion drive mechanism from the spacer device design. Instead, it uses a simpler adjusting element with a groove and a fastening element that can be positioned at different locations along the groove to achieve width adjustment. This extraction of the complex mechanical drive system resolves the contradiction by maintaining adjustability while eliminating design complexity.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The adjusting element is segmented into a base portion and an extending portion that can be selectively positioned. The fastening element can be located at different positions along the groove, creating discrete adjustment steps without requiring a complex continuous adjustment mechanism. This segmentation approach provides width adjustment capability while keeping the design simple.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If a rack and pinion drive is used for width adjustment, then the spacer device can be adjusted, but the manufacture and assembly become relatively complex

Engineering Contradiction:
Improvewidth adjustment capabilityVSAvoidmanufacturing ease
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent extracts the complex rack and pinion drive mechanism and replaces it with a simpler structure consisting of a groove in the adjusting element and a positionable fastening element. This dramatically simplifies manufacturing and assembly processes while maintaining the essential width adjustment capability.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of using a mechanical drive system (rack and pinion) to achieve adjustment, the patent inverts the approach by using a positionable fastening element along a groove to directly set the width. This inversion of the adjustment mechanism simplifies manufacturing and assembly.

Inventive Principle:
Principle #13The other way round (Inversion)

3Device complexity

If fixed width spacers are used, then the design is simple, but the spacer device can only accommodate selected widths

Engineering Contradiction:
Improvedesign simplicityVSAvoidwidth adjustment capability
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent transforms the spacer device from a fixed-width design to a dynamically adjustable design. The fastening element can be positioned at different locations along the groove in the adjusting element, allowing the width to be changed as needed. This dynamic capability is achieved with minimal added complexity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The adjusting element with the groove and positionable fastening element provides multi-functionality, allowing the same basic structure to accommodate multiple width settings. This universal design approach enables width adjustment capability while maintaining design simplicity.

Inventive Principle:
Principle #6Universality (Multi-functionality)
