Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Length of moving object

If the drive spindle is extended to expand the clamping range, then the clamping range is improved, but the device complexity and conversion measures become more complicated

Engineering Contradiction:
Improveclamping rangeVSAvoidconversion measures
Core Design Contradiction:
Length of moving objectVSDevice complexity

Solution Approach 1:

The jaw carrier is divided into a first jaw carrier fixed to the lower part and a second jaw carrier that can be moved. The clamping range is extended by allowing the second jaw carrier to be positioned at different locations on the lower part, rather than extending the entire drive spindle. This segmentation enables flexible adaptation to different workpiece dimensions without complex conversion measures.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The second jaw carrier is designed to be movable relative to the lower part through a guide structure, allowing dynamic adjustment of the clamping range. This dynamic configuration enables the clamping drive to adapt to various workpiece sizes by simply repositioning the second jaw carrier, avoiding the need for complex conversion measures.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If complex conversion measures are taken to adapt the clamping drive to existing conditions, then the adaptability is improved, but the device complexity increases

Engineering Contradiction:
Improveadaptability to workpiece dimensionsVSAvoidconversion measures
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The lower part is designed with a guide structure that universally accommodates different jaw carrier configurations. The guide structure allows the second jaw carrier to be positioned at multiple locations, enabling the same clamping drive to handle various workpiece dimensions without requiring complex conversion measures or specialized components.

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

Solution Approach 2:

The movable second jaw carrier guided by the guide structure provides dynamic adaptability to different workpiece dimensions. This dynamic positioning capability allows the clamping drive to be universally applied to various clamping tasks without complex conversion measures, simply by adjusting the position of the second jaw carrier.

Inventive Principle:
Principle #15Dynamics

3Force

If the clamping force is increased to handle larger workpieces, then the load capacity is improved, but the stability of connections may be compromised

Engineering Contradiction:
Improveclamping forceVSAvoidstability of connections
Core Design Contradiction:
ForceVSStability of the object's composition

Solution Approach 1:

The clamping force is distributed across multiple connection points through the segmented jaw carrier design. The first jaw carrier is fixed to the lower part at multiple locations, and the second jaw carrier is guided by the guide structure at different positions. This segmentation distributes the clamping force evenly across the connection points, maintaining stability even at high clamping forces.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The guide structure is pre-configured on the lower part to guide the second jaw carrier into the correct position before clamping operation. This preliminary positioning ensures that the connections are properly aligned and distributed, preventing instability during high-force clamping operations by ensuring optimal force distribution from the outset.

Inventive Principle:
Principle #10Preliminary action
