Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a chip forming device with shearing edge and cutting tool is used to separate chips of different geometries, then the versatility of chip separation is improved, but the device complexity and operator skill requirement increase

Engineering Contradiction:
Improvechip geometry adaptabilityVSAvoidadjustment complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies parameter changes by enabling the cutting edge position to be adjusted in multiple directions (translational and rotational), allowing the same cutting tool to adapt to different chip geometries by changing its spatial parameters rather than requiring multiple specialized tools

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The cutting edge is designed to be movable and rotatable, transforming a static cutting tool into a dynamic one that can adapt its configuration during operation to handle various chip types effectively

Inventive Principle:
Principle #15Dynamics

2Reliability

If the cutting edge position is fixed, then the device complexity is reduced, but the ability to cut through thin and tough chips reliably deteriorates

Engineering Contradiction:
Improvechip cutting reliabilityVSAvoidcutting edge adjustment mechanism
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The cutting edge is designed to be movable and rotatable, allowing dynamic adjustment of its position and orientation to optimize cutting conditions for different chip types, thereby improving reliability without requiring multiple fixed cutting tools

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The adjustment mechanism is segmented into independent directional adjustments (translational and rotational), allowing each degree of freedom to be optimized separately for different cutting scenarios

Inventive Principle:
Principle #1Segmentation

3Manufacturing precision

If extensive operator knowledge and skill are required to adjust the cutting device, then the manufacturing precision of chip geometry can be improved, but the ease of operation deteriorates

Engineering Contradiction:
Improvechip separation precisionVSAvoiddevice setup ease
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The system enables operators to adjust and optimize cutting parameters independently without requiring extensive external expertise, making the device self-sufficient and easier to operate while maintaining precision

Inventive Principle:
Principle #25Self-service
