Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the rotor is designed as a one-piece structure, then the manufacturing simplicity is improved, but the flexibility for specific applications deteriorates

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidflexibility for specific applications
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The rotor is divided into two separate components: a rotor wall component and a rotor base component. The rotor wall includes a fiber sliding surface, while the rotor base includes a fiber collection groove. These components are detachably connected, allowing independent selection and optimization of each component's properties for specific applications while maintaining manufacturing simplicity through modular construction.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If the rotor is designed as a multi-part structure, then the flexibility for specific applications is improved, but the stability of the rotor deteriorates

Engineering Contradiction:
Improveflexibility for specific applicationsVSAvoidstability of the rotor
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The rotor is segmented into a rotor wall component and a rotor base component that are detachably connected. This segmentation enables flexibility in selecting component properties while maintaining stability through proper connection design.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different components are assigned specific functional qualities: the rotor wall has a fiber sliding surface optimized for fiber movement, while the rotor base has a fiber collection groove optimized for yarn collection. Each component's local properties are optimized for its specific function, improving overall rotor performance and stability for specific applications.

Inventive Principle:
Principle #3Local quality

3Reliability

If the entire rotor is replaced when parts are worn, then the reliability is improved, but the loss of time and resource consumption deteriorates

Engineering Contradiction:
Improvereliability of the rotorVSAvoiddowntime of the rotor spinning machine
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The rotor is segmented into a rotor wall component and a rotor base component that are detachably connected. When one component becomes worn, only that specific component needs to be replaced rather than the entire rotor, reducing downtime and resource consumption while maintaining rotor reliability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The detachable connection allows individual components to be discarded and replaced independently when worn. The remaining components can be recovered and reused, reducing resource consumption and minimizing machine downtime while ensuring reliable operation.

Inventive Principle:
Principle #34Discarding and recovering
