Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If the position of the suction nozzle is adjusted by changing the stop position in the swinging path, then the distance between the suction opening and the yarn winder can be modified, but the positional accuracy cannot be fully achieved due to device material or mounting configuration limitations

Engineering Contradiction:
Improvepositional accuracy of suction nozzleVSAvoidcomplexity of position adjustment mechanism
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The invention introduces a position adjustment mechanism that allows the rotation center of the body part to be dynamically changed. This enables the suction nozzle to be positioned with high precision relative to the yarn winder by adjusting the rotation center position, overcoming the limitations of fixed mounting configurations.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The invention changes the parameter of the rotation center position of the body part to achieve precise positioning of the suction nozzle. By adjusting this geometric parameter, the relative position between the suction opening and yarn winder can be accurately controlled without increasing overall device complexity.

Inventive Principle:
Principle #35Parameter changes

2Manufacturing precision

If the rotation center of the body part is adjusted to change the distance between the yarn capturer and the contact roller, then the positioning accuracy is improved, but the manufacturing complexity increases

Engineering Contradiction:
Improvepositioning accuracy of yarn capturerVSAvoidcomplexity of position adjustment mechanism
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The invention implements a position adjustment mechanism that enables dynamic repositioning of the rotation center. This allows the yarn capturer to be accurately positioned relative to the contact roller during operation or assembly, improving positioning accuracy without requiring complex manufacturing processes.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The invention segments the position adjustment function into a separate mechanism that can be independently implemented. This segmentation allows the rotation center position to be adjusted without redesigning the entire device, thereby improving positioning accuracy while controlling manufacturing complexity.

Inventive Principle:
Principle #1Segmentation

3Manufacturing precision

If the suction mouth position is adjusted relative to the contact roller, then the yarn capture accuracy is improved, but the manufacturing time and part costs increase

Engineering Contradiction:

Solution Approach 1:

The invention uses parameter changes by adjusting the rotation center position to achieve precise yarn capture positioning. This approach improves capture accuracy through geometric parameter adjustment rather than requiring complex manufacturing processes or additional parts, thereby maintaining ease of manufacture.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The position adjustment mechanism allows the device to be self-adjusting during assembly or operation. This self-service capability enables accurate positioning of the suction mouth relative to the contact roller without requiring external intervention or complex manufacturing procedures, reducing both manufacturing time and part costs.

Inventive Principle:
Principle #25Self-service
