Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the rotation speed is increased to improve productivity, then the yarn tension increases causing damage and breakages

Engineering Contradiction:
Improvespinning speedVSAvoidyarn integrity
Core Design Contradiction:
ProductivityVSStrength

Solution Approach 1:

The balloon is divided into multiple stretches (first stretch, second stretch, etc.) separated by tension means. This segmentation allows the yarn to be supported at multiple points, distributing the tension and reducing peak tension values even at high rotation speeds, thereby preventing yarn damage while maintaining productivity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Tension means are introduced as intermediary elements between the yarn feeding means and yarn picking means. These intermediaries support the yarn at multiple points along its path, reducing the overall tension in the yarn while allowing high rotation speeds to be maintained for improved productivity

Inventive Principle:
Principle #24Intermediary (Mediator)

2Area of stationary object

If the balloon diameter is limited to reduce machine size, then the rotation speed must be reduced lowering productivity

Engineering Contradiction:
Improvemachine footprintVSAvoidspinning speed
Core Design Contradiction:
Area of stationary objectVSProductivity

Solution Approach 1:

The invention transitions from a single-plane balloon to a three-dimensional structure with multiple stretches arranged vertically and horizontally. By utilizing multiple dimensions (first stretch, second stretch, etc.), the system achieves high rotation speeds without requiring excessive horizontal space, thus maintaining compact machine footprint while improving productivity

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Strength

If multiple stretches of balloon are created to reduce yarn tension, then the machine complexity increases

Engineering Contradiction:
Improveyarn integrityVSAvoidnumber of tension means
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

Each tension means serves multiple functions: it supports the yarn, reduces tension, and helps define the balloon geometry. This multi-functionality reduces the need for additional specialized components, thereby limiting the increase in machine complexity while achieving multiple stretches of balloon for improved yarn integrity

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

AI summary

PROCESS FOR SPINNING AND/OR TWISTING YARNS, MACHINE FOR SPINNING AND/OR TWISTING YARNS AND METHOD TO TRANSFORM A MACHINE FOR SPINNING AND/OR TWISTING YARNS. A feature of the invention should be a process of yarn spinning and/or twisting, in which a yarn runs between a yarn feeding means (1) towards a yarn picking means, the said yarn picking means being connected to driving means to rotate the yarn picking means at a predetermined speed, in which a stretch of balloon is generated in a point located between the feeding means (1) and the picking means by the presence of twisting means. The fact that the value of the rotation speed of the yarn twisting means is such that it generates a helical path with oscillating spiral diameters along the distance existing between the yarn feeding means (1) and the yarn picking means, so that the path of the yarn, by the operation of the twisting means, creates a body of revolution from a diameter generating a balloon that has at least a hyperboloid structure (E) forming at least two stretches of balloons (B) consecutive to each other. A second feature of the invention should be the yarn spinning and/or twisting machine that includes a yarn feeding means (1) to supply at least a yarn (3), a yarn picking means for the yarn handled (3), twisting means arranged between the yarn feeding means and the yarn picking means that generate diameter generating (DB) a stretch of balloon of the yarn (3) in an area generating a stretch of balloon (B) with a generating diameter (DB), driving means (4) connected to yarn feeding and/or picking, and does not include elements limiting the balloon and is characterized in that the distance (LB) existing between the guiding means and the area generating a stretch of balloon is at least two times the diameter generating the balloon (DB), so that at least two stretches of balloon (B) are generated between the guiding means (8) and the area generating a stretch of balloon. Last, another feature of the invention should be the method to transform a yarn spinning and/or twisting machine including a set in which the height of the stretch of balloon (LB) is increased so that, by operating the twisting means, a body of revolution is created from a diameter generating a balloon that has at least a hyperboloid structure (E) that forms at least two stretches of balloons (B) consecutive to each other.
