Solution Overview
Problem
Existing cutting apparatuses for fabrics used in garment production fail to maintain the fabric perfectly still during cutting, leading to suboptimal dimensions and workmanship, and are energy-inefficient due to excessive use of suction or presser rollers.
Innovation Solution
An electrostatic attraction system is employed to securely hold the fabric on a supporting surface using ionizing bars to induce and distribute electrical charges, ensuring the fabric remains flat and stable during cutting, with de-ionizing means for easy removal after processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If suction means are used to hold the fabric on the supporting surface, then the fabric can be retained during cutting, but energy consumption increases significantly and material usage becomes excessive
Solution Approach 1:
The patent replaces the mechanical suction system with an electrostatic field generation system. Ionizing bars create electrostatic attraction forces that hold the fabric on the supporting surface without requiring mechanical suction, thereby eliminating the high energy consumption associated with suction means while maintaining reliable fabric retention during cutting operations
2Reliability
If suction means with plastic film are used to adhere the fabric, then the fabric can be held on the supporting surface, but excessive material is consumed and homogeneous retention is not achieved
Solution Approach 1:
The patent eliminates the need for plastic film by using electrostatic field generation. The ionizing bars create electrostatic attraction that directly adheres the fabric to the supporting surface without requiring any additional film material, thus reducing material consumption to zero while achieving homogeneous retention across the entire fabric surface
Solution Approach 2:
The patent changes the physical state and properties of the supporting surface by generating electrostatic charges on it. This parameter change allows the surface to actively attract and hold the fabric through electrostatic forces, replacing the passive mechanical adhesion method that required plastic film and resulting in more efficient material usage
3Reliability
If presser rollers are used to retain the material, then the fabric can be held during cutting, but the retaining is not optimum and adds mechanical complexity
Solution Approach 1:
The patent replaces the mechanical presser roller system with an electrostatic field generation system. The ionizing bars create electrostatic attraction forces that hold the fabric without requiring any moving mechanical parts, thereby reducing device complexity while maintaining or improving retention effectiveness through uniform electrostatic forces across the fabric surface
