Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual operation is used to fold and handle fabric samples, then the testing process is simple and flexible, but the test results have large errors and low reliability due to human factors affecting fabric position and crease formation
Solution Approach 1:
The patent replaces manual mechanical operations with an automated mechanical system comprising a rotating mechanism, automatic folding mechanism, and crease generating mechanism. The rotating mechanism uses a turntable and rotating cylinders to automatically position and fold fabric samples, eliminating human intervention in the folding process. The crease generating mechanism uses pressing cylinders to automatically create standardized creases, ensuring consistent and reliable test results without human factor interference.
Solution Approach 2:
The automated folding mechanism enables the fabric sample to be folded and positioned by itself through the coordinated action of the rotating mechanism and folding mechanism, without requiring manual handling. The system performs self-positioning and self-folding operations, reducing human interference and improving result reliability.
2Extent of automation
If automated pressing and pressure relief functions are implemented, then the pressing process is improved, but manual operation is still needed to make the sample form a bending and folding state, which introduces manual factors affecting crease position
Solution Approach 1:
The patent replaces manual folding operations with an automated rotating mechanism that uses a turntable and rotating cylinders to precisely position and fold the fabric sample. The rotating cylinders are controlled to rotate between vertical and horizontal orientations, automatically forming the sample into the required bending and folding state without manual intervention, thereby ensuring precise and consistent crease positions.
Solution Approach 2:
The rotating mechanism performs preliminary positioning and folding actions on the fabric sample before it enters the pressing stage. The automatic folding mechanism pre-forms the bending state and crease positions, ensuring that when the sample reaches the pressing mechanism, the creases are already accurately positioned, eliminating the need for manual adjustment and improving manufacturing precision.
3Device complexity
If manual folding is used to create creases, then the equipment structure is simple, but the position where creases emerge is unstable and causes unreliable experimental results
Solution Approach 1:
The patent replaces manual folding with an automated system consisting of a rotating mechanism with controlled cylinders and an automatic folding mechanism. The rotating cylinders are precisely controlled to rotate between vertical and horizontal orientations, and the folding mechanism uses synchronized turning platforms to automatically fold the fabric at predetermined positions. This automated mechanical system ensures stable and precise crease formation, eliminating the instability inherent in manual folding operations.

Function Achieved in This Case
The automatic system ensures precise control over fabric folding and crease recovery testing, significantly reducing human error and enhancing the accuracy of crease recovery angle measurements by mechanically controlling the bending and folding process.
Implementation Method 1
The first vacuum turning platform is square block, with air suction holes on one side of the square block, and the air suction holes are connected with the air suction fan, and the sample is placed on the first vacuum turning platform. The suction holes absorb the two sides of the sample to make the two sides of the sample aligned during the turning process
Implementation Method 2
The first rotating cylinder is adapted to rotate the first finger cylinder between a vertical and a horizontal orientation... The finger cylinder can clamp the sample on both sides of the metal sheet
Implementation Method 3
The crease generating mechanism comprises the first pressing cylinder and the first electromagnetic support block... Pressing cylinder is used to exert constant pressure on the sample
Implementation Method 4
Electromagnetic support block is used to absorb the metal sheet, so that one side of the sample is clamped between the metal sheet and the electromagnetic support block

AI summary
An automatic fabric folding device has a rotating mechanism, an automatic folding mechanism and a crease generating mechanism. The automatic folding mechanism is located below the finger cylinder on one side of the rotating mechanism, and the finger cylinder on the other side of the automatic folding mechanism is fixed with a crease generating mechanism. The two rotating cylinders are central symmetrical with the rotating arm. This accurately controls the bending and folding of the fabric sample through the automatic control technology, and realizes the automatic detection of the fabric crease recovery process. By mechanical and numerical control technology, the parts to be measured are effectively prevented from interference by human factors, and the detection accuracy is improved.
