Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tentering processes require manual correction of fabric deformation, leading to imprecise results and reduced efficiency due to the need for manual inspection and adjustment of fabric patterns during the tentering process.
Innovation Solution
A tenter system with an introduced-fabric design pattern correction unit, a first scanning unit, and a central processing unit that automatically corrects fabric patterns by comparing standard and discharged images, adjusting lateral width and supply speed to align the fabric design with the standard pattern.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual correction of fabric design pattern is performed during tentering process, then the fabric deformation can be corrected, but work efficiency is significantly reduced and correction precision is insufficient
Solution Approach 1:
The patent replaces the manual mechanical inspection and correction system with an automated opto-electronic system. An opto-electronic reader scans the fabric design pattern and detects deviations, while a computerized control system processes the data and commands actuators to make precise corrections, eliminating manual labor and significantly improving both precision and efficiency
Solution Approach 2:
The patent creates an optical copy (image) of the fabric design pattern using an opto-electronic reader. This digital copy is then processed by a computerized system to detect deviations from the intended pattern, allowing for precise measurement and correction without manual inspection
2Reliability
If manual inspection and correction of fabric design pattern is performed continuously, then deformation can be prevented, but time consumption increases and correction accuracy remains insufficient
Solution Approach 1:
The patent implements continuous automated monitoring and correction of the fabric design pattern throughout the tentering process. The opto-electronic reader continuously scans the fabric, and the computerized system continuously processes data and controls actuators, ensuring uninterrupted deformation prevention without manual intervention delays
Solution Approach 2:
The patent establishes a closed-loop feedback system where the opto-electronic reader continuously detects the actual fabric design pattern, the computerized system compares it with the intended pattern, and actuators make real-time corrections based on detected deviations, ensuring continuous deformation prevention with high accuracy
