Solution Overview
Problem
Existing machines for producing reels of web products struggle with identifying and correcting geometric defects such as non-uniform diameters, core misalignment, and irregular windings, leading to sub-optimal production quality and efficiency.
Innovation Solution
A machine equipped with a pick-up zone, moving apparatus, and evaluation apparatus that measures various geometric parameters of reels, including outer diameter, width, core alignment, and surface irregularities, using sensors and encoders to ensure accurate quality control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional winding machines are used to produce reels, then production speed and quantity can be maintained, but geometric defects such as non-uniform diameters, core misalignment, and irregular windings occur
Solution Approach 1:
The patent implements a feedback mechanism where sensors continuously monitor geometric parameters (diameter, core alignment, winding regularity) during the winding process. The collected data is fed back to the control system, which automatically adjusts winding parameters to correct deviations in real-time, thereby maintaining both high productivity and manufacturing precision
Solution Approach 2:
The patent replaces traditional mechanical measurement and adjustment systems with automated sensor-based detection and electronic control systems. This substitution enables continuous monitoring and precise control of geometric parameters without interrupting the winding process, resolving the contradiction between production speed and precision
2Manufacturing precision
If automated evaluation systems are added to detect geometric parameters, then manufacturing precision and quality control improve, but device complexity increases
Solution Approach 1:
The patent designs the evaluation system with multi-functional sensors that can detect multiple geometric parameters (diameter, core alignment, winding regularity) simultaneously using a single integrated platform. This universal approach improves manufacturing precision while minimizing the increase in device complexity by avoiding multiple separate measurement systems
Solution Approach 2:
The evaluation system is designed to be self-calibrating and automatically adjusts measurement parameters based on the specific reel being evaluated. The system performs self-diagnosis and maintains optimal operation without requiring complex external calibration equipment or frequent manual intervention, thereby improving precision without proportionally increasing complexity
