Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for laminating FRP sheets with different fiber directions face accuracy issues in detecting the space between the ends of the sheets due to hanging or fluffing of fibers, affecting the precision of optical sensors.
Innovation Solution
A sheet space-detecting device with a light-detecting sensor and a spacer system that supports the ends of the FRP sheets, ensuring they are separated from a reference surface, allowing for accurate detection of the space between them.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If FRP sheets are conveyed and positioned for lamination, then the lamination process can be performed, but the front end and rear end of the sheets may hang down or fibers may fluff, causing variations in detection accuracy of the space
Solution Approach 1:
A support member is introduced as an intermediary element between the FRP sheets and the conveyor system. This support member extends from the rear end of the preceding sheet to the front end of the following sheet, providing continuous support that prevents the sheet ends from hanging down or fluffing. By using this intermediary support structure, the detection accuracy of the space between sheets is improved without compromising the lamination process
Solution Approach 2:
The support member is positioned in advance before the optical sensor detects the space between sheets. By preliminarily supporting the sheet ends in a controlled position, the system ensures that the sheets maintain their intended configuration during the detection process, eliminating the problem of hanging or fluffing that would otherwise occur during conveyance and positioning
2Manufacturing precision
If an optical space-detecting sensor is arranged to manage the size of space between sheets, then the lamination positioning can be controlled, but the hanging or fluffing of sheet ends reduces the reliability of detection
Solution Approach 1:
The support member acts as a mediator that ensures the sheet ends maintain a consistent, controlled position relative to each other. This intermediary structure eliminates the variability caused by hanging or fluffing, allowing the optical sensor to reliably detect the space between sheets with consistent accuracy throughout the lamination process
Solution Approach 2:
The support member changes the physical state of the sheet ends from an unstable, variable configuration to a stable, controlled configuration. By modifying the position and support conditions of the sheet ends, the system ensures that the detection parameters remain consistent, thereby improving both manufacturing precision and detection reliability
