Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for stripping substrates, such as cardboard, are inefficient in removing portions without causing damage, particularly in ensuring precise separation and minimizing waste, especially when dealing with varying substrate thicknesses and materials.
Innovation Solution
A system employing flexible and soft impact elements rotating around axes to repeatedly collide with the substrate, applying forces that bend and extend the elements to strip away portions, with adjustable rotation speeds and elevations to accommodate different substrates, and an inspection system to detect and correct stripping errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If rigid impact elements are used for substrate stripping, then stripping force is sufficient, but substrate damage increases
Solution Approach 1:
The patent employs flexible impact elements that can bend and deform during impact with the substrate. These elements are made of materials that provide sufficient striking force while absorbing excess energy through elastic deformation, thereby preventing damage to the substrate. The flexibility allows the elements to adapt to varying substrate thicknesses and materials without causing harm.
Solution Approach 2:
The system dynamically adjusts operating parameters including rotation speed, impact force, and elevation of the stripping assembly to match the specific substrate properties being processed. This parameter adaptation ensures optimal stripping effectiveness while minimizing damage risk for different substrate types and thicknesses.
2Device complexity
If fixed rotation speed is used, then system simplicity is maintained, but adaptability to varying substrate properties decreases
Solution Approach 1:
The patent incorporates dynamically adjustable rotation speeds for the impact elements, allowing the system to adapt to different substrate materials and thicknesses. The rotation drive system can vary operational parameters in real-time based on substrate properties, enhancing versatility while maintaining relatively simple mechanical structures.
3Measurement precision
If substrate inspection is performed, then stripping error detection improves, but processing time increases
Solution Approach 1:
The inspection system operates continuously during the stripping process rather than as a separate step. Sensors detect substrate properties and stripping quality in real-time, allowing immediate feedback and correction without interrupting the overall processing flow, thereby minimizing time loss while maintaining high detection precision.

Function Achieved in This Case
The system effectively strips away substrate portions with minimal damage, adapts to varying substrate properties, and reduces errors through dynamic adjustment of operating parameters and conditional stacking, enhancing the reliability and efficiency of the stripping process.
Implementation Method 1
rotating at least one flexible and/or soft impact element(s) so as to repeatedly drive a peripheral portion of the impact element across the substrate plane so as to strip away at least one portion of the substrate
Implementation Method 2
centrifugal force of the rotating of the flexible and/or soft impact element(s) causes the impact element to fully extend so as to eliminate the sag

AI summary
Methods and apparatus for stripping away portions of substrate are disclosed herein. In some embodiments, a flexible and/or soft impact-element(s) rotates around a rotation axis to drive a peripheral portion across a substrate plane of the substrate and/or to repeatedly collide with the substrate. At least some of the collisions are effective to partially dislodge or to strip away portion(s) of substrate.
