Solution Overview
Problem
Existing detaching technologies fail to effectively detach scrap materials due to shape-dependent adsorption issues, particularly when using multiple adsorption pads in a grid pattern.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all adsorption pads in a grid pattern are used to adsorb the target object, then the adsorption coverage is maximized, but the detachment fails when the film shape does not match the adsorption pattern
Solution Approach 1:
The patent applies the dynamics principle by making the adsorption pad configuration changeable during operation. The system dynamically selects and activates specific adsorption pads based on the detected film shape and position, rather than using a fixed grid pattern. This allows the adsorption system to adapt to different film shapes (rectangular, circular, irregular) and ensures reliable detachment across various target object geometries.
Solution Approach 2:
The patent implements parameter changes by modifying which adsorption pads are active based on the target object's characteristics. The control unit changes the operational state of individual adsorption pads (on/off selection) according to the detected film shape, size, and position. This selective activation optimizes the adsorption pattern to match the specific target geometry, resolving the contradiction between fixed grid coverage and shape adaptability.
2Ease of manufacture
If multiple adsorption pads are arranged in a fixed grid pattern, then the device structure is simple, but it cannot effectively detach scrap materials of various shapes
Solution Approach 1:
The patent applies segmentation by dividing the adsorption system into individually controllable pad units arranged in a grid. Each adsorption pad can be independently selected and controlled, allowing the system to activate only the necessary pads for a given film shape. This segmented approach maintains the simple grid structure while enabling flexible adaptation to different target geometries through selective pad activation.
Solution Approach 2:
The system transitions from a static, fixed-grid adsorption approach to a dynamic configuration where specific pads are selected based on real-time detection of film shape and position. The control unit dynamically adjusts which adsorption pads are active, enabling the simple grid structure to adapt to various film shapes without requiring complex mechanical reconfiguration.
3Adaptability or versatility
If a selection unit and rotation control are added to enable adaptive detachment, then the adaptability to different shapes is improved, but the device complexity increases
Solution Approach 1:
The patent implements universality by using a single adsorption pad array that can perform multiple functions through selective activation and rotation. The same physical pads serve different adsorption patterns depending on which ones are activated and how the assembly is oriented. This multi-functional approach achieves shape adaptability without requiring separate dedicated mechanisms for each film geometry, thereby limiting the increase in device complexity.
Solution Approach 2:
The system achieves adaptability through parameter changes in the control domain rather than physical domain. By changing which adsorption pads are active (selection parameter) and the rotation angle of the adsorption assembly (orientation parameter), the system adapts to different film shapes. This software-based adaptation approach minimizes hardware complexity compared to having mechanically reconfigurable adsorption structures.
