Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing peeling devices face difficulties in efficiently removing reinforcing sheets from substrates, particularly due to limited orthogonal movement of rods, which can lead to increased peeling force and potential resin layer fractures, and are not adaptable to varying objects.
Innovation Solution
A peeling device with a supporting unit, a plate-shaped flexible member, pads, rods, and a control device that allows for sequential bending deformation of the laminate from one-end side, enabling easy peeling and adaptation to different objects by controlling rod positions and joint pivoting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If rods are constrained to move only in axial directions, then device structure is simplified, but bending deformation of reinforcing sheet is inhibited and peeling force increases
Solution Approach 1:
The rod support structure is designed to allow dynamic movement in multiple directions (axial elongation/contraction plus orthogonal pivoting) rather than being fixed in a single direction. This enables the rods to adapt their movement to the bending deformation requirements of the reinforcing sheet during peeling, reducing the force needed while maintaining structural feasibility
Solution Approach 2:
The rod support system is divided into multiple independently controllable rods, each capable of individual axial movement and orthogonal pivoting. This segmentation allows different parts of the reinforcing sheet to undergo bending deformation at different rates and directions, effectively reducing overall peeling force while avoiding the complexity of a fully rigid coupled system
2Device complexity
If rotating body with fixed curved surface is used, then device structure is simplified, but adaptability to changes in objects to be peeled off is reduced
Solution Approach 1:
Instead of a fixed curved surface, the invention uses multiple rods with adjustable positions and pivoting capabilities that can dynamically adapt to different object geometries. The rod positions and angles can be modified based on the specific reinforcing sheet and substrate being peeled, providing versatility while maintaining a relatively simple mechanical structure
Solution Approach 2:
The system allows changes in geometric parameters (rod positions, angles, and movement amplitudes) to adapt to different objects being peeled. This parameter adjustability enables the same device structure to handle various reinforcing sheet configurations without requiring complete structural redesign, balancing simplicity with adaptability
