Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing workpiece holding technologies face challenges in providing sufficient adhesive force while ensuring easy separation without applying a load, particularly for heavy or delicate workpieces, often resulting in bending, twisting, or dropping of the workpiece.
Innovation Solution
A workpiece holding device utilizing a self-adhesive adhesive holding material attached to an elastically deformable belt-like sheet, integrated with a pedestal block through an integrating means, allowing for secure adhesion and easy separation by disengaging the integration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If adhesive force is increased by enlarging adhesive surface area, then holding capability is improved, but peeling process becomes more difficult and requires larger load
Solution Approach 1:
The adhesive surface is divided into multiple independent adhesive regions arranged in an array, allowing selective engagement and disengagement of individual regions during peeling operations, reducing the total load required for separation
Solution Approach 2:
The belt-like sheet is made elastically deformable, enabling dynamic adjustment of the adhesive surface configuration during peeling to reduce resistance and minimize load on the workpiece
2Force
If adhesive holding material is used to hold workpiece, then holding capability is improved, but workpiece may bend or twist causing dropping
Solution Approach 1:
The adhesive holding material is segmented into multiple discrete adhesive regions rather than a continuous adhesive layer, distributing the holding force across multiple points to prevent bending and twisting of the workpiece
Solution Approach 2:
Each adhesive region is optimized with specific properties (adhesive strength, size, spacing) to provide localized holding force appropriate for the workpiece geometry and weight distribution, enhancing overall stability
3Stability of the object's composition
If integrating means is used to integrate pedestal block and belt-like sheet, then holding stability is improved, but separation process becomes more complex
Solution Approach 1:
The integrating means replaces complex mechanical fastening systems with a simpler mechanism that achieves stable integration during holding and allows easy separation through disengagement, reducing overall device complexity

AI summary
Provided is a workpiece holding device capable of surely holding even a heavy workpiece and enabling the held workpiece to be removed without applying a load to it. In the workpiece holding device, a self-adhesive adhesive holding material 2 is attached to one surface of an elastically deformable belt-like sheet 1, the belt-like sheet 1 is locked to a pedestal block 5 having a locking part 4, with the adhesive holding material 2 facing outward, and an integrating means is included which brings a base surface 5a of the pedestal block 5 and the other surface 1a of the belt-like sheet 1 into close contact with each other to integrate them, and in holding the workpiece, the pedestal block 5 and the belt-like sheet 1 are integrated by the integrating means to form a workpiece holding surface, thereby adhesively holding the workpiece, and in removing the workpiece, integration of the pedestal block 5 and the belt-like sheet 1 is disengaged to separate the base surface of the pedestal block and the other surface of the belt-like sheet, thereby being able to peel off the workpiece from the workpiece holding surface.
