Surface Sampling Device with Extended Protective Layer Grip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surface sampling devices using adhesive patches face difficulties in removing the protective sheet, leading to increased time, risk of contamination, and reduced adhesive effectiveness, especially in industrial environments with challenging conditions and surfaces.
Innovation Solution
A device with a flat material layer and a protective layer, where a portion of the protective layer extends beyond the surface portion for easy removal, and a gripping device is used to facilitate the removal process, reducing direct human contact and contamination risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the protective sheet is removed manually to expose the adhesive surface, then the adhesive patch can be used, but the process becomes time-consuming and increases contamination risk
Solution Approach 1:
The protective sheet is divided into two functional parts: a first protective portion that remains on the adhesive patch to protect the adhesive surface, and a second protective portion that extends beyond the boundary to serve as a grip handle. This segmentation allows the adhesive surface to be protected while providing an easy-to-grab extension for removal, eliminating the need for manual peeling and reducing contamination risk.
2Adaptability or versatility
If the adhesive patch is applied to difficult-to-reach surfaces in industrial environments, then surface sampling can be performed, but the risk of fall and contamination increases
Solution Approach 1:
The gripping function is extracted from the adhesive patch body and transferred to the extended second protective portion. This allows the adhesive patch to maintain its protective function while the extended portion serves as a safe grip handle that can be manipulated from a safe distance, reducing contamination risk when applying to difficult-to-reach surfaces.
3Ease of operation
If the protective sheet is completely removed to expose the adhesive surface, then the adhesive patch can be attached, but dirt and contaminants may enter the sampling compartment
Solution Approach 1:
The first protective portion is designed to remain on the adhesive patch as a preliminary protective barrier. This pre-established protection ensures that the adhesive surface and sampling compartment remain protected from dirt and contaminants during handling and application, eliminating the need to completely remove the protective sheet and thus preventing contamination.
