Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drop cloths used by painters often slip on surfaces, increasing the risk of falls due to insufficient resistance, as the working surfaces do not provide enough traction to keep the cloths in place.
Innovation Solution
A multi-layered non-slip mat comprising a top woven layer, a middle synthetic polymer layer, and a bottom PVC resin and polyester mesh layer, bonded through lamination, with an adhesive coating material applied to enhance frictional force, specifically using styrene ethylene butylene styrene (SEBS) for increased slip resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a simple drop cloth is used to protect surfaces, then the protective function is provided, but the cloth slips on working surfaces due to insufficient friction
Solution Approach 1:
The mat is divided into three distinct layers: a top woven layer for protection, a middle adhesive layer for bonding, and a bottom slip-resistant layer with raised patterns for friction. This segmentation allows each layer to perform its specific function optimally while working together to solve the slipping problem.
Solution Approach 2:
The invention uses composite material construction combining different materials with complementary properties: the top layer uses woven material for durability, the middle layer uses adhesive material for bonding, and the bottom layer uses material with raised patterns for enhanced friction. This composite structure resolves the contradiction by integrating multiple material properties into a single functional unit.
2Reliability
If adhesive coating material is applied to increase friction, then slip resistance is improved, but the manufacturing process becomes more complex
Solution Approach 1:
The adhesive coating material is heated to a specific temperature range (180-190°C) to achieve optimal viscosity for coating. This parameter change ensures the material flows properly during application and bonds effectively, simplifying the manufacturing process by establishing clear processing parameters.
Solution Approach 2:
The patent replaces complex multi-step adhesive application mechanisms with a simplified roller coating system. The heated roller applies the adhesive coating in one pass, eliminating the need for brushes, sprays, or multiple coating stages, thus reducing manufacturing complexity while maintaining effective adhesion.
3Manufacturing precision
If the adhesive coating material is heated to high temperature, then the coating quality is improved, but energy consumption increases
Solution Approach 1:
The patent specifies a precise temperature range (180-190°C) for heating the adhesive coating material and roller. This optimized parameter range achieves the necessary coating quality and bonding strength while minimizing energy consumption by avoiding excessive heating. The controlled parameter change balances manufacturing precision with energy efficiency.

AI summary
A non-slip mat comprises an absorbent top layer, an impermeable middle layer, a non-slip bottom layer, and a reinforced outer hem. The reinforced outer hem is formed on at least one edge of the non-slip mat by folding all the layers of non-slip mat at least once such that the bottom layer is facing the bottom layer and the top layer is disposed on both top and bottom surfaces. A method for applying an adhesive coating material on a canvas includes heating the adhesive coating material and at least one roller of an apparatus, advancing the canvas through the apparatus in a forward direction to contact the at least one heated roller, and while advancing the canvas, a uniform coating of the adhesive coating material is applied on a surface of the canvas with the at least one heated roller.
