Pliable Rock Salt Sheet for Uniform Snow Melting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current rock salt applications for melting snow are inefficient as they often leave uncovered areas and require extensive manual effort, with the risk of messy residues and hazardous cold exposure.
Innovation Solution
A roll of perforated sheets coated with a water-soluble adhesive, containing a snow and ice melting compound like rock salt, which can be easily applied to cover surfaces and completely dissolve after use, ensuring thorough coverage and minimal residue.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If rock salt is spread manually on surfaces, then snow and ice can be melted, but the coverage is haphazard and spots may be missed
Solution Approach 1:
The rock salt is divided into individual particles that are separately coated with adhesive, allowing each particle to be precisely placed when the sheet is applied to the surface, ensuring complete and uniform coverage without missing spots
Solution Approach 2:
The invention creates a composite material by coating rock salt particles with water-soluble adhesive, forming a sheet structure that combines the melting function of rock salt with the precise placement capability of an adhesive sheet
2Manufacturing precision
If rock salt is spread in large quantities to ensure complete coverage, then all areas are covered, but messy residue is left behind
Solution Approach 1:
The adhesive component is extracted to be water-soluble, allowing it to be easily removed after serving its binding function, thus eliminating the harmful residue effect while maintaining complete coverage
Solution Approach 2:
The adhesive parameter is changed to be water-soluble, transforming it from a permanent binding agent into a temporary one that dissolves after use, eliminating residue while ensuring complete initial coverage
3Area of stationary object
If extensive manual effort is spent spreading rock salt to cover the surface, then coverage is achieved, but time and energy are wasted
Solution Approach 1:
The rock salt particles are pre-coated with adhesive and pre-formed into sheets during manufacturing, so that when applied, they are ready to stick and cover the surface immediately without requiring manual spreading or positioning, dramatically reducing application time
Solution Approach 2:
The manual mechanical spreading action is replaced by the adhesive bonding mechanism, which automatically holds the rock salt particles in place on the surface, eliminating the need for continuous manual effort to maintain coverage

Function Achieved in This Case
The solution provides a convenient, comprehensive, and residue-free method for melting snow and ice, reducing manual effort and ensuring safe walking conditions by creating a clear path without leaving any residue.
Implementation Method 1
a water-soluble adhesive coating applied to the particles of the snow and ice melting compound to bind the particles to form a sheet
Implementation Method 2
a plurality of particles of a snow and ice melting compound... the sheet is dissolvable
Implementation Method 3
allowing the snow and ice melting sheet to melt the area of snow and ice

AI summary
A device for melting snow includes a snow melting sheet formed of a plurality of particles of a snow and ice melting compound. The sheet is coated with a water-soluble adhesive coating applied to the particles of the snow and ice melting compound to bind the particles to form a sheet. After an area of ice and snow is melted with the sheet, the sheet simply dissolves. The sheets are presented in either a roll with perforations for tearing or a stack of connected or disconnected sheets.
