Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The food industry faces challenges in removing non-trans fat soils and sunscreen stains due to their tendency to polymerize and cause fires, and existing cleaning methods are ineffective and environmentally unfriendly.
Innovation Solution
Incorporating a chelating agent into cleaning compositions to hinder polymerization of non-trans fats and facilitate the removal of sunscreen components, which can be used in laundry detergents, hard surface cleaners, and as a pretreatment or rinse treatment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional cleaning methods are used to remove non-trans fat soils, then cleaning effectiveness is improved, but the risk of spontaneous combustion increases due to polymerization
Solution Approach 1:
A chelating agent is introduced as an intermediary substance that binds to metal ions catalyzing the polymerization of non-trans fats. This mediator prevents the harmful polymerization reaction while allowing the cleaning process to proceed effectively, thus resolving the contradiction between cleaning effectiveness and fire risk
Solution Approach 2:
The invention changes the chemical environment by adjusting pH levels and introducing chelating agents that modify the reaction parameters. This prevents polymerization while maintaining cleaning effectiveness, addressing the contradiction between productive cleaning and harmful combustion risk
2Productivity
If bleach and traditional pretreatments are used to remove sunscreen stains, then stain removal is attempted, but the stains remain visible as yellow patches after washing
Solution Approach 1:
The invention changes the chemical parameters of the cleaning system by using low pH environments and specific chelating agents that effectively dissolve and remove sunscreen components containing avobenzones and oxybenzones, achieving reliable stain removal where traditional high pH methods failed
Solution Approach 2:
The invention replicates the effective cleaning mechanism used for non-trans fats and applies it to sunscreen stains, using similar chelating agents and pH control strategies that have proven effective for one type of stain to successfully address another difficult-to-remove stain type
