Solution Overview

Problem

Commercial kitchens face challenges in removing polymerized airborne grease deposits on floors, which are both unclean and unsafe, particularly from animal and vegetable fats, as existing cleaning solutions are ineffective and inefficient.

Innovation Solution

A concentrated acidic floor cleaner with a high total acid to free acid ratio is diluted with water to create a use solution that effectively removes polymerized soils from floors, including quarry tile and concrete surfaces, while being less irritating to skin and eyes and free of hydrofluoric acid.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing cleaning solutions are used, then they are safe and easy to store, but they are ineffective at removing polymerized grease deposits

Engineering Contradiction:
Improvecleaning effectivenessVSAvoidformulation complexity
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent changes the chemical parameters of the cleaning solution by using a high ratio of total acid to free acid (at least 5:1, or at least 3:1, or at least 2.5:1) and specifying particular acid components (sulfamic acid, sulfuric acid, phosphoric acid, or blends thereof). This parameter change enables the solution to effectively remove polymerized grease deposits while maintaining safety and storage ease.

2Volume of stationary object

If concentrated cleaning products are used, then storage space is reduced, but preparation and handling become more complex

Engineering Contradiction:
Improvestorage spaceVSAvoidpreparation simplicity
Core Design Contradiction:
Volume of stationary objectVSEase of operation

Solution Approach 1:

The patent formulates a concentrated cleaning product with a high total acid to free acid ratio (at least 5:1, or at least 3:1, or at least 2.5:1) that can be effectively diluted with water during use. This parameter optimization allows the product to maintain high cleaning effectiveness in concentrated form while being simple to prepare and handle through straightforward dilution.
