Solution Overview

Problem

Existing cleaning compositions are ineffective for hard-to-reach surfaces like gutters, as they require physical devices and assistance to remove dirt and debris, which is not feasible for inaccessible areas.

Innovation Solution

Development of cleaning compositions comprising non-ionic surfactants, quaternary ammonium compounds, citrus terpenes, chelating agents, and water, applied without physical assistance using a low-pressure delivery system, allowing the composition to remain in contact with the surface to dislodge dirt and debris before rinsing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If cleaning compositions require physical devices and force (sponge, brush, pressurized water) to remove dirt and debris, then cleaning effectiveness is improved, but accessibility to hard-to-reach surfaces like gutters deteriorates

Engineering Contradiction:
Improvecleaning effectivenessVSAvoidaccessibility to hard-to-reach surfaces
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The cleaning composition is formulated to automatically dislodge and remove dirt and debris from gutter surfaces without requiring physical cleaning devices or human assistance. The composition contains surfactants and chelating agents that work autonomously to break down soil, grease, and organic matter, allowing the surface to clean itself through simple application and rinsing

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The invention replaces mechanical cleaning systems (brushes, sponges, pressurized water equipment) with a chemical cleaning system based on nonionic surfactants and chelating agents. This substitution eliminates the need for physical devices and mechanical force, enabling cleaning of hard-to-reach surfaces through chemical action alone

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If cleaning compositions use strong chemical agents to remove heavy soil and grease, then soil removal capability is improved, but surface stability and potential for damage deteriorates

Engineering Contradiction:
Improvesoil removal capabilityVSAvoidsurface stability
Core Design Contradiction:
ReliabilityVSStability of the object's composition

Solution Approach 1:

The invention uses nonionic surfactants with specific HLB values and chelating agents at optimized concentrations to achieve effective soil removal while maintaining surface stability. The formulation parameters are carefully controlled to ensure the cleaning action is sufficient for heavy soil and grease removal without being corrosive to gutter materials

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The cleaning composition is formulated as a composite system containing multiple nonionic surfactants (such as alcohol ethoxylates and amine oxides) combined with chelating agents like EDTA. This composite formulation provides synergistic effects where the surfactants handle organic soil and grease while the chelating agents manage inorganic deposits, collectively achieving comprehensive soil removal without damaging the surface

Inventive Principle:
Principle #40Composite materials
