Solution Overview

Problem

Existing vehicle exterior surface cleaning compositions fail to effectively remove iron deposits without unpleasant odors and do not provide a visual indication of iron removal, leading to potential damage from iron-induced reactions.

Innovation Solution

A vehicle exterior surface cleaning composition incorporating a benzenediol, which reacts with iron to form a brightly colored chelate, thereby visually indicating iron removal and minimizing odor production.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional iron removal compositions (thioglycolate) are used, then iron removal effectiveness is improved, but unpleasant odor is generated

Engineering Contradiction:

Improveiron removal effectivenessVSAvoidunpleasant odor

Core Design Contradiction:

ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent changes the chemical parameters by replacing thioglycolate with benzenediol as the iron-chelating agent. This substitution maintains iron removal effectiveness while eliminating the unpleasant odor associated with hydrogen sulfide and ammonia emissions from conventional thioglycolate formulations.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent employs a disposable color-changing indicator system where the benzenediol forms a temporary colored complex with iron that can be easily rinsed away. This eliminates the need for persistent odor-control mechanisms while maintaining effective iron removal.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

2Reliability

If conventional cleaning detergents are used, then general dirt removal is improved, but iron deposits remain and cause damage

Engineering Contradiction:

Improvegeneral cleaning effectivenessVSAvoidiron-induced damage

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent creates a multi-functional cleaning composition that combines general surfactant-based cleaning capabilities with specific iron-chelating properties. The benzenediol provides both visual indication of iron presence and chemical complexation to remove iron deposits, while surfactants handle general contaminants.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent incorporates a color-changing mechanism where the benzenediol forms a colored complex with iron deposits. This visual indicator allows users to detect and target iron contamination areas, improving the effectiveness of iron removal while the same formulation provides general cleaning protection.

Inventive Principle:

Principle #32Color changes

3Reliability

If manual rubbing is used to remove contaminants, then removal effectiveness is improved, but surface marring occurs

Engineering Contradiction:

Improvecontaminant removal effectivenessVSAvoidsurface integrity

Core Design Contradiction:

ReliabilityVSStrength

Solution Approach 1:

The patent replaces mechanical rubbing with a chemical solution-based approach. The benzenediol and surfactant formulation chemically complexes with and lifts iron deposits from the surface, eliminating the need for abrasive mechanical action that causes marring while maintaining effective contaminant removal.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

A vehicle exterior surface cleaning composition includes at least one benzenediol A surfactant and a thioglycolate are also present in an aqueous diluent. A method of cleaning a vehicle exterior surface is also provide that includes the composition being applied to a vehicle exterior surface. After sufficient contact time, the composition loosens iron containing debris before removing the composition to clean the surface. The composition changes color upon contact with the iron containing debris to provide a visual signal of contamination. The composition removes iron containing debris with limited odor of hydrogen sulfide or ammonia.
