Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional hard surface cleaning agents that provide shine and repair effects often require repeated polishing, leave streaks or stickiness, and are not water-soluble, making them expensive and inefficient for use on surfaces like ceramic, porcelain, stone, and glass.

Innovation Solution

A surfactant-containing cleaning agent with phosphoric acid esters of polyether-modified alkyl alcohols, which are effective in low concentrations to produce shine and repair effects without leaving streaks or stickiness, and can be used with hard water, reducing stain formation and maintaining stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If conventional wax/acrylic polymer additives are used to produce shine and repair effect, then a glossy appearance is achieved, but the surface becomes sticky, leaves streaks, and requires repeated polishing

Engineering Contradiction:

Improveglossy effectVSAvoidstickiness and streaks

Core Design Contradiction:

Illumination intensityVSObject-generated harmful factors

Solution Approach 1:

The invention changes the chemical composition parameters by using phosphoric acid esters of polyether-modified alkyl alcohols instead of conventional wax/acrylic polymers. This parameter change maintains the glossy effect while eliminating stickiness and streaks, as the phosphoric acid esters provide shine without forming a sticky film that requires repeated polishing.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The invention replaces expensive, long-lasting wax films with a water-soluble phosphoric acid ester composition that provides temporary shine without the harmful side effects. The composition is designed to be rinsed away easily, eliminating the need for repeated polishing and application of expensive wax products.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

2Ease of operation

If water-soluble ingredients are used to simplify application, then ease of operation improves, but shine and repair effects are reduced

Engineering Contradiction:

Improveapplication simplicityVSAvoidshine effect

Core Design Contradiction:

Ease of operationVSIllumination intensity

Solution Approach 1:

The invention creates a composite material by combining phosphoric acid esters with polyether-modified alkyl alcohols. This composite provides both water solubility for easy application and sufficient shine effect, as the polyether modification enhances the glossy appearance while maintaining water solubility for simplified rinsing.

Inventive Principle:

Principle #40Composite materials

3Illumination intensity

If conventional polishing methods are used to achieve shine, then glossy effect is improved, but time consumption and labor increase

Engineering Contradiction:

Improveshine effectVSAvoidpolishing time

Core Design Contradiction:

Illumination intensityVSLoss of time

Solution Approach 1:

The phosphoric acid ester composition provides self-service shine by forming a glossy film during the cleaning process itself, without requiring subsequent polishing steps. The composition is applied once during cleaning and provides immediate shine, eliminating the need for separate polishing operations and reducing time consumption.

Inventive Principle:

Principle #25Self-service

4Reliability

If wax-like compositions are used to seal surfaces, then durability is improved, but surfaces appear painted and not refreshed

Engineering Contradiction:

Improvesurface sealingVSAvoidnatural appearance

Core Design Contradiction:

ReliabilityVSIllumination intensity

Solution Approach 1:

The invention extracts the sealing function from the composition by using phosphoric acid esters that do not form heavy wax films. Instead of sealing the surface with a thick layer that masks the natural appearance, the composition provides light protection and shine that maintains the surface's natural look while still offering some protective effect.

Inventive Principle:

Principle #2Taking out (Extraction)
