Solution Overview

Problem

Conventional solid detergent tablets have issues with enzyme deactivation due to high temperatures during drying, poor stability due to moisture and environmental factors, and require separate addition of softeners, leading to precipitation and reduced cleaning effectiveness.

Innovation Solution

Incorporating enzyme preparations and softener components as solid particles within detergent tablets, using a formulation of 8-34 parts water-soluble polymer, 14-50 parts surfactant, 0.1-50 parts enzyme preparation, 0.1-50 parts softener preparation, and 1-10 parts foaming agent, with specific polymer types and particle sizes to maintain stability and prevent precipitation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If high temperature drying is used to evaporate water and achieve high concentration and portability, then the detergent tablet achieves high concentration and portability, but the enzyme preparation is deactivated due to high temperature

Engineering Contradiction:
Improveconcentration of detergent ingredientsVSAvoidenzyme activity
Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

The detergent tablet is divided into multiple functional layers: an outer water-soluble polymer coating layer and an inner core containing enzyme preparation and other detergent ingredients. This segmentation allows the enzyme preparation to be protected from high temperature drying while still achieving high concentration and portability of the detergent formulation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A water-soluble polymer coating is introduced as an intermediary layer between the enzyme preparation and the external environment. This coating protects the enzyme preparation from deactivation during high temperature drying while allowing the detergent to maintain its high concentration and portable form.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If liquid enzyme preparation is added by spraying and smearing to increase cleaning power, then the detergent tablet has enhanced cleaning function, but the detergent tablet dissolves and becomes sticky and soft due to excessive water and organic solvent

Engineering Contradiction:
Improvecleaning powerVSAvoidstorage stability
Core Design Contradiction:
ReliabilityVSStability of the object's composition

Solution Approach 1:

The physical state of the enzyme preparation is changed from liquid to solid particles. This parameter change allows the enzyme preparation to be incorporated into the detergent tablet without adding excessive water or organic solvents, maintaining both cleaning power and storage stability while avoiding dissolution and stickiness.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The detergent tablet is formulated as a composite material combining water-soluble polymer, surfactant, solid enzyme preparation particles, and softener preparation. This composite structure provides enhanced cleaning power while maintaining storage stability, as the solid particles are integrated into the matrix rather than added as liquid.

Inventive Principle:
Principle #40Composite materials

3Ease of operation

If cationic softener component is directly added to the detergent to eliminate static electricity, then the softening function is achieved, but precipitation occurs due to mutual absorption of heterogeneous charges between cationic softener and anionic surfactant

Engineering Contradiction:
Improvesoftening functionVSAvoidsolution stability
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The softener preparation is segmented into solid particles that are physically separated from the anionic surfactant in the detergent matrix. This segmentation prevents direct contact between cationic softener and anionic surfactant, avoiding precipitation while maintaining both softening and detergency functions.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The water-soluble polymer matrix acts as an intermediary that physically separates the cationic softener particles from the anionic surfactant. This intermediary structure prevents mutual absorption of heterogeneous charges while allowing both components to function independently - the surfactant for detergency and the softener for static elimination.

Inventive Principle:
Principle #24Intermediary (Mediator)
