Solution Overview

Problem

The environmental impact of single-use plastic packaging in cleaning products is significant due to low recycling rates and high waste generation, necessitating a shift towards more sustainable formulations that reduce packaging waste.

Innovation Solution

Development of stable, anhydrous cleanser concentrate formulations in solid tablet form, comprising acidic cleaners, basic cleaners, and surfactants, which eliminate the need for water and associated plastic packaging by using a direct compression process and medium-chain triglyceride (MCT) oil to prevent sticking during tablet production.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If liquid or gel cleaning products are packaged in plastic containers, then the products are easy to use and dispense, but single-use plastic packaging generates significant waste and environmental harm

Engineering Contradiction:
Improveease of useVSAvoidpackaging waste
Core Design Contradiction:
Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The invention changes the physical state of the cleaning product from liquid/gel to solid tablet form by removing water content. This parameter change eliminates the need for plastic packaging while maintaining cleaning effectiveness, directly resolving the contradiction between ease of use and packaging waste

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The cleaning product is segmented into concentrated active ingredients in tablet form, separating the essential cleaning components from water. This segmentation allows the product to be packaged without plastic containers while retaining functionality when activated with water at the point of use

Inventive Principle:
Principle #1Segmentation

2Object-generated harmful factors

If water is removed from cleaning formulations to eliminate plastic packaging, then packaging waste is reduced, but the formulation stability and effectiveness may be compromised

Engineering Contradiction:
Improvepackaging wasteVSAvoidformulation stability
Core Design Contradiction:
Object-generated harmful factorsVSStability of the object's composition

Solution Approach 1:

The invention uses composite materials including medium-chain triglyceride (MCT) oil combined with cleaning agents to create a stable anhydrous formulation. The MCT oil acts as a carrier and stabilizer, ensuring the concentrated ingredients remain stable without water while maintaining cleaning effectiveness

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

MCT oil serves as an intermediary substance that enables the stabilization of concentrated cleaning ingredients in anhydrous form. It mediates between the need for water removal and the requirement for formulation stability, allowing the active ingredients to remain stable without water present

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of manufacture

If MCT oil is added to powder blend to prevent sticking during compression, then tablet production is improved, but excess oil may cause the powder to stick to the tablet press

Engineering Contradiction:
Improvetablet productionVSAvoidsticking to equipment
Core Design Contradiction:
Ease of manufactureVSObject-generated harmful factors

Solution Approach 1:

The invention applies MCT oil locally to specific surfaces that contact the powder during compression, rather than uniformly throughout the entire powder blend. This localized application prevents sticking at critical contact points while avoiding excess oil that would cause the powder to adhere to the tablet press

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The invention uses a controlled, partial amount of MCT oil - sufficient to prevent sticking during compression but not excessive enough to cause the powder to adhere to the tablet press. This precise dosing resolves the contradiction between needing enough oil for production ease and avoiding too much oil that would cause equipment sticking

Inventive Principle:
Principle #16Partial or excessive action
