Solution Overview

Problem

Users face uncertainty in selecting the right cleaning product for their needs, and commercially available cleaning products often result in significant water waste, plastic waste, and an unfavorable packaging-to-cleaning-agent ratio due to low active ingredient concentration and large, single-use plastic bottles.

Innovation Solution

A mixing system set comprising separately stored surfactant, solvent, acidic, and alkaline components, along with a mixing device, allows users to produce customized cleaning agents on-site, reducing plastic waste by using reusable containers and ensuring easy handling and safe application through controlled mixing sequences.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If cleaning agents are produced in large, single-use plastic bottles with low active ingredient concentration, then packaging and distribution are simplified, but plastic waste and water waste increase significantly

Engineering Contradiction:
Improvepackaging and distribution simplicityVSAvoidplastic waste and water waste
Core Design Contradiction:
Ease of manufactureVSLoss of substance

Solution Approach 1:

The cleaning agent is segmented into multiple separate components (surfactant component, solvent component, acidic component, alkaline component) that are stored individually and mixed at the point of use. This segmentation eliminates the need for large single-use plastic bottles while reducing waste, as users only mix the components needed for each cleaning task rather than disposing of entire bottles.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The mixing system provides a universal platform that can produce multiple types of cleaning agents (glass cleaner, bathroom cleaner, dish soap, all-purpose cleaner, floor cleaner) from a single set of components. This multi-functionality reduces the need for multiple separate product packages, thereby reducing plastic waste while maintaining ease of use.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple cleaning agent types are offered in separate packages, then users have more product variety, but selection complexity and uncertainty increase

Engineering Contradiction:
Improveproduct varietyVSAvoidselection process complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

A single mixing system set with four basic components can produce multiple types of cleaning agents (glass cleaner, bathroom cleaner, dish soap, all-purpose cleaner, floor cleaner). This universal approach simplifies the selection process by providing one system that adapts to various cleaning needs rather than requiring users to choose from many separate products.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system includes a control unit that guides users through the mixing process and provides feedback on the correct proportions and sequences for different cleaning agent types. This feedback mechanism eliminates selection uncertainty by clearly indicating how to mix components for specific cleaning purposes.

Inventive Principle:
Principle #23Feedback

3Productivity

If surfactant component is mixed directly with water, then the cleaning agent is activated, but lump formation occurs that complicates handling

Engineering Contradiction:
Improvecleaning agent activationVSAvoidhandling ease
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The system performs preliminary mixing by first combining the surfactant component with the solvent component before adding water or other components. This preliminary action prevents lump formation by ensuring the surfactant is properly solubilized in the solvent before water is introduced, thereby maintaining ease of handling while activating the cleaning agent.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The solvent component acts as an intermediary between the surfactant component and water. By first mixing the surfactant with the solvent, the system creates a stable intermediate mixture that prevents lump formation when water is subsequently added, ensuring easy handling throughout the mixing process.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Ease of operation

If cleaning agents are prepared in advance for storage, then convenience is improved, but preservatives and stabilizers are required

Engineering Contradiction:
ImproveconvenienceVSAvoidpreservatives and stabilizers
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system enables users to prepare cleaning agents on-demand at the point of use, eliminating the need for advance preparation and long-term storage. This self-service approach removes the requirement for preservatives and stabilizers while maintaining convenience, as users mix components only when needed and use them immediately.

Inventive Principle:
Principle #25Self-service
