Solution Overview

Problem

Existing processes for producing gel-like detergents are inflexible, expose sensitive ingredients to high temperatures leading to loss, and struggle with bubble formation and volatile ingredient loss during production.

Innovation Solution

A method involving a batch production line where a premix of water, glycerin, and surfactants is created, then supplemented with fragrances and dyes on a filling line at lower temperatures, minimizing exposure and bubble formation, and allowing for flexible production variations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If all ingredients are mixed in several stages in a batch production line at high temperatures, then the premix can be produced efficiently with good mixing, but sensitive ingredients like fragrances and dyes are exposed to very high temperatures for extended periods leading to partial loss

Engineering Contradiction:
Improveproduction efficiencyVSAvoidloss of sensitive ingredients
Core Design Contradiction:
ProductivityVSLoss of substance

Solution Approach 1:

The production process is divided into two separate lines: a batch production line for mixing the premix without fragrances and dyes, and a filling line where these sensitive ingredients are added at the end. This segmentation allows the premix to be produced efficiently at high temperatures while the sensitive ingredients are protected from thermal degradation by being added only after the hot mixing phase is complete.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The premix is prepared in advance on the batch production line at high temperatures to ensure good mixing and low viscosity, but the sensitive ingredients are reserved and added only at the final stage on the filling line. This preliminary action of preparing the base mixture separately allows subsequent addition of temperature-sensitive components without exposing them to damaging conditions.

Inventive Principle:
Principle #10Preliminary action

2Stability of the object's composition

If vacuum is used to eliminate bubbles during mixing, then bubble formation is reduced, but volatile ingredients especially fragrances are lost

Engineering Contradiction:
Improvebubble eliminationVSAvoidloss of volatile ingredients
Core Design Contradiction:
Stability of the object's compositionVSLoss of substance

Solution Approach 1:

The process separates bubble elimination into two stages: first, the premix is deaerated in the batch production line before fragrances are added, and second, the filling line operates at lower temperatures to minimize bubble formation during final product assembly. This segmentation ensures that vacuum treatment occurs before volatile ingredients are introduced, preventing their loss.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The premix undergoes vacuum treatment and bubble elimination before the volatile fragrances and dyes are added on the filling line. This preliminary deaeration action removes bubbles from the base mixture without exposing volatile ingredients to vacuum conditions that would cause their loss.

Inventive Principle:
Principle #10Preliminary action

3Productivity

If the premix is produced in advance on a batch production line, then continuous production is achieved, but the process becomes inflexible and cleaning effort increases

Engineering Contradiction:
Improvecontinuous productionVSAvoidproduction flexibility
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The production system is segmented into a continuous batch production line for the premix and a flexible filling line for final product assembly. The batch production line can continuously produce the same premix formulation, while the filling line can be quickly reconfigured to add different fragrances and dyes for various end products, providing both efficiency and flexibility.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The batch production line produces a universal premix that can serve multiple product formulations, while the filling line performs the multi-functional role of adding different supplements for various end products. This universality allows the same premix to be used for different final products, maintaining flexibility without sacrificing continuous production capability.

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

4Ease of manufacture

If high temperatures are used on the batch production line, then the premix has low viscosity and mixes well, but temperature-sensitive substances are destroyed

Engineering Contradiction:
Improvemixing easeVSAvoidthermal damage to sensitive substances
Core Design Contradiction:
Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The process segments temperature application: high temperatures are applied only to the premix on the batch production line where mixing ease is required, while the filling line operates at lower temperatures to protect temperature-sensitive substances. This segmentation allows each stage to operate at the optimal temperature for its specific function.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different parts of the production process operate at different temperatures: the batch production line uses high temperatures locally where good mixing is needed, while the filling line uses lower temperatures locally where temperature-sensitive ingredients are handled. This local quality approach optimizes each stage's conditions without compromising the other.

Inventive Principle:
Principle #3Local quality

Function Achieved in This Case

This approach enables continuous, cost-effective, and flexible production with reduced cleaning effort and waste, while preserving temperature-sensitive ingredients by adding fragrances and dyes just before bottling, thus maintaining product quality and variability.
