Solution Overview

Problem

The production of liquid preparations with solid body content poses challenges such as contamination of production facilities and damage to fragile solid bodies during existing production processes, leading to reduced product quality and unsalable products.

Innovation Solution

A method where at least a portion of the solid bodies are added only in the last method step preceding pouring into a packing unit or during pouring, ensuring the liquid preparation is already ready for use, thereby minimizing exposure to contamination and mechanical stress.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If solid bodies are added during early production steps using existing facilities, then production efficiency is maintained, but contamination risk and damage to solid bodies increase

Engineering Contradiction:

Improveproduction efficiencyVSAvoidcontamination risk and damage

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The liquid preparation is prepared in advance without solid bodies, and solid bodies are added only in the final step before filling. This preliminary preparation allows the liquid matrix to be ready while avoiding exposure of solid bodies to contamination risks and mechanical damage during earlier production stages.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The production process is divided into separate stages: liquid preparation stage and solid body addition stage. This segmentation allows existing facilities to produce the liquid component efficiently while a separate final step incorporates solid bodies under controlled conditions, minimizing contamination and damage.

Inventive Principle:

Principle #1Segmentation

2Stability of the object's composition

If solid bodies are added early in the process, then homogeneous distribution is achieved, but mechanical stress and contamination increase

Engineering Contradiction:

Improvehomogeneous distributionVSAvoidmechanical stress and contamination

Core Design Contradiction:

Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The liquid preparation is completed in advance with all liquid components properly mixed and stabilized. Solid bodies are then added in the final step, allowing them to distribute uniformly throughout the ready-made liquid matrix without undergoing prolonged mechanical stress or contamination exposure.

Inventive Principle:

Principle #10Preliminary action

3Ease of manufacture

If existing production facilities are used, then investment costs are reduced, but product quality and integrity deteriorate

Engineering Contradiction:

Improveinvestment costVSAvoidproduct quality and integrity

Core Design Contradiction:

Ease of manufactureVSManufacturing precision

Solution Approach 1:

The liquid preparation is fully prepared using existing facilities, and solid bodies are added only in the final step before filling. This approach allows utilization of existing production infrastructure while ensuring solid bodies are not exposed to mechanical stress and contamination that would compromise product quality.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

Different parts of the production process have different quality requirements. The liquid preparation phase uses standard existing facilities, while the final solid body addition uses a controlled local environment that protects solid body integrity, combining cost-effectiveness with high product quality.

Inventive Principle:

Principle #3Local quality
