Solution Overview

Problem

Existing methods for preparing and acting on fluids in containers, such as liquefying and removing thixotropic fluids, are laborious and often result in unsatisfactory residual amounts, necessitating manual intervention and inefficient processing.

Innovation Solution

The use of a scraper to mechanically detach fluid from the container walls, combined with a wiper to remove adhering fluid and a pump to homogenize and return the fluid, eliminating the need for manual handling and stirring elements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual preparation and removal methods are used for fluids in containers, then operational flexibility is maintained, but labor intensity increases and residual amounts are high

Engineering Contradiction:
Improvelabor intensityVSAvoidmanual intervention
Core Design Contradiction:
Ease of operationVSExtent of automation

Solution Approach 1:

The system enables automated self-service processing where the pump and wiper components automatically prepare and remove fluid from the container without manual intervention. The pump circulates fluid through the container while the wiper mechanically removes adhering fluid, creating a self-contained automated system that eliminates the need for manual preparation and removal operations

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Manual mechanical operations are replaced by an automated pump-driven circulation system and automated wiper mechanism. The pump provides automated fluid circulation and the wiper provides automated mechanical removal of adhering fluid, substituting manual labor with an integrated automated mechanical system that reduces labor intensity while improving removal effectiveness

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Loss of substance

If conventional removal methods are used, then simple equipment is required, but residual amounts in the container increase

Engineering Contradiction:
Improveresidual amountsVSAvoidequipment structure
Core Design Contradiction:
Loss of substanceVSDevice complexity

Solution Approach 1:

The removal system is segmented into distinct functional components: a pump for fluid circulation and a wiper for mechanical removal of adhering fluid. This segmentation allows each component to perform its specific function optimally - the pump handles bulk fluid movement while the wiper addresses fluid adhering to container walls - thereby minimizing residual amounts without requiring overly complex integrated equipment

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The pump serves multiple functions: it circulates fluid through the container, maintains fluid movement during the wiper operation, and facilitates overall fluid preparation. This multi-functionality allows the system to achieve low residual amounts through coordinated action of circulation and mechanical removal without requiring separate specialized equipment for each function, thereby managing device complexity

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

3Stability of the object's composition

If stirring elements are used for fluid homogenization, then mixing effectiveness is improved, but maintenance requirements and energy consumption increase

Engineering Contradiction:
Improvefluid homogeneityVSAvoidmaintenance
Core Design Contradiction:
Stability of the object's compositionVSEase of repair

Solution Approach 1:

The stirring element is extracted and replaced by a pump-driven circulation system. The pump circulates fluid through the container repeatedly, achieving homogenization through continuous circulation rather than mechanical stirring. This extraction eliminates the stirring element entirely, reducing maintenance requirements while maintaining fluid homogeneity through the circulation mechanism

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The system uses hydraulic principles where the pump creates fluid circulation and movement through pressure-driven flow. Fluid is pumped through the container and back repeatedly, using hydraulic circulation to achieve homogenization without mechanical stirring elements. This hydraulic approach reduces maintenance needs compared to mechanical stirrers while effectively homogenizing the fluid composition

Inventive Principle:
Principle #29Pneumatics and hydraulics
