Solution Overview

Problem

Conventional dosing devices for viscous media experience leaks, increased setup and cleaning times, and safety risks due to the physical separation of containers and dosing devices, particularly with hazardous materials.

Innovation Solution

A one-piece device integrating a container and an eccentric screw pump or progressing cavity pump, eliminating the need for seals and reducing contact risks, with a design that minimizes leaks and simplifies setup and cleaning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a seal is used to couple the container to the dosing device, then the coupling tightness is improved, but leaks still occur after certain period of use and the setup time increases

Engineering Contradiction:
Improvecoupling tightnessVSAvoidsetup time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The container and dosing device are merged into a single integrated unit where the container wall itself forms part of the pump housing. This eliminates the separate coupling interface and seal requirements, achieving both leak-free operation and instant setup by removing the coupling step entirely.

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If a seal is used to ensure tight coupling between container and dosing device, then leakage is reduced, but the complexity of the device increases

Engineering Contradiction:
Improveleak preventionVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The container wall is merged with the pump housing structure, eliminating the need for separate seals and coupling mechanisms. This integration reduces device complexity while maintaining leak-free operation, as the single-piece construction removes multiple potential failure points.

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If the container and dosing device are physically separated, then the dosing device can be reused with different containers, but the cleaning time and setup time increase

Engineering Contradiction:
ImprovereusabilityVSAvoidcleaning time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The integrated container-pump unit is designed as a disposable component that is discarded after use. This eliminates the need for cleaning and complex disassembly/reassembly operations, reducing both cleaning time and setup time while maintaining versatility through replacement rather than reuse.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

4Ease of repair

If the container and dosing device are physically separated, then the dosing device can be cleaned separately, but the safety risk for technicians increases when handling hazardous viscous media

Engineering Contradiction:
Improvecleaning capabilityVSAvoidsafety risk
Core Design Contradiction:
Ease of repairVSObject-affected harmful factors

Solution Approach 1:

The integrated unit is designed as a disposable component that is discarded after use rather than cleaned and reused. This eliminates technician exposure to hazardous viscous media during cleaning operations, significantly reducing safety risks while maintaining operational effectiveness.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

5Productivity

If conventional separate container and dosing device are used, then the dosing device can be optimized for pumping function, but the probability of contact between technician and hazardous viscous medium increases

Engineering Contradiction:
Improvepumping efficiencyVSAvoidtechnician exposure risk
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The integrated container-pump unit is designed as a disposable component that encapsulates the viscous medium entirely within the container-pump assembly. This eliminates the need for technician intervention during operation, cleaning, or maintenance, completely preventing exposure to hazardous materials while maintaining pumping efficiency.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)
