Solution Overview

Problem

Existing suction bag emptying devices require the use of cleaning agents, which can be inconvenient and wasteful, as they often necessitate separate supply systems and may not be used efficiently during the cleaning process.

Innovation Solution

An accessory part featuring a lid with a capsule containing a cleaning agent, such as liquid, gel, or disinfectant, that is designed to be easily integrated into the emptying device, allowing for non-contact dispensing and prolonged use of the cleaning agent through a throttled flow mechanism, ensuring uniform distribution during the emptying process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a separate cleaning agent supply system is constructed for the emptying device, then the cleaning function is improved, but the device complexity increases

Engineering Contradiction:
Improvecleaning functionVSAvoidcleaning agent supply system
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The cleaning agent container is integrated into the lid structure of the emptying device, combining the cleaning function with the existing lid component. This eliminates the need for a separate cleaning agent supply system while maintaining effective cleaning capability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The lid serves dual functions: it closes the emptying device container and houses the cleaning agent container. This multi-functionality approach allows the same component to perform both containment and cleaning delivery roles.

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

2Ease of operation

If cleaning agent is dispensed freely during the cleaning process, then the cleaning coverage is improved, but the loss of substance increases

Engineering Contradiction:
Improvecleaning coverageVSAvoidcleaning agent
Core Design Contradiction:
Ease of operationVSLoss of substance

Solution Approach 1:

The plug is designed with specific geometric parameters (height, diameter, positioning) to control the gap size between itself and the container bottom. This parameter optimization throttles the liquid flow rate, ensuring adequate cleaning coverage while minimizing cleaning agent consumption.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The plug acts as an intermediary element between the cleaning agent reservoir and the discharge point. It mediates the flow of liquid cleaning agent, creating a controlled throttling effect that balances cleaning effectiveness with substance conservation.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If the cleaning agent flows quickly through the system, then the cleaning speed is improved, but the duration of action decreases

Engineering Contradiction:
Improvecleaning speedVSAvoidcleaning agent usage duration
Core Design Contradiction:
ProductivityVSDuration of action of moving object

Solution Approach 1:

By adjusting the gap dimensions between the plug and container bottom, the system achieves an optimal balance between flow rate and duration. The throttled flow extends the cleaning agent's action duration while maintaining sufficient cleaning speed through the continuous flow mechanism.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The system maintains continuous flow of cleaning agent through the throttled gap, ensuring uninterrupted cleaning action throughout the emptying process. This continuous delivery extends the effective duration of the cleaning agent compared to intermittent or rapid discharge systems.

Inventive Principle:
Principle #20Continuity of useful action

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The solution enables easy and efficient cleaning of suction bag emptying devices without the need for separate cleaning agent supply systems, prolongs the usage of cleaning agents, and ensures thorough cleaning by uniformly mixing the agent with the flow, thereby enhancing the cleaning process.

Implementation Method 1

The container is closed with a plug, the plug being pressed near the bottom of the container, which results in the liquid level rising in a circular area in the container around the plug

Methodology Applied
Scientific EffectFluid displacement: Archimedes' Principle (Buoyancy)

Implementation Method 2

At the bottom of the container, in the area remaining under the plug, there may be ridges extending radially from the middle of the container towards the edges and ensuring that the plug cannot get too deep but that the gap is always open

Methodology Applied
Scientific EffectMechanical constraint: Mechanical Force

Implementation Method 3

the gap between the plug and the bottom of the container throttles the flow to be suitably small

Methodology Applied
Scientific EffectFlow throttling: Pressure Drop

Implementation Method 4

The capsule is broken and the liquid agent begins to flow along the cylinder and its conical head, reaching, at the conical head, openings from where water or other liquid or gas is flowing. The liquid agent is mixed into the flow arriving from the openings and becomes thus uniformly dispensed into the flow.

Methodology Applied
Scientific EffectFluid mixing: Turbulence
