Solution Overview

Problem

Existing suction material collection stations face challenges in disposing of suction material without contaminating the ambient air and minimizing noise pollution caused by the blower, as they often require mechanisms for dust-tight connections and noise reduction during filter chamber emptying.

Innovation Solution

The suction material collection station is designed with a receiving space that completely surrounds the filter chamber, equipped with a feed device to transfer the filter chamber from the suction cleaning device, allowing for dust-free and low-noise operation. The feed device includes a guide and drive mechanism for automated displacement, and the receiving space is positioned above the collection container to utilize gravity for material transfer, with optional air flow channels and pressure sensors to optimize suction power.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If the filter chamber is completely transferred into the suction material collection station, then dust-free operation is improved, but the device complexity increases

Engineering Contradiction:
Improvedust contaminationVSAvoidtransfer mechanism complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The filter chamber is completely nested within the suction material collection station during the transfer process. The receiving space is designed to completely surround the filter chamber, creating a nested configuration that ensures dust-free operation while managing the complexity through integrated design

Inventive Principle:
Principle #7Nested doll (Nesting)

2Productivity

If the blower is operated in the suction material collection station for emptying the filter chamber, then productivity is improved, but noise pollution increases

Engineering Contradiction:
Improvefilter chamber emptying efficiencyVSAvoidnoise pollution
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

The blower is extracted from the suction cleaning device and relocated to the suction material collection station. This allows the blower to operate in a controlled environment where noise can be better managed, while maintaining high productivity for emptying the filter chamber

Inventive Principle:
Principle #2Taking out (Extraction)

3Object-affected harmful factors

If the receiving space completely surrounds the filter chamber, then dust-free transfer is improved, but the volume of the collection station increases

Engineering Contradiction:
Improvesuction material leakageVSAvoidcollection station volume
Core Design Contradiction:
Object-affected harmful factorsVSVolume of stationary object

Solution Approach 1:

The receiving space is designed to completely surround the filter chamber in a nested configuration, ensuring that suction material cannot escape during transfer. This complete enclosure prevents leakage while the nested design optimizes the use of internal volume

Inventive Principle:
Principle #7Nested doll (Nesting)

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

This configuration ensures a dust-free and quiet transfer of suction material, reducing noise emissions and eliminating the need for additional mechanisms in the suction cleaning device, while allowing for efficient and controlled regeneration of the filter chamber.

Implementation Method 1

The receiving space is arranged above the suction material collection container in relation to a usual usage orientation of the suction material collection station, so that suction material can fall, following gravity, from a filter chamber arranged in the receiving space into the suction material collection container
