Solution Overview

Problem

Existing filling devices for chemical reactors with particulate catalyst material suffer from mechanical damage to the particles due to internal drive motors, reduced throughput, and non-uniform distribution, leading to issues like pressure loss and temperature hotspots.

Innovation Solution

A filling device with a drive unit positioned externally to the supply container, using a radial distribution unit driven by an external motor, which distributes particulate material uniformly and gently, minimizing mechanical stress and facilitating easy handling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the drive motor is arranged within the filling device, then the device structure is compact, but the particulate material is mechanically damaged by the internal motor

Engineering Contradiction:
Improvedevice structureVSAvoidmechanical damage to particulate material
Core Design Contradiction:
Device complexityVSObject-affected harmful factors

Solution Approach 1:

The drive motor is extracted from the interior of the supply container and positioned externally. This removes the harmful mechanical impact zone from the filling path, allowing particles to flow without striking internal motor components while maintaining a compact overall device structure through external motor mounting.

Inventive Principle:
Principle #2Taking out (Extraction)

2Device complexity

If the drive shaft is arranged centrally in the device, then the motor is compactly positioned, but the throughput volume is reduced by the central shaft

Engineering Contradiction:
Improvemotor positioningVSAvoidthroughput volume
Core Design Contradiction:
Device complexityVSQuantity of substance

Solution Approach 1:

The drive shaft is extracted from the central position within the supply container and repositioned externally. This eliminates the central obstruction to material flow, maximizing the throughput volume and filling rate while the motor remains compactly positioned through external mounting arrangements.

Inventive Principle:
Principle #2Taking out (Extraction)

3Adaptability or versatility

If the distributor is driven by an internal motor, then the device is self-contained, but the filling process is hindered by the internal drive components

Engineering Contradiction:
Improveself-contained deviceVSAvoidfilling process efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

An external drive unit serves as an intermediary, transmitting rotational motion to the distributor through a coupling mechanism. This allows the distributor to be driven without internal motor components that would obstruct the filling process, maintaining self-containment through the coupling while eliminating productivity hindrances.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Productivity

If the distributor rotates at high speed, then the filling rate increases, but the particulate material experiences excessive mechanical stress

Engineering Contradiction:
Improvefilling rateVSAvoidmechanical stress on particles
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The drive mechanism is extracted from the material flow path, allowing high-speed rotation of the distributor without particles striking internal components. This enables high filling rates through rapid rotation while minimizing mechanical stress on particles by eliminating impact zones.

Inventive Principle:
Principle #2Taking out (Extraction)
