Solution Overview

Problem

Conventional contaminated fluid recovery apparatuses have complex drive systems and are bulky due to the parallel orientation of the filter drum relative to the conveyor, leading to increased load on the filter drum from large chips entering the inlet port.

Innovation Solution

The filter drum is rotated by the conveyor's chain, simplifying the drive system and orienting it perpendicular to the conveyor, with inlet ports positioned transversely and distant from the contaminated fluid supply port to prevent large chips from entering, using an idler sprocket for motion transmission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the filter drum member is located parallel to the direction of travel of the conveyor, then the drive system can be independent, but the apparatus becomes larger and more complex

Engineering Contradiction:
Improvedrive system independenceVSAvoiddrive system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The filter drum member is repositioned to be driven by the conveyor's chain mechanism, merging the drive function into the existing conveyor system. This eliminates the need for a separate drive mechanism for the filter drum, simplifying the overall drive system while maintaining operational reliability

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The conveyor chain is given a dual function: it both transports the conveyor belt and drives the filter drum member. This multi-functional use of the chain mechanism reduces the number of dedicated drive components needed in the system

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

2Reliability

If the filter drum member is located parallel to the direction of travel of the conveyor, then the drive system can be independent, but the apparatus becomes larger

Engineering Contradiction:
Improvedrive system independenceVSAvoidapparatus size
Core Design Contradiction:
ReliabilityVSVolume of moving object

Solution Approach 1:

The filter drum member is repositioned to be driven by the conveyor's chain mechanism, merging the drive function into the existing conveyor system. This eliminates the need for a separate drive mechanism for the filter drum, simplifying the overall drive system while maintaining operational reliability

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The filter drum member is reoriented from a parallel arrangement to a perpendicular arrangement relative to the conveyor's direction of travel. This dimensional change allows the inlet port to be positioned away from the supply port, compacting the apparatus footprint

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Device complexity

If the inlet port is transversely elongated in the direction of travel of the conveyor, then the filter drum can be positioned parallel to the conveyor, but large chips get into the inlet port increasing the load on the filter drum

Engineering Contradiction:
Improvedrive system simplicityVSAvoidchip contamination of inlet port
Core Design Contradiction:
Device complexityVSObject-affected harmful factors

Solution Approach 1:

The filter drum member is reoriented from a parallel arrangement to a perpendicular arrangement relative to the conveyor's direction of travel. This dimensional change allows the inlet port to be positioned away from the supply port, preventing large chips from entering while maintaining a simple drive system

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The inlet port is positioned asymmetrically relative to the supply port, creating a spatial separation that prevents direct flow of large chips into the filter drum. This asymmetric positioning resolves the contradiction between simple drive system and chip contamination prevention

Inventive Principle:
Principle #4Asymmetry

AI summary

A contaminated fluid recovery apparatus (10) includes a dirty tank (20), a conveyor (30), and a drum-shaped filter unit (21). Inlet ports (60, 61) of the drum-shaped filter unit (21) open along an axis (X) of a magnet drum (40). The conveyor (30) scrapes out an object for removal (S) settled on a bottom portion (20a) of the dirty tank (20) toward an exit section (27). The conveyor (30) includes a lower portion (30a) which moves along the bottom portion (20a) and an upper portion (30b) which passes over the lower portion (30a). The magnet drum (40) is located horizontally between the lower portion (30a) and the upper portion (30b) of the conveyor (30) so that its axis (X) is perpendicular to a direction of travel (F) of the conveyor (30). The magnet drum (40) is driven by a chain (33) of the conveyor (30).
