Solution Overview

Problem

Existing aquarium filtration systems often face challenges in controlling water flow effectively and integrating vibration and noise reduction, with components being difficult to operate and not always part of the filter device.

Innovation Solution

A filter arrangement that includes a housing assembly, pump assembly, transfer tube assembly, and valve assembly, where the transfer tube assembly is formed from bonded tube halves with a rotatable valve body and operator, and dampening structures are used to reduce vibration and noise transmission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a control valve is added to the filter device, then water flow control capability is improved, but device complexity increases

Engineering Contradiction:
Improvewater flow control capabilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The valve assembly is integrated into the filter device housing, combining the valve mechanism with the existing filter structure. The valve body is positioned within the housing and the operator extends through the housing wall, merging multiple functions (filtration and flow control) into a single integrated device rather than separate components

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The filter device housing serves multiple functions: it contains the filter medium, houses the valve mechanism, provides structural support, and allows user interaction through the operator. This multi-functionality reduces the need for separate control devices while maintaining ease of operation

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

2Ease of operation

If the valve operator extends through the housing wall, then ease of operation is improved, but device complexity increases

Engineering Contradiction:
Improveease of operationVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The valve operator is extracted from the internal valve mechanism and extended through the housing wall to the external environment. This allows users to operate the valve without disassembling or accessing the internal components of the filter device, significantly improving ease of operation while the operator itself remains a relatively simple structural element

Inventive Principle:
Principle #2Taking out (Extraction)

3Object-affected harmful factors

If dampening structures are added to reduce vibration and noise, then harmful factors are reduced, but device complexity increases

Engineering Contradiction:
Improvevibration and noiseVSAvoiddevice complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The dampening structures convert the harmful vibrations and noises generated by the pump into absorbed energy through viscoelastic materials. The pump housing and/or mounting structures incorporate materials or designs that dissipate vibrational energy, transforming the harmful mechanical vibrations into heat energy that is safely dissipated

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

AI summary

A filter arrangement for an aquarium is disclosed. The filter arrangement can include a housing assembly, a pump assembly, a transfer tube assembly, and a valve assembly for controlling water flow through the transfer tube assembly. The transfer tube assembly can include a tube structure within which a valve body of the valve assembly is rotatably disposed. The tube structure can be formed from a first tube half mated to a second tube half to permanently secure the valve body within the tube structure. A valve operator can be connected to the valve body to advantageously allow a user to manipulate the flow of water through the transfer tube assembly. Control of water flow through the filter arrangement is beneficial for obtaining a desired water flow for a certain aquarium size and application and for reducing flow during certain periods, such as during feeding.
