Solution Overview

Problem

Existing base cabinets for vivariums, particularly aquariums, lack a visually appealing and easy-to-use passage for power and water supply/drainage lines, often requiring additional fittings and obstructing cable passages.

Innovation Solution

A base cabinet with side walls featuring recesses and magnetic closure elements that allow for easy insertion and removal of panel elements, eliminating the need for additional fittings and ensuring a flush, visually appealing design.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional mechanical fittings and hinges are used to close the recess, then the panel element is securely fixed, but the cable passage becomes obstructed and the appearance is compromised

Engineering Contradiction:
Improvesecure fixation of panel elementVSAvoidadditional fittings obstructing cable passage
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The invention extracts and removes traditional mechanical fittings (hinges, stops, screws) from the recess area. Instead, magnetic closure elements are mounted on the outer surface of the side wall, completely clear of the recess opening. This extraction eliminates obstructions to cable passage while maintaining secure panel fixation through magnetic attraction between the closure elements and the panel.

Inventive Principle:
Principle #2Taking out (Extraction)

2Ease of operation

If additional fittings such as hinges and limiting stops are provided, then the panel element is securely fixed, but the construction becomes more complex and the appearance is less appealing

Engineering Contradiction:
Improvesecure panel fixationVSAvoidnumber of fittings required
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The invention merges multiple functions into the magnetic closure elements: they provide both the securing force (replacing hinges and stops) and the centering function (replacing alignment mechanisms). The magnetic field simultaneously achieves fixation, centering, and clean appearance, reducing the overall number of components needed while improving ease of operation through simple magnetic attachment and removal.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of manufacture

If the recess is left completely open for cable access, then cable passage is easy, but the visual appearance is compromised

Engineering Contradiction:
Improvecable accessVSAvoidvisual appearance of cabinet
Core Design Contradiction:
Ease of manufactureVSShape

Solution Approach 1:

The panel element acts as an intermediary component that can be inserted into the recess to provide a clean visual appearance when cable access is not needed. The magnetic closure elements enable this panel to be easily attached and removed without permanent modifications, allowing the cabinet to transition between an enclosed aesthetic appearance and an open cable access state.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Reliability

If traditional mechanical fastening methods are used, then the panel is securely fixed, but tool-free installation and removal is not possible

Engineering Contradiction:
Improvepanel fixation strengthVSAvoidtool-free installation
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The invention replaces traditional mechanical fastening systems (screws, clips, hinges requiring tools) with a magnetic field-based fastening system. The magnetic closure elements generate sufficient holding force to securely fix the panel while allowing tool-free installation and removal through simple magnetic attraction and detachment, eliminating the need for screwdrivers, clips, or other installation tools.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

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

Enables a clean, visually appealing, and easy-to-use passage for cables and tools, with improved usability and stability, while maintaining a seamless appearance.

Implementation Method 1

the panel element is held exclusively by magnetic forces acting between the first magnetic closure element and the second magnetic closure element

Methodology Applied
Scientific EffectMagnetic force: Magnetism

Implementation Method 2

the first magnetic element to be positioned adjacent to the recess. At the same time, the magnetic forces within the recess allow for easy centering of the panel element

Methodology Applied
Scientific EffectMagnetic interaction: Magnetism
