Solution Overview

Problem

Existing reptile caging systems, particularly vertical rack systems, face challenges in efficiently managing temperature and humidity levels required by reptiles, which are often higher than those comfortable for human owners, and there is a need for a more efficient and cost-effective solution that minimizes space usage and maintenance complexity.

Innovation Solution

A modular rack system comprising multiple levels with removable tubs, where each level is supported by a frame with polymer injection-molded components such as glides, joint connectors, and top panels, allowing for easy assembly and disassembly, reduced shipping weight, and customizable tub arrangements to accommodate varying animal needs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If traditional welded stainless steel support structures are used, then structural strength and durability are improved, but manufacturing complexity and assembly time increase

Engineering Contradiction:
Improvestructural strengthVSAvoidmanufacturing complexity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The support structure is divided into modular components including frame members, cross members, and pre-assembled units that can be manufactured separately and then connected through simple joining mechanisms rather than requiring complex welding operations. This segmentation allows each component to be optimized independently while simplifying overall manufacturing and assembly.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The welding process is extracted and removed from the assembly process. Instead of welding components together, the design uses mechanical connection methods such as friction-fit joints, snap-fit connections, or simple fasteners, eliminating the need for specialized welding equipment and skilled welders while maintaining structural integrity.

Inventive Principle:
Principle #2Taking out (Extraction)

2Volume of moving object

If vertical rack systems with removable tubs are used, then space utilization is improved, but temperature and humidity control complexity increases

Engineering Contradiction:
Improvespace utilizationVSAvoidenvironmental control complexity
Core Design Contradiction:
Volume of moving objectVSDevice complexity

Solution Approach 1:

Multiple environmental control functions are merged into integrated heating and humidity control units that can manage temperature and moisture levels across multiple tubs simultaneously. This consolidation reduces the number of separate control systems needed while maintaining precise environmental conditions for different reptile species.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The rack system employs universal heating elements and humidity control mechanisms that can serve multiple tubs with different environmental requirements. The system can be configured to provide zone-based environmental control where a single control unit manages conditions across several compartments, simplifying the overall system while maintaining versatility.

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

3Stability of the object's composition

If integral lid support structures are used, then structural stability is improved, but adaptability and ease of maintenance decrease

Engineering Contradiction:
Improvestructural stabilityVSAvoidadaptability
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The lid support structure is segmented into detachable components that can be independently accessed, removed, or replaced. This allows maintenance personnel to service specific parts without disassembling the entire structure, improving maintainability while preserving overall structural stability through modular design.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The support structure incorporates dynamic elements such as adjustable shelves, movable dividers, or reconfigurable framing that can be modified to accommodate different tub sizes and configurations. This dynamic capability maintains structural integrity while providing adaptability for various enclosure requirements and future upgrades.

Inventive Principle:
Principle #15Dynamics

AI summary

A rack for animal cages may comprise multiple levels stacked together in a vertical orientation, each level acts as a frame configured to support one or more tubs that serve as cages. An example rack for animal cages comprises a first enclosure, a first top panel, and two glides. The first enclosure having a floor, four exterior sidewalls, and a lip extending outwardly from a top surface of at least two of the four exterior sidewalls. Each of the two glides comprises a first longitudinal groove configured to receive an edge portion of the first top panel therein and a second longitudinal groove configured to removably receive a portion of the lip extending outwardly from the top surface of the first enclosure. The two glides are positioned to support the first top panel and the first enclosure therebetween, and configured to position the first top panel so that it covers the first enclosure when it is positioned therebetween.
