Pet Transport Box L-Shaped Edge Projections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pet transport boxes face challenges with costly and unreliable closure mechanisms, making them difficult to repair and maintain due to unavailability of spare parts, leading to premature disposal.
Innovation Solution
The use of 'L'-shaped projections on the edges of the half-shells for reversible locking, combined with a rotating hook and pin system with a knob for easy assembly and disassembly, provides a cost-effective and reliable method for fixing the two halves together.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex closure mechanisms (tabs, hinged elements, pins) are used to securely fix the two half-shells, then the reliability of the fixing is improved, but the manufacturing cost increases and the device complexity increases
Solution Approach 1:
The closure mechanism is segmented into multiple identical fixing elements distributed along the joint between half-shells. Each element consists of a projection with an L-shaped cross-section that independently provides fixing, allowing the system to achieve high reliability through distribution rather than relying on a single complex mechanism. This segmentation enables use of simple, cheap individual elements while maintaining overall system reliability.
Solution Approach 2:
Instead of using complex active mechanisms (hinged tabs, spring-loaded pins) that require moving parts and assembly operations, the invention inverts the approach by using passive geometric interlocking. The L-shaped projections create automatic mechanical engagement through their geometry alone, where the horizontal side engages with the vertical side of the opposing half-shell, eliminating the need for complex closure mechanisms.
2Reliability
If complex closure mechanisms are used to ensure secure fixing, then the reliability is improved, but the ease of operation deteriorates due to difficulty in assembly and disassembly
Solution Approach 1:
The invention replaces complex active closure mechanisms with passive geometric interlocking. The L-shaped projections engage automatically when half-shells are brought together, and disengagement is achieved by simple separation motion. This inversion from active to passive mechanism dramatically simplifies operation while maintaining reliability through the distributed nature of multiple fixing elements.
Solution Approach 2:
The closure mechanism is self-servicing through automatic geometric engagement. When the two half-shells are brought into contact, the L-shaped projections automatically engage with their complementary geometry without requiring user manipulation of complex mechanisms. The system serves itself by using the inherent geometry of the projections to create secure fixing upon simple contact.
3Reliability
If complex closure mechanisms with multiple parts are used, then the reliability of fixing is improved, but the ease of repair deteriorates due to unavailability of spare parts
Solution Approach 1:
The fixing system is segmented into multiple identical, simple projection elements distributed along the joint. This segmentation means that if one projection fails, the other projections continue to provide fixing, maintaining system reliability. Additionally, the simplicity and identical nature of each projection element makes them trivial to manufacture as spare parts, greatly improving ease of repair compared to complex closure mechanisms with unique, proprietary components.
Solution Approach 2:
The invention uses multiple identical copies of the L-shaped projection element along the joint. This copying approach ensures that spare parts can be easily manufactured as simple geometric replicas without requiring specialized tooling or proprietary manufacturing processes. The simplicity of the copied geometry makes spare parts availability trivial, resolving the repairability issue.
4Ease of manufacture
If simple and cost-effective closing means are used, then the manufacturing cost is reduced, but the reliability and safety deteriorate
Solution Approach 1:
The invention segments the fixing function into multiple simple projection elements distributed along the joint. Each individual projection is simple and cheap to manufacture, but the collective system achieves high reliability through distribution. This segmentation allows use of inexpensive geometric features (projections with L-shaped cross-sections) while the multiplicity of elements provides redundancy and robust fixing.
Solution Approach 2:
The invention merges multiple simple fixing elements into a unified closure system. By combining several identical L-shaped projections along the joint, the system achieves cumulative fixing strength and reliability that exceeds what a single complex mechanism could provide, while maintaining simplicity and low manufacturing cost for each individual element.

AI summary
The present invention concerns a transport box for pets, of the type comprising two half-shells (1, 2) having substantially identical shape and sizes, to be overlappingly arranged, so that the respective concavities face one another. The half-shells form the two halves of the transport box, arranged symmetrically with respect to the horizontal middle plane thereof. It is particularly foreseen for the transport box, with the two overlapping half-shells, to have an opening that can be closed by means of a door, a grate (3) or similar. The transport box according to the model is characterised by the particular configuration of the means which allow the two half-shells to be reversibly fixed together (fig.1).
