Removable Utilities Pod for Caravan Space Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Caravans and similar vehicles face space constraints for utilities apparatus, which are typically housed inside the cabin, necessitating a solution to optimize space usage while maintaining accessibility and functionality.
Innovation Solution
A utilities pod is designed to be mounted underneath the cabin structure, containing multiple utilities apparatus and featuring an interface unit with ports for connecting services to the cabin, allowing for flexible conduit connections that enable the pod to be removed without disconnecting conduits, and includes features like removable lids and drawers for convenient servicing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If utilities apparatus are provided inside the cabin structure, then accessibility and functionality are maintained, but cabin space is consumed
Solution Approach 1:
The patent extracts the utilities apparatus from the cabin interior and relocates them to an external pod mounted on the vehicle chassis. This extraction resolves the space conflict by removing the apparatus from the cabin volume while maintaining their functionality through the interface unit that provides service connections between the pod and cabin.
Solution Approach 2:
The invention transitions the utilities apparatus from a two-dimensional interior space arrangement to a three-dimensional external configuration. The pod is mounted externally on the chassis, utilizing vertical and lateral space outside the cabin envelope, thereby freeing up cabin volume while maintaining service accessibility through protruding interface ports.
2Volume of moving object
If utilities apparatus are relocated to an external pod, then cabin space is saved, but servicing accessibility may be compromised
Solution Approach 1:
The interface unit serves as an intermediary between the external pod and the cabin interior. It provides accessible ports that protrude from the cabin structure, allowing service engineers to connect and service the utilities apparatus without needing to access the interior of the pod or dismantle components. This mediator maintains ease of repair while enabling external relocation.
Solution Approach 2:
The interface unit is pre-configured with connection ports that align with the cabin service points before the pod is installed. This preliminary arrangement ensures that servicing can be performed easily from the exterior, eliminating the need for complex disassembly operations and maintaining repair accessibility despite the external relocation of apparatus.
3Strength
If the pod is rigidly connected to the cabin structure, then structural support is provided, but flexibility for removal and maintenance is reduced
Solution Approach 1:
The mounting system transitions from a static rigid connection to a dynamic removable connection. The pod is designed with mounting interfaces that allow it to be securely attached to the chassis when in use, providing structural support, yet can be easily detached when maintenance or relocation is required. This dynamic mounting resolves the contradiction between strength and adaptability.

AI summary
A utilities pod (10) for a vehicle, especially a caravan. The pod is removably mounted underneath the cabin structure and contains utilities apparatus such as a water heater, space heater (62), battery and water tank (60). The pod is connected to the cabin of the vehicle by an interface unit having multiple ports (18) by which said respective utility services are provided to the cabin. The interface unit is configured for installation in the floor of said cabin such that the ports are exposed to the interior of the cabin structure.
