Trailer with shower cubicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing trailers with shower cubicles are not optimized to accommodate the maximum number of stalls in a given area, requiring significant setup effort and internal access pathways that reduce stall density and increase setup time, especially for large events.
Innovation Solution
A trailer design with two rows of shower stalls accessible from the outside, foldable steps for height adjustment, and central water installations, allowing for efficient use of space and rapid deployment, along with flaps for weather protection and optional oil heaters for hot water supply.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If shower stalls are arranged with internal access pathways, then users can access shower stalls, but the number of shower stalls per area is reduced and setup time increases
Solution Approach 1:
Instead of providing access to shower stalls from the interior of the trailer, the patent inverts the access arrangement by providing access from the exterior. All shower stalls are accessible from outside the trailer through openings in the side walls, eliminating the need for internal access pathways and allowing the entire interior area to be used for shower stall placement.
2Ease of manufacture
If trailer width is reduced for transport, then maximum permissible width is not exceeded, but the number of shower stalls that can be accommodated is reduced
Solution Approach 1:
The patent employs dynamic side walls that can change their configuration between transport and operational states. During transport, the side walls are in a retracted position to meet width restrictions. When the trailer is deployed, the side walls extend outward to provide access to shower stalls while maintaining the full interior width for maximizing the number of stalls.
3Strength
If there is height difference between ground and shower cubicle floor, then structural integrity is maintained, but user access becomes difficult
Solution Approach 1:
The patent addresses the height difference by providing segmented access solutions in the form of steps or ramps at the entrance to each shower stall. These access elements are integrated into the side wall structure, allowing users to overcome the height difference between the ground and the shower cubicle floor while maintaining the structural integrity and waterproofing of the trailer.
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 the highest possible number of shower stalls in a trailer, facilitating rapid setup and use, accommodating large numbers of users efficiently, while minimizing setup effort and maximizing space utilization.
Implementation Method 1
For the hot water supply, an oil heater with about 250 kW heat output is preferably provided

AI summary
In order to specify a trailer with shower stalls (2, 3) that has as large a number of shower stalls as possible on the available area, it is proposed that two rows (5, 6) aligned in the direction of travel (4) of the trailer (1) Shower cubicles (2, 3) are arranged adjacent to one another and that there is access (7, 8) for the shower cubicles (2, 3) from an outside (9, 10) of the trailer (1).
