Pivotable Rear Sleeping Unit for Mobile Home Space Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile homes face challenges in optimizing space usage for bed furniture, as reclining elements like beds take up significant space when retracted and require extensive storage, compromising interior space efficiency.
Innovation Solution
A mobile home design featuring a sliding pull-out element at the rear with pivotable bed parts that align at an angle in the driving position, allowing the bed to fold compactly and extend flush for optimal space utilization, including a flexible mattress and insulating walls, and a storage compartment accessible from outside.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a bed is fixed in a flat sleeping position within the vehicle interior, then sleeping comfort is improved, but interior space is significantly reduced
Solution Approach 1:
The bed is designed with pivotable parts that can change position between a flat sleeping position and an angled storage position. This dynamic configuration allows the bed to provide full sleeping comfort when needed while minimizing space occupation during vehicle operation or when not in use.
Solution Approach 2:
The bed is divided into multiple pivotable parts (at least two parts) that can be independently positioned. This segmentation enables the bed to be folded into a compact configuration with reduced spatial requirements while maintaining the ability to form a complete sleeping surface when required.
2Ease of operation
If a bed is designed to extend across the entire inner width of the vehicle, then sleeping comfort is improved, but space utilization in driving position becomes inefficient
Solution Approach 1:
The bed incorporates pivotable parts that enable dynamic reconfiguration between a wide extended position for sleeping comfort and a compact folded position for efficient space utilization during vehicle operation.
Solution Approach 2:
The bed transitions from a two-dimensional flat surface when extended to a three-dimensional compact form when folded, utilizing vertical space and angular positioning to reduce the horizontal footprint while maintaining the full sleeping surface area when needed.

AI summary
A motorhome (1) comprises a vehicle interior enclosed by side walls (4), a rear (5), a floor, and a ceiling, wherein a sliding pull-out element (6) is provided at the rear (5), which can be moved from a driving position to a rearward-projecting pull-out position, wherein a sleeping unit (20) is fixed in the pull-out element (6), which has at least two parts (21, 22) that can be pivoted relative to each other, which form a sleeping surface in the pull-out position and are oriented at an angle to each other in the driving position. This allows the interior space to be used optimally with the sleeping unit (20).
