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

VSEngineering 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

Engineering Contradiction:
Improvesleeping comfortVSAvoidinterior space
Core Design Contradiction:
Ease of operationVSArea of stationary object

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.

Inventive Principle:
Principle #15Dynamics

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.

Inventive Principle:
Principle #1Segmentation

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

Engineering Contradiction:
Improvesleeping comfortVSAvoidstorage space requirement
Core Design Contradiction:
Ease of operationVSVolume of moving object

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.

Inventive Principle:
Principle #15Dynamics

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.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

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).
