Solution Overview

Problem

Existing bed configurations in Recreation Vehicles (RTVs) are limited in size and lack a simple, efficient method for expanding the bed space while maintaining storage capacity.

Innovation Solution

A fold-up bed conversion system that includes a bed section and a bench section, where the bench section can be folded up and integrated with the bed section to increase the bed size, while also providing additional storage space.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of moving object

If a bench with ottomans and filler material is used to expand the bed, then the bed size is increased, but the number of seams between cushions increases and storage space is reduced

Engineering Contradiction:

Improvebed sizeVSAvoidnumber of seams between cushions

Core Design Contradiction:

Area of moving objectVSDevice complexity

Solution Approach 1:

The patent merges the ottoman and filler material into a single integrated bench structure. The bench includes a seat portion and leg portions that fold down to form the expanded bed surface, eliminating the need for separate filler materials and multiple cushion assemblies. This integration reduces the number of seams and simplifies the overall structure while maintaining the bed expansion functionality.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The bench structure serves multiple functions: it provides seating during the day, expands to form part of the bed surface at night, and includes storage compartments for when the bed is not in use. This multi-functionality eliminates the need for separate filler materials that would require storage space, as the bench itself becomes the functional element in both configurations.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Area of moving object

If a bench with ottomans and filler material is used to expand the bed, then the bed size is increased, but storage space is reduced

Engineering Contradiction:

Improvebed sizeVSAvoidstorage space

Core Design Contradiction:

Area of moving objectVSArea of stationary object

Solution Approach 1:

The bench is designed with movable, foldable leg portions that can be positioned in different configurations. When the bed needs to be expanded, the leg portions fold down to create the additional bed surface. When the bed is not in use, the leg portions can be folded up or removed, freeing up storage space. This dynamic design allows the same structure to serve different functions without permanently occupying storage space.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent design allows the bench components (particularly the leg portions) to be easily detached or folded away when not needed for bed expansion. This enables the recovery of storage space when the bed expansion function is not required, while still providing the full bed expansion capability when needed. The structure can be configured and reconfigured as needed without permanent structural changes.

Inventive Principle:

Principle #34Discarding and recovering

AI summary

A fold-up bedding conversion system enables the creation of a larger sized bed that may be used in limited space situations, where the conversion system includes a frame that includes a substantial portion of the bed and a bench, positioned at a proximal end of the bed, that is rotational movable to enable the back section of the bench to be positioned substantially in-line with the bed.
