Solution Overview

Problem

Traditional folding beds, especially Murphy bed chests, are heavy, cumbersome to move, and offer limited storage or access to storage when in the opened position, making them inefficient for space utilization.

Innovation Solution

A folding bed chest system with a chest assembly, primary hinges for the front panel, secondary hinges for the footboard frame, and a freely movable drawer assembly with wheels, along with magnetic retainers and a latch assembly to facilitate easy conversion between closed and opened positions, and optional features like a shelf and charging station for enhanced functionality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If the Murphy bed chest is constructed with solid panels and frame, then structural strength is improved, but weight increases making it cumbersome to move

Engineering Contradiction:
Improvestructural strengthVSAvoidweight
Core Design Contradiction:
StrengthVSWeight of moving object

Solution Approach 1:

The bed structure is divided into separate components including the frame, mattress, and storage drawers that can be independently assembled and moved. This segmentation allows the overall structure to be strengthened through proper joint design while individual components remain manageable in weight for easier assembly and repositioning.

Inventive Principle:
Principle #1Segmentation

2Stability of the object's composition

If the bed is designed as a fixed cabinet structure, then stability is improved, but ease of movement between closed and opened positions deteriorates

Engineering Contradiction:
ImprovestabilityVSAvoidease of movement between positions
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The cabinet incorporates hinge mechanisms that enable dynamic movement between closed and opened positions. The front panel assembly is connected to the main frame through hinges allowing it to pivot between a closed cabinet configuration and an opened bed configuration, providing both stability when closed and ease of transformation when needed.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

Hinge mechanisms serve as intermediary elements between the fixed frame structure and the movable front panel assembly. These hinges act as mediators that allow controlled movement while maintaining structural integrity, enabling smooth transition between positions without compromising the overall stability of the cabinet frame.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Volume of moving object

If storage space is enclosed within the cabinet structure, then space utilization is improved, but access to storage deteriorates when bed is opened

Engineering Contradiction:
Improvestorage spaceVSAvoidaccess to storage
Core Design Contradiction:
Volume of moving objectVSEase of operation

Solution Approach 1:

The storage system is segmented into multiple independent drawers that can be accessed individually. These drawers are positioned within the cabinet structure but are designed to slide out independently, allowing users to access stored items even when the bed is in the opened position, thus maintaining both space utilization and accessibility.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The cabinet structure serves multiple functions: it provides enclosed storage space when closed, transforms into a bed when opened, and maintains accessible storage drawers throughout both configurations. The drawer assembly acts as a universal element that fulfills storage needs regardless of whether the bed is in closed or opened position.

Inventive Principle:
Principle #6Universality (Multi-functionality)

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

Improves the ease of movement and provides better storage access and utilization of space when the bed is in the opened position, addressing the limitations of traditional Murphy bed chests.

Implementation Method 1

one or more retainers retain the footboard leg at the footboard frame when the front panel assembly is in the closed position. the one or more retainers are one or more magnets.

Methodology Applied
Scientific EffectMagnetism: Magnetism

AI summary

A folding bed chest system includes a cabinet having a front panel assembly movable from a closed position to an opened position, wherein when in the open position the front panel assembly is supportive of a mattress located thereon. A drawer assembly is freely movable into an out of a drawer opening located below the front panel assembly. The drawer assembly is configured such that the front panel assembly is movable from the closed position to the opened position when the drawer assembly is located fully in the drawer opening.
