Solution Overview

Problem

The existing foldable bed designs require excessive transportation space and incur high costs due to the bulky and heavy side rails, making transportation inconvenient and costly, especially for export enterprises.

Innovation Solution

A foldable bed design featuring a headboard with a receiving compartment that accommodates side rail units, a footboard, bed slats, and a bed slat support, where the side rails are composed of multiple units connected by a coupler, allowing for dismantling and storage within the headboard, reducing the overall size for transportation and enabling more beds to be transported in a single cargo container.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If the side rails are designed as unitary structures, then the structural strength is improved, but the weight and bulk increase, making transportation inconvenient

Engineering Contradiction:

Improvestructural strengthVSAvoidweight of side rails

Core Design Contradiction:

StrengthVSWeight of moving object

Solution Approach 1:

The side rails are divided into multiple segments (first side rail segment, second side rail segment, third side rail segment) that can be detached and stored within the headboard, reducing transportation weight and bulk while maintaining structural integrity when assembled

Inventive Principle:

Principle #1Segmentation

2Stability of the object's composition

If the side rails are designed as unitary structures, then the structural stability is improved, but the transportation space required increases

Engineering Contradiction:

Improvestructural stabilityVSAvoidtransportation space

Core Design Contradiction:

Stability of the object's compositionVSVolume of moving object

Solution Approach 1:

The detachable side rail segments are nested within the headboard's receiving compartment during storage and transportation, significantly reducing the volume occupied while allowing reconstruction of the complete bed structure when needed

Inventive Principle:

Principle #7Nested doll (Nesting)

3Adaptability or versatility

If the bed components are dismantled and disposed separately in a cargo container, then the assembly flexibility is improved, but the transportation space occupied increases excessively

Engineering Contradiction:

Improveassembly flexibilityVSAvoidtransportation space

Core Design Contradiction:

Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

Multiple bed components (side rail segments, footboard, bed slats, and bed slat support) are combined and stored together within the headboard's receiving compartment, merging their individual volumes into a single compact storage space and reducing overall transportation footprint

Inventive Principle:

Principle #5Merging (Combining)

AI summary

The present invention discloses a foldable bed. A first side rail and a second side rail have an end detachably connected to a headboard and an opposite end detachably connected to a footboard. A bed slat support is arranged between the first side rail and the second side rail. The headboard includes a receiving compartment formed therein. The first side rail and the second side rail each include at least two side rail units and the side rail units are connected to each other by a couple. In dismantling, the side rail units, the footboard, the bed slats, and the bed slat support are receivable and positioned in the receiving compartment. The present invention saves transportation space, reduces transportation cost, and provides a better way of weight carrying.
