Foldable bed frame

Solution Overview

Problem

Existing foldable bed frames are cumbersome and difficult to unfold and fold, with a large size when folded, making storage and transport inconvenient.

Innovation Solution

A foldable bed frame design featuring two symmetrically arranged unit bed frames hinged together, with support legs that fold perpendicular to the frame, allowing all support legs to retract inside, reducing the overall volume when folded.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the foldable bed frame uses detachable connections and multiple components for flexibility, then adaptability is improved, but device complexity increases making it difficult to unfold and fold

Engineering Contradiction:

ImproveflexibilityVSAvoidcomplexity of unfolding and folding

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The bed frame is divided into modular components including head frame, foot frame, side frames, and support legs that can be independently assembled and folded. Each component has standardized connection interfaces that simplify the assembly process while maintaining flexibility in configuration.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The support legs are designed to nest within the frame structure when folded, with the leg components fitting inside the hollow spaces of the frame members. This nesting arrangement reduces the overall folded volume and simplifies the folding process by eliminating external protrusions.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Ease of operation

If the support legs are positioned externally for easy access, then ease of operation is improved, but volume after folding increases making storage inconvenient

Engineering Contradiction:

Improveaccess to support legsVSAvoidfolded volume

Core Design Contradiction:

Ease of operationVSVolume of moving object

Solution Approach 1:

The support legs are designed to nest within the frame structure when folded, with the leg components fitting inside the hollow spaces of the frame members. This nesting arrangement reduces the overall folded volume and simplifies the folding process by eliminating external protrusions.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The support legs are positioned to fold in a direction perpendicular to the main frame folding direction. This orthogonal arrangement allows the legs to be accessed during setup but retract into the frame's depth dimension when folded, minimizing the increased dimension without compromising accessibility during assembly.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Adaptability or versatility

If the bed frame uses multiple detachable connections for flexibility, then adaptability is improved, but time required for assembly increases

Engineering Contradiction:

ImproveflexibilityVSAvoidassembly time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The bed frame is divided into modular components including head frame, foot frame, side frames, and support legs that can be independently assembled and folded. Each component has standardized connection interfaces that simplify the assembly process while maintaining flexibility in configuration.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Multiple connection functions are integrated into single composite connection pieces that simultaneously provide structural support, alignment guidance, and detachable coupling. This merging of functions reduces the number of separate fastening operations required while maintaining the flexibility of detachable connections.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A foldable bed frame comprising two symmetrically arranged unit bed frames is provided. The two unit bed frames are hinged to each other at their connection. A unit bed frame is further provided with a first plurality of support legs in hinge connection with the unit bed frame. The direction in which the plurality of first support legs fold is perpendicular to the direction in which the unit bed frame folds. Both the folding and unfolding of the foldable bed frame are very simple and convenient, and the volume after folding is small, which facilitates storage and transport.
