Solution Overview

Problem

Conventional bed frames are heavy and inconvenient for transportation due to their fixed structure and materials.

Innovation Solution

A lightweight modular bed design featuring a front and rear base frame with support units, linkage units, and stretchable supporting webs that allow for easy assembly and disassembly, reducing weight and enhancing mobility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If a conventional fixed bed frame structure is used, then structural stability is improved, but weight increases and transportation convenience deteriorates

Engineering Contradiction:

Improvestructural stabilityVSAvoidbed frame weight

Core Design Contradiction:

Stability of the object's compositionVSWeight of moving object

Solution Approach 1:

The bed frame is divided into multiple modular components including head section, foot section, and intermediate sections that can be detached and reconfigured. This segmentation reduces the weight of individual components and enables easy disassembly for transportation while maintaining structural stability when assembled.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The bed frame incorporates movable and adjustable components that allow dynamic reconfiguration between different configurations (e.g., single bed, double bed, loft bed). This dynamic design replaces fixed heavy structures with adaptable lightweight components.

Inventive Principle:

Principle #15Dynamics

2Strength

If a conventional fixed bed frame structure is used, then structural integrity is improved, but ease of assembly and disassembly deteriorates

Engineering Contradiction:

Improvestructural integrityVSAvoidease of assembly and disassembly

Core Design Contradiction:

StrengthVSEase of operation

Solution Approach 1:

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The modular components are designed to nest within each other during storage and transportation, with smaller sections fitting into larger sections. This nesting arrangement simplifies assembly and disassembly operations while preserving structural integrity.

Inventive Principle:

Principle #7Nested doll (Nesting)

AI summary

A lightweight modular bed includes a front base frame, a rear base frame, a front support frame unit mounted on the frame base frame, a rear support frame unit mounted on the rear base frame, a first front linkage unit with a first front retaining member, a second front retaining member, a first rear linkage unit with a first rear retaining member, a second rear retaining member, a front supporting web which has two lateral portions retained by the first and second front retaining members, and a rear support web which has two lateral portions retained by the first and second rear retaining members. When each of the first front and rear retaining members is displaced to a stretching position, a corresponding one of front and rear support webs is fully stretched.
