Split Adjustable Bed Frame for Lower Weight and Easier Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adjustable bed designs are mechanically complex, heavy, and costly, making them unsuitable for domestic furniture applications, and they are difficult to store, transport, deliver, and assemble compared to non-adjustable beds.
Innovation Solution
A modular adjustable bed design with a frame split into two sections that can be easily assembled on-site by joining the upper and lower body sections, featuring pivotally mounted adjustable backrest and leg support sections, and using simple mechanical and electrical connectors for assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If adjustable bed uses robust mechanical structure with multiple bearing members and cross-members, then structural strength and rigidity are improved, but weight and device complexity increase
Solution Approach 1:
The bed frame is divided into two separable sections (first and second sections) that can be joined together. Each section contains its own adjustable support sections with bearing members, allowing the structure to be distributed and assembled in parts rather than requiring a single heavy robust frame
Solution Approach 2:
The bearing members are designed to be pivotally mounted rather than rigidly fixed, allowing dynamic adjustment of support sections while maintaining structural integrity. This enables the structure to adapt to different positions without requiring excessive rigid reinforcement
2Strength
If adjustable bed uses complex mechanical structure with multiple bearing members and cross-members, then structural strength and rigidity are improved, but device complexity increases
Solution Approach 1:
The complex mechanical structure is segmented into two separable bed sections, each with its own simplified bearing member arrangement. This reduces the complexity of assembly and manufacturing compared to a single integrated complex structure
Solution Approach 2:
Instead of building a single complex robust structure, the invention inverts the approach by using two simpler structures that are joined together, where the complexity is distributed and reduced in each individual section
3Strength
If adjustable bed is designed as single integrated structure, then structural strength is improved, but ease of manufacture, storage, and assembly deteriorates
Solution Approach 1:
The bed is segmented into two manufacture-ready sections that can be produced separately and joined on-site. This improves ease of manufacture, storage, and assembly while maintaining structural strength through the joining mechanism
Solution Approach 2:
The bearing members and support sections are pre-assembled into the two main bed sections during manufacturing, so that the complex mechanical components are already in place before delivery. This preliminary assembly simplifies the final on-site assembly process

AI summary
The invention concerns an adjustable bed comprising a frame and at least one adjustable body support section including an adjustable backrest support section pivotally mounted for angular adjustment with respect to the frame. The frame comprises at least two sections including an upper body section on which the back rest is mounted and a separate lower body section. The upper and lower body sections are capable of being joined together to provide a full length adjustable bed. The invention provides an adjustable bed that can be stored and transported in two parts (plus mattress), which provides for ease of storage, display, delivery and installation.
