Modular Adjustable Bed Frame with Segmented Coupling for Easy Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional beds are complicated to assemble and require pre-assembly in factories, making them cumbersome for transportation and inconvenient for users to assemble at home.
Innovation Solution
A modular bed design featuring a bed frame unit and middle coupler unit, with adjustable components such as sliding frames, head support frames, and leg support frames, allowing for easy assembly and adjustment by users, including the use of interlocking grooves and tracks, and coupler members for alignment and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the bed is assembled in advance in the factory, then the structural integrity and stability are improved, but the transportation convenience and assembly ease deteriorate
Solution Approach 1:
The bed is divided into multiple modular components including head section, foot section, middle section, and side rails that can be separately manufactured and transported. These segments are designed with standardized coupling mechanisms that enable easy assembly by users while maintaining structural integrity through precise alignment features and secure connection points
2Reliability
If the bed is assembled in advance in the factory, then the structural integrity is improved, but the transportation convenience deteriorates
Solution Approach 1:
The bed frame is segmented into collapsible components that can be disassembled into compact units for efficient transportation. The side rails and support sections can be nested or folded to reduce overall length and volume during shipping, while maintaining full structural integrity when assembled at the destination
3Ease of operation
If modular components are used, then the assembly ease and customization are improved, but the device complexity increases
Solution Approach 1:
Standardized coupling mechanisms and universal connection interfaces are implemented across all modular components. The same coupling system is used for various sections of the bed, allowing users to assemble different configurations using identical connection methods, thereby reducing operational complexity despite the modular design
Solution Approach 2:
Multiple functional features are integrated into single components where possible. For example, support structures combine both structural and adjustment functions, and coupling mechanisms incorporate both connection and alignment features in one integrated system, reducing the overall number of separate parts

AI summary
A modular adjustable bed includes a bed frame unit, front and rear sliding frames disposed to be slidable on the bed frame unit, a head support frame pivotally mounted on the front sliding frame, a pair of prop links coupling the head support frame to a front frame of the bad frame unit, and a leg support frame pivotally mounted on the rear sliding frame. When the head support frame is driven to be displaced to a head elevated position from a head normal position, the front sliding frame is displaced to a front position from a rear position. The leg support frame can be driven to move from a leg normal position to a leg elevated position.
