Folding Mattress Support Frame for Lighter Adjustable Bed Bases
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional folding bed frames are heavy, awkward, and not adaptable to different mattress sizes, leading to increased manufacturing costs and difficulties in transportation and installation.
Innovation Solution
A folding bed frame with standardized right and left bed frame assemblies connected by central connecting bars, allowing for adjustable mattress support and easy disassembly for transportation, featuring leg brackets that pivot and edge attachments for securing a bed skirt and headboard.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If conventional unitary bed frame design is used, then structural stability is achieved, but weight and bulk increase making it awkward to transport
Solution Approach 1:
The bed frame is divided into two separate standardized frame assemblies (left and right) that can be manufactured independently and transported separately. Each assembly is less than half the width of a conventional bed frame, making them easier to handle and transport while maintaining structural integrity when assembled together with central connecting bars.
2Strength
If conventional unitary bed frame design is used, then bearing strength is provided, but manufacturing cost increases due to inability to standardize
Solution Approach 1:
The frame is segmented into standardized left and right assemblies that can be mass-produced using the same manufacturing processes and materials. This standardization reduces tooling costs, simplifies production planning, and allows for economies of scale while maintaining the bearing strength required to support mattresses of various sizes through proper structural design of each module.
Solution Approach 2:
The standardized frame assemblies are designed to be universal components that can accommodate multiple mattress dimensions (single, double, queen, king, California king) by adjusting the number and configuration of central connecting bars. This multi-functionality eliminates the need to manufacture different frame sizes for different mattress types, significantly reducing manufacturing costs.
3Reliability
If conventional bed frame design is used, then support for mattress is provided, but adaptability to different mattress sizes is lost
Solution Approach 1:
The frame system incorporates adjustable central connecting bars that can be configured in different numbers and positions to dynamically adapt to various mattress widths. This allows the same standardized frame assemblies to reliably support different mattress sizes (from single to California king) by simply adjusting the connecting configuration rather than requiring different frame designs.
4Strength
If thick cross-bars are used, then bearing strength is increased, but device complexity and bulk increase
Solution Approach 1:
Instead of using thick cross-bars in a conventional welded design, the frame uses thinner vertical bars spaced at small intervals within each standardized assembly, connected by fewer, simpler horizontal members. The bearing strength is distributed across multiple smaller elements rather than concentrated in few thick members, reducing overall material usage and structural complexity while maintaining support capability.

AI summary
A folding mattress support system replaces both a conventional box spring and the bed frame with rails. The mattress support system is lighter, quieter and easier to transport, and also provides more storage space beneath the mattress. The mattress support system includes bed frame assemblies, central connecting bars, edge attachments and a bed skirt. Leg brackets fold out from the bed frame assemblies, which themselves unfold in the middle. Central connecting bars connect inner side edges of the bed frame assemblies. Plastic edge attachments are attached at outer corners of the bed frame assemblies and hold a bed skirt taught around the frame assemblies when the frame assemblies are standing on the extended leg brackets. A mattress is then placed on top of the assembled mattress support system. Optionally, metal edge attachments at the head corners of the mattress support system both hold the bed skirt and support a headboard.
