Edge Attachment Structure for Modular Folding Mattress Support
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 widths and easy disassembly for compact storage, reducing weight and manufacturing costs while accommodating various mattress dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional thick cross-bars and vertical bars are used to provide bearing strength, then the bed frame achieves stable support, but the bed frame becomes heavy and bulky
Solution Approach 1:
The bed frame is divided into multiple standardized assemblies (head assembly, foot assembly, side assemblies) that can be manufactured separately and connected together. This segmentation allows each component to be optimized for strength-to-weight ratio, using thinner bars that are sufficient for their specific load requirements rather than requiring thick bars throughout the entire frame.
Solution Approach 2:
The patent employs composite construction by combining metal bars with fabric panels and connecting mechanisms. The metal bars provide structural strength while the fabric panels distribute loads, allowing the use of thinner, lighter metal components compared to solid metal construction while maintaining bearing strength.
2Ease of manufacture
If a single bed frame size is manufactured to fit multiple mattress dimensions, then manufacturing costs are reduced, but the bed frame cannot accommodate various mattress sizes properly
Solution Approach 1:
The bed frame is divided into standardized modular assemblies (head assembly, foot assembly, side assemblies) that can be manufactured in standard sizes and then configured in different combinations to accommodate various mattress dimensions. This allows a single manufacturing process to produce components that can be assembled into multiple bed sizes.
Solution Approach 2:
The standardized assemblies are designed to be universal components that can serve multiple functions and configurations. The same head assembly and side assemblies can be used across different bed size configurations, allowing the system to accommodate single, double, queen, and king mattress sizes using the same basic component set.
3Stability of the object's composition
If the bed frame is designed as a unitary structure, then structural stability is maintained, but transportation and installation become difficult
Solution Approach 1:
The bed frame is divided into multiple standardized assemblies that can be manufactured, packaged, and transported separately in compact sizes. These assemblies are designed to be easily handled and moved through standard doorways and hallways, then quickly assembled on-site to form the complete bed frame structure.
Solution Approach 2:
The standardized assemblies are pre-manufactured and pre-assembled to a degree before shipping, with connection points and mounting features already prepared. This preliminary preparation allows for rapid on-site assembly while maintaining structural stability, eliminating the need for complex field fabrication or heavy lifting equipment.

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.
