Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bed frames are cumbersome to assemble, heavy, and require extensive storage space due to their length and weight, making them difficult to transport and assemble without tools.
Innovation Solution
A collapsible mattress support system with hinge plates and pivotally attached side bars that can be easily assembled and disassembled, allowing for compact packaging and lightweight transportation, featuring extendable cross bars to accommodate various mattress sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If conventional bed frames use single-piece side rails and fixed cross bar members, then structural stability is improved, but the length of packaging box increases and weight increases
Solution Approach 1:
The side rails are divided into multiple telescoping sections that can slide relative to each other. The first side rail includes a first section and a second section that telescope, allowing the side rail to be compact for shipping but extend to full length for use. This segmentation enables the packaging box length to be reduced while maintaining the ability to support full-size mattresses.
Solution Approach 2:
The bed frame transitions from a static, fixed-length structure to a dynamic, adjustable-length structure. The telescoping sections allow the side rails to change length between a compact configuration for shipping and a fully extended configuration for use, adapting to different shipping and usage requirements.
2Stability of the object's composition
If conventional bed frames use single-piece side rails, then structural stability is improved, but weight increases and ease of assembly worsens
Solution Approach 1:
Dividing the side rails into multiple telescoping sections reduces the weight of individual components that need to be handled during assembly. While the total weight of the frame remains similar, the segmented structure allows for easier manipulation and assembly without requiring multiple people or special tools.
3Ease of manufacture
If conventional bed frames use fixed-length cross bar members, then manufacturing simplicity is improved, but adaptability worsens
Solution Approach 1:
The cross bar members are made adjustable with telescoping sections that can be extended or retracted to accommodate different mattress widths. This dynamic adjustment capability allows a single bed frame design to support multiple mattress sizes from twin to California king, greatly improving versatility without significantly complicating manufacturing.
4Strength
If conventional bed frames use heavy steel construction, then strength is improved, but ease of operation worsens
Solution Approach 1:
The heavy steel frame is segmented into multiple lighter sections that can be easily assembled and disassembled. The telescoping design allows sections to be connected through simple sliding and locking mechanisms rather than requiring complex welding or bolting operations, making assembly easier while maintaining overall structural strength.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system allows for easy assembly, reduced shipping costs, and efficient storage and transportation of a sturdy mattress support that can accommodate different mattress sizes within a compact and lightweight packaging, facilitating solo handling by customers.
Implementation Method 1
Each of the four side bars has a common width. A first distance between the axes about which the first and second bars rotate equals a second distance between the axes about which the third and fourth bars rotate plus twice the common width of the bars.
Implementation Method 2
The mattress support includes hinge plates on opposite sides of a middle cross bar. The plates are coplanar. First and second side bars are pivotally attached to one hinge plate, and third and fourth side bars are pivotally attached to the other hinge plate.

AI summary
A collapsible mattress support for a box spring includes hinges on opposite sides of a middle cross bar. First and second side bars are pivotally attached to one hinge, and third and fourth side bars are pivotally attached to the other hinge. Each of the bars rotates about parallel axes that are orthogonal to the hinges. The four side bars each has a common width. A first distance between the axes about which the first and second bars rotate equals twice the common width of the bars plus a second distance between the axes about which the third and fourth bars rotate. In one embodiment, the cross bars are extendable. The components of the mattress support for Queen, California King and Eastern King sized mattresses fit in a packing box whose length is no greater than 45 inches and whose width and height are each no more than 7 inches.
