Bed Frame with Recessed Plank Support to Prevent Mattress Sliding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bed frames fail to prevent mattresses from sliding due to the bed plank being flush with the side boards, which allows for lateral movement.
Innovation Solution
A bed frame design featuring U-shaped connecting members at the bottom of side boards, support members with short struts and positioning pieces, and a support spine that creates a gap between the bed plank and side boards, forming stop sides to restrain the mattress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the bed plank is made flush with the tops of the side boards, then the bed frame structure is simple, but the mattress slides left and right when in use
Solution Approach 1:
The patent introduces a vertical dimension by lowering the bed plank support frame below the top level of the side boards. This creates a vertical gap that translates into horizontal stopping surfaces, converting a two-dimensional flush arrangement into a three-dimensional structure with anti-sliding functionality.
Solution Approach 2:
The bed plank support frame is pre-positioned at a lower level to create stop sides that proactively prevent mattress sliding before it occurs. The stop sides form a preliminary barrier that restrains the mattress in the vertical direction, preventing lateral movement.
2Reliability
If the bed plank support frame is lowered to prevent mattress sliding, then mattress stability improves, but the device complexity increases
Solution Approach 1:
The bed plank support frame is divided into multiple support members that are independently connected to the side boards via U-shaped connecting members. This segmentation allows each component to be simple in structure while the assembled system achieves the complex function of preventing mattress sliding through the lowered configuration.
3Ease of manufacture
If the bed plank is flush with the side boards, then the bed frame is easy to manufacture, but it does not provide safety against falls
Solution Approach 1:
By lowering the bed plank support frame vertically, the patent creates stop sides that form a protective barrier. This vertical positioning change introduces a safety function that prevents falls, transforming the bed frame from a simple support structure to a protective enclosure.
Solution Approach 2:
The lowered bed plank support frame creates stop sides that proactively prevent falls before they can occur. The stop sides form a preliminary protective barrier that restrains the mattress and prevents it from sliding off the bed frame.

AI summary
A bed frame includes a frame, bed legs, and a bed plank support frame. The frame includes two side boards, a head board, and a tail board. Respective bottoms of opposing sides of the two side boards are provided with a plurality of U-shaped connecting members, respectively. The bed plank support frame includes a plurality of support members. Two ends of each support member are connected to U-shaped connecting grooves of the corresponding U-shaped connecting members of the two side boards, respectively. The bed plank support frame is sunk when in use. After a bed plank is placed, there is a certain distance between the bed plank and the top of the frame, so that the frame can form four stop sides. After a mattress is placed on the bed frame, the mattress is restrained in the frame, not sliding.
