Pull Up Push Down Bed Rail with Segmented Lock and Pressure Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bed rails that swing down require caregivers to manually manipulate the mechanism, which can be cumbersome and do not effectively separate the function of keeping the rail in an upright position from resisting outward pressure, such as from a child rolling against it.
Innovation Solution
A portable bed rail with a U-shaped support member that can be pulled up and pushed down, featuring elongate through openings in the bases and cross support members to maintain the rail's position and resist outward pressure, allowing for easy assembly and disassembly without compromising integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If swing down bed rails use a single lock mechanism for both opening/closing and resisting outward pressure, then the device complexity is reduced, but the reliability of resisting outward pressure deteriorates
Solution Approach 1:
The patent divides the original single lock mechanism into two separate functional components: a lock mechanism for opening and closing the bed rail, and a separate outward pressure resistant mechanism. This segmentation allows each component to be optimized for its specific function, improving overall reliability while maintaining manageable complexity.
Solution Approach 2:
The base structure serves multiple functions: it provides structural support, houses the lock mechanism, and incorporates the outward pressure resistant mechanism through its elongate opening design. This multi-functionality reduces the need for additional separate components, managing device complexity while ensuring reliable pressure resistance.
2Ease of manufacture
If swing down bed rails require manual manipulation of the mechanism, then the ease of operation deteriorates, but the manufacturing precision can be maintained
Solution Approach 1:
The bed rail is designed to be dynamically movable between raised and lowered positions through a simplified mechanism. The elongate opening allows the support member to move freely while maintaining structural integrity, making operation easier without compromising manufacturing precision.
Solution Approach 2:
The outward pressure resistant mechanism automatically engages and disengages based on the position of the support member, eliminating the need for manual manipulation of separate locking mechanisms for pressure resistance. The system self-adjusts to maintain reliability during operation.
3Ease of operation
If the bed rail is designed to be portable and easily assembled, then the device complexity is reduced, but the strength of the connection deteriorates
Solution Approach 1:
The bed rail is divided into separable components (base, support member, cross support members) that can be easily assembled and disassembled. The elongate opening design allows these segments to connect securely while maintaining the strength needed to resist outward pressure, achieving both portability and connection integrity.

AI summary
The present pull up push down bed rail includes first and second bases that engage a bed, upper and lower cross supports extending between the bases to be adjacent to a near side of the bed to close off any gap between the near side of the bed and the bed rail, and a U-shaped support member having end members that engage the bases. The bases include through openings for the end members that extend into and through the through openings such that the U-shaped support member is pushable down, after which the U-shaped support member is pullable up. Sheeting is engaged to the U-shaped support member.
