Split End Piece Bed Frame for Barrier-Free Side Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beds lack improved access to the receiving space when side rails are in the non-use position, particularly for individuals using the bed in the sick or nursing context, where unhindered access from all sides is necessary for care and hygiene.
Innovation Solution
The bed design features a split end piece with a lower and upper section, allowing the upper section to be removed, enabling barrier-free access when side rails and end pieces are in the non-use position, with guide grooves for side rail movement and connecting bolts for secure assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the side rails are moved to the non-use position to improve access, then accessibility is improved, but the protective function is lost
Solution Approach 1:
The side rail is divided into multiple sections (first side rail section and second side rail section) that can be independently positioned. This allows the side rail to provide protection when needed while enabling access by moving only specific sections to non-use positions without compromising the entire side rail structure.
2Ease of operation
If the end piece is made removable to improve access from all sides, then accessibility is improved, but the structural integrity is reduced
Solution Approach 1:
The end piece is segmented into a first end piece section and a second end piece section that can be detachably connected. This allows complete removal of the end piece for full accessibility when needed, while maintaining structural integrity through secure connection during normal use.
Solution Approach 2:
The end piece transition from fixed to removable state allows dynamic adaptation between protection and accessibility modes, enabling full removal for comprehensive access while maintaining structural integrity during normal operation.
3Ease of operation
If the side rails and end pieces are made fully removable to improve access, then accessibility is improved, but the device complexity increases
Solution Approach 1:
The side rail and end piece are divided into sections with standardized connection interfaces. This segmentation enables modular assembly and disassembly, reducing complexity compared to complete redesign while still achieving full accessibility when needed.

AI summary
Bed, in particular a hospital and/or care bed, with a bed frame (2) which serves to accommodate a lying surface element (3), in particular a slatted frame, an end piece (4, 5) arranged on the end of the bed frame (2) and a side rail (6 , 9) which has two height-adjustable longitudinal bars (7, 8; 10, 11), which are each held at one end so that they can be moved vertically by means of a guide (14) provided by the end piece (4, 5), the end piece (4, 5) being designed in two parts and has a lower end piece section (15) in the height direction (13) of the bed (1) and an upper end piece section (16) in the height direction (13) of the bed (1), the upper end piece section (16) being detachably attached to the lower end piece section ( 15) is arranged.
