Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bunk bed guard rails are bulky, making them inconvenient for transportation, especially by sea, as they occupy large volumes and reduce loading capacity per container.
Innovation Solution
A bunk bed guard rail design featuring a rotating mechanism with a first rail frame and a second rail frame connected by hinges, a rotating shaft and sleeve tube, or a reinforcing mechanism with a tenon and insertion groove, allowing the rail frames to be locked and detached for packaging and transportation, increasing loading efficiency and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the guard rail is made as a complete large-volume component, then the safety performance is improved, but the transportation efficiency and container loading quantity deteriorate
Solution Approach 1:
The guard rail is divided into multiple detachable rail frames (first rail frame, second rail frame, third rail frame) that can be separated for transportation and assembled into a complete guard rail for use. This segmentation reduces the volume occupied during transportation while maintaining the complete protective function when assembled, thereby increasing container loading quantity without compromising safety performance.
2Volume of moving object
If the guard rail is made foldable, then the volume is reduced for storage and transportation, but the installation difficulty increases
Solution Approach 1:
Instead of making the guard rail foldable, the patent segments it into detachable rail frame components connected by rotating mechanisms. Each rail frame remains structurally simple and rigid, while the rotating connection mechanisms enable easy assembly and disassembly without requiring complex folding structures, thus reducing volume for transportation without significantly increasing installation difficulty.
Solution Approach 2:
The guard rail incorporates rotating mechanisms that allow the rail frames to rotate relative to each other, enabling dynamic assembly and disassembly. This dynamic connection system provides ease of installation and storage while maintaining the structural integrity and simplicity of individual rail frame components.
3Productivity
If the rotating mechanism and lock mechanism are added to enable detachment, then the transportation efficiency is improved, but the device complexity increases
Solution Approach 1:
The guard rail is segmented into modular rail frames with standardized rotating and locking mechanisms. This modularity allows the complex functions of detachment and reassembly to be distributed across simple, repeatable components rather than requiring a single complex mechanism, thereby improving transportation efficiency while managing device complexity through standardization.
Solution Approach 2:
The rotating mechanism provides dynamic connection between rail frames, enabling easy assembly and disassembly for efficient transportation. The lock mechanism ensures static stability when assembled. This combination of dynamic and static features achieves transportation efficiency without excessive complexity, as each mechanism performs a single, well-defined function.

AI summary
A bunk bed equipped with a guard rail, has a bed board frame, two side bed frames respectively disposed at the front and rear sides of the bed board frame to support the bed board frame and a guard rail disposed at the side of the bed board frame. The guard rail includes a first rail frame, a second rail frame and a rotating mechanism. The rotating mechanism connects the first rail frame and the second rail frame, such that the two rail frames rotate relatively in the horizontal direction or the longitudinal direction. The first rail frame is locked to the second rail frame by a lock mechanism to form a guard rail entirety. The rotating mechanism moveably connects the first rail frame and the second rail frame, the first rail frame and the second rail frame are locked by a lock mechanism to form a detachable guard rail.
