Reinforced bed frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pole frame beds suffer from structural instability due to the lack of connection between adjacent bed poles, leading to subsidence under larger forces, as each bed pole relies solely on cross poles for support.
Innovation Solution
A reinforced bed frame design featuring connecting members with C-shaped movable and fixing buckles, along with a fastener structure, that securely fasten adjacent bed poles together, enhancing stability and load capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If bed poles are only connected to cross poles without inter-pole connections, then the structure is simple and easy to manufacture, but the bed frame becomes unstable and prone to subsidence under load
Solution Approach 1:
The connecting member is divided into multiple C-shaped fixing buckles (at least two) that can independently engage with adjacent bed poles. This segmentation allows each buckle to provide localized reinforcement at critical points along the bed pole, enhancing overall stability while maintaining manufacturing simplicity through modular components.
Solution Approach 2:
The C-shaped movable buckle is disposed inside the C-shaped fixing buckle, creating a nested configuration where the movable buckle can slide within the fixing buckle's C-shape. This nesting allows the movable buckle to provide additional reinforcement while being contained within the existing fixing buckle structure, adding stability without proportionally increasing complexity.
2Strength
If multiple C-shaped fixing buckles are used to connect adjacent bed poles, then the loading capacity is improved, but the assembly process becomes more complex
Solution Approach 1:
The C-shaped movable buckle is designed to be movable within the C-shaped fixing buckle, allowing it to slide into position during assembly and then lock into place. This dynamic feature enables workers to easily assemble the connection by simply inserting the movable buckle, which then provides additional strength through its engagement with the bed pole, without requiring complex alignment or fastening procedures.
Solution Approach 2:
The fastener structure automatically locks the C-shaped movable buckle to the C-shaped fixing buckle through their complementary geometries. The movable buckle's C-shape engages with the fixing buckle's C-shape in a self-locking manner, eliminating the need for additional fasteners or complex assembly steps. This self-service mechanism maintains ease of manufacture while providing the strength enhancement of multiple buckles.
3Reliability
If C-shaped movable and fixing buckles with fastener structures are used to surround bed poles, then structural integrity is enhanced, but the device complexity increases
Solution Approach 1:
The C-shaped movable buckle and C-shaped fixing buckle are combined into a single integrated connecting member that includes both elements. This merging reduces the number of separate components that need to be manufactured and assembled, thereby reducing overall device complexity while maintaining the structural integrity benefits of having both movable and fixing buckles with fastener structures.
Solution Approach 2:
The C-shaped fixing buckle serves multiple functions: it provides the primary connection structure, contains the movable buckle, and participates in the fastening mechanism through its engagement with the movable buckle. This multi-functionality reduces the need for separate components, simplifying the overall device while enhancing structural integrity through the combined actions of both buckle types.

AI summary
The present disclosure discloses a reinforced bed frame comprising a plurality of bed poles (10) spaced in parallel at intervals and at least one connecting member (30). Two ends of each of the plurality of bed poles (10) are respectively connected to two cross poles (20). Each of the at least one connecting member (30) comprises a body (32) and at least two C-shaped fixing buckles (34) connected to the body (32). Two C-shaped fixing buckles (34) are respectively locked to two adjacent bed poles (10). Each of one or more C-shaped movable buckle (36) is configured to cover an opening of a corresponding one of the at least two C-shaped fixing buckles (34) and cooperates with the corresponding one of the at least two C-shaped fixing buckles (34) to surround a corresponding one of the plurality of bed poles (10). Each of the at least two C-shaped fixing buckles (34) corresponds to a corresponding one of the one or more C-shaped movable buckle (36), and each of one or more fastener structure is configured to be movably locked together between the corresponding one of the at least two C-shaped fixing buckles (34) and the corresponding one of the one or more C-shaped movable buckle (36). One or more C-shaped fixing buckles (34) of each of the at least one connecting member (30) can respectively fasten the two adjacent bed poles (10), the one or more C-shaped movable buckler (36) encloses one or more opening of the one or more C-shaped fixing buckles (34) to be coupled to define one or more round hole, thereby holding one or more of the plurality of bed poles (10). Therefore, a loading capacity of the bed frame is greatly improved, and the bed frame is stabilized.
