Stable bedstead with detachable interior support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bedsteads are unstable and prone to shaking or vibrating due to their design, which includes rotatable bars that can cause instability during use.
Innovation Solution
A bedstead design featuring a frame with an interior support system that includes pivotally connected connecting bars and outer legs, where the connecting bars are restricted from rotating beyond an unfolded position by an upper segment, and outer legs are secured with fastening members to prevent collapse, enhancing stability and ease of assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If bars are made rotatable with respect to the central support to enable assembly and disassembly, then ease of operation is improved, but stability deteriorates causing shaking or vibration during use
Solution Approach 1:
The bedstead employs a dynamic design where bars are rotatable during assembly but become fixed during use. The connecting bars can rotate relative to the central support during assembly/disassembly operations, but when deployed, they are positioned and secured to prevent rotation, thus achieving both ease of operation and structural stability.
Solution Approach 2:
The bedstead is divided into separable components (central support, connecting bars, outer legs) that can be independently assembled and disassembled. Each bar is a separate element that can be attached to the central support through rotation, allowing easy assembly while maintaining stability when properly positioned and secured during use.
2Adaptability or versatility
If bars are made rotatable to allow folding and storage, then adaptability is improved, but reliability deteriorates due to potential instability
Solution Approach 1:
The design implements dynamic bars that transition between rotatable and fixed states. During folding and storage, bars rotate to compact positions, but during use, they are secured in stable configurations. This dynamic behavior enables both adaptability for storage and reliability during operation.
Solution Approach 2:
The bar connections are designed with preliminary positioning features that ensure proper alignment and stable positioning when bars are attached to the central support. This preliminary action during assembly ensures that once positioned, the bars maintain reliable and stable connections during use.

AI summary
A bedstead includes a frame, an interior support removably coupled with the frame, and outer legs supporting the frame when the bedstead is set up. The interior support includes an inner leg, first connectors disposed circumferentially around the inner leg and connecting bars. Each connecting bar has one end pivotally connected with the inner leg through a first connector, and the other end to be removably coupled with the frame. When in use, the first connector restricts the movement, in particular, the rotation of the connecting bar, and thus enhances the overall structural stability of the bedstead.
