Folding Bedstead with Hub-Based Segmentation for Easy Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bedsteads are difficult to assemble and disassemble, and their bulky dimensions make them heavy and cumbersome to move when folded, limiting user convenience and storage flexibility.
Innovation Solution
A bedstead design featuring a frame with pivotally connected lateral and longitudinal bars, a hub with notches for connecting bars, and removable supporting bars and legs, allowing for easy assembly and disassembly by facilitating folding into a compact configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the bedstead is folded into a compact configuration, then the volume is reduced, but the bedstead becomes heavy and difficult to move
Solution Approach 1:
The bedstead is divided into multiple independent segments including lateral bars, longitudinal bars, connecting bars, and a hub structure. These segments can be easily separated and reconnected through pivotal connections, allowing the bedstead to be disassembled into manageable components for effortless moving and storage, resolving the contradiction between compact volume and ease of operation.
2Ease of operation
If the bedstead is designed for easy assembly and disassembly, then the ease of operation is improved, but the structural complexity increases
Solution Approach 1:
A hub structure with multiple notches serves as an intermediary component that simplifies the connection between lateral bars, longitudinal bars, and connecting bars. This hub acts as a central organizing element that reduces the overall structural complexity while enabling easy assembly and disassembly operations through a standardized connection interface.
3Adaptability or versatility
If the bedstead uses pivotal connections for folding, then the adaptability is improved, but the manufacturing complexity increases
Solution Approach 1:
The pivotal connection mechanisms are merged into integrated joint structures where the connecting bars incorporate built-in pivot points and notches. This consolidation of multiple pivotal connections into unified joint elements reduces manufacturing complexity while maintaining the full folding capability and adaptability of the bedstead design.

AI summary
A bedstead includes a frame with first and second lateral bars and first and second longitudinal bars connected to each other at their adjacent ends. The bedstead also includes an interior support disposed in the interior defined by the frame when the bedstead is in the unfolded state. The interior support includes a hub with a plurality of notches, and a plurality of connecting bars each having a first end portion pivotally connected with a notch of the hub and a second end portion removably connected with the frame.
