Foldable Bedstead Structure with Hinged Units for Space Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional beds occupy significant space and cannot be efficiently utilized in multi-functional living spaces due to their fixed horizontal arrangement, limiting space utilization in homes with limited bedrooms.
Innovation Solution
A folding bed structure featuring bedstead units hinged by a fixing rod with a motor, allowing the bed to be folded and adjusted for space efficiency, incorporating a support frame, bed board, and latticed support columns for seamless connection and easy assembly/disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If traditional beds are arranged horizontally on the ground, then the bed structure is simple and stable, but the bedroom space is largely occupied and cannot be fully utilized during the day
Solution Approach 1:
The bed structure is transformed from a static horizontal arrangement to a dynamic foldable structure. The bedstead units are hinged together and can be folded by a motor, allowing the bed to change its spatial configuration between horizontal (for sleeping) and vertical/folded (for space-saving) states, thus resolving the contradiction between structural stability and space occupation.
Solution Approach 2:
The bedstead units are designed to nest within each other when folded. The first bedstead unit and second bedstead unit can be folded together in a nested configuration, minimizing the space occupied by the bed during the day while maintaining structural integrity through the hinged connections and fixing rods.
2Area of stationary object
If the bedstead units are hinged to form a foldable structure, then space utilization is improved, but the structure complexity increases
Solution Approach 1:
The bedstead is divided into multiple independent bedstead units (first bedstead unit, second bedstead unit) that can be hinged together. Each unit can be independently folded and positioned, allowing the overall structure to achieve space-saving configuration through modular segmentation rather than a single complex moving mechanism.
Solution Approach 2:
Fixing rods are introduced as intermediary components to connect and secure the bedstead units during folding. The fixing rods act as mediators that enable the hinged connection between units while providing a simple mechanical solution for locking and securing the folded position, reducing the need for complex locking mechanisms.
3Ease of manufacture
If the bed board is integrated with outer frames and support bars, then assembly process is simplified, but the weight of the bed board increases
Solution Approach 1:
The bed board is merged with the outer frames and support bars into an integrated assembly. This combining of components simplifies the assembly process by reducing the number of separate parts that need to be assembled and ensures proper alignment and structural integrity, while the integration allows for optimized material distribution that balances strength requirements with weight considerations.

AI summary
A bed structure includes a bedstead formed by bedstead units. The bedstead units are symmetrically arranged with respect to the central axis of the bedstead. The bedstead unit includes a first bedstead unit and a second bedstead unit. The first bedstead unit is hinged to the second bedstead unit. A motor is provided between the first bedstead unit and the second bedstead unit. The bedstead units at both sides of the central axis of the bedstead are hinged by a fixing rod. Each of two ends of the fixing rod is provided with a clamping member. The bedstead unit is provided with a matching member connected to the clamping member. The clamping member and the matching member are hinged by a fastener. In this arrangement, the electric bed can be folded.
