Foldable electric bed frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increased thickness of a folded bed board resulting from a higher angle of inclination of the push rod in electric beds leads to higher transportation costs, as existing designs require larger bed board thicknesses to maintain structural integrity.
Innovation Solution
A foldable electric bed frame with a push rod that features a height adjusting piece and a height locking piece, allowing the distance from the height adjusting piece to the second board to be adjustable, reducing the thickness of the folded bed frame while maintaining a good force-bearing condition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the angle of inclination of the push rod is increased to reduce the required push force, then the force-bearing condition is improved, but the thickness of the bed board must be increased, leading to higher transportation costs
Solution Approach 1:
The patent applies the dynamics principle by making the push rod's mounting position adjustable rather than fixed. The connection device includes a connection seat that can be positioned at different locations on the bed board, allowing the push rod's angle of inclination to be optimized for force-bearing while maintaining a thin bed board profile. This dynamic adjustability resolves the contradiction between needing a larger inclination angle for strength and keeping the bed board thin for transportation.
2Strength
If the thickness of the bed board is increased to accommodate a larger push rod inclination angle, then the structural integrity is improved, but the transportation volume efficiency deteriorates
Solution Approach 1:
The patent segments the connection function between the bed board and push rod by introducing a separate connection seat. This connection seat can be positioned at different locations on the bed board surface without increasing the bed board's overall thickness. The segmentation allows the push rod to be mounted at the optimal angle for structural integrity while keeping the bed board profile thin for efficient transportation.
3Device complexity
If the mounting positions of the push rod are fixed to simplify the structure, then the device complexity is reduced, but the adaptability to different force requirements deteriorates
Solution Approach 1:
The connection seat serves multiple functions: it provides a mounting point for the push rod, allows adjustment of the push rod's angle of inclination, and can be positioned at different locations on the bed board. This multi-functional design maintains relative structural simplicity while providing the adaptability needed to optimize force-bearing conditions for different bed configurations and load requirements.

AI summary
The present invention relates to the field of electric bed technologies, which provided a foldable electric bed frame comprising a bottom frame and a push rod; a first board and a second board hinged to each other are disposed on the top of the bottom frame, one end of the push rod is rotatably connected to a side edge of the second board through a connection device which comprises a height adjusting piece and a height locking piece; a distance from the height adjusting piece to the second board in a working state is larger than a distance from the height adjusting piece to the second board in a folded state, and the height locking piece locks a position of the height adjusting piece in the working state. The present invention has solved the problem of an increased thickness of a folded bed board resulting from increase of an angle of inclination of a push rod in the prior art, which is time and labor saving and more flexible and convenient to use.
