Extensible Convertible Bed Frame for Desk and Couch Comfort
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current convertible furniture pieces that combine bed and desk functions are uncomfortable due to high bed frames when in bed configuration, cannot accommodate a third couch function, and have narrow bed frames to accommodate the desk portion.
Innovation Solution
A foldable mattress topper serving as a traditional mattress topper, couch backrest cushion, and second mattress, combined with an extensible bed frame pivotally attached to an external frame, allowing the bed frame to rotate and the desktop to be raised or lowered while maintaining a horizontal orientation, enabling conversion between bed, desk, and couch configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the bed frame height is increased to accommodate computer monitors and speakers on the desk, then the desk functionality is improved, but the bed comfort and practicality deteriorate
Solution Approach 1:
The bed frame is made dynamically adjustable through a telescopic mechanism that allows the frame length to be extended or retracted. This enables the bed frame height to be optimized for comfort while the desk surface maintains adequate clearance for equipment, resolving the contradiction between bed comfort and desk functionality.
Solution Approach 2:
The bed frame is divided into separable sections that can be independently adjusted. The telescopic sections allow the frame to be extended when needed for desk clearance or retracted to optimize bed comfort, enabling independent optimization of both functions.
2Adaptability or versatility
If the bed frame width is reduced to accommodate the desk portion stored beneath, then space efficiency is improved, but the bed comfort and sleeping area deteriorate
Solution Approach 1:
The bed frame incorporates telescopic sections that allow the width to be dynamically adjusted. When the desk needs to be stored beneath, the frame retracts to provide clearance. When sleeping comfort is prioritized, the frame extends to provide adequate width, resolving the contradiction between space efficiency and bed comfort.
3Adaptability or versatility
If the bed frame is made narrow to accommodate the desk portion, then the furniture can be converted to couch configuration, but the bed functionality deteriorates
Solution Approach 1:
The telescopic bed frame allows dynamic adjustment between narrow and wide configurations. When couch conversion is needed, the frame retracts to a narrow profile. When bed functionality is prioritized, the frame extends to provide adequate width, enabling both functions to be optimized at different times.
4Adaptability or versatility
If the bed frame has considerable height for desk accommodation, then the desk can function properly, but the overall furniture profile becomes awkward and impractical
Solution Approach 1:
The telescopic mechanism allows the bed frame height to be dynamically adjusted. The frame can be extended to provide adequate clearance for desk equipment or retracted to create a lower, more practical profile, resolving the contradiction between desk functionality and overall furniture aesthetics.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a comfortable and space-efficient furniture piece that can function as a bed, desk, and couch, with a foldable mattress topper and extensible bed frame allowing for a comfortable couch configuration and maintaining the desktop's horizontal orientation during transitions, addressing the limitations of existing convertible furniture.
Implementation Method 1
A bed frame in pivotally attached to a larger, external frame that houses the entire convertible furniture piece. A desktop is also pivotally attached to the underside of the bed frame such that when the bed frame rotates upward, the bed frame pulls the desktop up to an elevated position.
Data Source
AI summary
A convertible furniture piece is disclosed, having a bed configuration, desk configuration, and couch configuration. The furniture includes an outer frame that houses a bed frame and desk, along with the mechanism for raising and lowering the bed frame and desk. The outer frame, bed frame, and desk are interconnected such that the bed frame and desk transition together between a bed configuration, where the desk sits directly below the bed frame, and desk configuration, where the bed frame is stored vertically, while keeping the desk level with the floor. The furniture may be converted to a couch by repositioning a foldable mattress topper as a backrest against the outer frame while the bed frame is horizontal. The furniture may further comprise a bed frame extension, allowing the foldable mattress topper to be repositioned as a second mattress alongside a first mattress.
