Furniture objects including a convertible desk bed
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Furniture that combines a desk and a bed often occupies too much space, especially when additional working surfaces are required, and existing solutions like futon beds may still be unstable and inconvenient during transitions.
Innovation Solution
A convertible furniture apparatus with a frame and a pivot-based assembly that transitions between a desk and a bed position, using a binding assembly and gliding device to maintain stability and levelness, and a mechanical assembly with a gas lift for counterbalance, allowing seamless conversion without complex mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a convertible furniture apparatus combines a desk and bed in one structure, then space efficiency is improved, but the device becomes inherently unstable during transitions between positions
Solution Approach 1:
The patent implements a dynamic conversion mechanism where the bed assembly can pivot between a stored position (parallel to desktop) and a deployed position (perpendicular to desktop) through pivot points at the corners of the frame. This dynamic capability allows the furniture to adapt its configuration while maintaining stability through controlled mechanical movement rather than fixed rigid structures.
Solution Approach 2:
The patent employs a gas lift mechanism that provides counterbalancing force to offset the weight of the bed assembly during conversion and positioning. The gas lift is configured to transmit force to the bed assembly, making it easier to move and hold the assembly in the desired position without requiring excessive manual effort, thereby maintaining stability during transitions.
2Ease of operation
If a convertible furniture apparatus uses a pivot-based conversion mechanism, then ease of operation is improved, but the desktop may become unlevel during transitions
Solution Approach 1:
The patent employs a parallelogram linkage mechanism formed by connecting legs and side rails that maintains the desktop's level orientation during the conversion process. As the bed assembly pivots, the parallelogram geometry ensures that the desktop remains parallel to its original position, preventing it from becoming unlevel while allowing smooth operational conversion.
3Reliability
If a convertible furniture apparatus includes additional structural elements for stability, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent designs the frame and convertible assembly to serve multiple functions: the frame provides structural support, the pivot points enable conversion movement, the gas lift assists with positioning, and the parallelogram linkage maintains levelness. This multi-functionality reduces the need for additional specialized structural elements, maintaining reliability while controlling complexity.

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 stable and convenient conversion between desk and bed positions, maintaining a level desktop and reducing instability, while optimizing space usage without additional structural elements, thus enhancing user convenience and functionality.
Implementation Method 1
a gas lift configured to transmit a force to the hook arm to counterbalance a weight of the convertible assembly
Implementation Method 2
a convertible assembly connected to the frame via at least a pair of pivot points each connected to respective side panels of the frame, the convertible assembly configured to transition between a first position and a second position by pivoting about the pivot points
