Magnetic Frame Connection for Tool-Free Bed Configuration Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beds, particularly double beds, face issues such as labor-intensive reupholstering due to damage or soiling, difficulty in converting between single and double configurations, and inefficient access to all sides during maintenance, along with potential shifting during use.
Innovation Solution
A bed design utilizing permanent magnets in identical positions on adjacent frames to create a detachable magnetic connection, allowing easy conversion between single and double configurations, and providing easy access to all sides without tools, with optional ferromagnetic plates and a non-ferromagnetic cover for aesthetic appeal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If single beds are firmly connected using screws to prevent shifting, then stability is improved, but conversion time and complexity increase significantly
Solution Approach 1:
The patent replaces the screw-based mechanical connection system with a magnetic field-based connection system. Permanent magnets embedded in the frame structures create magnetic attraction forces that hold the beds together without requiring tools or complex mechanical assemblies, enabling tool-free conversion while maintaining stability.
Solution Approach 2:
The patent changes the connection parameter from mechanical (screws requiring tool intervention) to magnetic (field-based attraction). This parameter change allows the connection strength to be sufficient for stability while enabling easy separation by overcoming the magnetic force, thus reducing conversion time and complexity.
2Stability of the object's composition
If beds are firmly connected to prevent shifting during sleep, then positional stability is improved, but ease of conversion between configurations deteriorates
Solution Approach 1:
The patent substitutes mechanical fastening systems with magnetic field interactions. The magnetic connection provides sufficient holding force to maintain positional stability during sleep, yet allows easy separation by applying minimal force to overcome the magnetic attraction, greatly improving ease of conversion.
Solution Approach 2:
The magnetic connection system provides dynamic adaptability - maintaining stable connection during normal use (sleeping) while allowing easy separation when needed (conversion). The magnetic force automatically adjusts to provide holding strength without requiring active maintenance or complex mechanisms.
3Ease of operation
If magnetic connections are used for tool-free assembly, then ease of operation is improved, but connection strength under mechanical stress may be insufficient
Solution Approach 1:
The patent merges multiple magnetic elements into a coordinated magnetic array within the frame structure. By combining several magnets working together, the system achieves sufficient total connection strength to resist mechanical stresses during sleep while maintaining tool-free operation for assembly and disassembly.
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
Enables secure, tool-free conversion between single and double bed configurations and easy access to all sides for maintenance, maintaining a stable position under mechanical stress while ensuring an aesthetically pleasing appearance.
Implementation Method 1
The positional relationship of the adjacent or adjoining beds is held in a detachable manner by a magnetic arrangement. In this regard, there are several permanent magnets located in the area of the frame or in the area of a bed box.

AI summary
The invention relates to a bed, in particular a bed, with sleeping or resting areas that can be arranged side by side, each having a frame and comprising upholstery and/or a mattress, wherein a multiple, in particular a double, bed can be formed by arranging them side by side. According to the invention, it is essential to be able to arrange essentially classic upholstered beds, box spring beds, or other loose bed bases side by side in such a way that the desired close proximity is maintained even under corresponding mechanical stress, but without the use of tools or complex mechanical handling, it is possible to convert the double bed back into two single beds or to create very easy access to all sides of such a double bed by being able to separate the respective frames without effort.
