Adjustable Bed Frame Coupling for Tool-Free Secure Joining
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a secure and easily releasable method to couple two beds or bed frames together without requiring tools, as existing solutions either lack stability or are cumbersome, especially in applications like hotels where flexibility is necessary, and there is a lack of simple, market-available devices for combining single beds into a double bed.
Innovation Solution
A coupling device with a foot and stem that includes a support bracket with parallel wall elements, allowing frame sections to be securely connected without tools, featuring adjustable height through a threaded spindle and sleeve, and a protective rubber-like material for floor compatibility, enabling secure and tool-free connection of beds of varying heights and manufacturers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two beds are merely pushed into each other without any coupling device, then the arrangement is simple and requires no additional components, but the connection is insecure and users may fall between the beds
Solution Approach 1:
The coupling device is divided into distinct functional segments: a support bracket with wall elements for securing bed frames, a height adjustment mechanism with spindle and sleeve, and a foot with protective material. This segmentation allows each component to perform its specific function efficiently while keeping the overall device relatively simple.
Solution Approach 2:
The height adjustment mechanism employs a nested structure where the spindle is inserted into the sleeve, and the foot contains the height adjustment means. This nesting reduces the overall footprint and simplifies the device structure while maintaining the necessary functionality for secure and adjustable bed coupling.
2Reliability
If bolt connections are used to securely join bed frames, then a secure connection is achieved, but the process becomes cumbersome and requires tools for installation and detachment
Solution Approach 1:
The coupling device transitions from a static bolted connection to a dynamic, adjustable connection. The height adjustment mechanism allows the device to adapt to different bed heights, and the wall elements can be easily inserted into and removed from the bed frame spaces, enabling tool-free installation and detachment while maintaining security.
Solution Approach 2:
The support bracket with wall elements acts as an intermediary between the two bed frames, providing a secure connection without requiring direct bolting of the frames together. This intermediary device simplifies the connection process while ensuring stability.
3Reliability
If a U-formed bracket with bolts is used to connect bed frames, then a secure connection is achieved, but tools are necessary for mounting and the arrangement is proprietary to specific frame dimensions
Solution Approach 1:
The coupling device is designed with universal adaptability through its adjustable height mechanism and generic support bracket structure. The wall elements can accommodate bed frames of various dimensions, and the height adjustment allows the device to work with different bed types and manufacturers, eliminating proprietary limitations.
Solution Approach 2:
The height of the support bracket can be adjusted by rotating the spindle within the sleeve, changing the vertical parameter of the device. This parameter adjustment enables the coupling device to adapt to different bed frame heights and configurations, enhancing versatility while maintaining secure connection.
4Adaptability or versatility
If the coupling device height is fixed, then the structure is simpler, but the device cannot accommodate beds of different heights or manufacturers
Solution Approach 1:
The coupling device incorporates a dynamic height adjustment mechanism where the spindle can rotate within the sleeve to change the effective height. This dynamic adjustment capability allows the device to adapt to different bed heights while keeping the adjustment mechanism relatively simple and intuitive.
