Legless Folding Adjustable Bed Platform for Platform Bed Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional adjustable bed designs with legs are incompatible with platform beds that have storage drawers, as the legs interfere with drawer operation and placement, limiting their use on flat surfaces without legs.
Innovation Solution
A legless, folding adjustable bed platform with two support frames pivotally connected and equipped with actuators that allow the articulating portions to fold and adjust without projecting below the frame, enabling placement on any flat surface, box spring, or bed frame, using sliding tracks and actuators within the same plane to lift the articulating frames.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional adjustable bed designs with legs are used, then the bed structure is stable and complete, but the legs interfere with platform bed storage drawers and prevent placement on flat surfaces without legs
Solution Approach 1:
The invention removes the legs from the adjustable bed platform, extracting the problematic element that interferes with storage drawers and platform bed compatibility. The bed platform is designed to rest directly on the support surface without legs, eliminating the interference issue while maintaining structural stability through the frame design itself.
Solution Approach 2:
The articulating portions of the frame are nested within the same plane as the fixed support structure, creating a compact configuration that eliminates the need for legs. The nested design allows the bed to fit within the footprint of platform beds with storage drawers without interfering with drawer operation.
2Ease of operation
If actuators are positioned below the frame for operation, then the articulating portions can be lifted effectively, but the actuators cannot be operated on flat surfaces without legs
Solution Approach 1:
The actuators are repositioned from a vertical arrangement below the frame to a horizontal arrangement within the plane of the support frame. This dimensional change allows the actuators to operate effectively while remaining within the frame's footprint, enabling compatibility with flat surfaces and platform beds without requiring legs for actuator placement.
3Device complexity
If the articulating portion rests on top of the fixed support structure, then the design is simple, but dimensional height issues prevent use on platform beds with storage drawers
Solution Approach 1:
The articulating portion is nested within the same plane as the fixed support structure rather than resting on top of it. This nested configuration reduces the overall dimensional height of the frame assembly, allowing it to fit within the limited space available on platform beds with storage drawers while maintaining structural simplicity.

AI summary
An adjustable power bed layer that has a bed frame that folds from a flattened state to a folded state and from a flattened state to an adjusted state. The bed frame has an inner and outer frame that nest with each other in the flattened state. Head side and foot side actuators drive sliding members back and forth along respective tracks to pivot respective articulating frames between the flattened and adjusted states. The articulating frames are part of one of the inner and outer frames and the tracks are connected to the other of the inner and outer frames. In the folded state, the bed frame is positioned to that one of head side and foot side actuators becomes accessible for maintenance and servicing from above depending upon which way the bed frame is folded about its folding pivot.
