Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motorized beds face issues such as limited adjustability to meet individual preferences and instability due to dislocation or deformation of gearing units, leading to vibrations and unbalanced loads.
Innovation Solution
A motorized bed frame design featuring a lower frame with a supporting structure, actuating units, gearing units, and linking pieces that allow independent movement of upper sub-frames, along with a spacer to stabilize the gearing unit, dispersing loads and reducing vibrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If gearing units are used to move the upper frames, then the bed can be motorized and convenient to use, but the gearing units are likely to dislocate or deform due to loads, causing vibration and instability
Solution Approach 1:
The patent introduces linking pieces as intermediary components between the gearing units and the bed frame. These linking pieces act as mediators that connect the gearing mechanism to the structural frame, allowing the gearing units to function while distributing loads through the linking pieces to reduce direct stress on the gearing components, thereby preventing dislocation and deformation.
Solution Approach 2:
The bed frame is divided into separate modular components including the lower frame, upper frame, and linking pieces. This segmentation allows the gearing units to be isolated from direct structural loads by being connected through the linking pieces, enabling the motorized function while improving reliability by preventing load-induced deformation of the gearing mechanism.
2Ease of operation
If gearing units are used to move the upper frames, then motorized functionality is achieved, but unbalanced loads can damage components and make the bed unsafe
Solution Approach 1:
The linking pieces serve as intermediary elements that distribute unbalanced loads from the gearing units across multiple connection points to the lower frame. This mediation prevents concentrated forces from damaging individual components, thereby improving component durability while maintaining motorized operation capability.
Solution Approach 2:
The patent employs the lower frame and linking pieces as a counterbalancing structure that opposes and distributes the unbalanced loads generated by the gearing units during operation. This counterweight effect prevents excessive forces from damaging the gearing components and ensures safe operation.
3Device complexity
If only a portion of the upper frame is moved, then the structure is simpler, but it cannot meet individual preferences for customization
Solution Approach 1:
The upper frame is segmented into multiple independently movable portions that can be adjusted separately. This segmentation maintains relative structural simplicity while enabling customization, as each segment can be positioned independently to meet individual preferences without requiring complex integrated mechanisms.
Solution Approach 2:
The patent implements dynamic adjustability where different portions of the upper frame can be moved to different positions independently. This dynamic capability allows the bed to adapt to individual preferences while maintaining a relatively simple structural design through the use of modular, independently controllable segments.

AI summary
Disclosed are motorized beds and bed frames. A motorized bed frame includes a lower frame and an upper frame disposed above the lower frame. At one or each of first and second sides of the motorized bed frame, the motorized bed frame also includes an actuating unit and a gearing unit to move and position an upper sub-frame of the upper frame with respective to the lower frame. The upper sub-frames at the first and sides can be independently posited to meet individual needs. In some cases, the motorized bed frame includes additional or optional components to assist the gearing unit to reduce vibration and prolong the lifetime of the bed frame.
