Motorized bed and bed frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motorized beds lack sufficient support for upper frames, leading to vibrations and unbalanced loads, which can cause damage and safety issues, and do not allow for individualized positioning preferences.
Innovation Solution
A motorized bed frame design featuring a lower frame with actuating and gearing units, including adjustable columns, gearing pieces, and fixation-gearing-linking pieces that allow independent movement and positioning of upper sub-frames, dispersing loads across components to reduce vibrations and enhance stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple portions of the upper frame are moved concurrently, then the bed can achieve complex positioning, but the device complexity and load on components increases
Solution Approach 1:
The upper frame is divided into multiple independent movable portions (head portion, foot portion, side portions) that can be positioned independently. Each portion has its own actuating unit and gearing mechanism, allowing complex positioning without requiring all portions to move simultaneously, thus reducing operational complexity while maintaining versatility.
Solution Approach 2:
The bed frame employs dynamic positioning where different portions of the upper frame can be moved independently to different positions. The actuating units and gearing pieces enable each section to achieve and hold various angles and positions, providing adaptability without requiring concurrent movement of all sections.
2Device complexity
If the upper frame is supported with minimal components, then the device complexity is reduced, but vibrations and stability increase
Solution Approach 1:
The actuating unit and gearing unit are integrated into a combined assembly that provides both support and positioning functions. The gearing pieces are mounted on the lower frame and directly engage with the upper frame portions, creating a unified support structure that reduces vibrations while maintaining relatively simple complexity.
Solution Approach 2:
The gearing pieces act as intermediary components between the lower frame and upper frame portions. These gearing mechanisms provide structural support and reduce vibrations by distributing loads through the gear teeth engagement, adding stability without requiring excessive support components.
3Device complexity
If load is concentrated on one or a few components, then the device complexity is reduced, but reliability and safety deteriorate
Solution Approach 1:
The load support function is segmented across multiple independent gearing units and actuating units distributed at different locations on the lower frame. Each unit supports a specific portion of the upper frame, distributing the overall load across multiple components rather than concentrating it on a single structure, thereby improving reliability while maintaining manageable complexity.
4Stability of the object's composition
If the upper frame is made rigid, then the stability is improved, but the ability to reposition and adapt to individual preferences is reduced
Solution Approach 1:
The upper frame is designed with dynamic characteristics, allowing different portions to be positioned at various angles and positions independently. The actuating units can move each section to desired positions and hold them there, providing both stability in the positioned state and flexibility for repositioning to meet individual preferences.

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 positioned to meet individual needs. In some cases, the motorized bed frame includes additional or optional components to help dispersing the load and stabilizing the bed frame during operation.
