Adjustable bed with tilting mechanisms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional adjustable beds have limited adjustability, which restricts users from achieving maximum comfort by not allowing sufficient customization of body positions.
Innovation Solution
An adjustable bed system with a bed frame, back lifting assembly, foot lifting assembly, and tilting mechanism, featuring motor-driven actuators and platforms that can be adjusted to various positions, including horizontal and sloping configurations, to accommodate user preferences for comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional adjustable beds are used, then basic position adjustment is provided, but adjustability is very limited
Solution Approach 1:
The bed system is divided into multiple independent adjustable segments: head platform, back platform, waist platform, seat platform, thigh platform, and foot platform. Each platform can be adjusted independently through its own actuator mechanism, allowing granular control over body positioning while maintaining overall system manageability through modular design
Solution Approach 2:
The bed system transitions from static to dynamic adjustability by incorporating multiple motorized actuators that enable real-time repositioning of different body zones. The swing arms and lifting mechanisms allow continuous movement between horizontal and elevated positions, providing dynamic adaptation to user comfort needs
2Adaptability or versatility
If multiple platforms and actuators are added for enhanced adjustability, then body position customization is improved, but device complexity increases
Solution Approach 1:
Multiple actuators are designed with identical structural configurations (motor member, outer tube, activation rod, mounting brackets), allowing standardized components to perform different functions at various body zones. This universal design reduces the variety of unique parts needed while achieving comprehensive body position customization
Solution Approach 2:
The actuator mechanisms are nested within the platform structures, with motor members housed in platforms and activation rods extending through mounting brackets. The swing arms are nested within the side rails, creating a compact hierarchical arrangement that minimizes spatial complexity while maintaining full adjustability functionality

AI summary
An adjustable bed includes a bed frame supporting a plurality of platforms having at least a head platform and a back platform, a back lifting assembly, a foot lifting assembly, a base frame pivotally and detachably connected to the bed frame, a bed frame tilting actuator pivotally connected to the bed frame and the base frame for operably adjusting the bed frame from the horizontal position to the sloping position relative to the base frame, or vice versa. The adjustable bed also includes a head platform tilting actuator pivotally connected to the head platform and the back platform for operably adjusting the head platform in a tilting position or a flat position relative to the back platform.
