Bedding foundation having multiple lift actuators for massage effect
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional adjustable bed bases are heavy, expensive, and difficult to transport due to their motorized components, while stationary foundations lack the massage and lumbar support features of adjustable bases.
Innovation Solution
A bedding foundation with a rectangular frame and platform that incorporates multiple lift actuators to raise and lower lift plates in a predetermined pattern, providing massage and lumbar support without the need for extensive motorization, thus combining the benefits of both types of foundations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If adjustable bed bases use motorized components to provide massage and lumbar support, then massage and lumbar support features are improved, but weight and ease of transport deteriorate
Solution Approach 1:
The patent extracts the essential massage function from complex motorized systems by using simple lift actuators that raise and lower lift plates through openings in the platform. This removes unnecessary motorized components while retaining the core massage and lumbar support functionality, significantly reducing weight and improving ease of transport.
2Adaptability or versatility
If adjustable bed bases include motors and moving parts, then massage and lumbar support features are improved, but device complexity increases
Solution Approach 1:
The patent removes complex motorized components and moving parts from the system, retaining only the essential lift actuators and lift plates. This extraction simplifies the overall device structure while maintaining the ability to provide massage and lumbar support through controlled vertical movement of the lift plates.
Solution Approach 2:
The massage function is segmented into multiple independent lift actuators positioned at different locations on the platform. Each actuator can be controlled independently to provide localized massage and lumbar support, achieving complex functionality through simple, modular components rather than a single complex motorized system.
3Adaptability or versatility
If adjustable bed bases use extensive motorization, then massage and lumbar support features are improved, but cost increases
Solution Approach 1:
The patent replaces expensive motorized components with simpler, more cost-effective lift actuators and lift plates. These simpler components are easier to manufacture and assemble, significantly reducing production costs while maintaining the essential massage and lumbar support functionality.

AI summary
A bedding foundation has a linear actuator for moving a roller carriage forward and backwards. The roller carriage includes wheels which move along rails supported below a rigid platform having an opening extending through the platform. The roller carriage includes a lifter which raises and lowers a roller independently of the movement of the linear actuator. Regardless of the position of the linear actuator, the roller may be raised or lowered. The roller moves back and forth inside the opening extending through the rigid platform and imparts a massage movement to a mattress above the foundation.
