Adjustable Bed Motor Pocket for Stronger, Quieter Vibration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adjustable beds often attenuate the vibratory massage action due to rigid mounting of massage motors, resulting in reduced vibration transmission to the user, and the mounting mechanisms can be noisy.
Innovation Solution
An adjustable bed base with an articulated deck and a pocket system that secures a vibratory motor within a cavity formed by opposing panels, using sound absorption materials and a support strap to minimize vibration transfer and noise, allowing for effective transmission of massage actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the massage motor is rigidly mounted to the underside of the headboard or footboard, then the motor is securely positioned, but the vibration is substantially attenuated by the thick foam mattress base and the resulting vibration applied to the user is less than desired
Solution Approach 1:
A resonator board is introduced as an intermediary component between the massage motor and the mattress base. The resonator board is rigidly mounted to the headboard or footboard and extends through the mattress base to transmit vibrations more effectively to the user, acting as a mediator that overcomes the attenuation caused by the foam mattress base.
Solution Approach 2:
The mounting structure uses a composite approach by combining the resonator board (rigid material) with the foam mattress base (soft material). The resonator board provides a rigid pathway for vibration transmission while the foam base provides comfort and support, creating a composite system that achieves both comfort and effective vibration transmission.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enhances the transmission of massage vibrations to the user while reducing noise, providing a more comfortable and quieter experience.
Implementation Method 1
the resonator board is then bonded to an interior surface within the slit in the mattress base, and the massage motor extends downward through the cutout in the mattress base... the vibrating action of the massage motor
Implementation Method 2
The pocket is made of polyester fill material with a cover made of nonwoven polyester fabric... secured to a lower surface of the at least one of the support sections underneath the opening

AI summary
An adjustable bed (10) includes an adjustable bed base (12) for supporting a mattress (14). The adjustable bed base (12) comprises an articulated deck (50) comprising head, seat, leg and foot deck boards (54, 56, 58, 58) hingedly joined together and supported from a frame (32). At least one of the support sections has an opening (72, 74) and a pocket (86) secured underneath the opening. Inside the pocket (86) is located a vibratory motor (100), the vibratory motor (100) being electrically coupled to a powered drive unit (66) for vibrating a portion of the adjustable bed (10).
