Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional massage beds with vibration motors have limited vibration transmission due to fixed installation and complex assembly processes, which hinder effective massage performance and user comfort.
Innovation Solution
A modular bed design featuring a frame assembly, elongated support units, and a vibration assembly with a rack, stretchable web, and vibration motor, where the vibration motor is detachably mounted on the support units, allowing for improved vibration distribution and easier installation by using a stretchable web to suspend the motor and enhance vibration transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vibration motor is fixedly secured to the support panel by screws, then the motor is firmly attached, but the transmission of vibration from the motor to the bed mattress is limited
Solution Approach 1:
The patent introduces a vibration transmission component as an intermediary between the vibration motor and the support panel. This component is specifically designed to couple the motor to the support panel in a manner that enhances vibration transmission, allowing the motor's vibrational energy to be more effectively transferred to the bed mattress for massage purposes
Solution Approach 2:
The patent modifies the coupling parameters between the motor and support panel by using a specialized vibration transmission component rather than conventional screw fixation. This changes the mechanical coupling characteristics to optimize vibration transmission while maintaining secure attachment
2Reliability
If the vibration motor is fixedly secured in a through hole of the support panel, then the motor is firmly attached, but the installation process becomes relatively complicated
Solution Approach 1:
The patent divides the motor assembly into separate modular components including the vibration motor, vibration transmission component, and positioning structure. This segmentation allows each component to be independently manufactured and assembled, simplifying the overall installation process while maintaining secure attachment
Solution Approach 2:
The patent employs a positioning plate with positioning holes that can be selectively aligned with positioning protrusions on the support panel. This dynamic positioning system allows for flexible installation at different locations and simplifies the assembly process by enabling easy alignment and attachment without complex fixed positioning mechanisms
3Device complexity
If the vibration motor is positioned at a fixed location, then the motor structure is simple, but the vibration distribution to different areas of the bed mattress is limited
Solution Approach 1:
The patent implements a dynamic positioning system where the vibration motor can be located at different positions on the support panel by aligning the positioning plate with different positioning protrusions. This allows the motor to be positioned to provide optimal vibration distribution to different areas of the bed mattress while maintaining a simple overall structure
Solution Approach 2:
The positioning system is designed with multiple positioning protrusions distributed at different locations on the support panel, allowing the same vibration motor assembly to serve multiple positioning functions. This multi-position capability enables versatile vibration distribution coverage across different areas of the bed mattress without requiring multiple different motor assemblies
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 modular bed design enhances vibration transmission and user comfort by allowing the vibration motor to be positioned optimally and simplifies the installation process, providing a more effective massage experience while being convenient for storage and transportation.
Implementation Method 1
The vibration motor includes a motor body, a positioning plate which has a dimension larger than a dimension of the through bore, and a neck portion which is coupled between the motor body and the positioning plate such that after the through bore is stretched to permit the positioning plate to be inserted through the stretched through bore, resilient retraction of the through bore causes the neck portion to be trapped in the through bore with the motor body and the positioning plate to be in abutting engagement with the upper and lower surfaces of the stretchable web, respectively

AI summary
A modular bed includes a frame assembly, a plurality of elongated support units, and at least one vibration assembly including a rack, a stretchable web, and a vibration motor. The rack is detachably mounted on two selected adjacent ones of the elongated support units. The stretchable web has a central portion suspended across a lower opening of the rack. After the through bore is stretched to permit insertion of a positioning plate of the vibration motor, resilient retraction of the through bore causes a neck portion of the vibration motor to be trapped in the through bore with a motor body and the positioning plate of the vibration motor to be in abutting engagement with upper and lower surfaces of the stretchable web, respectively.
