Magnetic Threaded Massage Head Attachment Against Vibration Loosening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Therapeutic treatment or massage devices with interchangeable components face complexity in attachment mechanisms and risk of components coming loose due to vibrations during use.
Innovation Solution
A magnetic attachment system comprising a treatment member with a magnet recess and a female attachment member internally threaded and secured with a shaft, providing a secure magnetic attraction and threading mechanism to stabilize the treatment member on the shaft.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a magnetic attachment system is used, then the treatment member is securely held during vibration, but the attachment mechanism becomes more complex
Solution Approach 1:
The patent combines multiple attachment mechanisms (magnetic attraction, threading, and snap-fit) into a single integrated attachment system. The female attachment member includes both a magnet for initial alignment and holding, and threaded portions for mechanical interlocking, thereby achieving secure attachment during vibration while maintaining reasonable complexity through functional integration.
2Reliability
If a secure attachment mechanism is used, then components remain stable during vibration, but the attachment and detachment process becomes more difficult
Solution Approach 1:
The attachment system is segmented into distinct functional zones: a magnet section for initial attraction and alignment, a threaded section for mechanical interlocking, and a snap-fit section for final securing. This segmentation allows each zone to perform its specific function optimally while enabling relatively easy attachment and detachment through a standardized sequence of operations.
3Reliability
If threading is added to secure the treatment member, then the attachment becomes more reliable, but the device complexity increases
Solution Approach 1:
The female attachment member is designed as a universal component that performs multiple functions: it provides magnetic attraction for initial alignment, contains threaded portions for mechanical interlocking, and includes snap-fit features for final securing. This multi-functionality reduces the need for separate components, thereby increasing reliability while controlling overall complexity through a single integrated attachment member.
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 system effectively secures treatment members to the shaft, preventing loosening during use and simplifying the attachment process, allowing for easy interchange of components.
Implementation Method 1
a magnet is disposed within the attachment recess, whereby when the shaft is received in the attachment recess a distal end of the shaft is magnetically attracted to the magnet
Implementation Method 2
the female attachment member is internally threaded, and wherein the female attachment member is configured to mate with external threads of the shaft
