Pen Holding Device Dual Coupling Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pen holding devices for electronic devices often experience insecure coupling between the pen and the device, particularly due to weak magnetic coupling that allows for free orientation and potential detachment of the pen.
Innovation Solution
The implementation of a dual coupling mechanism that combines magnetic and frictional coupling to securely attach a pen to a pen holding device, utilizing a magnet and a pen clip holder to provide a stronger and more stable connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If magnetic coupling is used to attach the pen to the pen holding device, then the attachment is simple and allows for easy detachment, but the coupling strength is insufficient and allows for free orientation and potential accidental detachment
Solution Approach 1:
The patent combines magnetic coupling and frictional coupling mechanisms into a single integrated receiver assembly. The magnet provides initial attraction and easy detachment, while the pen clip holder provides frictional coupling to prevent free orientation and accidental detachment. This merging of two coupling mechanisms resolves the contradiction by maintaining ease of operation through magnetic attraction while improving reliability through the additional frictional constraint.
2Device complexity
If a single magnetic coupling mechanism is used, then the device structure is simple, but the pen can freely orient along the longitudinal axis and may be inadvertently detached
Solution Approach 1:
The receiver integrates both a magnet and a pen clip holder into a single assembly, combining magnetic coupling and frictional coupling functions. This merging approach maintains relatively simple device structure while significantly improving pen orientation stability by preventing free rotation along the longitudinal axis through the frictional constraint of the pen clip holder.
Solution Approach 2:
The coupling mechanism uses composite coupling approaches by combining two different physical coupling mechanisms (magnetic and frictional) within the same receiver structure. This composite approach allows the system to achieve both structural simplicity and orientation stability simultaneously.

Function Achieved in This Case
This dual coupling mechanism enhances the stability and security of the pen attachment, preventing accidental detachment and ensuring reliable interaction with electronic devices.
Implementation Method 1
The receiver can include a magnet to provide a magnetic coupling between the pen and the receiver
Implementation Method 2
a frictional coupling refers to a coupling between a pen and a pen holding device, in which the pen holding device is to, when coupled to the pen, limit movement of the pen within the pen holding device via a frictional force
