Stylus Pen Positioning Module Tactile Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Retractable stylus pens lack a noticeable positioning feel when retracted, affecting user experience due to their thin and short design.
Innovation Solution
A stylus pen design featuring a rod body, cover body, and positioning module that generates force changes along a second axial direction when the cover body moves between positions, providing a tactile positioning feel through engaging structures and magnetic interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the stylus pen is designed to be thin and short for portability, then the ease of carrying is improved, but the positioning feel during retraction deteriorates
Solution Approach 1:
The stylus pen is divided into multiple functional segments: a rod body containing the writing tip, a cover body for protection, and a positioning module with engaging structures. This segmentation allows each component to have specialized functions, with the positioning module specifically designed to provide tactile feedback during retraction despite the overall compact size.
Solution Approach 2:
The positioning module acts as an intermediary mechanism between the cover body and rod body. It includes engaging structures with elastic arms that interact with corresponding features on the rod body to generate positioning forces, providing tactile feedback without requiring the stylus to be long or complex.
2Length of moving object
If the stylus pen is made retractable to improve portability, then the ease of carrying is improved, but the wear on moving parts increases
Solution Approach 1:
The positioning module is designed to absorb and distribute mechanical stresses before they can cause damage to the moving parts. The elastic arms in the engaging structures act as cushioning elements that deform elastically during engagement and disengagement, reducing impact forces and wear on the connecting components.
Solution Approach 2:
The engaging structures utilize flexible elastic arms that can bend and deform during the retraction and extension movements. This flexibility allows the positioning module to accommodate movement variations and reduce stress concentrations, thereby minimizing wear on the mechanical components and extending the service life of the stylus pen.

AI summary
A stylus pen includes a rod body, a cover body, and a positioning module. The rod body includes a main body portion and a sleeve portion connected to each other. The cover body is configured to be sleeved onto the sleeve portion, and is configured to move relative to the rod body to a first position and a second position along a first axial direction. The positioning module is disposed between the sleeve portion and the cover body, and is configured to generate changes of force to the cover body and the rod body in a second axial direction when the cover body moves to the first position and the second position relative to the rod body.
