Buffered Stylus Shock Absorption via Elastic Staff
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional touch styluses with springs to absorb shock force increase production complexity and cost, leading to longer production times.
Innovation Solution
A buffered stylus design featuring a barrel and staff with an elastically deformable segment, such as a series of ring elements or a wavy segment, that extends and contracts to absorb shock force, simplifying the structure and reducing production time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a spring is incorporated into the stylus to absorb shock force, then the shock absorption capability is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent removes the separate spring component from the stylus structure and extracts only the essential shock absorption function, integrating it directly into the staff body through an elastically deformable segment. This eliminates the need for a distinct spring part while maintaining the shock absorption capability.
Solution Approach 2:
The patent combines the shock absorption function with the staff body structure by incorporating an elastically deformable segment directly into the staff. This merges previously separate components (spring and staff) into a unified structure, reducing overall device complexity.
2Reliability
If a spring is incorporated into the stylus to absorb shock force, then the shock absorption capability is improved, but the production time increases
Solution Approach 1:
By merging the shock absorption function into the staff body through an integrated elastically deformable segment, the patent eliminates the need for separate assembly steps for installing a spring component, thereby reducing production time and improving manufacturing efficiency.
Solution Approach 2:
The patent removes the separate spring component and its associated assembly procedures, extracting only the essential elastic deformation function and implementing it through a simplified integrated structure that requires fewer manufacturing and assembly steps.
3Reliability
If a spring is incorporated into the stylus to absorb shock force, then the shock absorption capability is improved, but the manufacturing cost increases
Solution Approach 1:
The patent combines the shock absorption function with the existing staff body structure, eliminating the need to manufacture and purchase separate spring components. This integration reduces part count, simplifies the bill of materials, and lowers overall manufacturing cost.
Solution Approach 2:
The patent removes the separate spring component from the bill of materials and manufacturing process, extracting only the essential elastic function and implementing it through a cost-effective integrated structure that reduces material and labor costs.
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 elastically deformable segment effectively reduces shock force on touch screens while maintaining a simple structure, thereby lowering production costs and time.
Implementation Method 1
The staff body portion has an elastically deformable segment that is capable of being extended and contracted in a longitudinal direction so as to absorb shock force

AI summary
A buffered stylus includes a barrel that has a first end and a second end opposite to the first end, and a staff that extends through the barrel. A front end portion of the staff has a part that extends outwardly of the first end of the barrel, and further has a rear end. A staff body portion is connected to the rear end of the front end portion, and has an elastically deformable segment capable of being extended and contracted in a longitudinal direction so as to absorb shock force. A rear end portion of the staff is connected to a rear end of the staff body portion, and is secured to the second end of the barrel.
