Stylus Head Mounting via Limiting Portion and Fixing Rod
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing interactive device styluses have an unstable structure due to loose fitting of the stylus head, leading to frequent loosening and fall-off, which negatively impacts user experience.
Innovation Solution
The design includes a stylus body with a stylus cap and head, where the stylus head is fixed via a connecting piece with a limiting portion and a fixing rod, and further enhanced by NFC chips, a supporting column, and thread connections for improved stability and customization, along with a limiting foam and LED light for usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the stylus head is directly fitted to the stylus body, then the structure is simple, but the mounting stability is poor leading to frequent loosening and fall-off
Solution Approach 1:
The patent introduces a connecting piece as an intermediate component between the stylus head and stylus body, dividing the mounting structure into separate segments. This connecting piece includes a limiting portion with a through-hole that engages with the stylus head, while the other end connects to the stylus body, thereby improving mounting stability without excessively complicating the overall structure.
Solution Approach 2:
The connecting piece serves as an intermediary element that mediates the connection between the stylus head and stylus body. It provides a stable mounting interface through its limiting portion and through-hole design, preventing direct contact and potential instability between the stylus head and body while maintaining structural simplicity.
2Reliability
If a limiting portion with through-hole is added to engage the stylus head, then the mounting stability is improved, but the device complexity increases
Solution Approach 1:
The connecting piece is designed as a separate segmented component with a limiting portion and through-hole, rather than integrating these features directly into the stylus body. This segmentation allows for improved mounting stability through the engaging structure while keeping the overall device complexity manageable by using a dedicated intermediate component.
Solution Approach 2:
The connecting piece performs multiple functions: it provides mechanical engagement through the limiting portion, allows for NFC chip integration, and serves as a structural bridge between the stylus head and body. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in device complexity while achieving improved mounting stability.
3Adaptability or versatility
If NFC chips and supporting columns are added, then the functionality and customization are enhanced, but the device complexity increases
Solution Approach 1:
The connecting piece is designed to accommodate NFC chips and support supporting columns, allowing a single component to perform multiple functions including mechanical engagement, wireless communication, and structural support. This multi-functionality enhances adaptability and customization while minimizing the increase in device complexity by avoiding the need for separate dedicated components for each function.
Solution Approach 2:
The patent merges the NFC chip and supporting column functions into the connecting piece structure. By combining these functional elements into the existing intermediate component rather than adding them as separate assemblies, the patent enhances functionality and customization options while controlling the overall device complexity.

AI summary
An interactive device stylus includes a stylus body, a stylus cap disposed at a front end of the stylus body, and a stylus head disposed on the stylus cap. The stylus head is fixed to a front end of the stylus cap via a connecting piece, a through-hole is provided in the connecting piece, and the inner diameter of the through-hole gradually decreases from the inside of the connecting piece to a free end of the connecting piece, so that a limiting portion is formed at the free end of the connecting piece. The stylus head is engaged in the connecting piece via the limiting portion. A fixing rod is provided in the stylus cap, and an end of the fixing rod is pressed against the stylus head.
