Replaceable Conductive Marker Tip with Antenna for Paper-Like Writing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pen-styluses lack the ability to provide a high-quality writing experience similar to using a pen or pencil on paper, and their compatibility with digitizers is often limited, restricting their precision and functionality.
Innovation Solution
A removable marker tip for an active pen-stylus that integrates an antenna and insulator, translating physical forces into electronic signals for enhanced interaction with a tablet device, mimicking the sensations of writing on paper.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an antenna is integrated into the marker tip to enable active communication with the digitizer, then compatibility and precision are improved, but the writing sensation quality deteriorates
Solution Approach 1:
The marker tip is divided into separate functional components: a conductive core for antenna functionality and an insulating outer layer for paper emulation. This segmentation allows each component to optimize its specific function without compromising the other, resolving the contradiction between antenna performance and writing sensation quality.
Solution Approach 2:
The marker tip uses a composite structure combining conductive material (for antenna operation) with insulating material (for paper-like writing sensation). This composite approach enables simultaneous achievement of electrical functionality and tactile authenticity, directly addressing the technical contradiction.
2Ease of operation
If conventional marker tips are used without integrated electronics, then the writing sensation is authentic, but compatibility with advanced digitizers is limited
Solution Approach 1:
The invention merges the traditional paper-emulation marker tip structure with active electronic components (antenna, force sensor) to create a hybrid device. This combination enables the marker tip to simultaneously provide authentic writing sensation and advanced digital compatibility, resolving the contradiction between authenticity and adaptability.
Solution Approach 2:
The marker tip is designed to perform multiple functions: it emulates paper texture for writing sensation, contains an antenna for wireless communication, and includes force sensing capability. This multi-functionality allows a single component to address both conventional and advanced requirements, enhancing universality and compatibility.
3Reliability
If the marker tip is made replaceable to maintain optimal performance, then reliability is improved, but device complexity increases
Solution Approach 1:
The antenna and force sensor components are extracted from the main pen body and placed in replaceable marker tips. This extraction allows the expensive electronic components to be replaced independently when worn, maintaining system reliability without requiring replacement of the entire pen, thus managing complexity effectively.
Solution Approach 2:
The design enables discarding of worn marker tips while recovering and retaining the expensive pen body and electronic components. This selective replacement strategy improves reliability by ensuring optimal performance components are always available, while managing overall system complexity through modular architecture.

AI summary
Embodiments of the invention provide a removable marker tip configured for application with an active pen-stylus. The removable marker tip comprises an antenna and an insulator and is designed to be held onto the pen-stylus' writing shaft by a set of crush ribs fitted into a posterior recess on the removable marker tip. The removable marker tip is designed to be a consumable part to improve the paper feeling received by users of the pen-stylus as they draw on the display of a tablet device. The removable marker tip is further designed to be hand-removable by users of the pen-stylus.
