Solution Overview

Problem

Users who prefer writing with physical pens and ink face inconvenience in storing and recovering handwriting, as it requires additional procedures like scanning or photographing, making it difficult to preserve and record physical handwriting.

Innovation Solution

An ink-type pointer with a housing, circuit unit, pen and ink writing module, and electromagnetic unit that allows for digital handwriting capture while physically writing, using a cartridge, nib, and liquid ink, along with a magnet and coil for electromagnetic induction, enabling simultaneous physical writing and digital recording.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If physical pen and ink are used for writing, then the writing experience is authentic and familiar, but the storage and recovery of handwriting becomes inconvenient and requires additional procedures

Engineering Contradiction:
Improveconvenience of handwriting storageVSAvoidcomplexity of storage procedure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent combines the physical writing function (pen and ink) with the digital recording function (electromagnetic induction unit) into a single integrated pointer device. The cartridge with nib and liquid ink provides authentic writing experience, while the electromagnetic unit simultaneously captures handwriting digitally, merging two previously separate functions into one device.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The pointer serves multiple functions: it acts as both a traditional writing instrument (pen with cartridge and nib) and a digital recording device (electromagnetic induction unit). This multi-functionality allows users to write physically while simultaneously capturing digital handwriting, eliminating the need for separate scanning or photographing procedures.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Loss of information

If a scanner or photographing procedure is used to store handwriting, then the handwriting can be preserved digitally, but the process becomes time-consuming and complex

Engineering Contradiction:
Improvepreservation of handwritingVSAvoidtime for storage procedure
Core Design Contradiction:
Loss of informationVSLoss of time

Solution Approach 1:

The electromagnetic induction unit continuously captures and stores handwriting data in real-time during the writing process itself. This preliminary action of digital recording occurs simultaneously with physical writing, eliminating the need for subsequent scanning or photographing steps that would otherwise be required to preserve the handwriting.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The pointer automatically performs the digital recording function without requiring additional user actions. As the user writes with the pen, the electromagnetic induction unit autonomously captures the handwriting data and stores it digitally, making the preservation process automatic and eliminating manual intervention for storage.

Inventive Principle:
Principle #25Self-service

3Reliability

If paper with physical handwriting is lost, then the handwriting cannot be easily recovered

Engineering Contradiction:
Improvereliability of handwriting recoveryVSAvoidsystem structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The electromagnetic induction unit creates a digital copy of the physical handwriting in real-time. This digital copy is stored electronically and can be recovered even if the original paper is lost. The system maintains both the physical writing (for authentic experience) and a digital replica (for reliable recovery and storage).

Inventive Principle:
Principle #26Copying
