Innovation Solution

An apparatus and method that includes a character input unit, character recognition unit, representative trace generation unit, and trace modification unit to receive and modify handwriting inputs by generating a representative trace and combining it with the input trace using weight values, allowing for the creation of personalized fonts based on the user's handwriting style.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a user inputs handwriting through a pen input device, then the user can transfer information using their own handwriting style, but the handwriting trace becomes uneven and noisy due to input device limitations and handwriting variability

Engineering Contradiction:

Improvehandwriting style expressionVSAvoidhandwriting trace quality

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The patent introduces a representative trace as an intermediary between the noisy input trace and the final output. The representative trace captures the essential characteristics of the user's handwriting style while filtering out noise and irregularities. This mediator allows the system to preserve the user's personal style while eliminating the harmful variability in the raw input trace.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent changes the parameter representation of the handwriting trace by extracting key features and representing them in a simplified form. Instead of using the raw coordinate data which contains noise, the system transforms the trace into a representative form that captures essential stylistic parameters while removing unwanted variability.

Inventive Principle:

Principle #35Parameter changes

2Manufacturing precision

If the user writes clearly, then the handwriting trace quality is good, but not all users can write clearly and some users have hand trembling or poor input device sensitivity

Engineering Contradiction:

Improvehandwriting trace qualityVSAvoiduser writing effort

Core Design Contradiction:

Manufacturing precisionVSEase of operation

Solution Approach 1:

The system performs self-correction by automatically processing the input trace to generate a representative trace. The algorithm independently identifies and corrects noise, irregularities, and inconsistencies in the handwriting trace without requiring the user to rewrite or correct their handwriting. This self-service approach maintains ease of operation while improving trace quality.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent converts the harmful noise and variability in the input trace into beneficial information. By analyzing the variations in the raw handwriting trace, the system extracts meaningful stylistic characteristics that define the user's personal handwriting style, transforming what was previously harmful noise into useful data for personalization.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

3Productivity

If the system uses the raw input trace directly, then the process is simple, but the output lacks elegance and user satisfaction

Engineering Contradiction:

Improvefont generation speedVSAvoidfont quality

Core Design Contradiction:

ProductivityVSManufacturing precision

Solution Approach 1:

The patent performs preliminary processing of the input trace by generating a representative trace before final font creation. This preliminary action of extracting essential characteristics and removing noise early in the process simplifies subsequent processing steps while ensuring high-quality output. The representative trace serves as a refined foundation for generating elegant fonts.

Inventive Principle:

Principle #10Preliminary action
