Solution Overview

Problem

Existing methods for searching handwritten memo data on mobile devices are time-consuming and inconvenient, often producing poor results due to the need for users to manually compare character-recognizable keywords or image patterns in stored memo files.

Innovation Solution

A method and apparatus that convert handwritten memo data into bit streams representing continuous and discontinuous elements, allowing for efficient storage and search within a memo index database, enabling quick retrieval of matching data regardless of orientation or size.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If users manually compare character-recognizable keywords or image patterns in stored memo files, then search functionality is provided, but search time increases and search accuracy decreases

Engineering Contradiction:

Improvesearch functionalityVSAvoidsearch time

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The patent applies preliminary action by converting handwritten memo data into bit stream format and storing it in a database before search operations are needed. This pre-processing transformation enables rapid retrieval during actual search operations, eliminating the time-consuming manual comparison process while maintaining search functionality.

Inventive Principle:

Principle #10Preliminary action

2Ease of operation

If users manually compare character-recognizable keywords or image patterns in stored memo files, then search functionality is provided, but search accuracy decreases

Engineering Contradiction:

Improvesearch functionalityVSAvoidsearch accuracy

Core Design Contradiction:

Ease of operationVSMeasurement precision

Solution Approach 1:

The patent replaces the mechanical manual comparison process with an automated bit stream-based search system. By converting handwritten data into standardized bit stream representations and implementing automated database search algorithms, the system achieves higher search accuracy without requiring manual intervention, thereby resolving the contradiction between ease of operation and search precision.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Quantity of substance

If handwritten memo data is stored in traditional file formats, then data is stored, but search efficiency decreases

Engineering Contradiction:

Improvedata storageVSAvoidsearch efficiency

Core Design Contradiction:

Quantity of substanceVSProductivity

Solution Approach 1:

The patent applies parameter changes by transforming the storage format of handwritten memo data from traditional file formats to bit stream representation. This fundamental change in data structure and format enables efficient database operations and rapid retrieval, significantly improving search efficiency while maintaining the ability to store large quantities of memo data.

Inventive Principle:

AI summary

A method and apparatus for storing and searching for handwritten memo data in a database in which the handwritten memo data are stored in the form of bit streams representing continuous and discontinuous elements constituting the handwritten memo data are provided. The memo data search method includes receiving an input of memo data, storing the memo data in the form of a bit stream, searching, when a search for the memo data is requested, a memo index database for the memo data, and displaying a search result. The handwritten memo data management method and apparatus stores and searches for the memo data regardless of orientation and size.
