Solution Overview

Problem

Character recognition devices face inefficiencies in processing time and user convenience due to the need to restrict character size for recognition, leading to unrecognized characters if the user is unaware of the recognized size, and existing solutions do not effectively balance processing speed with user awareness of recognition parameters.

Innovation Solution

A character recognition device with a configuration that includes a camera, storage, and processing unit, which displays the recognition size and area parameters to the user, allowing dynamic adjustment of these parameters through touch operations, ensuring characters within a defined size range are recognized efficiently.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If character recognition is restricted to specific size ranges, then processing time is reduced, but characters outside the restricted size range cannot be recognized

Engineering Contradiction:
Improveprocessing timeVSAvoidcharacter size recognition range
Core Design Contradiction:
Loss of timeVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamic adjustment of recognition parameters by allowing users to modify character size ranges and recognition areas through touch operations. The system transitions from static fixed-size recognition to dynamic adaptive recognition, resolving the contradiction between processing speed and recognition versatility.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system enables users to change recognition parameters (character size ranges, recognition area) according to different needs. By making parameters adjustable rather than fixed, the system can optimize between processing speed and recognition coverage based on specific usage scenarios.

Inventive Principle:
Principle #35Parameter changes

2Productivity

If recognition parameters are restricted to reduce processing time, then processing speed improves, but user convenience deteriorates due to lack of awareness about recognized characters

Engineering Contradiction:
Improveprocessing speedVSAvoiduser convenience
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The patent implements feedback mechanisms by displaying recognition results, recognized character sizes, and recognition areas to users. This transparency allows users to understand what is being recognized and adjust parameters accordingly, improving convenience while maintaining processing efficiency.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

Users can independently adjust recognition parameters and immediately see the effects through displayed recognition results. The system empowers users to optimize recognition settings for their specific needs without requiring technical assistance, enhancing ease of operation.

Inventive Principle:
Principle #25Self-service

3Reliability

If all characters in an image are recognized, then complete character coverage is achieved, but processing time increases significantly

Engineering Contradiction:
Improvecharacter recognition completenessVSAvoidprocessing time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent implements local quality by allowing users to define specific recognition areas within the image and set size ranges appropriate for different regions. Instead of uniform recognition across the entire image, the system applies targeted recognition to specific areas, reducing processing time while maintaining completeness for relevant characters.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system segments the recognition task by dividing the image into specific recognition areas and applying size-based filtering. This segmentation approach processes only relevant portions of the image, achieving complete coverage of target characters while excluding unnecessary processing of irrelevant regions.

Inventive Principle:
Principle #1Segmentation
