Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Entering logograms such as Chinese characters can be difficult due to their complexity and the large number of possible characters, making it challenging for users to find the correct character when only a portion of it is input.

Innovation Solution

An apparatus and method that utilize a combination of a written input device and an audio input device, processing the input to detect sub-logograms and pronunciations, and displaying logogram hints that include both the sub-logogram and pronunciation, allowing users to select the correct logogram more easily.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If users input only a portion of a logogram, then the search results include many possible logograms, but it becomes difficult to identify the correct logogram quickly

Engineering Contradiction:

Improvenumber of logogram optionsVSAvoidease of identifying correct logogram

Core Design Contradiction:

Quantity of substanceVSEase of operation

Solution Approach 1:

The patent introduces an intermediary element - the pronunciation audio signal - that mediates between the partial written input and the complete logogram identification. The system uses this intermediate pronunciation information to filter and narrow down the list of possible logograms, making it easier for users to identify the correct character without requiring complete input.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If the system displays all possible logograms matching partial input, then completeness is maintained, but the time to select the correct logogram increases

Engineering Contradiction:

Improvecompleteness of logogram optionsVSAvoidtime to select correct logogram

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary action by pre-processing the partial written input to extract pronunciation information before displaying results. By preparing and filtering the logogram list in advance based on the extracted pronunciation, the system reduces the time users need to spend manually searching through complete lists of matching characters.

Inventive Principle:

Principle #10Preliminary action

3Device complexity

If the system uses only written input, then the device complexity is low, but the accuracy of logogram identification decreases

Engineering Contradiction:

Improvecomplexity of input processingVSAvoidaccuracy of logogram identification

Core Design Contradiction:

Device complexityVSMeasurement precision

Solution Approach 1:

The patent merges multiple input modalities - written input and audio input - into a unified processing system. By combining these different types of input signals, the system achieves higher accuracy in logogram identification while managing device complexity through integrated processing of multiple signal types.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

For detecting logograms using multiple inputs, code executable by a processor may detect a sub-logogram from a written input to a written input device, detect a pronunciation from an audio input to an audio input device, and display one or more logogram hints in response to detecting the sub-logogram and the pronunciation. Each logogram hint of the one or more logogram hints includes the sub-logogram.
