Solution Overview

Problem

Current Chinese input methods using Pinyin on Western keyboards face inefficiencies due to syllable boundary confusion and complexity when representing tones, leading to increased selection time and difficulty in learning, especially with the HLV Pinyin input system's use of inappropriate letters for tone representation.

Innovation Solution

The method employs the keys j, q, and x to represent three of the four tones of Mandarin, with 'no entry' representing the remaining tone, allowing syllables and tones to be inputted without confusion, simplifying the input process and reducing code repetition.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the HLV Pinyin input system uses letters h, l, and v to represent tones, then tone representation is achieved, but syllable boundary confusion occurs

Engineering Contradiction:
Improvetone representationVSAvoidsyllable boundary clarity
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The patent extracts the tone representation function from the syllable spelling by using separate tone markers (h, l, v) that are appended after the syllable. This separation allows the syllable boundary to remain clear while still representing tones, as the tone markers are distinct from the syllable consonants and vowels.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces tone markers (h, l, v) as intermediary elements between the syllable spelling and the Chinese character selection. These markers serve as a bridge that conveys tone information without interfering with the syllable boundary identification, resolving the confusion between syllable structure and tone representation.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of information

If extra letters y, w, r and k are used to represent tones in different situations, then syllable boundary confusion is remedied, but input complexity increases

Engineering Contradiction:
Improvesyllable boundary clarityVSAvoidinput code complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent makes the tone markers (h, l, v) universal by using the same set of letters for all tone representations across different syllables and contexts. This multi-functionality eliminates the need for different letter sets for different situations, simplifying the input system while maintaining clear syllable boundaries.

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

Solution Approach 2:

The patent changes the parameter of tone representation from multiple letter sets to a single consistent set (h, l, v). By standardizing the tone markers across all situations, the system reduces complexity while maintaining unambiguous syllable boundary identification.

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If Pinyin input method is used without tones, then ease of learning is improved, but the number of Chinese character choices increases

Engineering Contradiction:
Improveease of learningVSAvoidinput speed
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The patent performs preliminary action by requiring users to input tone markers immediately after the syllable spelling. This preliminary tone specification reduces the number of character choices before the user needs to make a selection, thereby increasing input speed while maintaining the simplicity of Pinyin-based input.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent provides feedback by displaying the reduced character list based on the syllable and tone combination input. This feedback mechanism shows users the narrowed-down selection results, confirming that the tone information has been processed correctly and guiding the user to the desired character more quickly.

Inventive Principle:
Principle #23Feedback

4Reliability

If more than 240 radicals with basic codes are introduced, then repeated code problem is solved, but learning difficulty increases

Engineering Contradiction:
Improvecode uniquenessVSAvoidlearning difficulty
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent extracts the radical coding function from the tone representation system. By separating radical basic codes from tone markers, the system achieves unique code representation without increasing learning difficulty, as users only need to learn the tone markers (h, l, v) in addition to the existing Pinyin system.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent segments the input process into distinct components: syllable spelling, tone markers, and radical codes. This segmentation allows each component to be learned independently, reducing the overall learning burden while ensuring unique and reliable code representation for Chinese characters.

Inventive Principle:
Principle #1Segmentation

AI summary

This invention discloses a Chinese input method using Pinyin plus a new tone notation on a Western keyboard or keypad to input Chinese characters, characterized in that the user can input a Chinese compound word (polysyllabic word) containing several syllables and tones by just keying in a series of letters representing the syllables and tones of the word, and the letters are all joined together without causing any confusion. This feature is attributed to the new tone input method of this invention, which is characterized in that the three letters j, q and x are used to input three of the four tones of Putonghua (Mandarin), and “no entry” is used to input the remaining tone. There is a detailed logical reasoning in the specification of this patent application explaining how this method can achieve the feature of “syllables with tones are joined together without causing confusion”. Input of these syllables with tones via just a Western keyboard, together with the important feature of “the syllables with tones are joined together without causing confusion”, will have a major impact on the technical field of Chinese input method.
