Problem

Existing Chinese character input methods, such as Wubi shape input, are messy, difficult to learn, have high repetition rates, slow input speeds, and require specific learning and equipment conditions.

Innovation Solution

A Chinese character input method and system that uses component and stroke category codes to represent characters, allowing intuitive input without complex rules, and includes a keyboard design that simplifies learning and enhances input speed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If Wubi shape input method is used, then character input capability is achieved, but the rules are very complicated and learning is difficult

Engineering Contradiction:

Improvelearning difficultyVSAvoidinput method rules

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent segments Chinese characters into basic components (radicals and strokes) and assigns each a category code. Users input characters by selecting from displayed components rather than memorizing complex encoding rules, thereby simplifying the input process while maintaining character input capability

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent creates a simplified representation of Chinese characters by copying and displaying their basic components (radicals and strokes) on screen. Users interact with these visual copies rather than dealing with abstract encoding rules, making the input method intuitive and easy to learn

Inventive Principle:

Principle #26Copying

2Productivity

If pinyin input method is used, then voice-based input is enabled, but the code repetition rate is high and input speed is slow

Engineering Contradiction:

Improveinput speedVSAvoidcode repetition rate

Core Design Contradiction:

ProductivityVSQuantity of substance

Solution Approach 1:

The patent segments characters into components with unique category codes. By organizing components hierarchically and displaying relevant options, the system reduces code repetition and allows faster character selection compared to pinyin's high repetition rate

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent implements feedback by displaying the basic components corresponding to the input category codes in real-time. This visual feedback allows users to confirm and select characters more efficiently, improving input speed while reducing unnecessary code repetitions

Inventive Principle:

Principle #23Feedback

3Productivity

If handwriting input method is used, then direct character input is possible, but the speed is slow and it is limited by hardware input device

Engineering Contradiction:

Improveinput speedVSAvoidhardware dependency

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The patent replaces the mechanical handwriting input process with a keyboard-based component selection system. Instead of requiring specialized handwriting recognition hardware, the system uses standard keyboards to input category codes and displays components for selection, eliminating hardware limitations while improving speed

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

4Ease of operation

If voice input method is used, then spoken character input is enabled, but high requirements for pronunciation accuracy, hardware and software equipment are imposed

Engineering Contradiction:

Improveinput accessibilityVSAvoidequipment requirements

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces complex voice recognition hardware and software systems with a simple keyboard input mechanism. Users type category codes corresponding to character components, eliminating the need for specialized voice input equipment while maintaining accessibility

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent uses standard, widely available keyboard inputs instead of expensive, specialized voice recognition equipment. This approach reduces equipment requirements and makes the input method accessible to ordinary users without investing in specialized hardware

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

AI summary

The invention discloses a Chinese character input method, system and a keyboard, and relates to the technical field of computers. A specific implementation of the method includes: recognizing the received key signal; in the case where the recognition result of the received key signal indicates a Chinese character Category Code and/or phrase Category Code, determining the recognized Chinese character and/or phrase represented by the Chinese character Category Code and/or the phrase Category Code; where the Chinese character Category Code is a combination of component Category Codes or a combination of component Category Codes and stroke Category Codes, used to represent Chinese characters; phrase Category Codes are combinations of component Category Codes, used to indicate phrases; display the determined Chinese characters and/or phrases. This implementation method solves the problem of messy character splitting, conforms to the character theory, is easy to remember and easy to use, does not require special learning. The entire input process is very natural, there are not many rules, the learning difficulty is reduced, and there are no special requirements for equipment conditions.
