Keyboard Layout with Vowel Grouping and Consonant Ordering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing keyboard layouts, such as QWERTY and Dvorak, are difficult for beginners to learn due to their random arrangement of letters, which wastes time and effort in training, despite their focus on typing speed rather than ease of use.
Innovation Solution
A keyboard layout with 10-9-7 keys per row, where vowels are grouped and color-coded on the left, and consonants are arranged in alphabetical order across the keyboard, making it easier to identify letter positions based on the Roman alphabet sequence.

Engineering Contradiction Analysis
1Speed
If the QWERTY keyboard layout is used to slow down typing speed for mechanical typewriters, then typing speed is reduced, but the keyboard becomes difficult to learn with no consideration for ease of learning
Solution Approach 1:
The keyboard is segmented into three distinct rows (home row, top row, bottom row) with specific functional assignments. The home row contains all vowels and commonly used consonants, allowing fingers to rest and type frequently used letters without moving to other rows, thereby maintaining speed while improving learnability through systematic organization.
Solution Approach 2:
The most frequently used letters (vowels and common consonants) are pre-positioned on the home row where fingers naturally rest. This preliminary arrangement eliminates the need for finger movement for common letters, making the keyboard intuitive to learn while maintaining high typing speed.
2Speed
If the Dvorak keyboard layout is used to increase typing speed by measuring operator distance, then typing speed is improved, but the keyboard remains difficult to learn with random arrangement requiring extensive practice
Solution Approach 1:
Different rows have different functional qualities: the home row is dedicated to vowels and common consonants for frequent use, the top row contains less frequent letters, and the bottom row contains remaining letters. This local differentiation allows fingers to operate efficiently in their respective zones while making the layout intuitive through functional organization rather than random arrangement.
Solution Approach 2:
The keyboard introduces a vertical dimension to letter arrangement by organizing letters across three rows based on frequency and finger assignment, rather than just horizontal sequences. This dimensional organization creates a logical spatial relationship that is easier to learn while maintaining speed efficiency.
3Speed
If traditional keyboard layouts arrange letters in random sequences optimized for speed, then typing speed may be improved, but learning time increases significantly requiring weeks or months of training
Solution Approach 1:
The keyboard changes the arrangement parameter from random or speed-optimized sequences to a frequency-based hierarchical arrangement across three rows. This parameter change organizes letters by usage frequency and finger assignment, creating a logical structure that reduces learning complexity while maintaining typing speed.

AI summary
An apparatus for entering alphabetic data into a computer or other electronic or mechanical devices with a keyboard, wherein: the alphabet letters are placed in an ordered arrangement, the vowels are grouped together, the vowels are all placed on the left side of the keyboard, each vowel has the same color code, the consonants are arranged in groups, the consonant groups are arranged from left to right in alphabetic group order, each consonant group has a specific color code, two groups of consonants have the same color, and letters in each consonant group are arranged vertically across the three rows of the keyboard, with the exception of the JK consonant group which is arranged horizontally on a single row of the keys.
