Solution Overview

Problem

Current data entry methods, such as QWERTY keyboards and touch-screen devices, are often tedious, time-consuming, and illogical, especially when trying to input common symbols like letters and numbers, due to the complexity and organization of keys.

Innovation Solution

A novel user interface (UI) system that uses a data entry device with a limited number of keys, allowing users to input symbols by activating cells associated with matrices, enabling single-click or double-click input of eight symbols, with a processor to receive user input, and a 'thumb device' design for quick and accurate typing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a QWERTY keyboard is used for data entry, then a wide variety of symbols can be input, but the system becomes complex and time-consuming to use

Engineering Contradiction:
Improvesymbol input capabilityVSAvoidkeyboard complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The keyboard is segmented into functional groups (number row, letter rows, symbol rows) that can be independently activated. Each key has a primary function and can access secondary functions through combination modes, reducing the need for a separate key for every possible symbol input scenario.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Each key on the keyboard is designed to perform multiple functions. By using shift keys and combination modes, a single key can access multiple symbols and characters, reducing the total number of keys needed while maintaining comprehensive symbol input capability.

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

2Adaptability or versatility

If a QWERTY keyboard with many keys is used, then various symbols can be input, but the data entry process becomes time-consuming

Engineering Contradiction:
Improvesymbol input capabilityVSAvoiddata entry speed
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The keyboard provides direct access to commonly used symbols through the number row and frequently used keys. Frequently accessed symbols are positioned in locations that require minimal finger movement, and shift key combinations are designed to access common symbols in predictable patterns, reducing the time needed to locate and input symbols.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

Different regions of the keyboard are optimized for different types of symbol input. The number row provides direct numeric input, letter rows provide alphabetic input, and specific keys provide direct access to commonly used symbols. This spatial organization allows users to access different symbol types from their most convenient locations without traversing the entire keyboard.

Inventive Principle:
Principle #3Local quality

3Device complexity

If a television data entry system with limited keys is used, then the device complexity is reduced, but the data entry process becomes tedious and time-consuming

Engineering Contradiction:
Improvekeyboard simplicityVSAvoiddata entry speed
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The keyboard merges multiple functions into fewer keys through the use of shift keys and combination modes. Instead of having separate keys for each symbol, the system combines symbol access with letter and number keys, allowing a single key press to access multiple symbol types depending on the active mode.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The keyboard implements dynamic key functionality where keys can change their output based on combination modes. The shift keys and mode indicators dynamically alter the function of other keys, allowing the same physical key to produce different symbols based on the current keyboard state, thereby reducing the total number of keys needed.

Inventive Principle:
Principle #15Dynamics

4Adaptability or versatility

If a keyboard with many keys is used, then comprehensive symbol input is possible, but the ease of operation decreases

Engineering Contradiction:
Improvesymbol input capabilityVSAvoidkeyboard usability
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The keyboard implements a nested structure where shift keys and combination modes create layers of functionality. A single key press can access basic symbols, while combining with shift keys or using combination modes accesses additional symbol layers, all controlled from a compact key set that fits comfortably on a television remote.

Inventive Principle:
Principle #7Nested doll (Nesting)

AI summary

A data entry system is disclosed. Some embodiments of the data entry system utilize an input device and a user interface. In some embodiments, a user can actuate keys on an input device to activate and/or select from the user interface cells associated with symbols, such as letters. A user can input different symbols quickly and efficiently. In some embodiments, users can input the most common letters of a given alphabet using only a single actuation of one of four keys.
