Innovation Solution

An alternative keyboard system that allows for tactile input on a reduced-sized device with defined areas for specific electronic inputs, enabling automatic text and command entry without visual interaction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a standard keyboard layout is used, then text input functionality is complete, but input speed is slow and device size is large

Engineering Contradiction:
Improveinput speedVSAvoiddevice size
Core Design Contradiction:
ProductivityVSLength of moving object

Solution Approach 1:

The keyboard is segmented into functional zones rather than individual character keys. The input surface is divided into regions for different input modes (text input, command input, navigation) that can be dynamically activated. This segmentation allows the device to provide full keyboard functionality in a compact form by presenting only the necessary input options at any given moment.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The keyboard layout is dynamic and reconfigurable based on the current input mode and context. The functional zones can be reassigned and reconfigured in real-time depending on whether the user is in text input mode, command input mode, or navigation mode. This dynamic adaptation allows the same physical surface to serve multiple functions without requiring a large static layout.

Inventive Principle:
Principle #15Dynamics

2Extent of automation

If visual interaction is required for input, then input accuracy is high, but user cannot perform simultaneous tasks

Engineering Contradiction:
Improvehands-free operation capabilityVSAvoidinput accuracy
Core Design Contradiction:
Extent of automationVSMeasurement precision

Solution Approach 1:

The system provides immediate tactile and visual feedback to confirm input registration without requiring visual verification of the entire keyboard layout. Haptic feedback mechanisms provide tactile confirmation when input zones are activated or when input is registered, allowing users to maintain accurate input while keeping their eyes on other tasks or the road.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system includes predictive text and automatic command completion features that reduce the precision required from the user. The system anticipates intended input based on context and partially completes it automatically, reducing the burden on the user while maintaining high input accuracy through automated assistance.

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If multiple input modes are supported, then system versatility is high, but interface complexity increases

Engineering Contradiction:
Improveinput mode flexibilityVSAvoidinterface complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

A single unified input surface serves multiple input modes (text input, command input, navigation) that would traditionally require separate physical interfaces. The same tactile surface can be configured for different functions based on the active mode, eliminating the need for multiple specialized input devices while maintaining full versatility.

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

Solution Approach 2:

The interface dynamically adapts its complexity based on the current mode. When in text input mode, the interface presents text-related options; when in command mode, it presents command-related options. This dynamic simplification ensures that users only see and interact with relevant controls for the current task, reducing perceived complexity while maintaining full functionality across all modes.

Inventive Principle:
Principle #15Dynamics

AI summary

An electronic communications method includes receiving, by a device, electronic information. The electronic communications method further includes receiving, by the device, additional electronic information. A time period between receiving the electronic information and the additional electronic information is less than another time period between receiving the electronic information and the additional electronic information by using a standard keyboard.
