Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current solutions for preventing text messaging while driving are flawed, as they cannot accurately determine whether the user is the driver or a passenger, and do not allow safe communication via SMS in attention-intensive situations.

Innovation Solution

A method and system for converting text messages to speech data, allowing recipients to receive messages in a voice format upon request, which can be initiated through buttons, voice commands, or gestures, enabling safe SMS communication without requiring users to manually type messages.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If text messaging is used while driving, then communication functionality is maintained, but safety deteriorates due to distraction and manual operation

Engineering Contradiction:

Improvetext messaging operationVSAvoiddriving safety

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent replaces manual text input operations with voice-based communication. The voice mail system allows drivers to send and receive messages through speech rather than manual typing, eliminating the need to interact with the mobile device keyboard while driving.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces voice mail as an intermediary system between the driver and the mobile device. Instead of directly interacting with the text messaging interface, drivers communicate through voice mail messages, which are then delivered to recipients, providing a safe indirect communication method.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If GPS speed detection is used to block text messaging, then driving safety may be improved, but accuracy deteriorates because it cannot distinguish between drivers and passengers

Engineering Contradiction:

Improvetext messaging safetyVSAvoiddriver detection accuracy

Core Design Contradiction:

Object-affected harmful factorsVSMeasurement precision

Solution Approach 1:

Instead of trying to detect whether the user is driving (which is difficult and inaccurate), the system inverts the approach by providing a communication method that is safe for drivers to use regardless of detection status. Voice mail allows drivers to communicate safely without needing accurate driver detection.

Inventive Principle:

Principle #13The other way round (Inversion)

3Loss of information

If manual text typing is required, then message accuracy is maintained, but ease of operation deteriorates for elderly or handicapped users

Engineering Contradiction:

Improvemessage accuracyVSAvoidtext input accessibility

Core Design Contradiction:

Loss of informationVSEase of operation

Solution Approach 1:

The patent replaces manual text input with voice-based communication. Users can dictate messages using speech rather than manually typing, making communication accessible to elderly or handicapped individuals who may have difficulty with manual dexterity required for text input.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

Systems, methods, and computer-readable storage devices for converting text messages to speech data. A text message may be received. The text message may be associated with a recipient identification of a recipient of the text message. Preference information for converting the text message to speech data may be received. The text message may be converted to the speech data based on the preference information. The speed data may be communicated to the recipient.
