Solution Overview

Problem

Current vehicle systems require manual control of various devices, leading to a challenge and distraction for drivers and passengers, necessitating a hands-free adjustment mechanism for in-vehicle elements.

Innovation Solution

A speech processing device that filters and processes data across an in-vehicle bus, using code phrases to selectively acquire and store user settings, enabling hands-free adjustment of vehicle systems through speech recognition and control, allowing for customization and operation of devices like mirrors, entertainment systems, and navigation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual control of vehicle devices is used, then device functionality is achieved, but driver distraction and operational challenge increase

Engineering Contradiction:
Improveease of operationVSAvoiddriver distraction
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent replaces manual mechanical control operations with speech-based acoustic control. The speech processing device captures voice commands, processes them through code phrase recognition, and translates them into control signals for vehicle devices, eliminating the need for manual manipulation of controls while driving.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The speech processing device acts as an intermediary between the driver and vehicle systems. It receives speech input, processes it through code phrase matching, retrieves appropriate control parameters from memory, and executes the corresponding device adjustments, serving as a mediator that reduces direct driver-device interaction.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If multiple vehicle devices are controlled manually, then full device functionality is available, but the complexity of control increases

Engineering Contradiction:
Improvedevice control capabilityVSAvoidcontrol complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The speech processing device provides a universal control interface for multiple vehicle devices including mirrors, seats, climate control, and entertainment systems. A single speech recognition system handles diverse control functions through code phrase interpretation, eliminating the need for separate controls for each device type.

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

Solution Approach 2:

The patent combines multiple control functions into a unified speech-based control system. Instead of separate manual controls for mirrors, seats, climate, and entertainment, all these functions are merged into a single speech processing interface that interprets code phrases and executes appropriate device adjustments.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of operation

If hands-free control is implemented through speech recognition, then driver distraction is reduced, but system complexity increases

Engineering Contradiction:
Improvehands-free operationVSAvoidsystem complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system performs preliminary actions by pre-defining code phrases and their corresponding control functions in memory before operation. When a driver speaks a code phrase, the system has already prepared the associated control parameters and device mappings, enabling rapid retrieval and execution without real-time complex processing.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The speech processing device creates a copy of the intended control action through code phrase recognition. Instead of directly interpreting complex natural language, the system matches speech against predefined code phrase templates, copying the essential control intent and executing the corresponding pre-programmed device adjustments.

Inventive Principle:
Principle #26Copying

AI summary

A speech processing device includes an automotive device that filters data that is sent and received across an in-vehicle bus. The device selectively acquires vehicle data related to a user settings or adjustments. An interface acquires the selected vehicle data from in-vehicle sensors in response to a user's articulation of a first code phrase. A memory stores the selected vehicle data with unique identifying data associated with the user and establishes a connection between the selected vehicle data and the user when a second code phrase is articulated. A data interface provides access to the selected vehicle data and stored relationship data and enables the processing of the data to customize the in-vehicle system. The data interface is responsive to the user's articulation of a third code phrase to process the selected vehicle data that enables the setting or adjustment of the in-vehicle system.
