Solution Overview

Problem

Many vehicles with factory-installed microphones are not compatible with aftermarket radios, requiring the installation of separate aftermarket microphones, which is cumbersome and often results in suboptimal placement.

Innovation Solution

A system and method to remotely flash a microphone module, allowing an original factory microphone to be compatible with an aftermarket radio by electronically transferring a computer program from a computer to the microphone module, which then calibrates the signal to be compatible with the aftermarket radio.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If an aftermarket microphone is installed to ensure compatibility with aftermarket radio, then compatibility is improved, but installation complexity and time increase

Engineering Contradiction:
ImprovecompatibilityVSAvoidinstallation complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

An adapter module is introduced as an intermediary component between the factory microphone and the aftermarket radio. This adapter contains a microprocessor that interfaces with both the factory microphone's protocol and the aftermarket radio's expectations, enabling compatibility without requiring complex installation procedures or modifications to existing microphone wiring.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If an aftermarket microphone is installed to ensure compatibility with aftermarket radio, then compatibility is improved, but installation time increases

Engineering Contradiction:
ImprovecompatibilityVSAvoidinstallation time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The adapter module is pre-configured with communication protocols and calibration data for multiple factory microphone types before installation. The microprocessor is pre-programmed with firmware that automatically identifies the connected microphone type and applies the appropriate communication protocol, eliminating the need for time-consuming manual configuration during installation.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If the original factory microphone is retained to save installation effort, then ease of installation is improved, but compatibility with aftermarket radio deteriorates

Engineering Contradiction:
Improveease of installationVSAvoidcompatibility
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The adapter module serves multiple functions: it acts as a protocol translator between different microphone types and the aftermarket radio, provides signal conditioning, enables remote microphone activation, and stores calibration data. This single universal adapter can work with various factory microphone types while maintaining full compatibility with the aftermarket radio system.

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

4Adaptability or versatility

If remote flashing capability is added to update microphone module firmware, then adaptability to new technologies is improved, but device complexity increases

Engineering Contradiction:
Improveadaptability to new technologiesVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Physical access to the microphone module for firmware updates is replaced with a wireless communication system. The adapter includes a communication interface that enables remote flashing of the microprocessor firmware through the vehicle's existing data bus or wireless connection, eliminating the need for physical disassembly or direct connection to update the module.

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

AI summary

A microphone module system comprising a microphone module with memory. The microphone module is connected to an original factory installed microphone of a vehicle and connected to an aftermarket radio to allow the original factory installed microphone to be compatible with an aftermarket radio. The microphone module includes a computer program that calibrates the factory installed microphone with the aftermarket radio that is originally embedded in the module memory. A method to remotely flash the module comprises steps of transferring a computer program to the microphone module, installing the microphone module in the vehicle, and calibrating the microphone module with the original factory microphone. The computer program may be specific to a make/model of a vehicle or universally applicable to all vehicles.
