Solution Overview

Problem

Existing ear set devices for vehicles lack the ability to effectively communicate and respond to vehicle operations and passenger events, such as calls, messages, navigation information, and emergency situations, while also failing to provide clear audio signals amidst noise and prioritize alerts based on user presence and location.

Innovation Solution

An ear set device with a main body and earphones that include a communication unit for wireless communication, a control unit to process and output vehicle-related information, and a microphone to detect external signals, enabling the device to determine user presence, vehicle operations, and external events, and adjust audio output accordingly to prioritize important information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If the ear set device outputs all vehicle operation information and external events through audio, then the user receives comprehensive information, but the audio output becomes cluttered and critical alerts are not prioritized

Engineering Contradiction:
Improveinformation delivery completenessVSAvoidaudio clutter and noise
Core Design Contradiction:
Loss of informationVSObject-generated harmful factors

Solution Approach 1:

The patent applies local quality by differentiating the treatment of different information types based on their importance. Critical alerts (emergency braking, collision warnings) receive prioritized audio output with higher volume and immediate notification, while non-critical information (routine vehicle status, non-urgent messages) is either suppressed or delivered with lower priority. This selective quality assignment resolves the contradiction by ensuring comprehensive information delivery for critical events while filtering out clutter from non-critical events.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The control unit serves as an intermediary that filters and prioritizes information before audio output. It receives multiple information streams from vehicle sensors and external sources, evaluates their importance levels, and selectively routes them to the audio output system. This intermediary function prevents audio clutter by blocking non-critical information while ensuring critical alerts are delivered clearly and promptly.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of information

If the ear set device provides audio feedback for all events including calls and messages, then the user remains informed of all communications, but the audio output interferes with the user's ability to hear external sounds

Engineering Contradiction:
Improvecommunication information deliveryVSAvoidreduced external sound perception
Core Design Contradiction:
Loss of informationVSObject-affected harmful factors

Solution Approach 1:

The patent applies partial action by selectively providing audio feedback only for certain types of events rather than all events. Critical safety-related communications (emergency calls, urgent messages from specified contacts) receive audio feedback, while non-critical communications are suppressed or delivered through alternative means. This partial approach ensures communication information is delivered when necessary without continuously interfering with external sound perception.

Inventive Principle:
Principle #16Partial or excessive action

Solution Approach 2:

Different quality levels of audio feedback are assigned to different communication types based on their urgency and importance. Critical communications receive high-priority audio output with immediate notification, while non-critical communications are either silenced or delivered with lower priority. This quality differentiation resolves the contradiction by maintaining external sound awareness while ensuring critical communication information is delivered.

Inventive Principle:
Principle #3Local quality

3Ease of operation

If the ear set device outputs navigation information continuously, then the user has constant route guidance, but the audio output creates noise and distracts the driver

Engineering Contradiction:
Improvenavigation guidance availabilityVSAvoiddriver distraction and noise
Core Design Contradiction:
Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The patent applies periodic action by providing navigation information at specific intervals and only when relevant, rather than continuous output. Turn-by-turn directions are delivered at appropriate moments before maneuvers are required, and route confirmation is provided at key decision points. This periodic delivery maintains ease of operation by providing necessary guidance while minimizing distraction and noise from constant audio output.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

Different quality levels of navigation information are provided based on the driving context and urgency. Critical navigation alerts (upcoming turns, route deviations) receive prominent audio output, while routine status information is delivered with lower priority or suppressed. This quality-based approach ensures navigation guidance is available when needed without creating unnecessary distraction or noise.

Inventive Principle:
Principle #3Local quality

4Loss of information

If the ear set device monitors all external audio signals including alarms and emergency sounds, then the user is aware of external events, but the device complexity increases

Engineering Contradiction:
Improveexternal event awarenessVSAvoidsignal processing complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent applies extraction by selectively extracting and processing only specific types of external audio signals that are relevant to safety and operation, rather than analyzing all external sounds. The system focuses on identifying critical patterns such as emergency vehicle sirens, collision sounds, and other safety-relevant acoustic events. This selective extraction maintains external event awareness while reducing device complexity by avoiding comprehensive analysis of all audio inputs.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The control unit acts as an intermediary that receives raw external audio signals, filters them through pattern recognition algorithms, and selectively processes only those signals indicating significant events. This intermediary processing layer reduces complexity by preventing detailed analysis of all audio inputs, focusing only on safety-critical patterns while maintaining awareness of important external events.

Inventive Principle:
Principle #24Intermediary (Mediator)
