Solution Overview

Problem

Misplacing personal mobile electronic devices, such as smartphones, often causes inconvenience and distress, and existing technologies do not effectively assist in locating them.

Innovation Solution

An ear-worn device equipped with a control circuit, microphone, electroacoustic transducer, motion sensor, and power supply circuit, capable of issuing a location command to a mobile device to trigger a locating signal, and providing guidance to the user through virtual 3-D audio or recorded sounds to help locate the device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional notification methods are used to locate mobile devices, then the device can be found when nearby, but the user experiences inconvenience and distress when the device is misplaced or lost

Engineering Contradiction:
Improvedevice location accuracyVSAvoiduser convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent introduces an intermediary device (such as a smartwatch or portable player) that acts as a mediator between the user and the misplaced mobile device. This intermediary can send commands to the mobile device and relay information back to the user, enabling location tracking and guidance even when the mobile device is not directly accessible or visible to the user

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If the mobile device emits a locating signal continuously, then the device can be located easily, but the energy consumption increases

Engineering Contradiction:
Improvedevice locatabilityVSAvoidbattery consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent implements periodic action by having the mobile device emit locating signals at intervals rather than continuously. The intermediary device can trigger these periodic signals on demand or at scheduled times, maintaining the ability to locate the device while significantly reducing overall energy consumption compared to continuous signal emission

Inventive Principle:
Principle #19Periodic action

3Ease of operation

If the ear-worn device provides detailed guidance including virtual 3-D audio and recorded sounds, then the user can locate the device more effectively, but the device complexity increases

Engineering Contradiction:
Improvedevice location guidanceVSAvoidsystem complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent merges multiple functions into the intermediary device, including playback of recorded sounds, generation of virtual 3-D audio cues, provision of turn-by-turn directions, and display of location information. By consolidating these diverse guidance mechanisms into a single wearable device, the system provides comprehensive location assistance without proportionally increasing overall system complexity

Inventive Principle:
Principle #5Merging (Combining)
