Solution Overview

Problem

Existing communication systems for wearable cameras and in-vehicle devices lack efficient methods to establish and maintain wireless communication settings when police officers switch vehicles, leading to hindered operations due to potential misalignment of communication links.

Innovation Solution

A wearable camera system that includes a first communication setter for setting up wireless communication with an in-vehicle device, a memory for storing communication setting information, and a controller that deletes this information after a certain time, ensuring periodic re-establishment of communication links when switching vehicles.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If communication setting information is stored in the wearable camera to maintain wireless communication with an in-vehicle device, then communication reliability is improved, but when the user switches vehicles, the stored information causes connection errors and operation hindrance

Engineering Contradiction:

Improvecommunication reliabilityVSAvoidoperation smoothness when switching vehicles

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system performs preliminary detection of communication setting information before actual communication occurs. The wearable camera checks whether stored communication settings match the current in-vehicle device, and if not, it proactively notifies the user to delete or update the settings, preventing connection errors before they occur.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system implements a feedback mechanism where the wearable camera detects the presence of communication setting information, compares it with the current vehicle's device information, and provides feedback to the user through notifications. This feedback loop enables the user to understand the connection status and take appropriate actions.

Inventive Principle:

Principle #23Feedback

2Duration of action of stationary object

If the wearable camera continuously stores communication setting information, then wireless communication can be maintained, but the user cannot easily check or verify the communication status when switching vehicles

Engineering Contradiction:

Improvecommunication setting retention timeVSAvoidcommunication status verification difficulty

Core Design Contradiction:

Duration of action of stationary objectVSDifficulty of detecting and measuring

Solution Approach 1:

The system provides visual feedback through LED indicators that display the communication setting status. Different LED patterns indicate whether communication settings are stored, whether they match the current vehicle, or whether user action is required, making the communication status easily detectable without complex interfaces.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system uses color-changing LED indicators to communicate device states. For example, different colors or blinking patterns indicate whether communication settings are properly configured or need user intervention, providing intuitive visual information about the communication status.

Inventive Principle:

Principle #32Color changes

3Speed

If the wearable camera automatically connects to the last used vehicle, then connection speed is improved, but it may connect to the wrong vehicle when multiple vehicles are available

Engineering Contradiction:

Improveconnection establishment speedVSAvoidconnection accuracy to correct vehicle

Core Design Contradiction:

SpeedVSReliability

Solution Approach 1:

Before establishing automatic connection, the system performs a preliminary check to detect whether communication setting information already exists in the wearable camera. This preliminary detection prevents erroneous connections by identifying potential mismatches between stored settings and the current target vehicle.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system takes preliminary anti-action by detecting potential connection errors before they occur. When the detected vehicle information does not match the stored communication settings, the system prevents the erroneous connection by notifying the user and requiring manual intervention.

Inventive Principle:

Principle #9Preliminary anti-action

AI summary

A wearable camera includes an image capture device, a processor, and first and second memories. The image capture device images a subject. The first memory at least temporarily stores first communication setting information for communication with an in-vehicle communication device. The second memory stores a program that, when executed by the processor, causes the wearable camera to: perform a communication setting process that establishes a communication connection between the wearable camera and the in-vehicle communication device, delete the first communication setting information from the first memory after a lapse of a certain time from a timer reset, the timer reset occurring in response to establishment of the communication connection between the wearable camera and the in-vehicle communication device, and notify that the first communication setting information is not stored in the first memory, in response to determining that the first communication setting information is not stored in the first memory.
