Solution Overview

Problem

Temporary access to restricted areas poses a risk of theft or compromise of personal belongings when service personnel enter without continuous monitoring, as existing systems lack automated and secure methods to ensure authorized access and activity recording.

Innovation Solution

Integration of body cameras with a locking mechanism, where the camera automatically records or streams data upon unlocking the door, using Bluetooth signal strength to determine proximity and trigger recording, and deactivates upon leaving, ensuring secure and monitored access without manual intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If body cameras are integrated with locking mechanisms to automatically record upon unlocking, then security monitoring and theft prevention are improved, but device complexity and energy consumption increase

Engineering Contradiction:

Improvesecurity monitoringVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the body camera, locking mechanism, proximity sensor, and communication module into an integrated system. The camera device is coupled with the locking mechanism such that they function as a unified security system, where the camera automatically activates when the lock detects proximity of an authorized device, eliminating the need for separate manual recording devices.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The body camera system serves multiple functions: it acts as both a security recording device and an access control system. The same device that unlocks the door also triggers the camera recording, and the system can transmit data both locally and remotely, providing versatile security capabilities without requiring additional specialized equipment.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Loss of information

If body cameras continuously record and transmit data, then real-time monitoring capability is improved, but battery consumption and energy usage increase

Engineering Contradiction:

Improvedata transmissionVSAvoidbattery consumption

Core Design Contradiction:

Loss of informationVSUse of energy by moving object

Solution Approach 1:

The camera operates in periodic intervals rather than continuously. It activates only when the proximity sensor detects an authorized device near the locking mechanism, records during the access event, and then deactivates. This on-demand operation significantly reduces energy consumption compared to continuous recording while ensuring data is captured during critical access moments.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The system automatically determines when recording is needed based on proximity detection, eliminating the need for manual activation. The camera self-regulates its operation based on the presence of authorized devices, turning itself on and off as needed, which optimizes energy usage without requiring external control.

Inventive Principle:

Principle #25Self-service

3Extent of automation

If proximity detection triggers automatic recording, then automated access monitoring is improved, but false activation risk and measurement precision requirements increase

Engineering Contradiction:

Improveautomatic recording triggerVSAvoidproximity detection accuracy

Core Design Contradiction:

Extent of automationVSMeasurement precision

Solution Approach 1:

The system uses feedback from the proximity sensor to control camera activation. The sensor continuously monitors for the presence of authorized devices and provides feedback signals to the camera control circuitry. When the sensor detects proximity within the threshold distance, it triggers the camera; when the device moves away, the camera deactivates, creating a closed-loop control system that reduces false activation.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The proximity sensor acts as an intermediary between the physical presence of an authorized device and the camera activation. Rather than directly detecting camera activation conditions, the system uses the sensor as an intermediate detection layer that translates physical proximity into electronic signals, providing a reliable buffer that reduces false positives while maintaining automated operation.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

Provided are techniques for integrating a body camera with a locking mechanism. The techniques include assigning a body camera to a user and detecting a proximity of the body camera to a locking mechanism. The techniques also include determining a state of the locking mechanism, and automatically triggering recording of the body camera based at least in part on the proximity and the state of the locking mechanism.
