Parked Vehicle Camera Triggering by Vibration Detection

Solution Overview

Problem

Existing vehicle security systems fail to efficiently capture details of malicious events when the vehicle is powered off and parked, leading to inefficient use of memory space and potential loss of crucial evidence.

Innovation Solution

A vehicle security system that utilizes a microphone to detect vibrations caused by malicious events, activates only when necessary, and records video feeds of such events using a vehicle camera, applying filters to differentiate event types and store relevant data efficiently.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the vehicle camera continuously records video data when the vehicle is powered off, then the capture of malicious events is improved, but the memory space is wasted and energy is consumed unnecessarily

Engineering Contradiction:

Improvecapture of malicious eventsVSAvoidmemory space

Core Design Contradiction:

ReliabilityVSLoss of substance

Solution Approach 1:

The system performs preliminary action by detecting vibrations caused by malicious events before triggering video recording. The microphone continuously monitors for abnormal vibrations and only activates the camera when suspicious activity is detected, preventing unnecessary recording while ensuring malicious events are captured

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system replaces continuous mechanical/video recording with acoustic vibration detection. Instead of continuously operating the camera mechanism, the system uses the microphone to detect vibrations caused by malicious events, triggering video recording only when necessary

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If the vehicle camera continuously records video data when the vehicle is powered off, then the capture of malicious events is improved, but the energy consumption increases unnecessarily

Engineering Contradiction:

Improvecapture of malicious eventsVSAvoidenergy consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system performs preliminary action by detecting vibrations caused by malicious events before triggering video recording. The microphone continuously monitors for abnormal vibrations and only activates the camera when suspicious activity is detected, preventing unnecessary recording while ensuring malicious events are captured

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system uses periodic action by having the microphone continuously monitor for vibrations and triggering video recording only during periods when malicious events are detected. This intermittent operation based on detected events significantly reduces energy consumption compared to continuous recording

Inventive Principle:

Principle #19Periodic action

3Loss of information

If the vehicle camera records all events, then the identification of perpetrators is improved, but the memory space is wasted on unnecessary data

Engineering Contradiction:

Improveidentification of perpetratorsVSAvoidmemory space

Core Design Contradiction:

Loss of informationVSLoss of substance

Solution Approach 1:

The system performs preliminary action by detecting vibrations caused by malicious events before triggering video recording. The microphone continuously monitors for abnormal vibrations and only activates the camera when suspicious activity is detected, preventing unnecessary recording while ensuring malicious events are captured

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system extracts only the necessary video data related to malicious events from the continuous video stream. By using vibration detection as a trigger, the system extracts and stores only the portions of video that contain relevant information about perpetrators, discarding unnecessary footage

Inventive Principle:

Principle #2Taking out (Extraction)
