Solution Overview
Problem
Existing motor vehicle interior monitoring systems consume excessive electrical energy and generate false alarms due to continuous operation, particularly in electric vehicles, reducing their range and reliability.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the optical detection device is activated continuously to monitor the interior, then monitoring reliability is improved, but electrical energy consumption increases
Solution Approach 1:
The optical detection device is activated periodically only when motion is detected by the motion detection device, rather than operating continuously. This periodic activation based on motion events reduces electrical energy consumption while maintaining monitoring reliability for relevant incidents.
Solution Approach 2:
A motion detection device serves as an intermediary between the continuous monitoring need and the optical detection device. The motion detection device triggers the optical detection device only when movement is detected, acting as a mediator that reduces energy consumption while maintaining monitoring effectiveness.
2Measurement precision
If the optical detection device operates continuously to detect all events, then detection completeness is improved, but false alarms increase
Solution Approach 1:
The motion detection device acts as an intermediary filter that distinguishes between relevant motion events and irrelevant disturbances. By triggering the optical detection device only on motion events, the system achieves detection completeness for relevant events while minimizing false alarms from non-motion disturbances.
Solution Approach 2:
The monitoring system applies different detection qualities to different types of events. Motion-based triggering provides high sensitivity for relevant events, while the system can suppress or adjust response to non-motion disturbances, creating local quality differentiation in detection sensitivity.
3Speed
If the optical detection device is activated continuously, then real-time monitoring capability is improved, but energy consumption increases
Solution Approach 1:
The system maintains real-time monitoring capability by immediately activating the optical detection device when motion is detected, while using periodic motion-based triggering instead of continuous operation to reduce energy consumption.
Solution Approach 2:
The motion detection device performs preliminary detection of motion events before activating the higher-power optical detection device. This preliminary action enables rapid response to relevant events while avoiding continuous high-energy operation.
