Solution Overview
Problem
Existing home and facility security systems face challenges with high installation and maintenance costs due to physical wiring, reliability issues with self-powered wireless devices, increased power requirements for advanced monitoring capabilities, and privacy concerns from constant camera recording, along with complex installation procedures and regulatory compliance.
Innovation Solution
An integrated security arrangement that includes intrusion sensors, motion sensors, and image-capture devices, with a mapping database to associate sensors with cameras, enabling cameras only upon intrusion detection, reducing power consumption through optimized frequency and communication interval usage, and implementing bi-directional communication to minimize power usage and maintain privacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If wireless monitoring devices are used to eliminate physical wiring, then installation complexity and cost are reduced, but power consumption increases and battery life is limited
Solution Approach 1:
The patent implements periodic communication intervals where monitoring devices transmit data at scheduled times rather than continuously. The controller receives data packets at specific intervals and the system manages communication timing periodically, reducing overall power consumption while maintaining monitoring effectiveness
Solution Approach 2:
The patent adjusts communication parameters dynamically, including transmission power levels, data packet sizes, and communication frequency. By optimizing these parameters based on system needs and environmental conditions, the device achieves lower power consumption while maintaining reliable wireless communication
2Reliability
If image-capture devices are continuously enabled for monitoring, then security coverage is improved, but privacy invasion increases and power consumption rises
Solution Approach 1:
The patent implements periodic activation of image-capture devices based on intrusion detection events. Rather than continuous recording, cameras are enabled only when motion sensors or intrusion sensors detect suspicious activity, creating a periodic monitoring pattern that balances security needs with privacy protection
Solution Approach 2:
The system uses motion sensors and intrusion sensors to detect potential threats before activating image-capture devices. This preliminary detection mechanism allows the system to prepare for monitoring only when necessary, reducing unnecessary privacy invasion while maintaining security coverage
3Reliability
If transmission power is increased to reduce interference, then communication reliability is improved, but power consumption increases
Solution Approach 1:
The patent dynamically adjusts transmission power levels based on communication quality requirements. When interference is detected or communication reliability deteriorates, the system increases power temporarily; when conditions are good, it reduces power to minimize consumption, optimizing the balance between reliability and energy use
4Adaptability or versatility
If advanced monitoring capabilities are added to devices, then functionality is improved, but device size and power requirements increase
Solution Approach 1:
The patent divides the monitoring system into separate functional modules: motion sensors, intrusion sensors, image-capture devices, and a central controller. This segmentation allows each component to be optimized independently, enabling advanced monitoring capabilities while keeping individual device sizes manageable through specialized rather than all-in-one design
