Problem
Existing security systems for homes and commercial properties face challenges with cabling difficulties, vulnerability to internet disruptions, and unreliable data streaming, particularly in providing secure and programmatic delegated access to dwellings.
Innovation Solution
An intelligent door lock system that communicates with a server to grant third-party secured access programmatically, using a device coupled to a lock's drive shaft to sense movement and unlock/lock the door, and integrates with a wireless camera system for monitoring access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional cabled security systems are used, then video can be transmitted to the main system, but installation becomes difficult due to routing long cabling between cameras and the security box
Solution Approach 1:
The patent extracts the video processing functionality from the centralized security box and places it directly in the camera units. Each camera contains its own video compression processor, eliminating the need for long cabling to transmit raw video signals. Only control and power cables are needed, dramatically simplifying installation while maintaining video transmission capability.
Solution Approach 2:
The system divides the security functionality into independent camera units, each with its own processing capabilities. This segmentation allows each camera to operate autonomously with respect to video processing, removing the dependency on centralized processing and the associated cabling requirements.
2Quantity of substance
If multiple cameras are connected to a single security box, then video capture capacity increases, but each camera's frame rate decreases due to shared processing bandwidth
Solution Approach 1:
Each camera unit contains its own video compression processor, creating independent processing channels. This allows multiple cameras to operate simultaneously at full frame rates without sharing processing bandwidth, as each camera processes and compresses video locally before transmission.
Solution Approach 2:
The patent replaces the centralized mechanical processing system with distributed electronic processing in each camera unit. This substitution allows parallel processing of multiple video streams without the bandwidth constraints of a single centralized processor.
3Ease of operation
If the security box is located near a TV for remote viewing, then monitoring is enabled, but the system becomes vulnerable to internet disruptions and physical removal
Solution Approach 1:
The patent extracts the video processing and storage functionality from the vulnerable centralized security box and places it in distributed camera units. Each camera can independently store video locally and provide remote viewing, eliminating the single point of failure represented by the centralized box.
Solution Approach 2:
Each camera unit possesses local video processing and storage capabilities, making the system resilient to centralized failures. The local quality of each unit ensures continuous operation even if other parts of the system are disrupted or removed.
4Ease of manufacture
If wireless camera systems are used, then installation complexity decreases, but bandwidth collisions with other wireless systems cause unreliable video streaming
Solution Approach 1:
The patent replaces wireless video transmission with wired connections for the final video output, eliminating bandwidth collisions with other wireless systems. The wireless technology is retained for control and configuration, but critical video data uses reliable wired transmission.
