Solution Overview
Problem
Existing security systems for homes and commercial properties face challenges with cabling difficulties, vulnerability to internet disruptions, and energy consumption, particularly in door lock systems that require continuous video streaming and rely on internet connectivity for remote monitoring.
Innovation Solution
An intelligent door lock system integrated with a plurality of cameras that communicate with each other and a lock device, allowing for remote monitoring and control via a mobile device, with a door status device coupled to the lock's drive shaft and powered by an energy source, enabling secure locking and unlocking, and featuring a wireless communication bridge for connectivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple cameras are connected via cabling to a security box for video transmission, then video capture and monitoring capability is improved, but installation difficulty and device complexity increase due to routing long cabling between dwelling and cameras
Solution Approach 1:
The patent extracts the video processing and storage functionality from a centralized security box and distributes it to individual wireless camera units. Each camera contains its own processor for video compression and storage memory, eliminating the need for long cabling connections to a central box while maintaining reliable video monitoring capability.
Solution Approach 2:
The patent introduces a wireless communication intermediary (wireless transceiver system) to replace physical cabling as the medium for video transmission. This allows cameras to communicate video data and control signals wirelessly with the dwelling, eliminating installation complexity associated with routing long cables through building structures.
2Ease of operation
If security systems rely on internet connectivity for remote monitoring and control, then remote access capability is improved, but system reliability deteriorates when internet connection is disrupted or cut
Solution Approach 1:
The patent implements local storage memory within each camera unit to buffer and store video data locally before transmission. This cushioning mechanism ensures that video monitoring and recording continue to function reliably even when internet connection is disrupted, as data is preserved locally and can be transmitted when connectivity is restored.
Solution Approach 2:
The patent enables cameras to autonomously manage their own video data storage and transmission without continuous reliance on external internet connectivity. Each camera unit independently handles video capture, compression, local storage, and wireless transmission, allowing the system to maintain core monitoring functions during internet outages.
3Adaptability or versatility
If cameras are connected to a central security box for coordinated operation, then system control capability is improved, but device complexity and vulnerability increase due to centralized architecture
Solution Approach 1:
The patent segments the centralized security system into distributed autonomous camera units, each with its own processor, memory, and wireless communication capabilities. This segmentation maintains coordinated control capability while reducing overall system complexity and eliminating the vulnerable centralized security box architecture.
Solution Approach 2:
The patent designs each camera unit to be a universal, multi-functional component that independently performs video capture, processing, storage, wireless communication, and control reception. This universality allows flexible system configuration and coordination without requiring a separate centralized control box, simplifying the overall architecture.
4Speed
If continuous video streaming is implemented for security monitoring, then real-time monitoring capability is improved, but energy consumption increases
Solution Approach 1:
The patent implements periodic or on-demand video transmission rather than continuous streaming. Cameras can capture and process video locally, then transmit data periodically or when triggered by specific events, maintaining real-time monitoring capability while significantly reducing continuous energy consumption compared to constant video streaming.
