Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security systems for homes and commercial properties face challenges with cabling difficulties, vulnerability to internet disruptions, and unreliable video 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 video monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional cabled security systems are used, then video can be transmitted to a central system, but installation becomes difficult and complex due to routing long cabling between cameras and the security box
Solution Approach 1:
The patent extracts the video processing capability from the central security box and places it directly in the camera units. Each camera now contains its own video compression processor, eliminating the need for complex cabling to transmit raw video signals. Only control signals and power need to be transmitted through cables, significantly reducing cabling complexity while maintaining video transmission reliability.
Solution Approach 2:
The patent segments the video processing function by distributing independent processing units within each camera rather than using a centralized processing system. This segmentation allows each camera to operate independently, reducing the complexity of the overall system cabling while maintaining reliable video transmission from each camera.
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 resources
Solution Approach 1:
The patent segments the video processing function by distributing independent processing units within each camera rather than using a centralized processing system. This allows each camera to process video independently at full frame rates (240 fps) while multiple cameras can be deployed in the system without frame rate degradation.
Solution Approach 2:
The patent implements video compression processing capability in each camera unit, creating copies of the processing functionality rather than using a single centralized processor. This allows multiple cameras to operate simultaneously at full frame rates without competing for shared processing resources.
3Ease of operation
If the security box is placed near a TV for remote viewing, then video monitoring is enabled, but the system becomes vulnerable to theft and damage of the security box which would remove all security data
Solution Approach 1:
The patent extracts the critical video processing and storage functionality from the vulnerable centralized security box and places it within the camera units themselves. Each camera maintains its own processed video data, so even if the security box is stolen or damaged, the security data remains protected in the distributed camera units.
Solution Approach 2:
The patent segments the security data storage by distributing it across multiple camera units rather than centralizing it in a single security box. This segmentation ensures that theft or damage to one location does not compromise the entire security system's data.
4Adaptability or versatility
If internet connectivity is used for remote access, then remote viewing is enabled, but the system becomes vulnerable to internet disruptions and cable cutting that prevent security notifications
Solution Approach 1:
The patent implements local video processing and storage capabilities within each camera unit as a preparatory measure against internet disruptions. By having processed video data and processing capability distributed locally in each camera, the system can continue to function and maintain security monitoring even when internet connectivity is interrupted or cables are cut.

Data Source
AI summary
A system allows dwelling access to third parties. An intelligent door lock system at the dwelling includes a device configured to be coupled to a drive shaft of a lock device, with the device sensing movement of the drive shaft to assist in locking and unlocking a lock of a lock device. The intelligent door lock system is configured to be in communication with a server. An occupant/or owner, or end-dwelling user of the dwelling communicates with the server to grant a third party secured access to a dwelling, which can by programmatic.
