Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing trend of nuclear families and local crime prevention challenges, particularly in protecting children and elderly individuals, highlight the need for improved systems to enhance crime prevention measures.
Innovation Solution
A doorbell and intercom system integrated with a location notification system that uses identification signals and position information to generate target information about individuals, such as children and elderly persons, and alert protectors, while also generating suspicious person information based on camera data and alerting users through a guide route display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a doorbell system with camera and wireless communication is deployed, then crime prevention capability is improved, but device complexity and cost increase
Solution Approach 1:
The doorbell system integrates multiple functions including camera recording, wireless communication, image processing for suspicious person detection, and location notification into a single device. This multi-functionality approach allows the system to provide comprehensive crime prevention capabilities while avoiding the need for separate dedicated devices for each function, thereby managing complexity through integration rather than proliferation of components
Solution Approach 2:
The patent combines the doorbell unit with image processing capabilities, wireless communication modules, and integration with external devices into a unified system. By merging these previously separate functions into an integrated doorbell system, the patent achieves improved crime prevention capability while managing complexity through consolidated architecture
2Measurement precision
If real-time image processing and suspicious person detection are implemented, then security monitoring effectiveness is improved, but processing time and energy consumption increase
Solution Approach 1:
The doorbell system performs image processing and suspicious person detection in real-time as images are captured, rather than processing them afterward. This preliminary action approach ensures that detection occurs at the moment of capture, maintaining high detection accuracy while minimizing delays in identifying suspicious persons
Solution Approach 2:
The system rapidly processes images through automated analysis to quickly identify suspicious persons and transmit alerts. By rushing through the processing pipeline with optimized algorithms and immediate transmission to external devices, the system maintains high detection accuracy while minimizing the time loss associated with analysis
3Reliability
If location notification and tracking features are added, then protection of vulnerable individuals is improved, but system complexity and privacy concerns increase
Solution Approach 1:
The doorbell system integrates location notification and tracking functions alongside its primary doorbell and security features. This multi-functionality allows the same device to provide both traditional doorbell operations and advanced location-based protection for vulnerable individuals, improving reliability without requiring entirely separate systems
Solution Approach 2:
The system uses the doorbell unit as an intermediary device that captures images and retrieves location information, then transmits this data to external devices for processing and notification. This intermediary approach enables location tracking and protection capabilities while maintaining a relatively simple core doorbell system

AI summary
A doorbell system (1) includes a plurality of doorbells (2-1 to 2-n) each of which is attached to each residence and includes an operation unit (22) and a camera (26), and a control unit (4) capable of performing communication with the plurality of doorbells (2-1 to 2-n). The control unit (4) is configured to acquire position information of each of the plurality of doorbells (2-1 to 2-n) and an image captured by the camera (26), to generate target information about a target, based on the position information and the image, and to transmit the target information to an external device (3-1 to 30n) associated with a specific user.
