Problem
Traditional intercom systems are expensive, difficult to install, and lack versatility, often causing missed deliveries and unknown visitors, as they rely on physical installations and PSTN phones, which are becoming obsolete.
Innovation Solution
A smart intercom device using QR codes that connects visitors' smartphones to occupants within a building, allowing secure communication while maintaining privacy, with options for different contact methods and location-based access control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional intercom systems are used, then communication between visitors and occupants is enabled, but the system becomes expensive and difficult to install
Solution Approach 1:
The patent replaces traditional mechanical intercom systems with a smartphone-based application that uses QR codes for visitor registration and communication. The system substitutes physical intercom hardware with mobile device software, eliminating complex wiring and installation requirements while maintaining communication functionality between visitors and occupants.
Solution Approach 2:
The patent introduces a centralized server as an intermediary that manages visitor registrations, stores occupant information, and facilitates communication between visitors and occupants. This server-based approach replaces direct peer-to-peer intercom connections, simplifying the system architecture and reducing installation complexity while ensuring reliable communication.
2Reliability
If traditional intercom systems are used, then communication is possible, but the system lacks versatility and adaptability
Solution Approach 1:
The patent implements a dynamic system where the intercom functionality adapts to different users and scenarios through software configuration. The smartphone application can be customized for different occupants, buildings, and communication preferences, allowing the system to evolve and adapt to changing requirements without physical reconfiguration.
Solution Approach 2:
The patent creates a universal platform that can serve multiple functions beyond basic intercom communication, including visitor registration, package notification, two-way messaging, and integration with building access systems. The smartphone-based approach allows a single system to replace multiple specialized devices, enhancing versatility while reducing complexity.
3Ease of operation
If QR code scanning is implemented, then visitor registration and communication are simplified, but privacy concerns arise from data collection
Solution Approach 1:
The patent implements feedback mechanisms where occupants control what information is shared with visitors. The system provides occupants with notifications and choices about how to respond to visitor inquiries, allowing them to manage their privacy while enabling convenient communication. Visitor information is collected and stored securely, with occupants having control over data disclosure.
Data Source
AI summary
A smart intercom device is disclosed that utilizes scanning stickers and QR codes to communicate with others. Specifically, a visitor uses their smartphone to scan a scanning sticker or QR code at a building, apartment, home, office, etc. The QR code or scanning sticker connects the visitor with a specific person in the building, allowing the person to see who is at the door and communicate with them, as needed. Thus, instead of using a standard intercom system, visitors can scan the appropriate QR code and communicate with a person on the intercom list.
