Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing virtual intercom systems are cumbersome, often requiring visitor credentials, location computations, and detector presence, limiting their application beyond traditional buildings.
Innovation Solution
A system that enables communication between an occupant and a visitor using smartphone technology, eliminating the need for visitor credentials, location computations, and detectors, and allowing access to any property protected by a smart lock.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If visitor credentials and location computations are required, then security and identification reliability are improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The patent extracts the identification function from complex credential verification systems and location computation systems, using only the smartphone's existing identifier and communication capabilities. This removes unnecessary complexity while maintaining reliable identification of the visitor through the smartphone device itself.
Solution Approach 2:
The system uses the visitor's smartphone as a multi-functional device that serves as both identification credential and communication endpoint. The smartphone's existing capabilities (identifier, camera, communication interfaces) are leveraged universally without requiring specialized visitor credentials or separate detection systems.
2Measurement precision
If detectors and location computations are added, then visitor detection precision is improved, but device complexity and ease of operation worsen
Solution Approach 1:
The visitor's smartphone performs self-service functions by automatically providing its identifier and establishing communication channels without requiring external detectors or location computations. The device itself serves as the detection and identification mechanism, simplifying operation while maintaining precision through the smartphone's inherent capabilities.
3Reliability
If hard-wired intercom systems are used, then communication reliability is improved, but adaptability to different property types deteriorates
Solution Approach 1:
The patent replaces hard-wired mechanical intercom systems with wireless smartphone-based communication. This substitution maintains communication reliability through established smartphone communication protocols while dramatically improving adaptability to various property types (buildings, vehicles, personal property) without requiring physical installation infrastructure.
Solution Approach 2:
The smartphone-based system provides universal communication capability across diverse property types using the same technology platform. The system adapts to buildings, vehicles, cargo containers, and personal property without requiring different hardware systems, maintaining reliability through the smartphone's consistent communication capabilities.
4Reliability
If visitor profile creation and credential verification are required, then security reliability is improved, but ease of manufacture and deployment worsen
Solution Approach 1:
The system extracts the security verification function from complex profile creation and credential management systems, relying instead on the smartphone's inherent identifier and the occupant's discretion to grant access. This removes the need for elaborate credential verification infrastructure while maintaining security through the occupant's control.

AI summary
A method for facilitating communication between a first person such as an occupant of a building with a smart lock and a second person such as a visitor includes receiving at a computer system, from a visitor device app, a smart lock identifier and a visitor device app identifier so the occupant can establish a communication channel between the occupant and the visitor and if desired allow the visitor access to the building (or other property).
