Solution Overview
Problem
Existing electronic lockbox systems lack real-time data delivery and efficient matching of sales agents with prospects, as well as tracking of property visits, due to limitations in communication and data integration across the real estate industry.
Innovation Solution
An electronic lockbox system that includes a portable communications device with low power radio and wide area network capabilities, GPS, and a central computer database, enabling real-time data delivery, automatic matching of agents and prospects, and tracking of property visits through contextual data sharing and GPS location data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If real-time data delivery is implemented, then information relevance and transaction efficiency are improved, but system complexity and data integration requirements increase
Solution Approach 1:
A central clearinghouse computer is introduced as an intermediary to manage data delivery between the lockbox system and portable communication devices. The clearinghouse receives lockbox access data, queries the database for relevant property information, and delivers contextualized data to users in real-time, simplifying the overall system architecture while enabling comprehensive data delivery.
Solution Approach 2:
The system pre-loads and stores comprehensive property data, database records, and contextual information in advance in the central clearinghouse. When a lockbox is accessed, the system quickly retrieves and delivers relevant pre-prepared information rather than generating it on-demand, reducing real-time processing complexity.
2Measurement precision
If GPS location tracking is integrated, then agent-prospect matching accuracy is improved, but energy consumption and device complexity increase
Solution Approach 1:
The portable communication device activates GPS location tracking periodically or event-driven (when approaching a lockbox) rather than continuously. The motion sensor detects movement and triggers GPS updates only when needed, reducing energy consumption while maintaining sufficient location accuracy for matching agents with prospects.
Solution Approach 2:
The system automatically performs location-based agent-prospect matching without requiring manual intervention. The central clearinghouse receives location data, autonomously queries the database for matching prospects, and delivers matched information to the agent's device, reducing the energy and computational resources needed at the portable device.
3Loss of information
If comprehensive database integration is implemented, then data completeness and relevance are improved, but data processing time and system complexity increase
Solution Approach 1:
The central clearinghouse queries the database for specific types of information relevant to the current context (property details, comparable properties, agent-prospect matches) rather than retrieving all available data. This targeted approach ensures data completeness for the specific need while minimizing processing time and bandwidth usage.
Solution Approach 2:
The database is pre-organized and indexed with property data, agent profiles, prospect information, and contextual records in advance. When a query is initiated, the system quickly retrieves relevant pre-structured information rather than processing raw data, reducing data processing time while maintaining completeness.
4Adaptability or versatility
If multiple communication protocols are supported, then system versatility and adaptability are improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The lockbox system and portable communication devices are designed to support multiple communication protocols (low power radio, wide area network radio, GPS) within a single integrated platform. This universal design enables the system to adapt to different communication environments and device types without requiring separate specialized systems.
Data Source
AI summary
An electronic lockbox sends identifying data to a portable communications device, which relays that data to a central computer, generating a response from the central computer containing customized information of special interest to the user. Such data can include information relating to the lockbox's property, and contextually relevant information relating to other similar properties nearby. Such data from the central computer also can be delivered to one more auxiliary portable communication devices, including such devices carried by individuals either in close proximity to the lockbox or at a remote location. The data also could comprise visitation history relevant to the user, allowing an agent or a prospect to review information about previous visits to properties. The central computer can also query a user to provide location information for a lockbox that has been added to the system database.
