Solution Overview
Problem
Current key management systems in the real estate industry are prone to errors and key misplacement, making it difficult to track and retrieve missing keys, which often goes unnoticed until they are urgently needed.
Innovation Solution
A key management system utilizing RFID technology with key storage positions, a graphical user interface for loaning keys, and visual indicators to track key presence and status, along with notifications and reports to prevent and address missing keys, includes a dashboard for overview and trend analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual key tracking using books or spreadsheets is used, then the system is simple to operate, but keys are easily lost and tracking accuracy deteriorates
Solution Approach 1:
The patent replaces manual mechanical tracking systems (books, spreadsheets) with an automated electronic system using RFID readers, processors, and databases to detect key presence/absence and automatically update records, eliminating manual data entry errors and improving tracking accuracy
Solution Approach 2:
The system enables self-service key management where the RFID detection system automatically identifies keys, updates their status, and notifies relevant parties without requiring manual intervention, allowing the system to manage itself
2Reliability
If RFID tracking system is implemented, then key presence detection accuracy is improved, but system complexity and cost increase
Solution Approach 1:
The patent divides the key management system into independent modular components: RFID readers at storage positions, central processing unit, database system, and notification system. Each module performs a specific function and can be independently configured or replaced, reducing overall system complexity while maintaining high reliability
Solution Approach 2:
The patent introduces a central processing unit as an intermediary that coordinates between RFID readers, database, and notification systems. This mediator simplifies the architecture by centralizing logic and providing a single point of control, making the system more manageable despite its complexity
3Loss of time
If real-time key tracking is implemented, then key retrieval time is reduced, but energy consumption and system cost increase
Solution Approach 1:
The patent implements periodic RFID scanning at key storage positions rather than continuous monitoring. The system checks for key presence/absence at regular intervals or triggered by door openings/closings, reducing energy consumption while still providing timely key tracking and retrieval capability
Solution Approach 2:
The system performs preliminary key tracking and status updates automatically as keys are stored or retrieved, so that key location information is already available when needed. This eliminates the need for real-time continuous tracking while ensuring quick key retrieval when required
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system enables efficient and accurate key management, reducing the number of missing keys by providing real-time tracking and alerts, ensuring timely retrieval and minimizing costs associated with lost keys.
Implementation Method 1
determine, using the RFID reader, the presence or absence of the keys in the storage positions
