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

VSEngineering 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

Engineering Contradiction:
Improvekey tracking accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

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

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

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

Inventive Principle:
Principle #25Self-service

2Reliability

If RFID tracking system is implemented, then key presence detection accuracy is improved, but system complexity and cost increase

Engineering Contradiction:
Improvekey presence detection reliabilityVSAvoidsystem structural complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

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

Inventive Principle:
Principle #1Segmentation

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

Inventive Principle:
Principle #24Intermediary (Mediator)

3Loss of time

If real-time key tracking is implemented, then key retrieval time is reduced, but energy consumption and system cost increase

Engineering Contradiction:
Improvekey retrieval timeVSAvoidsystem energy consumption
Core Design Contradiction:
Loss of timeVSUse of energy by moving object

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

Inventive Principle:
Principle #19Periodic action

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

Inventive Principle:
Principle #10Preliminary action
