Internet-Connected Key Box for Remote Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic key management systems require owners to be present for check-in and check-out processes, are insecure, and may not function without a Wi-Fi connection, posing challenges for remote access and key return, especially in multi-family properties.
Innovation Solution
An Internet-connected key box with a SIM card and wireless communication capabilities allows pre-approved visitors to access keys remotely by calling a unique phone number, eliminating the need for additional technology and enabling secure, remote management of key access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an analog key box is used, then key storage is provided, but the pass-code must be memorized and changed periodically, reducing security and convenience
Solution Approach 1:
The patent replaces the mechanical analog key box with an electronic key box system that uses electronic communication (SMS, email, push notifications) to control key access. The electronic system eliminates the need for physical pass-code memorization and manual changes, providing automated security management through digital means.
Solution Approach 2:
The electronic key box system enables automated key distribution and retrieval without requiring owner intervention. The system automatically sends access codes to authorized users, tracks key usage, and manages security protocols autonomously, freeing the owner from continuous manual security management.
2Ease of operation
If a digital door lock is installed, then remote access is enabled, but the door configurations must be permanently changed and visitors must install mobile applications, increasing complexity
Solution Approach 1:
The patent extracts the key storage function from the door structure itself, placing it in a separate electronic key box system. This allows the door to remain simple and unchanged while providing remote key access capabilities through the independent key box, eliminating the need to modify door configurations or require visitors to install applications.
Solution Approach 2:
The electronic key box serves multiple functions: storing keys, communicating with users via SMS/email/push notifications, tracking key usage, and providing automated access control. This multi-functional device replaces the need for complex door lock systems and mobile application installations, simplifying the overall system while maintaining remote access capabilities.
3Reliability
If the owner stays close to the property for check-in and check-out, then key access control is maintained, but the owner's time and mobility are restricted
Solution Approach 1:
The electronic key box system enables automated key distribution and retrieval operations without requiring owner presence. The system autonomously manages check-in and check-out processes by sending access codes to authorized users and tracking key usage, allowing the owner to be absent while maintaining secure key control.
Solution Approach 2:
The system provides automated feedback to the owner about key usage status, location, and retrieval events through SMS, email, or push notifications. This real-time information flow allows the owner to monitor key access control remotely without being physically present at the property.
4Ease of operation
If keys are placed in hidden locations, then access is provided when owner is absent, but security is compromised and key return cannot be ensured
Solution Approach 1:
The patent replaces the physical hidden key storage system with an electronic key box that uses digital communication and automated control mechanisms. This electronic system provides secure key access when the owner is absent while ensuring key return through automated tracking and controlled release mechanisms.
Solution Approach 2:
The electronic key box acts as an intermediary between the owner and the physical keys. It holds the keys securely and releases them only to authorized users under controlled conditions, eliminating the need for hidden key placements while ensuring both security and key return through automated protocols.

AI summary
A system for controlling key access using a phone and Internet-connected key box device. The key box device comprises a SIM card programmed with a unique phone number associated with the key box. Calling the phone number using any phone will provide access to the key box. A cloud computing software application then interfaces with operations programmed into a circuit board. A user then unlocks a key chamber by calling the number at a scheduled time. The key box device owner monitors and controls access to the box and its key chamber via the software application.
