Mailbox notification system and method of use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mailbox notification systems are inadequate for users who live far from their mailboxes, particularly in rural areas or without internet access, as they often rely on smartphone connectivity or short-range radio frequency, which may not be accessible or usable by all users.
Innovation Solution
A radio frequency transmitter attached to a mailbox that detects motion using a sensor and transmits a signal to a receiver, alerting the user via a radio frequency connection, without requiring cell service or internet, using wireless connectivity modules like XBee devices and a microcontroller to provide notifications across a range of up to two miles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If smartphone connectivity or internet service is required for mailbox notification, then notification functionality can be achieved, but accessibility is limited for elderly users or those without smartphones or internet access
Solution Approach 1:
The patent extracts the notification functionality from dependency on smartphones and internet services, creating a standalone system using a motion sensor attached to the mailbox and a separate receiver device that operates independently. This extraction eliminates the barrier of requiring smartphones or internet access while maintaining notification capability.
Solution Approach 2:
The patent introduces a motion sensor as an intermediary device attached to the mailbox that detects mailbox opening/closing actions and transmits signals to receiver devices. This intermediary enables notification functionality without requiring the user to have or use a smartphone, bridging the gap between the mailbox and various user devices including simple LED receivers.
2Ease of operation
If a flag or indicator is used to alert users of mail arrival, then notification is provided, but users living at a distance cannot see the flag or indicator
Solution Approach 1:
The patent replaces the mechanical flag system with an electronic motion sensor and wireless communication system. The motion sensor detects mailbox interactions and sends notifications electronically to receiver devices, eliminating the need for visual line-of-sight to a physical flag and enabling notification over distances of one mile or more.
3Device complexity
If short range radio frequency is used for notification, then device complexity is reduced, but the range and reliability of notification is limited
Solution Approach 1:
The patent creates a universal notification system where the motion sensor can communicate with multiple types of receiver devices using different communication methods. The system supports both simple LED receivers for short-range notifications and smartphone-compatible receivers for longer-range notifications, providing multi-functionality that adapts to various range requirements while maintaining system simplicity.
