Doorstep Package Sensor with Wireless Notification and Alarm
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Packages delivered to doorsteps are vulnerable to theft, and existing notification systems are not reliable, often failing to inform recipients of delivery or unauthorized removals.
Innovation Solution
A package delivery notification and protection system that includes a sensor to detect package placement or removal, wireless communication for notifications, and an alarm for unauthorized removal, integrated with a camera for recording video or images upon motion detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If packages are left on the doorstep for delivery, then delivery convenience is improved, but package security deteriorates due to theft vulnerability
Solution Approach 1:
The system performs preliminary actions by detecting package placement before the recipient arrives, sending notifications in advance, and preparing security responses. The sensor detects package placement on the doorstep, triggers immediate notifications to the recipient's device, and prepares alarm systems before the recipient returns home, allowing proactive rather than reactive security measures.
2Device complexity
If notification systems are simplified, then device complexity is reduced, but notification reliability deteriorates
Solution Approach 1:
The system implements feedback mechanisms where the sensor continuously monitors the doorstep, detects package placement, and triggers notifications. The recipient's device provides feedback by receiving and acknowledging notifications, and the system can send follow-up alerts if package removal is detected without proper authorization, creating a closed-loop verification system that enhances reliability.
Solution Approach 2:
The patent introduces an intermediary notification device that acts as a mediator between the package delivery event and the recipient. This intermediate device receives sensor signals, processes them through wireless communication, and delivers notifications to the recipient's electronic device, adding a layer of reliable communication without significantly increasing overall system complexity.
3Object-affected harmful factors
If security monitoring is continuous, then package protection is improved, but energy consumption increases
Solution Approach 1:
The system employs periodic action by using motion-activated sensors and alarm systems that remain in standby mode and only activate when motion or package placement is detected. The sensor periodically checks for package presence, and the alarm system activates only when unauthorized removal is detected, providing continuous protection coverage while consuming minimal energy during idle periods.

AI summary
A package delivery notification and protection device includes a package sensor including a placement surface. The package sensor is configured to generate a sensor signal indicating whether a package has been placed on or removed from the placement surface. Wireless communications circuitry is configured to communicate over a wireless network and processing circuitry is coupled to the package sensor and to the wireless communications circuitry to communicate over the wireless network. The processing circuitry is configured to send a delivery notification over the wireless network responsive to the sensor signal indicating a package has been placed on the placement surface. The package delivery notification and protection device may include and alarm that the processing circuitry activates upon unauthorized removal of a delivered package from the placement surface.
