Drop box item deposit sensor system and methods of using the same
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional drop boxes require substantial time and effort for personnel to determine if items have been deposited, as retrieving items is a manual and time-consuming process, and there is a need for mechanisms to monitor usage without significant time investments.
Innovation Solution
Integration of sensor systems with drop boxes that include tray movement sensors, item detection sensors, and an onboard controller to monitor and transmit status data, allowing for automated detection and notification of items deposited, reducing manual checks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual checking of drop box contents is performed, then personnel can determine if items have been deposited, but substantial time and effort are required
Solution Approach 1:
The patent replaces the manual mechanical checking process with an automated sensor system comprising optical sensors, weight sensors, and tray position sensors that automatically detect item deposition without requiring personnel to physically open or inspect the drop box
Solution Approach 2:
The drop box system performs self-monitoring through integrated sensors that automatically detect when items are deposited and generate notifications, eliminating the need for external personnel to manually check contents
2Measurement precision
If sensor systems are continuously activated to monitor drop box contents, then item deposition can be accurately detected, but power consumption increases
Solution Approach 1:
The sensor system operates in periodic cycles, activating sensors only during expected deposition periods or when triggered by motion detection, rather than continuous operation, thereby reducing overall power consumption while maintaining detection capability
Solution Approach 2:
The system uses preliminary motion sensors and tray position sensors to detect approaching items or tray opening events, which then trigger the activation of primary item detection sensors only when needed, avoiding continuous operation
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 sensor system enables efficient monitoring of drop box contents, minimizing time spent by personnel and optimizing collection processes by automatically detecting items and sending alerts for retrieval.
Implementation Method 1
an infrared or other optical sensor system (e.g., light curtain sensor, time-of-flight sensor, and/or the like) configured to detect items sliding off of the tray and into the interior of the drop box
Implementation Method 2
the one or more tray movement sensors may comprise an accelerometer configured to detect an angle of rotation of the movable deposit tray
Data Source
AI summary
An item drop box sensor system for detecting items deposited within a drop box may be configured to detect movement of an item deposit tray and to detect items deposited within the drop box. The drop box sensor system may comprise one or more tray movement sensors for detecting movement of the deposit tray, one or more item detection sensors configured to detect items passing into the drop box via the deposit tray, and an onboard controller for selectively activating the various sensors to conserve power and for transmitting data indicative of the status of the drop box to a central server configured for scheduling item pickups for various geographically spaced drop boxes.
