School Security Drop Box with Integrated Communication and Sterilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security devices for public buildings lack efficient mechanisms for secure delivery and communication of objects to authorized recipients without compromising building security, particularly in scenarios where external individuals need to drop off items for internal recipients.
Innovation Solution
A drop box system positioned adjacent to a public building entrance, equipped with a communication unit that includes a video camera, call button, microphone, and speaker, allowing communication with an authorized representative within the building, along with an electronic lock and UV light emitter for sterilization, facilitating secure delivery and retrieval of objects while maintaining building security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a traditional locked door system is used for delivering objects to recipients inside public buildings, then building security is maintained, but efficient delivery and communication cannot be achieved
Solution Approach 1:
The patent introduces a drop box as an intermediary device between external deliverers and internal recipients. The drop box includes a communication unit with call button, speaker, and microphone that enables two-way communication without requiring physical access to the building. This resolves the contradiction by maintaining security (no door opening) while enabling efficient object delivery and communication.
Solution Approach 2:
The delivery system is segmented into separate functional components: the drop box for object transfer, the communication unit for interaction, and the surveillance station for monitoring. This segmentation allows each component to perform its function independently, improving overall delivery efficiency while maintaining security protocols.
2Illumination intensity
If the drop box is made transparent to allow visibility of objects, then object visibility is improved, but privacy and security are compromised
Solution Approach 1:
The drop box incorporates a movable partition that can dynamically adjust between transparent and opaque states. This dynamic feature allows the system to provide visibility when needed (for identifying objects) while maintaining privacy and security when required, resolving the contradiction between visibility and privacy protection.
3Reliability
If a surveillance system is added to monitor the drop box area, then security is enhanced, but device complexity increases
Solution Approach 1:
The surveillance camera is integrated with the existing communication unit housing, merging two security functions (communication and surveillance) into a single device. This reduces overall system complexity while enhancing security monitoring capabilities, as the camera shares the same mounting structure and power supply as the communication unit.

Function Achieved in This Case
Enables secure and efficient communication and delivery of objects to intended recipients within public buildings, enhancing security by allowing authorized personnel to manage drop-offs without compromising building access, while ensuring the cleanliness and safety of the drop box interior.
Implementation Method 1
a light emitter that emits electromagnetic radiation in the ultraviolet spectrum to sterilize an interior of the drop box

AI summary
A school security assembly for preserving security of a public building includes a drop box that is positionable adjacent to an entrance of a public building for receiving an object to be delivered to a recipient inside the public building. A communication unit is positioned adjacent to the drop box and the communication unit is in communication with the person when the person approaches the drop box. The communication unit is in communication with a surveillance station in the public building to facilitate the person to communicate with an authorized representative in the public building.
