Parcel storage assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing storage devices fail to securely deliver parcels to authorized recipients and notify them of the delivery, as they lack mechanisms to prevent unauthorized access and provide alerts upon parcel deposition.
Innovation Solution
A storage device with upper and lower doors, pivotally integrated trays, and an alert unit that detects parcel deposition and broadcasts a signal to a personal electronic device, ensuring secure storage and notification of delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple drop box with hinged trap door is used, then the device complexity is reduced, but the delivery security and recipient notification capability deteriorate
Solution Approach 1:
The device is divided into multiple functional segments: upper door assembly for parcel input, lower door assembly with lock mechanism for secure storage, pivotally integrated trays for parcel transfer, and alert unit with communication module for notification. Each segment performs a specific function, resolving the contradiction by organizing complexity into manageable, purpose-driven modules that collectively enhance delivery security.
Solution Approach 2:
The alert unit is pre-configured with communication capabilities and is positioned to detect parcel deposition before the lower door is opened. The system performs preliminary notification to the recipient's personal electronic device, ensuring secure delivery confirmation before actual parcel retrieval, thus enhancing delivery security without requiring complex real-time monitoring.
2Ease of manufacture
If traditional mail slot with trap door is used, then the ease of manufacture is improved, but the parcel security against unauthorized access deteriorates
Solution Approach 1:
The trays are pivotally integrated into the box, allowing them to dynamically transition between stored and deployed positions. When the upper door opens, the trays automatically pivot to a deployed position to receive and transfer parcels. This dynamic mechanism provides active security control while maintaining manufacturing simplicity through standardized pivot connections.
Solution Approach 2:
The lock mechanism on the lower door assembly acts as an intermediary between the parcel storage space and unauthorized access. It provides a controlled interface that requires authentication (key, code, or biometric) before allowing door opening, effectively blocking unauthorized access while maintaining ease of manufacture through conventional locking components.
3Device complexity
If no alert mechanism is included, then the device complexity is reduced, but the recipient notification capability deteriorates
Solution Approach 1:
The alert unit provides immediate feedback to the recipient's personal electronic device when a parcel is deposited into the box. The communication module transmits a notification signal containing delivery information, creating a closed-loop feedback system that confirms successful delivery without requiring the recipient to physically check the box, thus preventing information loss about parcel arrival.
Solution Approach 2:
The mechanical notification system is replaced with an electronic alert unit that uses electromagnetic communication signals to notify the recipient. Instead of mechanical indicators like bells or flags, the system uses wireless or wired electronic communication to transmit delivery information to the recipient's personal electronic device, reducing physical complexity while enhancing notification capability.

AI summary
A parcel storage assembly includes a box that has an upper door and a lower door. A first tray and a second tray is each pivotally integrated into the box. The first tray and the second tray are positioned in a deployed position for having the parcel positioned thereon when the upper door is opened. The first tray and the second tray are each positioned in a stored position when the upper door is closed in order to drop the parcel downwardly in the box. An alert unit is integrated into the box and the alert unit detects when the parcel falls into the box. The alert unit broadcasts an alert signal to the personal electronic device when the alert unit detects the parcel to alert the authorized recipient that the parcel has been deposited into the box.
