Parcel Box with Pivoting Receiver for Secure Unattended Loading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parcel delivery boxes are not optimally designed for direct loading by delivery personnel and are not weather-resistant, leading to inefficiencies and potential package damage, especially in wet environments.
Innovation Solution
A parcel box with a pivotable receiving device that remains in a basic, accessible position for loading without requiring operation, allowing packages to be placed directly into the device and automatically slide into a collection container, featuring a design that prevents water accumulation and includes a lockable door for security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the receiving device is designed to be opened or activated before loading, then security and controlled access are improved, but ease of operation and loading speed deteriorate
Solution Approach 1:
The receiving device transitions from a static closed state to a dynamic open state during the tilting motion, automatically providing access for package insertion without requiring prior activation by the operator
Solution Approach 2:
The receiving device is pre-configured in an openable state that is triggered automatically by the tilting motion, so that the opening action is prepared in advance and executed automatically during normal operation
2Ease of operation
If the receiving device is opened during loading, then package insertion is enabled, but handling time increases and packages may fall out
Solution Approach 1:
The opening action and package insertion action are merged into a single continuous motion - the operator tilts the device open and inserts the package in one fluid motion, eliminating separate steps and reducing handling time
Solution Approach 2:
The receiving device maintains a continuous open state during the tilting and insertion process, allowing the package to be inserted without interruption or risk of falling out, as the opening remains sustained throughout the loading action
3Extent of automation
If the receiving device is tilted to enable package transfer, then automated package sliding into collection container is achieved, but device complexity increases
Solution Approach 1:
The tilting mechanism uses gravity as the driving force, creating a natural potential energy gradient that automatically slides packages from the receiving device into the collection container without requiring additional motors or actuators
Solution Approach 2:
The package transfer process is self-service - once the device is tilted, gravity automatically performs the work of sliding packages into the collection container without requiring external power or complex control systems
4Reliability
If the parcel box is designed for outdoor use, then weather resistance is improved, but package handling efficiency deteriorates due to wet and dirty environments
Solution Approach 1:
The receiving device dynamically transitions from a closed protected state to an open accessible state during loading, allowing efficient package insertion even in outdoor environments while maintaining weather protection when closed
Solution Approach 2:
The device provides localized protection - the collection container remains sealed and protected from weather, while the receiving device temporarily opens only at the front loading area to allow package insertion without exposing the entire system to environmental elements
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
Enables efficient and secure delivery and storage of packages without requiring operators to open the device, reducing handling time and preventing package damage, while maintaining weather resistance and secure access.
Implementation Method 1
By pivoting the receiving device, a passage into the collection container is enabled after a certain pivoting distance. Preferably, a picked-up package slides out of the receiving device into the collection container due to its own weight.

AI summary
A parcel box for receiving and storing parcels is disclosed. The parcel box is particularly suitable as a supplement to a mailbox. It comprises a swiveling receiving device with a shelf and a collection container. In a loading position, the receiving device can be directly loaded with a parcel. The receiving device can then be swivelled into a tilting position, in which the parcel slides out of the receiving device and into the collection container. The loading position is the receiving device's default, unattended position.
