Rotating Parcel Receptacle With Drum Access Restriction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing delivery receptacles lack effective mechanisms to restrict unauthorized access to deposited parcels after they are placed inside, which can lead to theft or vandalism.
Innovation Solution
A delivery receptacle design featuring a rotatable drum mechanism within a housing, where the drum rotates between loading and unloading positions, and a linking mechanism between the delivery door and drum ensures secure access restriction, with additional features like a locking device and secure storage compartment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a simple open receptacle is used, then ease of access is improved, but security against unauthorized access deteriorates
Solution Approach 1:
The receptacle is segmented into multiple functional components: an input opening for public access, a drum mechanism for parcel deposition, and a separate secure storage compartment for protected access. This segmentation allows different access levels for different purposes, enabling easy public input while maintaining security for stored items.
Solution Approach 2:
The drum mechanism serves as an intermediary between the public input opening and the secure storage compartment. It receives parcels from the public and transfers them to secure storage, acting as a mediator that prevents direct access to stored items while maintaining ease of public deposition.
2Object-affected harmful factors
If a secure locking mechanism is added, then security is improved, but device complexity worsens
Solution Approach 1:
The drum mechanism provides dynamic security through rotational movement. The drum rotates to different positions (loading position aligned with input opening, unloading position aligned with secure storage) based on operational needs. This dynamic positioning provides security without requiring complex static locking mechanisms at all times.
Solution Approach 2:
The drum mechanism serves multiple functions: it acts as a receiving chamber, a transfer mechanism, and a security barrier. By combining these functions into a single component, the design avoids adding separate complex locking mechanisms, thus maintaining security while limiting complexity increase.
3Object-affected harmful factors
If a rotatable drum mechanism is implemented, then access restriction is improved, but ease of operation worsens
Solution Approach 1:
The delivery door and drum mechanism are merged into a coordinated system where a single user action (opening/closing the delivery door) simultaneously controls both the access path and the drum position. This merging ensures that access control and operational simplicity are achieved together through unified design.
Solution Approach 2:
The linking mechanism automatically coordinates the drum rotation with delivery door movement without requiring separate user actions. When the user opens or closes the delivery door, the linking mechanism self-adjusts the drum to the appropriate position, providing access control while maintaining operational simplicity.
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 solution effectively prevents unauthorized access by ensuring a circuitous path for access, preventing parcels from getting stuck, and providing secure storage, thus enhancing security against theft and vandalism.
Implementation Method 1
The linking mechanism comprises a first gear fixed to the delivery door and a second gear fixed to the drum. The first gear mates with the second gear such that rotation of the first gear in the first rotational direction causes the second gear to rotate in the opposite rotational direction.

AI summary
A delivery receptacle for receiving objects, such as parcels, has a housing having an input opening, a delivery door rotatably coupled to the housing for opening and closing the input opening, and a drum rotatably coupled to the housing and having a drum access opening accessible through the input opening. The delivery door is mechanically coupled to the drum such that rotation of the delivery door in a first rotational direction causes rotation of the drum in the opposite rotational direction. The delivery door is rotatable between an open position in which the drum is oriented with the drum access opening aligned with the input opening such that a parcel can be inserted into the drum, and a closed position in which the drum is oriented with the drum access opening aligned with a drop area such that a parcel will exit the drum and enter the drop area.
