Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing receiving assemblies for unattended delivery lack secure and efficient mechanisms for authenticating and managing access, particularly for unmanned deliveries, as they often rely on less secure methods like magnetic locks and remote access codes.
Innovation Solution
A secure delivery receiving assembly featuring a housing with a hinged door, a locking unit, keypad, microprocessor, alarm, camera, fingerprint scanner, and transceiver, which allows for secure entry of codes, biometric authentication, and wireless communication to manage access and notify users of deliveries.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If magnetic locks and remote access codes are used for unattended delivery, then ease of operation is improved, but security and reliability deteriorate
Solution Approach 1:
The patent replaces mechanical locking systems with electronic keypad and microprocessor-based authentication systems. The mechanical lock is substituted by an electronic locking mechanism controlled by the microprocessor 44, which processes authentication codes entered via keypad 42, thereby improving security while maintaining ease of operation through electronic control.
Solution Approach 2:
The delivery receiving assembly enables self-service through automated authentication and locking mechanisms. The microprocessor 44 automatically verifies codes entered on the keypad 42 and actuates the locking unit 40 without requiring manual intervention, allowing unattended delivery while maintaining security through automated security protocols.
2Device complexity
If basic locking mechanisms are used, then device complexity is reduced, but security and authentication capability deteriorate
Solution Approach 1:
The patent combines multiple security functions into a single integrated system. The microprocessor 44 merges code authentication, biometric scanning via fingerprint scanner 58, camera surveillance 54, and locking control into one coordinated system, providing enhanced security without proportionally increasing device complexity through integration.
Solution Approach 2:
The locking unit 40 serves multiple functions: it mechanically secures the door, responds to electronic authentication signals from the microprocessor 44, and integrates with the alarm system 48. This multi-functionality provides comprehensive security while avoiding the need for separate dedicated components for each security function.
3Device complexity
If no alarm system is implemented, then device complexity is reduced, but security and detection of unauthorized access deteriorate
Solution Approach 1:
The alarm system 48 provides feedback when unauthorized access attempts are detected. The microprocessor 44 monitors authentication attempts via the keypad 42 and triggers the alarm 48 when incorrect codes are entered, creating a feedback loop that deters unauthorized access while maintaining relatively simple system architecture.

AI summary
A delivery receiving assembly for enabling secure unattended delivery of an item includes a housing, which has an opening positioned therein. A door is hingedly engaged to the housing and is positioned to cover the opening. A locking unit, which is engaged to one of the housing and the door and is selectively engageable to the other of the housing and the door, is positioned to secure the door over the opening. A keypad is engaged to one of the housing and the door. A microprocessor is engaged to the housing and is operationally engaged to the keypad and the locking unit. Upon entry of a code into the keypad, the microprocessor actuates the locking unit to unlock the door. An alarm is engaged to the housing and is operationally engaged to the microprocessor. The microprocessor selectively actuates the alarm upon entry of an incorrect code into the keypad.
