Flexible Compartment Door Attachment for Secure In-Home Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In-home delivery services face challenges in ensuring security and privacy, as delivery personnel may enter homes when occupants are not present, potentially compromising safety and privacy, and there is a need for secure and tamper-proof compartments to manage package delivery without physical intrusion or unauthorized access.
Innovation Solution
A compartmentalized door attachment system that pivots relative to the door frame, featuring flexible materials, secure locking mechanisms, and intrusion detection systems, allowing partial entry of objects while preventing human entry, and equipped with sensors and cameras for monitoring and security alerts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If delivery personnel are allowed to enter the home for package delivery, then delivery service is provided, but security and privacy are compromised
Solution Approach 1:
The door assembly is segmented into multiple functional components: a door, a compartment that can be attached to the door or door frame, and separate locking mechanisms. This segmentation allows the delivery person to access only the compartment for package placement while the main door remains secured, providing delivery service without compromising overall security.
Solution Approach 2:
The compartment acts as an intermediary element between the delivery person and the home interior. It serves as a buffer zone where packages can be exchanged without the delivery person gaining direct access to the home, thus enabling delivery service while maintaining security through this intermediate structure.
2Measurement precision
If monitoring cameras are installed inside the home to monitor delivery, then delivery monitoring is improved, but occupant privacy is compromised
Solution Approach 1:
The compartment serves as an intermediary monitoring zone with its own camera system that can observe package delivery activities without requiring cameras inside the home. This intermediate monitoring capability provides delivery oversight while preserving occupant privacy by keeping the monitoring function external to the home interior.
Solution Approach 2:
Instead of placing cameras inside the home, the system uses cameras mounted on or near the compartment to capture delivery activities. This creates a functional copy of the monitoring capability that achieves the same objective (monitoring deliveries) without the harmful effect (privacy intrusion into the home).
3Reliability
If a compartment is added to the door assembly to prevent intrusion, then security is improved, but device complexity increases
Solution Approach 1:
The compartment is designed to perform multiple functions: it serves as a secure container for packages, a barrier to prevent intruder entry, and an attachment mechanism that can be configured in different ways (attached to door or door frame). This multi-functionality justifies the added complexity by providing several security benefits from a single structural addition.
Solution Approach 2:
The compartment is designed with dynamic attachment capabilities, allowing it to be attached to either the door or the door frame depending on the configuration needed. This dynamic adaptability provides security flexibility without requiring multiple separate components, thus managing complexity while maintaining reliability.
4Reliability
If locks are provided on both door and compartment, then access control is improved, but ease of operation deteriorates
Solution Approach 1:
Different locking mechanisms are applied to different parts of the system: the door has its own lock for main entry control, and the compartment has separate locks for package access. This local differentiation of locking qualities allows each component to be secured independently, improving access control while enabling simple, localized operation for each function.

AI summary
An entry device that is attachable to a door that pivots relative to a door frame to separate an outer area from an inner area is disclosed. The device has a compartment made of a flexible material having a first side and a second side. The flexible material has a front surface that faces the outer area and a back surface that extends into the inner area. At least one first attachment point is disposed along the first side that attaches the compartment to the door and at least one second attachment point is disposed along the second side that attaches the compartment to the door frame. According to the present invention, upon opening of the door, the compartment is configured to allow partial entry of an object to the inner area and prevent full entry by a person from the outer area. A first lock disposed along the first side configured to lock the door, wherein the first lock can be unlocked from the inner area and outer areas and a second lock disposed along the second side configured to lock the door frame, wherein the second lock can be unlocked from the inner area and outer areas.
