Delivery door extension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current delivery methods face challenges such as unsecured packages leading to theft, inconvenience for recipients who need to be present for signature confirmation, and increased costs due to missed deliveries, especially for sensitive or high-value items, as well as privacy concerns in shared housing and unknown delivery personnel.
Innovation Solution
A delivery door extension that attaches to an existing door jamb and door, allowing secure package delivery through a controlled delivery window while maintaining electronic security system integrity, providing visual and digital confirmation of delivery, and reducing re-delivery instances by allowing package placement inside the home without granting access, with optional features like drone accommodation and data collection for analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If packages are left on the front porch for delivery, then delivery cost and time are reduced, but packages become vulnerable to theft and unauthorized access
Solution Approach 1:
The patent introduces a door extension as an intermediary structure between the door and the package. This extension creates a controlled interface where packages can be placed inside the home without the delivery person gaining access, thus resolving the contradiction between delivery efficiency and theft prevention
Solution Approach 2:
The door extension segments the door opening into two functional zones: a secure zone that remains closed to prevent unauthorized access, and a delivery zone that allows package placement. This segmentation enables simultaneous achievement of security and delivery efficiency
2Reliability
If signature confirmation is required for sensitive items, then delivery security is improved, but delivery time and cost increase due to re-delivery when recipients are unavailable
Solution Approach 1:
The door extension enables recipients to self-verify deliveries by visually inspecting packages through the transparent panel. This self-service verification mechanism eliminates the need for signature confirmation while maintaining delivery security, thus resolving the contradiction between delivery security and time loss
3Ease of operation
If the door is opened to receive delivery, then package access is enabled, but unauthorized persons gain access to the home
Solution Approach 1:
The patent extracts the package delivery function from the door opening action. The door extension allows packages to be delivered through a controlled interface without requiring the door to open, thus enabling package access while preventing unauthorized home access
4Reliability
If a delivery window is added to the door, then secure delivery is improved, but the door structure and complexity increase
Solution Approach 1:
The door extension employs a telescopic mechanism that allows the structure to dynamically adjust its width. This dynamic design enables the extension to accommodate different door openings while maintaining a compact form when not in use, thus improving secure delivery without excessive structural complexity

AI summary
A delivery door extension that attaches to an existing door jamb and engages with an existing door is provided. The delivery door extension includes a panel having a planar body with opposing front and rear surfaces extending between first and second side surfaces, a top surface, and a bottom surface, wherein the panel body includes an opening. The delivery door extension also includes a delivery window body configured to move between an open position and a closed position, a hinge mechanism attached to the first side surface of the panel, a blocking mechanism on the second side surface that restricts movement of the existing door, and a frame that includes first and second portions.
