Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions to porch piracy, such as package delivery to work places, hiding packages, or using pickup lockers, are impractical, unreliable, or inconvenient, leaving consumers vulnerable to theft and associated financial and personal losses.
Innovation Solution
A secure delivery door kit that includes a door assembly with a keypad and locking mechanism, allowing homeowners to set a unique delivery code, ensuring packages are safely delivered and stored out of sight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If packages are delivered to the recipient's doorstep, then delivery convenience is improved, but vulnerability to porch piracy increases
Solution Approach 1:
The patent introduces a secure delivery room as an intermediary space between the exterior and the recipient's living space. Packages are delivered to this secured area through a controlled access system with keypad entry and surveillance cameras, eliminating direct doorstep delivery while maintaining convenience. The delivery room acts as a buffer zone that prevents porch pirates from accessing packages while the recipient remains indoors.
2Object-affected harmful factors
If pickup lockers are used, then theft prevention is improved, but accessibility and convenience deteriorate
Solution Approach 1:
The patent implements preliminary action by pre-establishing a secure delivery room at the recipient's residence before delivery occurs. Unlike pickup lockers that require travel to external locations, the secure room is prepared in advance at the convenient location of the recipient's home, allowing immediate access to packages without requiring trips to distant locker facilities.
3Object-affected harmful factors
If delivery drivers hide packages behind bushes or planters, then theft deterrence is improved, but reliability decreases
Solution Approach 1:
The patent implements self-service by providing automated surveillance cameras and keypad access control that operate independently of delivery driver discretion. The system automatically secures packages in the delivery room with camera monitoring and locked access, eliminating reliance on individual driver judgment and ensuring consistent, reliable security for every delivery.
4Object-affected harmful factors
If a secure delivery room with keypad access is installed, then security against porch piracy is improved, but installation complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the secure delivery system into separate functional modules: a keypad access control unit, surveillance camera system, and delivery room structure. This modular segmentation allows for staged installation and simplifies the overall implementation process, enabling homeowners to install components incrementally rather than facing a single complex installation challenge.

AI summary
A secure delivery door kit includes a door assembly, a first type of attachment mechanism, and a second type of attachment mechanism. The door assembly is configured for being installed by a user in a desired installation location (such as a wall or a garage door) and the user selects which type of attachment mechanism to use, depending on the type of installation location the user chooses. The door assembly includes a door operatively coupled to a frame such that the door is configured to move relative to the frame between an open position and a closed position. The door assembly is configured for being installed in the installation location and used for secure package delivery. The attachment mechanisms are configured for attaching the door assembly to the installation location, and the second type of attachment mechanism is different from the first type of attachment mechanism.
