Anti-theft device for a package
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large packages often left unattended at residences are vulnerable to theft, as recipients cannot be present for delivery and existing security measures are inadequate, resulting in significant annual losses for shippers, carriers, and customers.
Innovation Solution
An anti-theft device comprising a locking ball mechanism with an exterior mounting plate, a slotted tube, and a locking rod device that secures packages to a stationary object, preventing unauthorized removal and allowing delivery personnel to insert packages without removing the locking head.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If packages are left unattended at residences for delivery, then delivery productivity is improved, but packages become vulnerable to theft
Solution Approach 1:
The patent applies preliminary anti-action by installing a locking mechanism on the package before delivery. The locking mechanism includes a locking ball device with an exterior mounting plate that can be secured to the package, and a locking rod device with a slotted tube that engages with the locking ball. This pre-installed security system prevents theft before the package is left unattended, allowing delivery personnel to leave packages safely without requiring recipient presence.
2Object-affected harmful factors
If a locking mechanism is installed on the package, then theft prevention is improved, but device complexity increases
Solution Approach 1:
The locking mechanism is segmented into distinct functional components: an exterior mounting plate with a locking ball device for attachment to the package, a separate locking rod device with a slotted tube and locking head, and a key-operated locking head. This segmentation allows each component to perform its specific function independently while maintaining overall system simplicity. The modular design makes the mechanism easier to manufacture, install, and maintain compared to an integrated complex system.
3Reliability
If the locking head is secured to the slotted tube, then security is improved, but ease of operation for delivery personnel deteriorates
Solution Approach 1:
The slotted tube acts as an intermediary component between the locking ball device and the locking head. The slots in the tube allow the locking head to move along a predetermined path during the locking and unlocking operations. This intermediary structure guides the mechanical interaction between components, enabling delivery personnel to easily insert and remove packages by simply operating the locking head, while maintaining secure locking when engaged. The key-operated locking head provides security without complicating the basic operation.

AI summary
An anti-theft device for a package is a two-part securing mechanism for packages. The first part is a ball that is attached to the package at the order processing facility. The second part is a matching locking rod with an integral locking mechanism. This locking rod is in turn securely fastened onto a stationary object like a railing, porch post, or other fixed object. The look may be opened by use of a key.
