Chain-Based Secure Device for Adaptable Package Delivery Binding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing problem of package theft during delivery, particularly in scenarios where package pick-up stations are unavailable or full, and personal delivery boxes are inadequate for various package sizes.
Innovation Solution
A secure device using chains with high structural strength, a limiting frame, and a lock system that can bind packages of different sizes by adjusting the lock position, ensuring secure and universal packaging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a full-enclosure personal delivery box is used, then package security is improved, but device complexity and space occupation increase
Solution Approach 1:
The patent extracts the essential security function from the full-enclosure box design. Instead of using a complete enclosed box, the invention uses only the necessary chain binding mechanism with a limiting frame, removing unnecessary enclosure structures while maintaining security effectiveness.
Solution Approach 2:
The patent employs simple, inexpensive chain links and a basic locking mechanism rather than complex durable box structures. The chain binding system uses readily available, cost-effective components that provide adequate security without the complexity and cost of enclosed boxes.
2Device complexity
If a fixed-size personal delivery box is used, then device complexity is reduced, but adaptability to different package sizes deteriorates
Solution Approach 1:
The patent introduces dynamic adjustability through chains of varying lengths and multiple locking positions. The chain system can be configured to accommodate different package dimensions by adjusting chain length and lock position, providing versatility without requiring multiple fixed-size boxes.
Solution Approach 2:
The patent changes the parameter of chain length and lock position to adapt to different package sizes. By varying these parameters, the same basic device structure can securely bind packages of different dimensions, eliminating the need for multiple fixed-size enclosures.
3Reliability
If multiple chains are used to bind the package, then security against theft is improved, but device complexity increases
Solution Approach 1:
The patent merges multiple chain links into a unified binding system controlled by a single locking mechanism. The limiting frame integrates multiple chains, and one lock can secure all chains simultaneously, providing enhanced security while minimizing operational complexity.
Solution Approach 2:
The locking mechanism serves multiple functions: it secures all chains simultaneously, can be positioned at different locations along the chains, and works with packages of various sizes. This multi-functionality provides high security without proportionally increasing device complexity.

AI summary
Embodiments of the present disclosure provide a secure device for package delivery, including a plurality of chains, a limiting frame, and a first lock, wherein first ends of the plurality of chains each are connected to the limiting frame and are distributed apart from each other around a periphery of the limiting frame, and the first ends of the plurality of chains are limited by the limiting frame such that portions of the plurality of chains away from the limiting frame can be pulled up to be wrapped around a package; and each chain is provided with a plurality of chain holes distributed apart from each other along its own length direction, and the first lock can successively pass through a chain hole of each of the chains to lock together the plurality of chains that are pulled up, thereby binding and locking the package.
