Collapsible Package Receiving Box with Movable Joints to Reduce Theft
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Package theft is a common issue due to packages being left in visible and accessible locations, particularly during the holiday season, as existing solutions do not effectively provide a secure and space-efficient means to store packages.
Innovation Solution
A collapsible package delivery box system that expands from a compact state to a larger state, featuring movable joints and a locking mechanism, allowing secure storage with a ratio of expanded volume to collapsed volume between 3 and 15, and can be secured to external structures, with optional integration with a fixed box structure for additional storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a package receiving system is designed to provide secure storage, then package theft prevention is improved, but the system occupies more space when not in use
Solution Approach 1:
The package receiving system employs movable joints connecting the cover, back wall, side walls, and bottom wall, enabling the structure to dynamically transition between a collapsed low-profile state for space efficiency and an expanded state for secure package storage. This dynamic configuration allows the system to adapt its volume based on operational needs while maintaining security functionality.
Solution Approach 2:
In the collapsed state, the side walls and bottom wall are received within the interior volume defined by the cover and back wall, creating a nested configuration. This nesting principle allows the expandable structure to be compactly stored within its own collapsed form, minimizing the space occupied when the package receiving system is not in use while still providing secure storage when expanded.
2Volume of stationary object
If a package receiving system is designed to accommodate larger packages, then storage capacity is improved, but the profile height increases when collapsed
Solution Approach 1:
The package receiving system is divided into segmented walls (cover, back wall, side walls with first and second sections, and bottom wall) connected by movable joints. This segmentation allows each component to be independently positioned, enabling the structure to collapse into a compact low-profile configuration while still providing sufficient storage capacity when expanded. The segmented design facilitates the ability to accommodate various package sizes without increasing the collapsed height.
3Reliability
If a locking mechanism is added to secure the cover, then security is improved, but device complexity increases
Solution Approach 1:
The locking mechanism is configured to secure the cover to the front wall through self-contained engagement between a first engagement mechanism on the cover and a second engagement mechanism on the front wall. This self-service design provides security functionality while minimizing external complexity, as the locking components are integrated into the existing structure rather than requiring separate complex locking systems.

AI summary
A package receiving system includes a cover, a back wall coupled to the cover by a movable joint, a first side wall, a second side wall, a bottom wall, and a front wall. The package receiving system is movable from a collapsed state to an expanded state.
