Secured receptacle for delivery packages
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing package security solutions, such as lock boxes and tethered bags, are either bulky, create tripping hazards, or risk damaging doors due to their design, and can be easily stolen by cutting the tether.
Innovation Solution
A flexible bag receptacle system with a locking assembly that attaches to a door using tamper-resistant straps, powered by an internal module, which can be locked and unlocked electronically, preventing access without authorization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If lock boxes are used to secure packages, then package security is improved, but the device becomes bulky and occupies significant space
Solution Approach 1:
The device is divided into two main segments: a rigid locking assembly that attaches to the door structure and a flexible bag receptacle that can be collapsed when not in use. This segmentation allows the secure locking mechanism to remain compact while the package-holding portion can expand only when needed.
Solution Approach 2:
The bag receptacle is designed to be dynamic - it can expand to accommodate packages of various sizes and then collapse back to a compact state when empty. This dynamic flexibility allows the device to provide secure storage when needed while minimizing space occupation during idle periods.
2Reliability
If lock boxes are mounted near the front door, then package security is improved, but they block access to the door and create tripping hazards
Solution Approach 1:
Instead of mounting the device horizontally near the door (which would block access), the locking assembly attaches vertically to the door structure using straps that wrap around the door frame. This vertical attachment method utilizes the door's height dimension, keeping the device out of the horizontal walking path and eliminating tripping hazards.
Solution Approach 2:
The locking assembly uses flexible straps to attach to the door structure, allowing the device to conform to the door frame without protruding into the door opening or creating obstacles. The thin-profile attachment method maintains clear access to the door while providing secure mounting.
3Adaptability or versatility
If bags are attached to doors using tethers, then device flexibility is improved, but the tethers can be easily cut and the bag can be stolen
Solution Approach 1:
The locking assembly incorporates a rigid curved bar that forms part of a locking mechanism. This rigid curved structure provides structural strength and resistance to cutting or breaking, replacing the vulnerable straight tether while maintaining the ability to attach to various door configurations.
Solution Approach 2:
The attachment system combines multiple materials with different properties: rigid components for structural strength and cut resistance, flexible straps for adaptability to different door types, and tamper-resistant features. This composite approach maintains flexibility while dramatically improving theft resistance.
4Ease of manufacture
If bags are strapped to the top edge of the door, then device mounting is simplified, but packages can strike the glass and damage the door
Solution Approach 1:
The locking assembly acts as an intermediary between the bag receptacle and the door structure. It attaches to the door frame or solid portions of the door rather than directly to glass panels, distributing the load to structurally sound areas and preventing packages from striking or damaging glass surfaces.
Solution Approach 2:
The attachment points of the locking assembly are specifically positioned on the door frame or solid door portions rather than on glass areas. This localized quality ensures that the mounting structure utilizes only the strongest, most damage-resistant portions of the door assembly.

AI summary
A system and method for receiving and securing a package that is delivered to a location. A bag receptacle is provided at the door. A locking assembly engages the bag receptacle. The locking assembly can hold the bag receptacle in an open configuration and can retain and lock the bag receptacle in a closed configuration. Strapping is used to connect the locking assembly to the outside surface of a door. The strapping encircles the door. A power module is supported by the strapping on the inside surface of the door, where it can be accessed with the door closed.
