Lockable Package Container with Removable Door and Wall Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current package delivery systems fail to provide adequate security against theft, damaging structures, and require permanent attachments, which are inconvenient and costly for both consumers and retailers.
Innovation Solution
A lockable package container with a dual securement system that can be removably attached to either a garage door or exterior wall, featuring a securement member that traps beneath the door and a telescoping handle assembly for adjustable mounting, allowing for easy installation and use without permanent hardware, and includes optional insulation for temperature control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If direct attachment of delivery box to dwelling structure is used, then package security is improved, but structure damage and permanent attachment requirements worsen
Solution Approach 1:
The patent introduces a removable mounting system with a mounting bracket and fastening mechanism as an intermediary between the delivery box and the dwelling structure. This allows secure attachment without permanent damage, as the box can be mounted and removed using clips, latches, or adhesive mounts that preserve the integrity of the door or wall surface.
Solution Approach 2:
The mounting system is designed to be dynamic and adjustable, allowing the delivery box to be securely fixed in position when needed, yet easily removable when not required. The fastening mechanism can be engaged or disengaged on demand, providing flexibility between permanent and temporary attachment states.
2Reliability
If direct attachment of delivery box to door is used, then package security is improved, but door usability worsens
Solution Approach 1:
The mounting system allows the delivery box to be securely attached to the door when needed for package reception, yet easily removed to restore full door functionality. The dynamic fastening mechanism enables transition between secured and unsecured states, maintaining door usability.
Solution Approach 2:
The mounting system is segmented into separate components (mounting bracket, fastening mechanism, delivery box) that can be independently assembled and disassembled. This modular approach allows the box to be attached to the door without interfering with door operation, and removed when no longer needed.
3Object-affected harmful factors
If removable mounting system is used, then structure damage is prevented, but mounting security worsens
Solution Approach 1:
The mounting bracket serves as an intermediary component that provides secure attachment points on both the delivery box and the mounting surface. This intermediate structure distributes attachment forces and prevents direct damage to the door or wall while maintaining secure mounting through engineered fastening mechanisms.
Solution Approach 2:
The mounting system may utilize composite materials or combinations of materials (such as metal brackets with plastic fasteners, or adhesive compounds with mechanical clips) to achieve both secure attachment and non-damaging removal. The composite approach allows optimization of both security and preservability.

AI summary
A secure package delivery system comprises a lockable container configured for securement to a movable door or exterior wall of a building structure. The container includes a walled body and openable lid. A vertically and horizontally adjustable dolly handle assembly is slideably coupled to a rear of the body and operable to form an adjustable gap for receiving a portion of the door to trap and secure the container in place. The handle assembly is lockable in place to the container and in vertical position by a crank mechanism operated via a lever. The container further includes a movable securement aperture in the handle assembly and wall pin which permits securing the container to a wall via operation of handle assembly and crank mechanism. A movable latch operated by the crank mechanism secures the wall pin in the securement aperture to prevent removal of the container.
