Solution Overview

Problem

Existing package delivery systems require permanent, bulky structures that are inconvenient or not allowed in certain locations, such as apartment complexes, and do not provide adequate security for packages left unattended.

Innovation Solution

A collapsible safe box that can be removably installed and equipped with computing elements like smart locks, sensors, cameras, and alarms, allowing secure storage and access to packages.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a permanent bulky secured structure is used for package delivery, then security and reliability are improved, but device complexity and installation difficulty increase

Engineering Contradiction:
Improvepackage securityVSAvoidstructure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The safe box employs collapsible side walls that can transition between extended and retracted positions, transforming a static bulky structure into a dynamic compact form. When collapsed, the side walls parallel the back panel, reducing the overall footprint while maintaining security when extended

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The safe box is divided into modular components including the back panel, front panel, lid, bottom panel, and four separate side walls. This segmentation allows each component to be independently manufactured, assembled, and collapsed, reducing the complexity of the overall structure while maintaining security functionality

Inventive Principle:
Principle #1Segmentation

2Reliability

If a permanent secured structure is installed, then package security is improved, but ease of operation and adaptability worsen

Engineering Contradiction:
Improvepackage securityVSAvoidinstallation convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The removable engagement mechanism allows the safe box to be dynamically installed and removed from the support structure without permanent attachment. The engagement members can be inserted and secured into recesses, providing easy installation and removal while maintaining security during use

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The safe box design with standardized engagement members and recesses can be universally applied to various support structures such as doors, walls, or furniture. This multi-functionality allows the same safe box to be securely installed in different locations without requiring location-specific modifications

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Reliability

If a bulky secured structure is always present, then package security is improved, but loss of space and adaptability worsen

Engineering Contradiction:
Improvepackage securityVSAvoidstorage space
Core Design Contradiction:
ReliabilityVSVolume of moving object

Solution Approach 1:

The collapsible side walls enable the safe box to transition between an extended secure configuration and a collapsed compact configuration. When not in use, the side walls collapse parallel to the back panel, minimizing the volume occupied while maintaining the ability to provide secure storage when needed

Inventive Principle:
Principle #15Dynamics
