Solution Overview

Problem

The increasing problem of package theft due to home deliveries, as existing solutions like alarms and cameras lack physical deterrents and available space constraints with large locking containers, necessitates a convenient and space-efficient method to secure packages.

Innovation Solution

A collapsible storage apparatus integrated into an improved doormat with an anchored frame, allowing the storage apparatus to deploy and retract, providing a secure space for packages while maintaining a compact and aesthetically pleasing design.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a large locking container is used to secure packages, then package security is improved, but space availability and aesthetics deteriorate

Engineering Contradiction:
Improvepackage securityVSAvoidspace availability
Core Design Contradiction:
ReliabilityVSArea of stationary object

Solution Approach 1:

The storage apparatus transitions from a static large container to a dynamic collapsible structure that expands when needed and collapses when not in use, allowing it to occupy minimal space during normal conditions while providing adequate storage capacity when packages need to be secured

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The collapsible storage apparatus can be nested within or integrated into the doormat structure when collapsed, effectively hiding the storage function within the aesthetic doormat form factor, thus eliminating the need for separate large containers that would occupy additional space

Inventive Principle:
Principle #7Nested doll (Nesting)

2Reliability

If a large locking container is used to secure packages, then package security is improved, but visual appearance deteriorates

Engineering Contradiction:
Improvepackage securityVSAvoidvisual appearance
Core Design Contradiction:
ReliabilityVSShape

Solution Approach 1:

The storage apparatus is merged with the doormat structure, combining the aesthetic function of a doormat with the security function of a locked container. When collapsed, the storage apparatus becomes part of the doormat's overall design, eliminating the need for separate unsightly containers

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The dynamic collapsing mechanism allows the storage apparatus to transition between a visible functional state and a hidden aesthetic state, providing security when needed while maintaining visual appeal during normal use

Inventive Principle:
Principle #15Dynamics

3Object-affected harmful factors

If alarms and cameras are used to deter theft, then deterrence is improved, but physical protection deteriorates

Engineering Contradiction:
Improvetheft deterrenceVSAvoidphysical protection
Core Design Contradiction:
Object-affected harmful factorsVSStrength

Solution Approach 1:

The solution merges multiple protective functions into a single integrated system: the collapsible storage apparatus provides physical containment, the latch mechanism provides mechanical locking, and optionally alarms or cameras can be integrated, creating a multi-layered security approach that combines both deterrence and physical protection

Inventive Principle:
Principle #5Merging (Combining)
