Solution Overview

Problem

Current smart home systems lack comprehensive solutions for secure package delivery management, as they do not effectively integrate delivery information analysis and feedback mechanisms to control access to secure areas within the smart environment.

Innovation Solution

The implementation of intelligent, multi-sensing, network-connected devices that communicate with each other and a central server or cloud-computing system to detect delivery information, provide feedback to deliverers, and manage secure area access through a method involving entryway interface devices, hazard detectors, wall switches, and doorbells, enabling secure package handling and access control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If automated package delivery handling is implemented, then delivery efficiency is improved, but security risk increases

Engineering Contradiction:
Improvedelivery efficiencyVSAvoidsecurity risk
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The system implements a feedback mechanism where the computing system receives delivery information from smart devices, analyzes it, and provides drop-off feedback to the deliverer. This closed-loop feedback system ensures that automated delivery is coordinated with security protocols, allowing efficient delivery while maintaining security through continuous monitoring and verification.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The computing system acts as an intermediary between the deliverer and the secure area. It receives delivery information, processes it against security criteria, and only then enables access to the secure area. This intermediary role allows automated delivery handling while maintaining security control through centralized decision-making.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If access to secure area is enabled for delivery, then delivery convenience is improved, but security control deteriorates

Engineering Contradiction:
Improvedelivery convenienceVSAvoidsecurity control
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system performs preliminary analysis of delivery information before enabling access to the secure area. The computing system receives and analyzes delivery information in advance, verifies it against security criteria, and only then provides drop-off feedback that enables access. This preliminary action ensures convenience is granted only after security verification.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The access control system is dynamic rather than static. Access to the secure area is temporarily enabled based on verified delivery information and automatically disabled after the drop-off action is detected. This dynamic approach provides convenience during the delivery window while maintaining security control overall.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If multiple smart devices are integrated for delivery management, then system functionality is improved, but device complexity increases

Engineering Contradiction:
Improvesystem functionalityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system employs multiple smart devices (entryway interface device, hazard detector, wall switch, doorbell) that can serve both their primary security functions and delivery management functions. This multi-functionality approach enhances system versatility without requiring entirely separate dedicated delivery devices, thereby limiting the increase in overall complexity.

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

Solution Approach 2:

The computing system merges the functionality of multiple smart devices into a unified delivery management process. It coordinates information from various devices, processes it centrally, and provides coordinated control signals. This merging approach allows comprehensive delivery management functionality while maintaining manageable complexity through centralized coordination.

Inventive Principle:
Principle #5Merging (Combining)
