Solution Overview

Problem

Existing monitoring techniques for detecting environmental anomalies within shipping containers are often delayed due to remote sensor placement, leading to risks of rapid environmental damage and potential harm during transportation, especially for hazardous materials like lithium-based batteries.

Innovation Solution

The implementation of an enhanced shipping container apparatus with integrated fire suppression systems and a wireless node network that includes sensor-based ID nodes and a command node. This system detects environmental anomalies, such as temperature thresholds, and initiates a layered alert notification to trigger a mediation response, including the automatic release of fire suppressant material.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If remote sensor placement is used for monitoring, then device complexity is reduced, but detection speed and response time deteriorate

Engineering Contradiction:

Core Design Contradiction:

Device complexityVSSpeed

Solution Approach 1:

The monitoring system is segmented into multiple independent wireless sensor nodes distributed throughout the container. Each node independently monitors its local environment, enabling rapid detection without complex centralized wiring while maintaining system simplicity through modular deployment

Inventive Principle:

Principle #1Segmentation

2Reliability

If integrated fire suppression panels are added to container walls, then fire suppression capability is improved, but device complexity increases

Engineering Contradiction:

Improvefire suppression capabilityVSAvoidcontainer structure complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The fire suppression functionality is merged directly into the container wall panels themselves. The panels contain fire suppressant material and temperature-sensitive release mechanisms integrated within the wall structure, eliminating the need for separate suppression systems while enhancing fire protection capability

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The fire suppression panels utilize temperature-sensitive materials that automatically trigger suppressant release when exposed to fire conditions. This self-activating mechanism eliminates complex control systems, sensors, and power requirements while ensuring reliable fire suppression response

Inventive Principle:

Principle #25Self-service

3Measurement precision

If wireless node network with multiple sensors is implemented, then measurement precision is improved, but use of energy increases

Engineering Contradiction:

Improveenvironmental anomaly detection precisionVSAvoidenergy consumption

Core Design Contradiction:

Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The wireless sensor nodes operate in periodic measurement cycles rather than continuous monitoring. Sensors activate at intervals to collect environmental data, then enter low-power sleep mode. This periodic operation maintains detection precision across multiple nodes while significantly reducing overall energy consumption of the network

Inventive Principle:

Principle #19Periodic action

AI summary

An enhanced shipping container apparatus that maintains packages is described having integrated fire suppression. The apparatus has a container base supporting the packages, multiple container walls coupled to the container base, and a container top coupled to each of the container walls. A fire suppression panel is integrated as part of one or more of the walls and top portion, and has a support sheet of fire resistant material; an interior exposed sheet of temperature sensitive material; a sealed boundary connecting the support sheet and interior exposed sheet on peripheral edges (where the sealed boundary, support sheet and interior exposed sheet define a holding cavity), and integrated fire suppression material in the holding cavity. The temperature sensitive material of the interior exposed sheet releases the integrated fire suppressant material from within the holding cavity when the temperature sensitive material of the interior exposed sheet is exposed to a threshold temperature.
