Solution Overview

Problem

Existing heat-generating devices, such as portable battery-operated radios, transfer heat to users, causing discomfort or burns, and increase the heat signature of military personnel, making them more detectable by thermal imaging.

Innovation Solution

A heat-shielding, heat-dissipating, and heat signature-reducing material layer or coating, incorporating anti-static, anti-RF, anti-EMI, and anti-corrosion materials, is applied to the interior of battery housings and electronic devices to dissipate heat and reduce the heat signature.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If heat-generating devices are used for military operations, then operational functionality is improved, but heat signature increases making personnel detectable by thermal imaging

Engineering Contradiction:

Improveoperational functionalityVSAvoidheat signature detection

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

A heat-dissipating material layer is introduced as an intermediary between the heat-generating device and the user's body. This material layer conducts heat away from the device, preventing direct heat transfer to the user while also reducing the external heat signature that would be detected by thermal imaging.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The harmful heat generated by the device is converted into a beneficial effect by using it to drive heat flow through the heat-dissipating material. The material's high thermal conductivity transforms the problematic heat into a controlled thermal management solution that protects the user and reduces detectability.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

2Ease of operation

If heat-generating devices are used, then operational capability is improved, but heat transfer to user causes discomfort or burns

Engineering Contradiction:

Improveoperational capabilityVSAvoidheat transfer to user

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The heat-dissipating material serves as a thermal intermediary that decouples the heat source from the user. It provides a controlled thermal interface that manages heat flow away from the user's body, eliminating direct heat contact while maintaining device functionality.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The thermal properties at the interface between device and user are changed by introducing material with specific thermal conductivity characteristics. This parameter change allows heat to be conducted away from the user rather than transferred directly, transforming the thermal interaction from harmful to protective.

Inventive Principle:

Principle #35Parameter changes

3Power

If heat-generating devices are used, then functional performance is improved, but heat transfer to other devices causes damage

Engineering Contradiction:

Improvefunctional performanceVSAvoiddevice integrity

Core Design Contradiction:

PowerVSReliability

Solution Approach 1:

The heat-dissipating material acts as a thermal buffer between heat-generating devices and adjacent equipment. It intercepts and conducts heat away from sensitive areas, preventing thermal damage to other devices while allowing the primary device to maintain its functional performance.

Inventive Principle:

Principle #24Intermediary (Mediator)
