Solution Overview

Problem

Current thermal containers used in drone transport of special materials like organic and medical materials fail to reliably maintain precise temperature conditions, especially under varying external climatic conditions and extended flight times, as they do not account for energy consumption related to temperature maintenance, posing risks in compliance with regulatory requirements.

Innovation Solution

A thermal container integrated with a control unit, insulating casing, temperature sensors, and a thermal unit that calculates and adjusts energy usage for both motor and temperature control, allowing real-time monitoring and modification of temperature and energy levels, enabling the drone to assess and adjust mission parameters to ensure compliance with thermal conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If simple insulating containers are used for thermal transport, then device complexity is reduced, but temperature control reliability deteriorates under varying climatic conditions and extended flight times

Engineering Contradiction:
Improvecontainer structureVSAvoidtemperature control
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The control unit automatically monitors temperature via sensors and activates the thermal unit only when needed to maintain the predetermined temperature range, allowing the system to self-regulate without constant external intervention while ensuring reliable temperature control

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system dynamically adjusts the operation of the thermal unit based on real-time temperature measurements and environmental conditions, changing operational parameters (activation/d deactivation) to maintain temperature reliability without requiring complex continuous control mechanisms

Inventive Principle:
Principle #35Parameter changes

2Productivity

If extended flight times are implemented to increase transport autonomy, then productivity is improved, but energy consumption increases making temperature maintenance difficult

Engineering Contradiction:
Improvetransport autonomyVSAvoidenergy consumption
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The thermal unit operates periodically rather than continuously - the control unit monitors temperature and activates the thermal unit only when the temperature deviates from the predetermined range, reducing overall energy consumption while maintaining temperature control during extended flights

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

Temperature sensors provide continuous feedback to the control unit, which adjusts thermal unit operation accordingly. This closed-loop control ensures energy is consumed only when necessary to maintain temperature, enabling extended flight times without compromising thermal conditions

Inventive Principle:
Principle #23Feedback

3Reliability

If thermal unit is continuously activated to maintain temperature, then temperature control reliability is improved, but energy consumption increases reducing flight autonomy

Engineering Contradiction:
Improvetemperature maintenanceVSAvoidflight time
Core Design Contradiction:
ReliabilityVSDuration of action of moving object

Solution Approach 1:

The thermal unit operates periodically based on actual temperature needs rather than continuously. The control unit monitors temperature and activates the thermal unit only when the predetermined temperature range is approached or exceeded, maintaining reliability while conserving energy for extended flight duration

Inventive Principle:
Principle #19Periodic action
