Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fire-fighting robots lack the capability to operate effectively in high-temperature environments due to inadequate thermal protection, which prevents them from entering fire sites and performing tasks such as fire extinguishing and personnel rescue efficiently.
Innovation Solution
A high-temperature-resistant fire-fighting robot is designed with a chassis system and turret system, featuring a thermal protection enclosure, high-temperature-resistant track drive, cooling circulation system, and control and sensing systems, allowing it to operate and extinguish fires in extreme temperatures by using a water cannon with integrated thermal protection and cooling mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If existing fire-fighting robots use self-spraying water mist for cooling, then certain cooling effect is achieved, but the robots cannot ensure they will not be damaged at large-scale fire sites where ambient temperature is almost 1,000°C
Solution Approach 1:
The robot system is divided into two functional segments: a thermal protection enclosure that remains closed during high-temperature transit to protect sensitive components, and an operational mode where the enclosure opens to allow water cannon deployment. This segmentation allows the robot to maintain reliable thermal protection while enabling effective fire extinguishing capability.
Solution Approach 2:
The thermal protection enclosure is designed with dynamic opening and closing capabilities, transitioning between closed state during movement through high-temperature areas and open state during fire extinguishing operations. This dynamic behavior allows the system to adapt its protection level based on operational requirements, maintaining reliability while enabling full functionality.
2Productivity
If the robot enters deep into the fire site to perform fire-extinguishing and personnel rescue tasks, then substantial help to firemen is provided, but the robot cannot achieve protection function to go deep into fire sites due to inadequate thermal protection
Solution Approach 1:
The robot applies preliminary thermal protection by maintaining the thermal protection enclosure in a closed state before and during entry into high-temperature fire sites. This preliminary protective action prevents heat damage to the robot's sensitive components, enabling it to survive and operate in environments with temperatures up to 1,000°C.
Solution Approach 2:
The thermal protection enclosure serves as a beforehand cushioning barrier that absorbs and blocks thermal radiation and convection from the fire environment. This prior cushioning protects the robot's electronic systems, battery, and control mechanisms from thermal damage, allowing deep penetration into fire zones for fire-extinguishing and rescue operations.
3Reliability
If the robot is designed with comprehensive thermal protection including thermal protection enclosure and cooling circulation system, then the robot can sustainably operate in high-temperature environments, but device complexity increases
Solution Approach 1:
The cooling circulation system is extracted as a separate, dedicated subsystem with its own cold source, heat exchanger, and coolant circulation loop. This extraction allows the cooling function to be independently optimized and managed, reducing the thermal burden on the main robot systems and enabling sustainable operation in high-temperature environments through specialized thermal management.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The robot can sustainably operate and extinguish fires in high-temperature environments, enhancing fire-fighting efficiency and reliability by providing comprehensive thermal protection for both the chassis and water cannon, overcoming previous limitations of existing robots.
