Solution Overview
Problem
Conventional anti-icing technologies face challenges in accurately detecting ice formation and are economically inefficient due to high power consumption, particularly in extreme environments such as polar regions and aerospace applications.
Innovation Solution
An autonomous anti-icing apparatus that utilizes a dual redundant ice formation detection algorithm combining kinematic and aerodynamic models with electro-thermal based detection, collecting real-time data from sensing units to determine ice formation and sending heating signals to an electric heating part only when necessary, reducing power consumption and improving accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional ice formation detection algorithms are used, then the system can detect ice formation, but the detection accuracy degrades when extreme measurement values or calculated values are applied due to temporarily caused external unexpected situations
Solution Approach 1:
The system dynamically adjusts the ice formation detection algorithm by selecting between different detection methods based on current environmental conditions. When extreme values are detected, the system switches from standard detection to alternative methods, making the detection process adaptive rather than static.
Solution Approach 2:
The system changes detection parameters based on environmental conditions. When temperature, humidity, or other environmental parameters fall within normal ranges, standard detection algorithms are used. When extreme values are detected, the system modifies detection thresholds and parameters to maintain accuracy.
2Reliability
If continuous heating is applied to prevent ice formation, then ice formation is prevented, but power consumption increases significantly
Solution Approach 1:
Instead of continuous heating, the system applies heating periodically based on detected ice formation risk. Heating elements are activated only when ice formation is detected or predicted, and deactivated when conditions are favorable, creating a periodic on-off heating pattern that maintains protection while reducing energy consumption.
Solution Approach 2:
The system uses environmental data and sensor information to autonomously determine when heating is necessary, eliminating the need for continuous manual monitoring or control. The anti-icing system serves itself by automatically adjusting heating based on real-time conditions.
3Device complexity
If a single ice formation detection algorithm is used, then the system structure remains simple, but the detection accuracy degrades in extreme or unexpected environmental situations
Solution Approach 1:
The system employs multiple detection algorithms that are dynamically selected based on environmental conditions. Rather than using one fixed algorithm, the system switches between different detection methods depending on whether conditions are normal or extreme, optimizing accuracy without permanently increasing structural complexity.
Solution Approach 2:
The detection system is designed to perform multiple functions by incorporating different detection algorithms that can handle various environmental conditions. The same detection system universally handles both normal and extreme conditions by selecting appropriate algorithms, rather than requiring separate systems for each condition.

AI summary
The method of controlling an autonomous anti-icing apparatus includes: a first step of collecting and storing ice formation environment data; a second step of calculating a calculated value of an aerodynamic parameter based on the ice formation environment data and the ice formation prediction data in real time to determine whether ice formation is present on a surface of the structure and calculating a degree of ice formation through the calculated value of the aerodynamic parameter; and a third step of allowing a calculation control unit to send a temperature control signal, which includes a heating period signal, to a power supply so that an electric heating part is heated when the ice formation is determined by comparing the degree of ice formation with a preset value.
