Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing deicing methods for airborne vehicles are inefficient in completely removing ice layers from surfaces, often leaving residual ice and requiring high power consumption.
Innovation Solution
A method and system that uses sensors to detect ice thickness and environmental conditions, employing mechanical elements to vibrate the surface and heating elements to increase temperature, allowing for the sequential removal of ice layers, with a control system managing the duration, frequency, and displacement of mechanical elements and the heating process to ensure complete deicing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If heating elements are used to remove ice layers, then ice removal effectiveness is improved, but power consumption increases
Solution Approach 1:
The deicing process is segmented into multiple stages: mechanical vibration removes the first portion of ice layer, followed by heating to remove the second portion. This segmentation allows each method to be optimized for its specific function, reducing overall power consumption while maintaining effectiveness
Solution Approach 2:
Mechanical vibration is applied as a preliminary action before heating to pre-remove a significant portion of the ice layer. This preliminary mechanical removal reduces the thickness of ice that subsequently requires thermal energy, thereby reducing total power consumption
2Reliability
If mechanical elements vibrate the surface with high frequency and displacement, then ice layer removal is improved, but device complexity increases
Solution Approach 1:
The mechanical vibration system operates at frequencies and displacements that are sufficient to remove the first portion of the ice layer, without requiring excessive parameters that would complicate the mechanical design. The vibration parameters are optimized to achieve partial removal that complements the subsequent heating process
3Measurement precision
If sensors continuously monitor ice thickness and environmental conditions, then deicing precision is improved, but device complexity increases
Solution Approach 1:
Sensors continuously monitor ice thickness and environmental conditions, providing feedback to the control system. This feedback enables real-time adjustment of vibration frequency, displacement, and heating power, optimizing the deicing process while preventing unnecessary energy consumption and simplifying control logic

Implementation Method 1
vibrating the skin surface using at least one mechanical element for a sufficient duration, sufficient frequency, and sufficient displacement so as to result in removal of a first portion of the ice layer
Implementation Method 2
heating the partially deiced skin surface using at least one heating element... heating the partially deiced skin surface results in a sufficient temperature increase in the partially deiced skin surface for removal of a second portion of the ice layer

AI summary
A method that includes receiving data from a sensor that is configured to supply data related to an ice layer thickness on a skin surface, calculating the ice layer thickness, comparing the ice layer thickness to a threshold thickness, vibrating the skin surface using at least one mechanical element for a sufficient duration, sufficient frequency, and sufficient displacement to result in removal of a first portion of the ice layer thereby resulting in at least a partially deiced skin surface, and heating the partially deiced skin surface using at least one heating element. The method further includes heating from a leading edge of the skin surface to a trailing edge of the skin surface and heating the surface to result in a sufficient temperature increase in the skin surface for removal of a second portion of the ice layer.
