Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If thermal energy systems are used to remove ice from the wing, then ice removal effectiveness is improved, but electricity consumption increases
Solution Approach 1:
The wing surface is divided into high critical zones and low critical zones, with different de-icing systems applied to each zone. The high critical zone uses thermal energy systems while the low critical zone uses piezoelectric vibration systems, optimizing energy consumption based on the specific de-icing requirements of each zone.
Solution Approach 2:
Different de-icing methods are applied to different zones of the wing based on their specific characteristics. The high critical zone receives thermal energy treatment while the low critical zone receives vibration treatment, creating a localized, optimized de-icing strategy that reduces overall energy consumption.
2Reliability
If electro-mechanical systems are used to remove ice from the wing, then ice removal capability is improved, but system complexity increases
Solution Approach 1:
The patent replaces complex electro-mechanical de-icing systems with a hybrid system that combines thermal energy systems and piezoelectric vibration systems. The piezoelectric devices convert electrical energy directly to mechanical vibration without complex electro-mechanical conversion mechanisms, simplifying the overall system architecture while maintaining effective ice removal capability.
3Reliability
If thermal energy is applied to the entire wing surface, then comprehensive ice protection is achieved, but energy consumption increases
Solution Approach 1:
The wing surface is segmented into high critical zones requiring thermal energy treatment and low critical zones treated with piezoelectric vibration systems. This segmentation allows comprehensive ice protection while minimizing overall energy consumption by applying the most energy-intensive thermal systems only where absolutely necessary.
Solution Approach 2:
Instead of applying thermal energy to the entire wing surface, the system applies thermal energy partially to only the high critical zones that require it most. The low critical zones are treated with the more energy-efficient piezoelectric vibration systems, achieving comprehensive protection with reduced energy consumption.
