Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cable harnesses are installed in the aircraft floor for data communication and power supply, then reliable connection is achieved, but installation complexity and cost increase
Solution Approach 1:
The patent replaces the mechanical cable harness system with an electromagnetic induction system. The induction transmitter embedded in the aircraft seat and induction receiver in the floor (or vice versa) enable wireless power and data transmission through electromagnetic fields, eliminating the need for physical cable connections while maintaining reliable power and data supply to seat accessories.
Solution Approach 2:
The patent introduces electromagnetic induction as an intermediary mechanism between the aircraft floor and seat accessories. The induction transmitter and receiver act as mediators that transfer power and data signals without direct physical contact, replacing the traditional cable harness intermediary with a non-contact electromagnetic field intermediary.
2Reliability
If cable harnesses are installed in the aircraft floor, then power and data connection is established, but reconfiguration of aircraft cabin becomes difficult
Solution Approach 1:
By replacing the mechanical cable harness system with wireless electromagnetic induction, the patent enables easy reconfiguration of aircraft cabins. Seats can be moved, added, or removed without the constraint of fixed cable routes, as power and data are transmitted through electromagnetic fields that can be dynamically activated and deactivated based on seat position and configuration.
Solution Approach 2:
The induction-based system provides dynamic adaptability to cabin reconfiguration. The electromagnetic coupling between transmitter and receiver can be established or terminated as needed, allowing the aircraft cabin to be dynamically reconfigured for different operational requirements without permanent physical constraints imposed by cable harnesses.
3Reliability
If cable harnesses are used for connecting seat accessories, then power supply is reliable, but installation cost increases
Solution Approach 1:
The patent replaces expensive mechanical cable installation with electromagnetic induction technology. The induction transmitter and receiver units can be integrated into existing seat and floor structures without requiring extensive cable routing work, reducing installation labor costs and material expenses while maintaining reliable power supply to seat accessories.
