Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If extensive wired cabling is used for activation, then reliability of signal transmission is improved, but device complexity and cabling redundancy increase
Solution Approach 1:
The patent replaces the mechanical wired cabling system with a wireless communication system for transmitting activation signals. The control device uses wireless transmission units to send activation signals to oxygen containers without physical cable connections, thereby eliminating cabling redundancy while maintaining reliable signal transmission through wireless protocols and signal processing mechanisms.
Solution Approach 2:
The patent introduces wireless communication as an intermediary medium between the control device and oxygen containers. Instead of direct wired connections, activation signals are transmitted through wireless electromagnetic fields, serving as a mediator that eliminates the need for extensive physical cabling while ensuring reliable signal delivery.
2Reliability
If wired cabling is used for activation, then energy supply reliability is improved, but weight and device complexity increase
Solution Approach 1:
The patent substitutes wired energy transmission with wireless energy supply mechanisms. The control device transmits activation signals wirelessly to oxygen containers, eliminating the need for heavy wired connections while maintaining reliable energy supply through efficient wireless power transmission and energy harvesting technologies.
Solution Approach 2:
The patent extracts and removes the heavy wired cabling system from the aircraft oxygen activation system. By taking out the physical cable infrastructure and replacing it with wireless communication, the system achieves weight reduction while preserving energy supply reliability through alternative wireless transmission methods.
3Reliability
If wired activation system is used, then activation signal transmission is reliable, but maintenance efficiency decreases
Solution Approach 1:
The patent replaces the wired activation system with a wireless communication system that enables easier maintenance. The control device and oxygen containers communicate through wireless signals, allowing for remote diagnostics, software updates, and system testing without requiring physical access to cable connections, thereby improving maintenance efficiency while maintaining transmission reliability.
Solution Approach 2:
The wireless system enables self-diagnostic and self-test capabilities where the control device can autonomously communicate with oxygen containers to check system status, detect faults, and perform maintenance operations without requiring manual intervention or physical cable manipulation, thus improving maintenance efficiency.
