Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If wireless sensors and transceivers are used for engine monitoring, then device complexity is reduced and weight is decreased, but measurement precision and data reliability may be compromised
Solution Approach 1:
The patent replaces the mechanical wiring system with a wireless communication system. Wireless sensors transmit engine parameter data and emission data via radio frequency signals to the processor, eliminating the need for physical wire connections while maintaining data acquisition capabilities.
Solution Approach 2:
The wireless transceiver serves multiple functions: it transmits engine operating parameters, emission data, and alarm signals bidirectionally between sensors/processor and the ground-based receiver, replacing multiple dedicated wiring systems with a single multi-functional wireless communication interface.
2Object-affected harmful factors
If real-time monitoring and processing of emission data is implemented, then environmental compliance is improved, but use of energy and device complexity increase
Solution Approach 1:
The processor continuously compares emission data against predetermined threshold values in real-time, generating alarm signals before excessive emissions occur. This preliminary detection and warning system enables preventive action to maintain environmental compliance.
Solution Approach 2:
The system performs automated monitoring, data processing, and alarm generation without requiring continuous human intervention. The processor autonomously analyzes emission data and triggers alerts when thresholds are exceeded, reducing the need for external energy-intensive monitoring infrastructure.
3Reliability
If deterministic communication protocols are used for wireless data transmission, then reliability is improved, but adaptability and real-time responsiveness deteriorate
Solution Approach 1:
The system implements bidirectional communication where the processor receives emission data from sensors and sends alarm signals to the ground-based receiver in real-time. This feedback loop enables the system to adapt to changing engine conditions and emission levels dynamically while maintaining reliable data transmission.
Solution Approach 2:
The wireless communication system operates dynamically, adjusting data transmission and processing based on real-time engine operating conditions. The processor can generate alarm signals immediately when emission thresholds are exceeded, providing real-time adaptability without relying on fixed deterministic schedules.
