Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired connection is used between sensor and engine controller, then reliable data transmission is achieved, but weight and space requirements increase
Solution Approach 1:
The patent extracts the wiring and cabling from the sensor system, eliminating the physical connection between the sensor and engine controller. The sensor becomes a standalone wireless unit that communicates with the engine controller through wireless signal transmission, thereby removing the weight and space occupation of cables while maintaining data transmission functionality.
Solution Approach 2:
The patent replaces the mechanical wired connection system with a wireless communication system. The sensor uses a wireless transceiver to transmit data to the engine controller, substituting the mechanical cable connection with electromagnetic signal transmission, thus eliminating the need for physical wiring while maintaining reliable data communication.
2Reliability
If wired connection is used between sensor and engine controller, then stable signal transmission is achieved, but space requirements increase
Solution Approach 1:
The patent removes the wiring and cabling components from the engine controller assembly, extracting the physical connection infrastructure. This eliminates the space required for cable routing, connectors, and wiring harnesses, allowing the engine controller to occupy less space while maintaining stable signal transmission through wireless communication.
Solution Approach 2:
The patent substitutes the mechanical wiring system with a wireless communication system. The engine controller incorporates a wireless receiver that communicates with the sensor through electromagnetic signals, eliminating the need for physical cable connections and reducing the space required for signal transmission infrastructure.
3Reliability
If wired connection is used, then direct data transmission is achieved, but incorrect failure indications occur due to wiring failures
Solution Approach 1:
The patent extracts the wiring system from the sensor assembly, making the sensor wirelessly connected to the engine controller. This eliminates the wiring failures that cause incorrect failure indications, as there are no physical cables that can disconnect or short circuit. The sensor can reliably indicate its operational status without the complexity of wired connections.
Solution Approach 2:
The patent replaces the mechanical wiring system with wireless communication. The sensor uses wireless signal transmission to communicate with the engine controller, eliminating the wiring failures that lead to incorrect failure indications. The wireless system provides more reliable failure detection since there are no physical connections that can malfunction.
4Weight of moving object
If wireless communication is implemented, then weight and space are reduced, but signal interference may occur
Solution Approach 1:
The patent incorporates feedback mechanisms in the wireless communication system. The sensor and engine controller can detect signal interference and adjust transmission parameters accordingly. The system monitors signal quality and can retransmit or modify signals to overcome interference, maintaining reliable communication while benefiting from the weight and space reductions of wireless technology.

AI summary
Sensors (28) are mounted to an engine (10) to detect engine conditions and send information to an engine controller (26) or other engine component through a wireless connection. Ports (30, 32) are located on the engine controller (26). An antenna assembly (40a) is plugged into one of the ports (30) and wirelessly receives the signal from the sensor (28). Another antenna assembly (40b) transmits a signal from the engine controller (26) to an external component (34). A processor (50) within the antenna assemblies (40a, 40b) monitors and adjusts the signals to correct for signal interference.
