Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single information channel is used for signal transmission, then the device complexity is reduced, but the safety and reliability are insufficient
Solution Approach 1:
The information transmission is divided into two separate channels: a first information channel for transmitting a first signal encoding a measured quantity, and a second information channel for transmitting a second signal encoding the same or related measured quantity. This segmentation allows independent verification of measurements through multiple pathways, enhancing safety without requiring complete system redesign
Solution Approach 2:
The system implements feedback by transmitting the same measured quantity information through two different channels. The receiver can compare the first signal and second signal to verify measurement accuracy, creating a self-checking mechanism that improves reliability while maintaining manageable system complexity
2Reliability
If multiple information channels are implemented for verifying measured quantities, then safety and reliability are improved, but the device complexity increases
Solution Approach 1:
The induction system performs multiple functions through the dual-channel architecture: primary energy transfer, measurement transmission via first channel, verification transmission via second channel, and automatic comparison/validation. This multi-functionality approach consolidates safety verification into the existing energy transfer infrastructure, avoiding the need for entirely separate verification systems
3Reliability
If signal verification through multiple channels is implemented, then malfunctions are reduced, but the ease of operation may be affected
Solution Approach 1:
The system performs self-verification by automatically comparing measurements transmitted through the first information channel with those transmitted through the second information channel. This self-service validation mechanism operates autonomously without requiring user intervention, maintaining ease of operation while significantly improving functional reliability through continuous verification
