Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If two data lines are used for data transmission and reception between burning tool and tire pressure monitoring device, then data transmission capability is improved, but port installation cost and device complexity increase
Solution Approach 1:
The patent combines transmission and reception functions into a single data line. The burning tool and tire pressure monitoring device share a common data line where one device transmits while the other receives, and then roles reverse. This merging eliminates the need for separate dedicated TX and RX lines, reducing port requirements while maintaining full bidirectional communication capability.
Solution Approach 2:
The system dynamically switches the function of the single data line between transmission and reception modes. Through controlled switching of transmission/reception states at different time periods, the system achieves bidirectional communication on a unidirectional physical line, reducing hardware complexity while preserving full data exchange capability.
2Reliability
If two data lines are used for data transmission and reception, then communication reliability is improved, but ease of operation deteriorates due to connection requirements
Solution Approach 1:
By merging transmission and reception into a single shared data line, the system reduces the number of connections required from two dedicated lines to one shared line. This simplifies the physical connection process while maintaining communication reliability through time-division multiplexing of transmission and reception functions.
Solution Approach 2:
The system automatically manages the switching between transmission and reception modes without requiring manual configuration or complex connection procedures. The burning tool and tire pressure monitoring device self-coordinate their communication roles, eliminating the need for precise manual port matching and reducing operational complexity.
3Adaptability or versatility
If additional data ports are added to increase transmission/receiving capability, then data communication flexibility is improved, but manufacturing cost increases
Solution Approach 1:
The single data line serves multiple functions by dynamically switching between transmission and reception roles. This multi-functional approach provides the same communication flexibility as separate dedicated lines would offer, while requiring fewer physical ports and reducing manufacturing complexity and cost.
