Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If communication range is determined based on service requirements and mapping information, then communication reliability is improved, but device complexity increases due to additional determination processes
Solution Approach 1:
The patent introduces mapping information as an intermediary element that connects service requirements to communication range determination. Instead of directly calculating communication range from raw service parameters, the system uses pre-established mapping relationships (e.g., service types mapped to standard communication ranges) to simplify the determination process while maintaining reliability.
Solution Approach 2:
The patent transforms the communication range determination from a complex calculation based on raw service parameters to a parameter lookup process using mapping information. By changing the approach from computational derivation to parameter mapping, the system reduces device complexity while preserving communication reliability through standardized range values.
2Reliability
If position-based communication range determination is implemented, then data exchange reliability is improved, but processing time increases
Solution Approach 1:
The patent performs preliminary action by pre-establishing mapping information that associates service requirements with standard communication ranges before actual communication occurs. This pre-processing eliminates the need for real-time complex calculations during data exchange, reducing processing time while maintaining reliability through predetermined range values.
Solution Approach 2:
The patent uses copying by referencing pre-defined standard communication ranges from mapping information rather than calculating unique ranges for each service instance. This approach copies established range values to appropriate services, avoiding redundant computations and reducing processing time while ensuring reliable data exchange within known communication boundaries.
