Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If acoustic sensors are continuously activated for location measurement, then measurement precision is improved, but energy consumption increases
Solution Approach 1:
The acoustic sensor activation state is dynamically adjusted based on whether the device is within a service area. The sensor is activated only when needed (within service area) and deactivated when not needed (outside service area), making the system adaptive to changing conditions rather than operating in a fixed continuous state
Solution Approach 2:
Instead of continuous activation, the acoustic sensor is activated periodically based on triggering conditions (entering service area, receiving configuration information). This periodic activation based on events reduces overall energy consumption while maintaining measurement capability when required
2Productivity
If acoustic sensors are activated based on multiple parameters (zone identifiers, reference locations, service areas, transmission periods), then location measurement efficiency is improved, but device complexity increases
Solution Approach 1:
The service area is segmented into multiple zones identified by zone identifiers, with different parameters applicable to different zones. This segmentation allows efficient location measurement within each zone while managing complexity through structured organization of parameters
Solution Approach 2:
Configuration information containing multiple parameters (zone identifiers, reference locations, service areas, transmission periods) is determined and prepared in advance before actual location measurement begins. This preliminary setup enables efficient real-time measurement without complex calculations during operation
