Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a single find location technique is used regardless of environment, then device complexity is reduced, but measurement precision deteriorates
Solution Approach 1:
The system dynamically selects find location techniques based on detected physical environmental conditions. The apparatus transitions between different location methods (e.g., GPS-based vs. Wi-Fi-based techniques) depending on whether the environment is outdoors or indoors, ensuring optimal direction accuracy for each context while managing system complexity through adaptive rather than static configuration
Solution Approach 2:
The system changes operational parameters by selecting different find location techniques based on environmental parameters. When physical environmental conditions indicate outdoor settings, GPS-based techniques are selected; when indoor settings are detected, Wi-Fi-based techniques are selected. This parameter switching resolves the contradiction by adapting the measurement approach to environmental context
2Measurement precision
If environmental conditions are considered and multiple techniques are selected, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The system performs preliminary detection of physical environmental conditions before selecting a find location technique. By detecting whether the apparatus is indoors or outdoors in advance, the system can pre-determine the appropriate location method, avoiding complex real-time switching and reducing overall system complexity while maintaining high measurement precision
Solution Approach 2:
The system uses feedback from environmental condition detection to select appropriate find location techniques. The detection apparatus provides feedback about the physical environment, which informs the selection of GPS-based or Wi-Fi-based techniques, creating a closed-loop system that achieves high accuracy without requiring complex manual configuration
3Reliability
If physical environmental conditions are detected and techniques are adapted, then reliability is improved, but ease of operation deteriorates
Solution Approach 1:
The system performs self-service by automatically detecting physical environmental conditions and selecting appropriate find location techniques without user intervention. The apparatus autonomously determines whether to use GPS-based or Wi-Fi-based techniques based on its detected environment, eliminating the need for users to manually configure location settings while ensuring reliable direction generation
