Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If data from various types of activities is processed using different methods depending on purpose or characteristics, then data analysis accuracy is improved, but processing complexity increases
Solution Approach 1:
The patent segments activity data processing by defining specific activity types (cycling, trekking, trail running) and applying dedicated processing methods for each. The clustering unit divides activity data into distinct categories, and the estimation unit applies specific algorithms tailored to each activity type, thereby improving analysis accuracy without requiring a single complex universal processing system.
Solution Approach 2:
The patent changes processing parameters based on activity type characteristics. Different activity types have different minimum dividing widths for data segmentation, different clustering parameters, and different power estimation formulas. This parameter adaptation allows accurate analysis for each activity while maintaining a unified processing framework.
2Measurement precision
If activity data is divided into smaller units for detailed analysis, then analysis precision is improved, but data processing time increases
Solution Approach 1:
The patent dynamically adjusts the minimum dividing width for data segmentation based on the specific activity type. For example, cycling data may use one dividing width while trail running uses another. This dynamic adjustment optimizes the balance between analysis precision and processing time for each activity type, avoiding excessive division that would increase processing time without meaningful gain.
Solution Approach 2:
Different activity types receive different levels of data division and processing detail appropriate to their characteristics. The system applies local quality principles by tailoring the granularity of data division and the complexity of analysis methods to match the specific requirements of each activity type, rather than applying uniform fine-grained division to all activities.
