Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If sound control data is set to a predetermined tempo, then the automatic performance can be executed smoothly, but the flexibility for user-controlled tempo adjustments is limited
Solution Approach 1:
The patent makes the tempo control dynamic by allowing the system to switch between predetermined tempo mode and user-controlled tempo mode. The timing information is corrected based on beat positions detected from user operations, enabling real-time tempo adjustments while maintaining smooth automatic performance execution. This resolves the contradiction by making the tempo adaptable rather than fixed.
Solution Approach 2:
The patent changes the tempo parameter from a fixed predetermined value to a variable that can be adjusted based on user operations. By detecting beat positions from user inputs and correcting timing information accordingly, the system allows tempo to vary dynamically while maintaining the structural integrity of the automatic performance data.
2Measurement precision
If timing information is corrected by adding correction information to each data section, then the precision of beat position alignment is improved, but the data processing complexity increases
Solution Approach 1:
The patent divides the sound control data into multiple data sections, each corresponding to a specific time range. Timing information is corrected independently for each section by adding correction information based on detected beat positions. This segmentation approach improves beat position alignment precision while managing processing complexity by working with smaller, manageable data portions rather than processing all data at once.
Solution Approach 2:
The patent performs preliminary detection of beat positions from user operations before executing the timing correction. By pre-processing the user input data to identify beat positions and calculate correction amounts in advance, the system improves alignment precision while reducing the complexity of real-time processing during performance execution.
3Adaptability or versatility
If multiple modification modes are provided for sound control data, then the adaptability to different performance scenarios is enhanced, but the user interface complexity increases
Solution Approach 1:
The patent provides multiple modification modes (first modification mode and second modification mode) that can be selected based on different performance scenarios. The first mode corrects timing by adding correction information to data sections, while the second mode uses alternative correction methods. This multi-functionality enhances adaptability to different performance requirements while the selection interface keeps complexity manageable by allowing users to choose the appropriate mode for their needs.
