Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the user terminal uses basic motion recognition for stylus pen control, then the device complexity is low, but the measurement precision of motion recognition is insufficient
Solution Approach 1:
The system performs preliminary actions by collecting motion data during a tutorial phase before actual use. The processor stores multiple motion commands and their corresponding motion data in advance, enabling accurate recognition during actual operation without requiring complex real-time analysis.
Solution Approach 2:
The system implements feedback mechanisms where the processor compares acquired motion data with stored reference motion data, and uses user feedback from tutorial phase to refine motion recognition. This iterative feedback process improves measurement precision without proportionally increasing device complexity.
2Adaptability or versatility
If the system adapts to individual user behaviors through learning, then the adaptability increases, but the loss of time for data collection and processing increases
Solution Approach 1:
The system applies partial action by focusing learning on specific motion patterns relevant to stylus pen usage rather than all possible motions. During tutorial phase, only essential motion commands are collected and stored, reducing time investment while achieving sufficient adaptability for practical use.
Solution Approach 2:
The system performs adaptation preliminarily during a dedicated tutorial phase before actual operation begins. Motion data is collected and processed in advance, so that during normal use, the system can quickly retrieve pre-processed motion commands without time-consuming analysis, thus reducing operational time loss.
3Measurement precision
If the processor analyzes all motion data in detail, then the measurement precision improves, but the productivity decreases due to processing time
Solution Approach 1:
The system segments motion analysis into two phases: tutorial phase where detailed analysis occurs to build reference data, and operation phase where simplified matching occurs. This segmentation allows comprehensive analysis when time is available (tutorial) while maintaining fast response during actual use (operation), resolving the productivity-precision trade-off.
Solution Approach 2:
The processor performs detailed motion analysis preliminarily during the tutorial phase to create comprehensive reference motion data. During actual operation, it only needs to match incoming motion data against pre-analyzed references, significantly reducing processing time while maintaining accuracy through the quality of preliminary analysis.
