1Measurement precision

If conventional motion capture technologies are used, then motion data can be collected, but accurate evaluation of motion performance is difficult due to variability in human performance and limitations in processing power

Engineering Contradiction:
Improvemotion evaluation accuracyVSAvoidprocessing capability requirements
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent replaces complex mechanical motion capture processing systems with machine learning-based audio feedback engines that analyze motion data through learned patterns. The system substitutes traditional physics-based motion analysis with neural network models that have been trained to recognize correct versus incorrect motion patterns, thereby reducing computational complexity while improving evaluation accuracy.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system employs self-learning capabilities where the audio feedback engine continuously improves its motion evaluation accuracy by learning from feedback data. The machine learning models adapt and refine their understanding of correct motion patterns through exposure to labeled examples, enabling the system to serve itself by automatically improving its evaluation capabilities without requiring manual recalibration or complex processing adjustments.

Inventive Principle:

If traditional feedback mechanisms are used, then basic motion guidance can be provided, but adaptive and personalized feedback is difficult to achieve

Engineering Contradiction:
Improvefeedback adaptabilityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a closed-loop feedback system where the audio feedback engine receives labeled feedback data about correct and incorrect motions, processes this information through machine learning models, and generates adaptive feedback recommendations. The system continuously cycles through collecting motion data, evaluating it against learned patterns, providing feedback, and using the results to further refine its evaluation criteria, thereby achieving high adaptability through iterative learning.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The feedback mechanism transitions from static, pre-programmed responses to dynamic, adaptive feedback that evolves with each interaction. The machine learning models adjust their parameters and decision boundaries based on incoming feedback data, allowing the system to adapt its behavior in real-time. This dynamic adaptation enables personalized feedback strategies that respond to individual user performance patterns without requiring complex manual configuration.

Inventive Principle:

3Measurement precision

If extensive processing power is allocated to analyze motion data, then more detailed evaluation is possible, but processing time and computational resources increase

Engineering Contradiction:

Solution Approach 1:

The system performs preliminary action by pre-training machine learning models on extensive datasets of correct and incorrect motion patterns before deployment. During actual motion evaluation, the pre-trained models can quickly compare incoming motion data against learned patterns without requiring intensive real-time computation. This preliminary learning phase transfers computational burden from runtime processing to offline training, enabling detailed evaluation at low processing cost during actual use.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent employs parameter changes by adjusting the complexity and granularity of motion analysis based on computational constraints and performance requirements. The machine learning models can dynamically select analysis depth and detail level by modifying activation thresholds, feature extraction parameters, or evaluation granularity. This allows the system to maintain high measurement precision when needed while reducing processing time during routine evaluations by operating at optimized parameter settings.

Inventive Principle:
