Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If players train independently without a coach, then training accessibility is improved, but training quality and feedback effectiveness deteriorate

Engineering Contradiction:
Improvetraining accessibilityVSAvoidfeedback quality
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The system implements continuous feedback loops where sensors detect puck position, stickhandling actions, and shooting parameters, then provide real-time digital feedback through mobile devices. This automated feedback mechanism replaces the informational gap previously filled only by human coaches, enabling independent players to receive actionable performance insights without losing critical feedback quality.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent introduces a digital intermediary system consisting of sensors, processors, and communication modules that mediate between the player's actions and the feedback delivered. This intermediary captures raw performance data, processes it through algorithms, and transforms it into meaningful feedback, bridging the gap between independent training and coached training.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of information

If real coaches provide feedback during training sessions, then feedback quality is improved, but cost and time availability deteriorate

Engineering Contradiction:
Improvefeedback qualityVSAvoidtraining availability
Core Design Contradiction:
Loss of informationVSLoss of time

Solution Approach 1:

The system enables players to conduct self-service training with automated digital coaching capabilities built into the training equipment itself. The smart puck and associated sensors automatically monitor performance metrics and provide feedback without requiring external coach intervention, making high-quality feedback continuously available regardless of coach availability or cost constraints.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces the mechanical system of human coach observation and verbal feedback with an automated electronic system using sensors, processors, and digital communication. This substitution eliminates the time and cost constraints associated with human coaches while maintaining or improving feedback quality through continuous automated monitoring and analysis.

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

3Productivity

If digital feedback systems are implemented, then training scalability is improved, but measurement precision and responsiveness deteriorate

Engineering Contradiction:
Improvetraining scalabilityVSAvoidperformance detection accuracy
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

The system segments the performance measurement task across multiple specialized sensors distributed throughout the training equipment. Rather than relying on a single generic sensor, the patent employs specific sensors for detecting puck position, stick angle, shot velocity, and other parameters, with each sensor optimized for its specific measurement function. This segmentation enables both high precision and system scalability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent utilizes changes in physical parameters detected by sensors (such as position, velocity, acceleration, and orientation) to derive detailed performance metrics. By monitoring multiple parameters simultaneously and analyzing their relationships, the system achieves high measurement precision while maintaining scalability through software-based analysis that can handle increasing amounts of data without proportional increases in hardware complexity.

Inventive Principle:
Principle #35Parameter changes
