Solution Overview
Problem
Current performance monitoring solutions for activities involving poles, such as skiing and Nordic walking, fail to capture essential aspects of physical activity performance effectively, particularly in measuring poling power and cardiac activity simultaneously.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple sensors (force sensors, velocity sensors, cardiac activity sensors) are integrated into the pole system, then measurement precision and comprehensiveness of performance metrics are improved, but device complexity increases
Solution Approach 1:
The patent combines multiple sensors (force sensors, velocity sensors, and cardiac activity sensors) into an integrated pole system with a unified computing unit. This merging approach allows comprehensive performance measurement while managing complexity through centralized data processing and a single integrated structure rather than separate monitoring devices.
Solution Approach 2:
The pole system is designed to perform multiple functions: measuring force during poling, tracking velocity of movement, monitoring cardiac activity, and calculating performance metrics. This multi-functional design consolidates what would traditionally require separate devices into a single universal monitoring system.
2Productivity
If real-time data processing and feedback are implemented, then productivity and training efficiency are improved, but use of energy increases
Solution Approach 1:
The system processes data in real-time to provide immediate feedback on poling power, velocity, and performance metrics. This feedback mechanism enables users to adjust their technique during training sessions, improving training efficiency without requiring continuous high-energy processing of historical data.
Solution Approach 2:
The computing unit processes and outputs only the most relevant performance metrics and indicators needed for training optimization, rather than continuously analyzing all raw sensor data. This selective processing reduces energy consumption while maintaining training effectiveness.
