Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for measuring and comparing exercise performance, such as running or sailing, are inaccurate and difficult to use, especially in environments affected by wind or topography, as they require manual timing and distance measurement, and do not provide real-time feedback on progress towards set goals.
Innovation Solution
A device and method that uses a communication interface, processor, and memory to receive and compare activity data with environmental data, such as wind and topography information, to provide feedback to users on their performance relative to previous activities, utilizing sensors like anemometers and satellite positioning devices for accurate data collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual timing and distance measurement methods are used, then device complexity is reduced, but measurement precision deteriorates
Solution Approach 1:
The patent introduces environmental parameters (wind speed, temperature, pressure, humidity) as intermediary variables that mediate between the exerciser's actual performance and the measured performance. These environmental factors serve as mediators to correct and adjust the raw measurement data, thereby improving measurement precision without requiring complex direct measurement instruments.
Solution Approach 2:
The system implements feedback by continuously monitoring environmental parameters and using them to adjust performance measurements in real-time. The measured performance data is fed back through environmental condition analysis to provide corrected performance metrics, enabling continuous improvement of measurement accuracy without increasing device complexity.
2Measurement precision
If environmental parameters are taken into account, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent applies multi-functionality by using a single data processing system that handles both traditional performance measurement and environmental parameter analysis. The same processor and memory units that store performance data also process environmental corrections, eliminating the need for separate complex measurement devices and reducing overall system complexity while maintaining high measurement precision.
3Ease of operation
If real-time feedback is provided, then ease of operation is improved, but loss of time in data processing increases
Solution Approach 1:
The system performs preliminary action by pre-storing environmental parameter ranges and correction algorithms in memory before the exercise session begins. During the actual exercise, the processor simply retrieves pre-computed correction factors and applies them to real-time performance data, enabling instant feedback without time-consuming calculations, thus maintaining ease of operation while minimizing data processing time.
