Cross Country Course Rating System for Objective Performance Comparison
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems lack the ability to objectively compare cross-country race performances due to the absence of standardized methods for measuring course length and difficulty, making it difficult for coaches to evaluate athlete performance across different courses.
Innovation Solution
A system and method for accurately measuring cross-country course length and rating its difficulty by comparing energy costs between running on a track and a cross-country course, allowing for objective performance comparisons and conversion of cross-country times to equivalent track times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cross-country courses are used for racing, then racing variety and outdoor conditions are improved, but objective performance comparison becomes difficult due to lack of standardized measurement
Solution Approach 1:
The patent applies parameter changes by introducing a course rating system that quantifies course difficulty using specific parameters (course length, elevation gain, terrain type, surface conditions). This allows performance comparison across diverse courses by normalizing results against these measured parameters, resolving the contradiction between racing variety and measurement precision.
Solution Approach 2:
The patent uses an intermediary approach by introducing a standardized rating system that acts as a mediator between diverse course conditions and performance evaluation. The rating system translates various course characteristics into a common metric, enabling objective comparison while maintaining course diversity.
2Measurement precision
If standardized course measurement is implemented, then performance comparison accuracy is improved, but system complexity increases due to multiple measurement parameters
Solution Approach 1:
The patent applies segmentation by breaking down course measurement into distinct, manageable parameters (length, elevation, terrain, surface). Each parameter can be measured and recorded independently, then combined to form an overall course rating. This segmentation reduces system complexity by making the measurement process modular and systematic.
Solution Approach 2:
The patent uses universality by creating a multi-functional rating system that can evaluate various course types using the same set of parameters. The system is designed to handle different terrains, distances, and conditions through a unified measurement framework, avoiding the need for separate complex systems for each course type.
3Measurement precision
If course difficulty rating is calculated, then performance evaluation accuracy is improved, but energy and time resources increase for testing and data collection
Solution Approach 1:
The patent applies preliminary action by conducting course measurements and difficulty ratings in advance, before races are held. This allows the energy-intensive data collection and analysis to be performed once per course, and the resulting ratings can be used for multiple performance evaluations, significantly reducing the energy and time resources required for each individual race assessment.
