Solution Overview
Problem
Current bicycle training apparatuses for virtual cycling lack standardized accuracy in power measurement and resistance control, leading to potential unfairness in competitive races, as different models may provide distinct advantages or disadvantages to cyclists.
Innovation Solution
A system comprising a base, a main drive shaft, a motor, a torque sensor, and a rotational speed sensor is used to test the accuracy of bicycle training apparatuses by applying a controlled power input and measuring torque and rotational speed, allowing for comparison with the apparatus's recorded measurements to determine accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If different models of bicycle training apparatuses are used, then cyclists may experience distinct advantages or disadvantages in virtual races, but this leads to a lack of fairness and standardized accuracy in power measurement
Solution Approach 1:
The patent creates a universal testing system that can evaluate multiple types of bicycle training apparatuses (direct-drive trainers, roller trainers, friction trainers) using a standardized protocol. The system applies controlled power input through a motor and measures both actual power output and resistance control across all apparatus types, enabling fair comparison and certification regardless of the specific model or brand used by cyclists in virtual races.
2Adaptability or versatility
If bicycle training apparatuses are designed with varying power measurement and resistance control mechanisms, then manufacturers have design flexibility, but this results in inconsistent measurement accuracy across devices
Solution Approach 1:
The testing system incorporates feedback mechanisms where the motor applies controlled power input and sensors measure both the actual power output and resistance control of the training apparatus. This feedback loop enables identification of measurement discrepancies and resistance control issues, allowing for certification decisions based on objective performance data rather than subjective evaluation of different design approaches.
3Ease of manufacture
If no standardized testing system is implemented, then apparatus manufacturers can innovate freely, but this leads to potential unfairness in competitive virtual cycling races
Solution Approach 1:
The patent implements preliminary action by establishing a standardized testing and certification system before apparatuses are deployed for competitive use. The system pre-evaluates power measurement accuracy and resistance control performance across different models, creating a certified list of approved devices. This preliminary certification ensures that only apparatuses meeting fairness standards are used in virtual races, preventing competitive disadvantages before they can affect competition outcomes.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This system ensures the integrity of virtual cycling competitions by verifying the accuracy of power output measurements across different bicycle training apparatuses, ensuring fairness among athletes by identifying and adjusting for discrepancies in power measurement and resistance control.
Implementation Method 1
coupling the main drive shaft to a hub of the bicycle training apparatus or a hub of a bicycle wheel in contact with the bicycle training apparatus
Implementation Method 2
a torque sensor configured to measure the torque applied to the main drive shaft during rotation thereof
Implementation Method 3
a rotational speed sensor configured to measure the rotational speed of the main drive shaft during rotation thereof
Implementation Method 4
measuring the power input with the bicycle training apparatus and storing the resulting measurements as a second data set, and comparing the first data set and the second data set to determine the accuracy of the bicycle training apparatus

AI summary
Systems and methods for testing the accuracy of a bicycle training apparatus that is configured to measure the power output of a cyclist riding on a bicycle. The system includes a base, a main drive shaft secured to the base, a motor secured to the base and configured to rotate the main drive shaft, torque and rotational speed sensors configured to measure the torque and rotational speed of the main drive shaft during rotation thereof. The bicycle training apparatus may be secured relative to the base and functionally coupled to the main drive shaft. The motor may then be operated to apply a power input to the bicycle training apparatus while measuring the torque and rotational speed of the main drive shaft and the power input with the bicycle training apparatus. The resulting measurements may be compared to determine the accuracy of the bicycle training apparatus.
