Crank Angle Indicator Using Haptic Feedback for Cyclists
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cyclists face challenges in achieving optimal pedaling technique due to the need to focus on visual indicators during training, which can be inconvenient and distracting.
Innovation Solution
A crank angle indicating system that uses a crank angle detector and an indication device to provide aural and haptic cues at predetermined crank angles, allowing cyclists to apply and release force at the appropriate moments without needing to focus on a visual display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a visual display on handlebar or wrist is used to indicate crank angle, then the cyclist can see the indicator, but the cyclist must concentrate attention on the display which is inconvenient during training
Solution Approach 1:
The patent replaces the visual display system with a haptic feedback system using vibration motors integrated into the pedals. This substitution allows information to be transmitted through tactile sensations rather than visual displays, freeing the cyclist's visual attention while maintaining effective communication of crank angle information.
Solution Approach 2:
The patent introduces vibration motors as an intermediary between the crank angle sensor and the cyclist. These motors convert electrical signals into tactile vibrations that are directly transmitted to the cyclist's feet through the pedals, serving as a mediator that delivers information without requiring visual attention.
2Adaptability or versatility
If user configurable settings are implemented for predetermined crank angles, then the system can be optimized for different technique workouts, but the device complexity increases
Solution Approach 1:
The patent implements dynamically adjustable parameters where the predetermined crank angles and vibration characteristics can be configured by users through a programming interface. This allows the system to adapt to different training requirements while maintaining a relatively simple hardware architecture, as the complexity is managed through software configuration rather than hardware complexity.

AI summary
A crank angle indicating system is provided for a pedaling device. The crank angle indicating system may include a crank angle detector configured to detect a crank angle of a crankshaft of a pedaling device, and an indication device configured to output at least one of an aural and a haptic indicator when a predetermined crank angle is reached, allowing a cyclist to time the application or release of force to the pedals accordingly.
