Exercise Bike Handlebar Sensing for Interactive Directional Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pedaled exercise devices lack the ability to effectively integrate directional inputs from users into interactive software and displays, limiting the potential for immersive and engaging workout experiences.
Innovation Solution
The exercise device includes a frame with handlebars and a drivetrain, both equipped with sensors to measure movement and position. These sensors provide directional inputs to a computing device, which communicates with a display to generate visual feedback and simulate various environments, enhancing the user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If sensors are added to handlebars and drivetrain to enable directional inputs, then user interaction capability is improved, but device complexity increases
Solution Approach 1:
The handlebars are designed to serve multiple functions: traditional steering control and directional input detection. The biasing element and sensor system enable the handlebars to detect both intentional directional inputs and unintentional movements, making the same component serve dual purposes without adding separate dedicated input devices.
Solution Approach 2:
The biasing element automatically returns the handlebars to a neutral position after directional input, and the sensor system continuously monitors handlebar position and movement. The system uses the user's natural movements and the handlebars' inherent mechanical properties to generate input data without requiring additional active components or user effort beyond normal exercise motion.
2Ease of operation
If the yoke is made rotatably movable to enable directional input, then ease of operation is improved, but reliability may worsen due to moving parts
Solution Approach 1:
The yoke is designed with rotational movement capability that allows it to dynamically respond to user inputs during exercise. The rotatable connection enables the handlebars to move freely in response to directional inputs while the biasing element provides continuous mechanical feedback, creating a dynamic system that adapts to user movements without rigid constraints.
Solution Approach 2:
The biasing element acts as a mechanical intermediary between the rotatable yoke and the frame. It transmits the rotational movement of the yoke into measurable positional changes while providing smooth mechanical transition and reducing direct stress between moving and fixed components, thereby protecting the rotational joint from excessive wear.
