Treadmill Console Sensors for Lateral Drift Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of treadmills often drift laterally, risking injury from falling off the machine, as existing technologies lack effective mechanisms to alert users of their position relative to the treadmill's edges during exercise.
Innovation Solution
A treadmill system equipped with sensors on the console that detect the user's lateral position and provide alerts, such as visual or auditory cues, to remind users to stay centered, reducing the risk of falling by indicating proximity to the edge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If no lateral position monitoring system is installed, then the treadmill structure remains simple and cost-effective, but users risk falling off the machine due to lateral drift
Solution Approach 1:
The patent implements a feedback mechanism where sensors continuously monitor the user's lateral position on the tread belt and provide real-time alerts when the user approaches the lateral edge. This feedback loop enables the system to detect potential safety issues and warn users before they fall off, directly addressing the reliability concern while maintaining reasonable system complexity through targeted monitoring rather than comprehensive control.
2Reliability
If sensors and alert systems are added to monitor user position, then user safety is improved, but the device complexity and cost increase
Solution Approach 1:
The system employs self-service principles by using the treadmill's existing console and display infrastructure to present safety alerts to users. Rather than requiring separate dedicated alerting devices, the system leverages the already-present user interface components, thereby improving safety while minimizing the increase in device complexity and component count.
3Reliability
If comprehensive position monitoring is implemented, then safety is enhanced, but the ease of operation is reduced due to additional alerts and notifications
Solution Approach 1:
The patent applies local quality by providing targeted, location-specific alerts only when the user approaches the lateral edge of the tread belt. Rather than implementing continuous or comprehensive monitoring that would constantly notify the user, the system activates alerts only in the specific condition where safety is at risk, thereby enhancing safety monitoring while preserving user convenience during normal operation.
Data Source
AI summary
A treadmill includes sensors on a console at the front of the treadmill. The sensors sense the lateral position of a user relative to the edge of the exercise deck and/or the exercise belt. If the user is close to the edge of the exercise deck, then an alert is displayed on the console.
