Cardiovascular Exercise Device Pacing Bar Visual Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cardiovascular exercise methods, such as the multi-stage fitness test, face challenges in providing real-time pacing information, are environment-dependent, and lack motivation due to the absence of a clear finish line, making it difficult for users to maintain the required pace and measure fitness effectively.
Innovation Solution
A cardiovascular exercise device with a pacing bar that provides continuous visual pacing information, allowing users to track their speed and stay on pace, and can be used in various environments, including noisy gyms, with adjustable track distances and rest period indicators, and integrated with mobile devices for fitness tracking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional beep-based pacing system is used, then the test can be administered, but users cannot clearly understand their real-time pacing status and motivation is reduced due to lack of clear finish line indication
Solution Approach 1:
The patent implements a pacing bar that provides continuous visual feedback to users about their real-time pacing status. The bar moves between start and finish line representations, showing users whether they are ahead or behind the required pace. This continuous feedback mechanism resolves the information loss problem by making pacing status immediately visible and understandable, thereby improving user comprehension and motivation.
Solution Approach 2:
The pacing bar acts as an intermediary visual element between the user and the timing system. Instead of directly interpreting beep timings, users interact with the visual pacing bar that mediates the information, showing their position relative to the required pace. This intermediary provides intuitive visual cues that enhance user understanding without requiring them to process complex timing data.
2Adaptability or versatility
If audio beep system is used for pacing, then the test can be conducted, but it becomes environment-dependent and cannot be effectively used in noisy environments like gyms
Solution Approach 1:
The patent replaces the acoustic-based pacing system with an optical/visual system. Instead of relying on audio beeps that are susceptible to noise interference, the invention uses a visual pacing bar displayed on a screen or LED indicators. This substitution eliminates the harmful effect of environmental noise, allowing the test to be conducted effectively in noisy environments like gyms while maintaining pacing accuracy.
Solution Approach 2:
The patent changes the signaling parameter from acoustic (audio beeps) to optical (visual display). By transforming the pacing information from sound waves to light-based visual cues, the system becomes immune to noise interference. The visual pacing bar can be clearly perceived regardless of ambient sound levels, thereby resolving the environmental adaptability issue.
3Device complexity
If only beep timing is provided without visual feedback, then the system is simple, but users lack real-time pacing awareness and cannot effectively maintain required pace
Solution Approach 1:
The patent employs color changes in the pacing bar to communicate pacing status. The bar may change colors or intensity to indicate whether users are ahead, on pace, or behind the required speed. This visual encoding provides precise pacing information without requiring complex interfaces, maintaining system simplicity while significantly improving pacing accuracy and user awareness.

AI summary
A cardiovascular exercise device is provided, The cardiovascular exercise device is for use to administer an exercise program comprising shuttle runs. The cardiovascular exercise device comprises: a tower placeable at a first location; a user input associated with the tower; a pacing bar arranged to display a target pace of a user for a shuttle run of a track distance from the first location; and a processor configured to operate an exercise program. The administration of the exercise program comprises the steps of: receiving a signal from the user input; defining a repetition as the time between subsequent signals from the user input; and indicating pacing information to the user based upon this signal.
