Treadmill With Dynamic Belt Speed Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treadmills restrict user form and comfort due to the presence of a frontal rail and lack of side rails, leading to compromised running efficiency and increased injury risk.
Innovation Solution
A treadmill design featuring no frontal rail, with side rails that extend along the longitudinal axis for user safety and control, and dynamic belt speed adjustment based on user position to promote natural running form.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a frontal rail with controls is provided, then user control and safety are improved, but user running form and comfort deteriorate due to restricted positioning
Solution Approach 1:
The patent removes the traditional frontal rail and control panel from the treadmill design. Controls are relocated to the user's handheld device or wireless remote, eliminating the physical obstruction at the front of the treadmill. This allows users to maintain proper running form without being constrained by a frontal rail, while safety features are integrated into the belt system itself through edge detection sensors.
Solution Approach 2:
The patent introduces an intermediary wireless communication system between the user and treadmill controls. Instead of direct physical interaction with frontal controls, users interact with a media player or remote device that wirelessly communicates with the treadmill motor controller. This intermediary layer maintains control functionality while eliminating the restrictive frontal rail structure.
2Ease of operation
If consistent belt speed is maintained, then control simplicity is improved, but user comfort deteriorates due to inability to naturally vary pace
Solution Approach 1:
The patent implements dynamic belt speed adjustment that responds to user movement. The system continuously monitors user position and pace, automatically adjusting belt speed to match natural running variations. This dynamic response allows users to naturally vary their pace without manual intervention, while the system maintains appropriate speed consistency through automated adaptation rather than fixed control settings.
Solution Approach 2:
The patent incorporates feedback mechanisms that detect user position and movement patterns on the belt. Sensors monitor user acceleration, deceleration, and positional changes, feeding this information back to the motor controller which adjusts belt speed accordingly. This closed-loop feedback system enables natural pace variation while maintaining overall control simplicity through automated regulation.
3Reliability
If side rails are added for safety, then user safety is improved, but device complexity increases
Solution Approach 1:
The patent implements safety features selectively at critical locations rather than through comprehensive structural modifications. Edge detection sensors are positioned only at the front and rear edges of the belt where users are most at risk. This localized approach provides effective safety monitoring without adding complex structural elements throughout the entire treadmill assembly.
Solution Approach 2:
The patent replaces traditional mechanical side rails with electronic sensing systems. Instead of physical barriers that would complicate the treadmill structure, wireless or contactless sensors detect user proximity to belt edges and trigger safety responses. This substitution eliminates the need for complex mechanical safety structures while maintaining effective user protection.
4Adaptability or versatility
If media console is positioned at front, then entertainment functionality is improved, but user focus deteriorates due to visual distraction from running metrics
Solution Approach 1:
The patent relocates the media console and control interface from the horizontal plane at the front of the treadmill to a vertical or wireless dimension. Users interact with media players mounted on walls or ceilings at eye level, or use wireless devices, eliminating the need to look down at frontal controls. This dimensional repositioning separates entertainment functionality from the running path, allowing users to maintain proper forward focus while accessing entertainment options.
Data Source
AI summary
An exercise treadmill is disclosed. The treadmill can include one or more sensors to acquire input data. A computer system can trigger one or more actions based on the input data. The input data can correspond to a lengthwise position of the user along a length of a usable surface of the platform and/or a lateral position of the user on the belt. The action(s) can include providing feedback to the user and/or adjusting rotation of the belt and/or a resistance of rotation of the belt. The adjustment can be performed in response to input from a user control requesting the adjustment.
