Force-Sensing Exercise Handle With Visual and Audio Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable exercise devices struggle to accurately measure and provide clear feedback on the forces exerted during training, as digital displays are often obscured by the user's body or require separate setup, complicating the exercise form.
Innovation Solution
A portable device with a force indicator integrated into the handle, providing visual and audio feedback, and optionally connected to a CPU for data recording and analysis, allowing users to accurately monitor and adjust their training based on real-time force feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a digital display is integrated into the handle of a portable exercise device, then force measurement capability is improved, but the display may be obscured by the user's body during exercise
Solution Approach 1:
The patent transitions from a 2D display surface to a 3D volumetric display using acoustic waves. The force feedback is conveyed through haptic actuators that create tactile sensations and audible clicks, allowing the user to perceive force measurements through multiple sensory dimensions (touch and hearing) rather than relying solely on visual display.
Solution Approach 2:
The patent implements real-time force feedback through haptic actuators that provide tactile resistance and audible click sensations corresponding to force thresholds. This closed-loop feedback system allows users to感知 and adjust their applied force dynamically during exercise, compensating for the lack of visual display information.
2Measurement precision
If force measurement devices are added to portable exercise equipment, then training monitoring capability is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple functions into the handle assembly: force sensing elements are integrated directly into the handle structure, which also serves as the user interface through haptic actuators and audio feedback. This consolidation eliminates separate display devices and wiring, reducing overall system complexity while maintaining monitoring capabilities.
Solution Approach 2:
The handle itself serves as both the measurement sensor and the feedback interface. The force sensing elements detect user input, and the same handle structure delivers haptic and audio feedback, making the device self-sufficient and eliminating the need for external monitors or complex control systems.
3Measurement precision
If visual feedback is provided during exercise, then force monitoring accuracy is improved, but exercise form may be compromised due to obscured display
Solution Approach 1:
The patent provides force feedback through tactile and audible channels that do not require visual attention. Haptic actuators create resistance sensations and click sounds that inform users of force thresholds and proper technique, allowing them to maintain correct exercise form while receiving real-time force monitoring feedback through touch and hearing.
