Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional exercise devices lack real-time feedback and display capabilities, providing unsatisfactory sensory feedback to exercisers during their workouts.
Innovation Solution
An improved exercise bar equipped with a sensor to measure strain and a processor to communicate exercise information wirelessly, allowing for real-time feedback and data display on a remote client device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional exercise devices are used, then the device structure remains simple, but real-time feedback and sensory feedback capabilities are lacking
Solution Approach 1:
The sensor and processor are nested within the handle tube structure. The sensor is disposed on the center shaft which is fitted through the longitudinal interior bore of the handle tube, and the processor is disposed in the interior of the exercise bar, creating a compact integrated system that adds feedback functionality without significantly increasing external dimensions
Solution Approach 2:
The sensor acts as an intermediary element that converts mechanical strain during exercise into electrical signals that can be processed and transmitted. This intermediary conversion enables the transition from mechanical exercise data to actionable feedback information without requiring complex direct measurement systems
2Measurement precision
If no sensor is added to the exercise bar, then the device remains simple, but exercise information cannot be captured or measured
Solution Approach 1:
The sensor is disposed on the center shaft which naturally experiences strain during exercise performance. The sensor leverages the self-service principle by utilizing the inherent mechanical stress and deformation of the center shaft during use to generate measurement data without requiring external measurement apparatus
Solution Approach 2:
The patent replaces complex mechanical strain measurement systems with an electronic sensor that converts mechanical strain into electrical signals. This substitution simplifies the measurement process while improving precision, as the sensor can accurately detect and transmit strain data without requiring complex mechanical linkages or gauges
