Innovation Solution
A fitness display device with a generator, PCB, tension sensor, and rechargeable battery is integrated into a fitness weight device, where the generator acts as a speed sensor and power generator, and the PCB connects these components to display data on a screen and transmit it wirelessly, allowing for real-time tracking and recording of exercise metrics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If traditional weight devices are used, then the structure is simple and easy to manufacture, but the device cannot automatically detect and display weight, distance, and speed data
Solution Approach 1:
The patent combines multiple functions (weight detection, distance measurement, speed detection, data processing, and wireless transmission) into a single integrated display device that attaches to the existing weight machine. The device merges sensors, display units, and communication modules into one compact system, eliminating the need for separate detection and display systems while achieving automatic data collection and presentation.
Solution Approach 2:
The patent introduces an intermediary display device that acts as a mediator between the weight machine and the user. This device includes sensors that detect exercise parameters, a processing unit that calculates data, and a display unit that presents information, thereby bridging the gap between the mechanical weight machine and the user's need for automated feedback without modifying the core machine structure.
2Adaptability or versatility
If traditional weight devices are used, then the device is simple and inexpensive, but it cannot transmit data wirelessly to mobile devices or cloud for fitness tracking
Solution Approach 1:
The patent designs the display device with multi-functionality, incorporating weight detection, distance measurement, speed detection, data processing, wireless transmission, and display functions into a single system. This universal device can attach to various weight machines and provide comprehensive fitness tracking capabilities, making it adaptable to different exercise scenarios and compatible with multiple devices including mobile phones and cloud platforms.
3Measurement precision
If sensors and display components are added to detect and show exercise data, then data tracking capability is improved, but the device structure becomes more complex
Solution Approach 1:
The patent segments the detection functions into separate sensors (weight sensor, distance sensor, speed sensor) that can be independently installed on the weight machine. Each sensor handles a specific measurement task, and the results are processed by a central unit. This segmentation allows for precise measurement of multiple parameters while keeping each component's design simple and modular, facilitating easier manufacturing and maintenance.
