Automated Weight Adjustment System for Fitness Equipment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional weight training exercises with free weight devices, such as dumbbells and kettlebells, often require manual adjustment of weights, disrupting the training activity and causing pauses, necessitating improved systems for seamless weight adjustment during exercises.
Innovation Solution
A physical fitness assessment system and method that includes an exercise device with a network communication interface, movement tracker, processor, and memory, allowing for automatic weight adjustment through a connected host computer, enabling users to select and adjust weights without interrupting their workout, and providing a physical fitness assessment based on tracked movement data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual weight adjustment is used on free weight devices, then weight can be changed, but training activity is disrupted causing pauses
Solution Approach 1:
The system pre-loads multiple weight configurations into memory before the exercise session begins. The user can select from pre-programmed weight settings or have weights automatically adjusted based on pre-set parameters, eliminating the need for manual weight changes during exercise and preventing training interruptions
Solution Approach 2:
The patent replaces manual mechanical weight adjustment with an automated system that uses electronic controls, sensors, and programmable logic to adjust weights. This substitution of mechanical manual operation with automated electronic control eliminates the time loss associated with manual weight changes while maintaining weight adaptability
2Productivity
If automated weight adjustment system is implemented, then weight can be adjusted without interruption, but device complexity increases
Solution Approach 1:
The system integrates multiple functions into a single automated device including weight adjustment, performance tracking, data storage, and assessment generation. This multi-functionality consolidates what would otherwise require separate devices into one system, managing complexity while maintaining training continuity
Solution Approach 2:
The system automatically adjusts weights and performs assessments without requiring constant user intervention. Once parameters are initially set, the system self-manages weight changes and data collection throughout the exercise session, reducing operational complexity while maintaining productivity
3Measurement precision
If movement tracking and data collection are performed, then physical fitness assessment is enhanced, but measurement and detection difficulty increases
Solution Approach 1:
The system combines multiple sensing functions (movement tracking, weight monitoring, temporal measurement) into an integrated data collection framework. By merging these measurement functions into a single coordinated system rather than separate independent systems, the patent reduces overall detection complexity while maintaining or enhancing measurement precision through cross-validation of data streams
Data Source
AI summary
Physical fitness assessment systems and methods and wellness assessment systems and methods are disclosed. One physical fitness assessment system includes an exercise device and a host computer. The exercise device is configured to track movement of the exercise device by a user, determine a current physical activity data of the user based on, at least, the tracked movement, and transmit the current physical activity data of the user. The host computer is configured to receive from the exercise device the current physical activity data of the user, receive a physical fitness assessment selection to apply to the current physical activity date, compare the current physical activity data against benchmark physical activity data correlated with the exercise device, determine a physical fitness assessment of the user, generate the physical fitness assessment image based on the physical fitness assessment of the user, and present the physical fitness assessment image.
