Weight Training System with Biophysical Sensors for Posture Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In weight training, individuals lack effective means to detect inappropriate postures or equipment operations, leading to uncoordinated movements and increased risk of sports injuries due to inadequate feedback.
Innovation Solution
A weight training system integrating a load sensor, activity sensor, and biophysical quantity sensor, coupled with a computing device, to detect and calculate operation power and energy power, providing real-time feedback to adjust exercises and prevent injuries.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If on-site coaching is used to detect inappropriate postures, then detection capability is improved, but device complexity and operational requirements increase
Solution Approach 1:
The weight training apparatus enables users to self-monitor their exercise parameters through integrated sensors that automatically track weight, repetitions, and biomechanical data, eliminating the need for external coaching intervention for basic monitoring functions
Solution Approach 2:
Manual coaching observation is replaced with automated sensor systems including load cells, encoders, and biomechanical sensors that objectively measure and analyze user posture and movement patterns without human intervention
2Measurement precision
If multiple sensors and computing devices are integrated, then measurement precision and feedback capability are improved, but device complexity increases
Solution Approach 1:
Multiple sensing functions (weight measurement, motion tracking, biomechanical analysis) are merged into an integrated control system within the apparatus, where sensors, processors, and feedback mechanisms work as a unified whole rather than separate components
Solution Approach 2:
The control system performs multiple functions simultaneously including weight measurement, repetition counting, posture analysis, and real-time feedback provision, allowing a single integrated system to replace what would otherwise require multiple separate devices
Data Source
AI summary
A weight training method, a weight training apparatus and a weight training system are provided. In the method, a weight of a load of a user operating the weight training apparatus is detected by a load sensor, a motion of the load is detected by an activity sensor, and thereby an operation power of the weight training apparatus is calculated. A force applied by the muscle portion when the user operates the weight training apparatus is detected by at least one biophysical quantity sensor disposed on at least one muscle portion of the user and used to calculate an energy power consumed by the user. An exercise efficiency value of the user is calculated by using the energy power and the operation power, and the user is prompted to adjust an operation performed on the weight training apparatus when the exercise efficiency value drops beyond a preset ratio.
