Electromagnetic Weight Plate Attachment for Real-Time Load Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional weight training equipment requires manual adjustment of weights, which is time-consuming and unable to respond in real-time to the trainee's changing needs, especially during solo training, and existing solutions with torque motors are complex and costly, limited to handlebar-type machines.
Innovation Solution
A weight training auxiliary device with a mechanism that uses electromagnets or permanent electromagnets to adjust the weight load by attaching or detaching weights, controlled by a conduction relay, sensors, and a control device, allowing for real-time adjustments and emergency load release, compatible with various types of training equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual adjustment of weights is used, then the device structure remains simple, but the adjustment process is time-consuming and cannot respond in real-time to trainee needs
Solution Approach 1:
The patent replaces the traditional mechanical weight adjustment system with an electromagnetic system. Electromagnets are integrated into the weight plates, and a conduction relay controls the electromagnetic force to automatically attach or detach weights based on trainee performance data, eliminating manual adjustment and enabling real-time response without complex mechanical mechanisms
Solution Approach 2:
The system automatically adjusts weights based on sensor data from the trainee's performance. The control device receives data from sensors, processes it, and automatically commands the conduction relay to adjust the electromagnetic attachment of weights, enabling the system to serve itself without manual intervention or complex external control mechanisms
2Ease of operation
If torque motor is used for automatic load adjustment, then real-time adjustment is achieved, but the control mechanism becomes complex and costly
Solution Approach 1:
The patent substitutes the mechanical torque motor system with an electromagnetic system. Instead of using a motor to mechanically adjust weights, electromagnets are built into the weight plates themselves, and a simple conduction relay controls the electromagnetic force to attach or detach weights, dramatically simplifying the control mechanism while maintaining automatic real-time adjustment capability
Solution Approach 2:
The electromagnetic system integrated into the weight plates serves multiple functions: it provides the magnetic force to hold weights, enables automatic attachment and detachment, and works with various types of training equipment (stack type machines, weight machines, free weight equipment), making the system universally applicable without requiring complex equipment-specific control mechanisms
3Ease of operation
If air resistance type machine is used for load adjustment, then real-time adjustment is possible, but the training experience lacks the feel of traditional weights
Solution Approach 1:
The patent uses electromagnetic force as an intermediary mechanism. The electromagnets built into the weight plates create a magnetic field that can be controlled to attach or detach weights, providing real-time adjustment while maintaining the physical presence and gravitational pull of actual weight plates, thus preserving the authentic weight training feel that air resistance machines cannot provide
