Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If coils are extended into the gap of the magnetic body and wound around the magnetic body following the conventional profile limitation, then the magnetic body can be properly assembled with the coils, but the assembly process takes a longer time and causes inconvenience
Solution Approach 1:
The magnetic body is divided into multiple independent modular units (first magnetic body, second magnetic body, etc.), each with its own coils already assembled. This segmentation allows each module to be pre-assembled and tested independently, then quickly installed as complete units, dramatically reducing overall assembly time while maintaining proper coil-magnetic body connection reliability.
Solution Approach 2:
The coils are pre-assembled onto the magnetic body units before final installation. The magnetic bodies are prepared in advance with their coils properly positioned and secured, so that when the modular units are installed in the apparatus, the coil-magnetic body assembly is already complete, eliminating the time-consuming step of extending and winding coils during final assembly.
2Reliability
If the electromagnetic resistance apparatus uses a conventional non-modular structure with coils wound around the magnetic body, then the magnetic circuit can be properly formed, but the assembly process is complex and time-consuming
Solution Approach 1:
The apparatus is divided into modular units where each magnetic body is an independent module with integrated coils. This segmentation simplifies the overall assembly process by reducing the number of steps required to assemble the complete magnetic circuit, while each module maintains its own intact magnetic circuit path through proper design of the modular components.
Solution Approach 2:
The magnetic body and its coils are merged into a single integrated modular unit. By combining these two components that must work together into one pre-assembled module, the invention reduces assembly complexity at the system level while preserving the complete magnetic circuit integrity within each module.
3Force
If the apparatus uses a conventional design with limited damping force, then the structure can be simpler, but the exercising or rehabilitating effect is reduced
Solution Approach 1:
The damping force is enhanced by using multiple modular magnetic body units (first, second, and potentially more) that can be arranged in series or parallel configurations. Each module contributes to the total damping force, allowing the system to achieve higher overall force output while maintaining modular simplicity in each individual unit's design.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The modular design facilitates rapid and cost-effective assembly while providing a larger damping force, significantly enhancing the exercising or rehabilitating effect.
Implementation Method 1
The magnetic body includes a magnetic circuit which having at least two poles, and a plurality of coils wound around each of the poles of the magnetic circuit. Thus, when the coils are energized, the magnetic body produces a magnetic force
Implementation Method 2
a magnetically controlled braking ring secured on a periphery of the inertia wheel, and a magnetic body secured on the fixing frame and aligning with the inertia wheel

AI summary
An electromagnetic resistance apparatus includes a support frame, a metallic conductive plate rotatably mounted on the support frame, and at least one magnetically controlled mechanism mounted on the support frame and aligning with the metallic conductive plate. Thus, the electromagnetic resistance apparatus has a modularized structure so that the electromagnetic resistance apparatus is mounted on a rehabilitation or exercising equipment easily and quickly so as to shorten the time and save the cost of assembly of the electromagnetic resistance apparatus.
