Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the brake device and magnetic control resistance device are arranged independently, then each device can function separately, but the structure becomes complex and reliability decreases
Solution Approach 1:
The patent combines the brake device and magnetic control resistance device into a single integrated module. The brake driver integrates both the brake mechanism (with brake pad and brake shoe) and the magnetic control resistance mechanism (with magnet and aluminum disc) into one unified structure, eliminating the need for separate independent arrangements and reducing overall structural complexity while improving reliability through unified control.
2Device complexity
If the brake device and magnetic control resistance device are arranged independently, then each device can be controlled separately, but the control system becomes more complex and cost increases
Solution Approach 1:
The brake driver is designed as a multi-functional component that simultaneously provides both braking control and magnetic resistance control. The single driver mechanism can switch between braking mode (contacting the flywheel rim) and magnetic resistance mode (positioning the magnet relative to the aluminum disc), eliminating the need for separate control systems and reducing manufacturing costs through component consolidation.
3Force
If the flywheel has large weight for inertial force, then the load adjustment function is improved, but the risk of user injury from uncontrolled rotation increases
Solution Approach 1:
The integrated brake device is designed to preemptively counteract the inertial force of the heavy flywheel. The brake mechanism can be rapidly activated to apply frictional force against the flywheel rim, creating a counteracting torque that opposes the flywheel's rotational momentum. This preliminary anti-action capability ensures that even with large inertial force for load adjustment, the system can quickly neutralize any uncontrolled rotation to prevent user injury.
