Engineering Contradiction Analysis
1Ease of operation
If mechanical or hydraulic brake systems are used in RC model vehicles, then braking function is provided, but the system complexity increases and control precision deteriorates due to complex mechanical arrangements
Solution Approach 1:
The patent replaces the traditional mechanical brake system with an electromagnetic brake system. The electromagnetic brake uses an electromagnetic coil to generate magnetic force that acts on a magnetically responsive brake disc, eliminating the need for complex mechanical linkages, cams, and levers. This substitution provides precise electronic control through PWM signals while simplifying the overall mechanical structure.
Solution Approach 2:
The patent employs PWM (Pulse Width Modulation) control to vary the duty cycle of the electromagnetic coil activation, allowing precise adjustment of braking force. By changing the electrical parameter (duty cycle percentage), the system achieves variable braking control without mechanical adjustments, enabling fine-tuned braking performance through electronic parameter modification.
2Force
If mechanical brake systems with multiple components are used, then braking force is generated, but the number of parts increases and maintenance difficulty worsens
Solution Approach 1:
The patent extracts and eliminates unnecessary mechanical components from the brake system. By using an electromagnetic coil to generate braking force directly through magnetic attraction on the brake disc, the system removes intermediate mechanical elements such as brake shoes, pistons, and mechanical linkages, reducing the total part count and simplifying maintenance requirements.
Solution Approach 2:
The electromagnetic brake system requires minimal maintenance as it lacks the wear-prone mechanical components found in traditional brakes. The system is self-regulating through electronic control, and the primary maintenance task involves simple electrical connection checks rather than mechanical adjustment or component replacement.
3Productivity
If conventional brake systems are used, then braking is provided, but the surface area utilization of brake disc deteriorates resulting in reduced braking efficiency
Solution Approach 1:
The patent merges the electromagnetic coil and magnetically responsive brake disc into a unified braking interface where the entire surface of the brake disc can engage with the electromagnetic field. This design allows full surface area utilization compared to conventional brakes that only contact a portion of the disc through pads or shoes, maximizing the effective braking surface and improving overall braking efficiency.
