Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If multiple motors, gears, and bolt screws are used to press brake pads on both sides, then braking force is improved, but device complexity and cost increase
Solution Approach 1:
The brake device is divided into two independent pressing mechanisms: a hydraulic pressing mechanism for the first brake pad and an electromechanical pressing mechanism for the second brake pad. This segmentation allows each side to use optimized technology (hydraulic for simplicity, electromechanical for control precision) rather than forcing a uniform complex system on both sides, thereby reducing overall device complexity while maintaining sufficient braking force.
Solution Approach 2:
The patent combines hydraulic and electromechanical pressing mechanisms into a single brake device. The hydraulic mechanism handles the first brake pad with simple fluid pressure transmission, while the electromechanical mechanism handles the second brake pad with motor-driven precision control. This merging of different pressing principles allows the system to achieve effective braking force without requiring complex mechanisms on both sides.
2Force
If multiple motors, gears, and bolt screws are used to press brake pads on both sides, then braking force is improved, but manufacturing cost increases
Solution Approach 1:
The brake device is divided into two independent pressing mechanisms: a hydraulic pressing mechanism for the first brake pad and an electromechanical pressing mechanism for the second brake pad. This segmentation allows each side to use optimized technology (hydraulic for simplicity, electromechanical for control precision) rather than forcing a uniform complex system on both sides, thereby reducing overall device complexity while maintaining sufficient braking force.
Solution Approach 2:
The patent employs a hydraulic pressing mechanism using a master cylinder and brake fluid to transmit pressing force to the first brake pad. This hydraulic system provides a cost-effective and simple method to generate sufficient braking force without requiring multiple motors, gears, and bolt screws, thereby reducing manufacturing cost while maintaining effective braking capability.
3Device complexity
If a single motor with reduction gear and bolt screw is used, then device complexity is reduced, but operational deviation occurs
Solution Approach 1:
The brake device is divided into two independent pressing mechanisms: a hydraulic pressing mechanism for the first brake pad and an electromechanical pressing mechanism for the second brake pad. This segmentation allows each side to use optimized technology (hydraulic for simplicity, electromechanical for control precision) rather than forcing a uniform complex system on both sides, thereby reducing overall device complexity while maintaining sufficient braking force.
Solution Approach 2:
The patent introduces a hydraulic pressing mechanism as an intermediary system to handle the first brake pad, using brake fluid and a master cylinder to transmit pressing force. This hydraulic intermediary provides stable and reliable force transmission without the operational deviations associated with electromechanical systems, thereby improving overall operational stability while keeping device complexity low.

Function Achieved in This Case
The solution enables stable braking without operational deviations, reduces component size and weight, and allows for a more compact design, thereby freeing up space for other components like the electronic control unit.
Implementation Method 1
This force generates a pressure in the brake fluid in the master cylinder. Based on the Pascal's principle, this pressure is transmitted via a brake pipe to each wheel cylinder and back to a caliper piston.
Implementation Method 2
a spring member for elastically supporting upper portions of two pad plates to prevent vibration of the pad plate and to ensure a smooth return operation
Implementation Method 3
a brake device located inwardly of a rotating wheel and applying a great pressure to a disk-shaped brake disk rotating together with the wheel from both sides using brake pads
