Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electro-mechanical brakes face limitations in braking force due to restricted pressurization of disk surfaces by inner and outer pads, leading to inadequate braking torque and response time, and increasing motor capacity is costly and impractical.
Innovation Solution
An electro-mechanical brake design that includes a carrier, caliper, column, moving block, inner pad, outer pad, and upper pad, where the moving block drives the pads to pressurize the disk's inner, outer, and upper surfaces, enhancing braking force through a motor-driven screw mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If the capacity of the motor is increased to enhance braking force, then the braking force and braking torque improve, but the size and cost of the motor increase
Solution Approach 1:
The patent applies dimensionality change by adding a vertical pressurization direction through the upper pad, in addition to the traditional inner and outer surface pressurization. This transforms the braking system from a two-dimensional pad-disk contact to a three-dimensional multi-surface contact, increasing braking force without requiring a larger motor
2Force
If the capacity of the motor is increased to enhance braking force, then the braking force and braking torque improve, but the cost of the system increases
Solution Approach 1:
By adding the upper pad for vertical pressurization, the system achieves enhanced braking force through geometric configuration rather than motor capacity increase, providing a cost-effective solution that avoids expensive high-capacity motors
3Device complexity
If conventional electro-mechanical brake pressurizes only inner and outer surfaces of the disk, then the structure remains simple, but the braking force falls short of expectations
Solution Approach 1:
The patent adds vertical pressurization through the upper pad while maintaining the existing inner and outer pad structure, achieving enhanced braking force with minimal structural modification. The upper pad is integrated into the carrier assembly, keeping the overall structure relatively simple
Solution Approach 2:
The braking system is segmented into multiple independent pad components (inner pad, outer pad, and upper pad) that can be manufactured and assembled separately, allowing for simplified production and maintenance while achieving complex multi-surface pressurization

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 design increases braking force by simultaneously pressurizing multiple surfaces of the disk, improving braking torque and response time without the need for a larger, more expensive motor, resulting in a more efficient and cost-effective braking system.

AI summary
An electro-mechanical brake for increasing a braking force is provided. The electro-mechanical brake for increasing the braking force according to an embodiment of the present invention may include the upper pad together with the inner pad and the outer pad, the inner pad may pressurize the inner side surface of the disk by the movement of the moving block by the rotation of the screw, the outer pad may pressurize the outer side surface of the disk, the upper pad may also pressurize the cylindrical surface of the upper end of the disk, and thus the braking force may be increased since the additional braking force can be further generated by pressurizing the cylindrical surface of the upper end of the disk compared with a case of pressurizing the inner side surface and the outer side surface of the disk.
