Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If hydraulic brake systems are used in existing vehicles, then braking force is sufficient, but response time is delayed due to fluid compression and mechanical linkage
Solution Approach 1:
The patent replaces the traditional mechanical/hydraulic brake actuation system with an electrodynamic brake disc that uses electromagnetic fields to generate braking force directly. The brake disc contains conductive segments that interact with magnetic fields from actuators, eliminating the need for hydraulic fluid compression and mechanical linkages, thereby achieving instantaneous brake response.
2Loss of energy
If regenerative braking systems are added to recover kinetic energy, then energy efficiency improves, but system complexity and cost increase
Solution Approach 1:
The electrodynamic brake disc serves multiple functions simultaneously: it provides primary braking force through electromagnetic interaction, acts as a generator to recover kinetic energy during deceleration, and functions as a steering mechanism through differential activation of segments. This multi-functionality eliminates the need for separate regenerative braking systems, reducing overall system complexity.
Solution Approach 2:
The patent merges the braking function and energy recovery function into a single integrated electrodynamic brake disc system. The same conductive segments and magnetic field actuators that provide braking force also generate electrical energy during regenerative braking, combining what were traditionally separate systems into one unified device.
3Reliability
If brake fluid and mechanical linkages are used, then braking force transmission is reliable, but response time is slowed and system maintenance requirements increase
Solution Approach 1:
The patent replaces mechanical linkages and hydraulic fluid transmission with direct electromagnetic field interaction. The electrodynamic brake disc uses magnetic fields to induce currents in conductive segments, generating braking force without any intermediate mechanical or hydraulic components, achieving both reliability and instantaneous response.
4Ease of manufacture
If traditional brake systems are used, then manufacturing and installation are straightforward, but adaptability to new energy vehicles and advanced driving functions is limited
Solution Approach 1:
The electrodynamic brake disc is designed to provide multiple functions including braking, energy recovery, and steering capabilities through differential activation of conductive segments. This universal design makes it adaptable to various vehicle types including new energy vehicles and supports advanced driving functions without requiring separate specialized systems.

AI summary
Disclosed is an electronic brake system. The electronic brake system according to the present embodiment comprises: a first block in which a mechanical part that is mechanically operated and linked with a brake pedal is disposed; a second block in which an electronic part electronically operated and controlled by an electronic control unit is disposed; and a connection line which hydraulically connects the first block and the second block. The first block and the second block can be installed at positions spaced apart from each other in a vehicle, and thus the mountability of the brake system and the degree of freedom in designing the vehicle can be improved.
