Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional trailer vehicles with electronic brake systems face issues with intermittent voltage supply to the brake control device, which is typically only available during braking operations, and lack a reliable mechanism for high-speed data transmission to the tractor vehicle.
Innovation Solution
An electronic brake system for trailer vehicles that includes a first electrical interface for connecting to a tractor vehicle with a first voltage supply and a high-speed data interface with a second voltage supply, ensuring continuous power to the brake control device and enabling data transmission rates up to 1 Gbit/s.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the brake control device is supplied with voltage only during braking operations via brake lights, then the voltage supply is simplified, but the reliability of continuous operation is worsened
Solution Approach 1:
The patent applies multi-functionality by enabling the high-speed data interface to serve dual purposes: transmitting data between the trailer and tractor vehicle, and simultaneously providing voltage supply to the brake control device. This eliminates the need for a dedicated voltage supply system while ensuring continuous power availability, thus resolving the contradiction between simplified design and reliable continuous operation.
2Speed
If a high-speed data interface is added for data transmission up to 1 Gbit/s, then the data transmission capability is improved, but the device complexity is worsened
Solution Approach 1:
The high-speed data interface is designed to perform multiple functions simultaneously: it transmits data at rates up to 1 Gbit/s and also serves as a voltage supply pathway for the brake control device. By integrating these functions into a single interface, the patent avoids adding separate dedicated systems, thereby improving data transmission capability while minimizing the increase in overall device complexity.
3Reliability
If the brake control device is connected to multiple voltage supplies, then the fail-safe capability is improved, but the device complexity is worsened
Solution Approach 1:
The patent implements redundancy by connecting the brake control device to multiple voltage supply pathways: the traditional brake light voltage supply and the new high-speed data interface voltage supply. The control device can switch between these supplies or use them in parallel, ensuring continuous operation even if one supply fails. This multi-functionality approach provides fail-safe capability without requiring entirely separate dedicated backup systems.
