Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing trailer connectivity solutions face challenges such as structural modifications, durability issues, and compatibility with different trailer types, which hinder efficient communication between trailers and tractor electrical systems.
Innovation Solution
A gateway device is introduced, featuring a processing circuit housed under the trailer, connected via a single cable to an electrical socket at the front of the trailer. This device supports various communication protocols like Ethernet, PLC, and CAN, enabling bi-directional communication without ABS module intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a gateway device is installed to enable bi-directional communication between trailer and tractor electrical systems, then connectivity and operational efficiency are improved, but device complexity and installation requirements increase
Solution Approach 1:
The gateway device is designed to support multiple communication protocols (CAN, Ethernet, WiFi, Bluetooth) and can interface with various trailer electrical systems and telematics devices simultaneously. This multi-functionality allows a single device to replace what would otherwise require multiple separate communication interfaces, resolving the contradiction by providing universal adaptability without proportionally increasing complexity.
Solution Approach 2:
The gateway device acts as an intermediary between the trailer's electrical system and various communication networks. It translates and mediates communication between different protocols and systems, enabling bi-directional data flow without requiring direct integration between all components. This intermediary approach simplifies the overall system architecture while maintaining high connectivity capability.
2Ease of manufacture
If the processing circuit is housed under the trailer and connected via a single cable through the kingpin plate, then ease of installation and retrofitting are improved, but reliability of electrical connection may worsen due to cable routing through moving parts
Solution Approach 1:
The electrical connection system is designed to accommodate the dynamic movement between the trailer and tractor during coupling and uncoupling operations. The single cable routing through the kingpin plate is engineered with sufficient slack and proper tensioning to handle the range of motion without damage, transforming a potentially rigid connection into a dynamic one that maintains reliability despite movement.
Solution Approach 2:
The cable routing system includes protective elements and sufficient cable length to cushion against potential damage during installation and operation. The excess cable length acts as a buffer that prevents tension and stress concentration at critical connection points during trailer movement, thereby maintaining connection reliability while enabling easy installation.
3Productivity
If direct communication with vehicle systems is enabled without ABS module intervention, then communication speed and efficiency are improved, but compatibility with different vehicle systems may worsen
Solution Approach 1:
The gateway device can dynamically change communication parameters such as protocol type, data rate, and signal format based on the detected vehicle system. This parameter adaptability allows direct communication without ABS intervention while maintaining compatibility across different vehicle platforms, as the device adjusts its communication characteristics to match the target system.
Solution Approach 2:
The communication functionality is segmented into protocol-specific modules within the gateway device. Each module handles a specific communication protocol or interface type, allowing the system to select and activate only the required segment for direct communication. This modular segmentation enables high-speed direct communication while maintaining broad compatibility through selective protocol activation.
