Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Commercial vehicle trailers lack a simple and efficient operating interface for managing refrigeration and brake control systems, limiting user interaction and data management.
Innovation Solution
A commercial vehicle trailer with a user interface for inputting and displaying operating variables, connected to a control unit via a communication interface, allowing bidirectional data exchange and integration with remote control units, electronic brake control devices, and printers, using a CAN bus for reliable data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate control devices are used for refrigeration and brake systems, then each system can be controlled independently, but the number of devices increases and operational complexity increases
Solution Approach 1:
The patent combines the control of refrigeration and brake systems into a single integrated control unit. The control unit receives sensor inputs from both systems and processes control commands centrally, reducing the number of separate control devices while maintaining independent controllability of each subsystem through unified interfaces
2Adaptability or versatility
If multiple separate interfaces are provided for different control systems, then each system can be optimized for its specific function, but the ease of operation decreases due to multiple interfaces
Solution Approach 1:
The patent implements a universal control interface that can handle both refrigeration and brake system controls. The interface is designed to be multi-functional, accepting various input types (manual inputs, sensor data) and controlling different subsystems through a single unified interaction point, thereby improving ease of operation while maintaining system-specific optimization
3Reliability
If data from multiple control systems is managed separately, then data integrity for each system is maintained, but data management efficiency decreases
Solution Approach 1:
The patent merges data management for refrigeration and brake systems into a single centralized data processing unit. The control unit collects, processes, and manages data from both systems in one location, maintaining data integrity through standardized processing protocols while significantly improving data management efficiency by eliminating redundant separate management structures

AI summary
A commercial vehicle trailer, in particular a refrigerated semi-trailer or a refrigerated trailer, is described, comprising a cooling unit for cooling a cargo space, which has a user interface for inputting and displaying at least one operating parameter, and a control unit arranged outside an electronic brake control device, which is coupled to at least one remote control unit, characterized in that the user interface and the control unit can be connected to each other via a communication interface, wherein data output from the control unit is made via the user interface of the cooling unit.
