Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If extensive wiring harnesses are used to connect multiple alert devices, then reliable power and data transmission is achieved, but device complexity and vehicle weight increase significantly
Solution Approach 1:
The system segments the control architecture into a central controller and distributed remote controllers, each managing specific alert devices. This segmentation allows each controller to handle only the signals necessary for its connected devices, reducing the overall wiring complexity while maintaining reliable communication through a modular networked structure.
Solution Approach 2:
The patent introduces a simplified connector as an intermediary component that consolidates multiple electrical connections into a single plug-in interface. This intermediary device manages the complexity of power and data transmission by providing a standardized connection point between the central controller and remote controllers, eliminating the need for extensive individual wiring harnesses.
2Adaptability or versatility
If extensive wiring harnesses are used to connect multiple alert devices, then all devices can be powered and controlled, but vehicle weight increases due to added wiring
Solution Approach 1:
The patent merges power transmission and data communication into a single integrated network. The connector simultaneously carries both power signals and data signals, eliminating the need for separate wiring harnesses for each function. This consolidation reduces the total amount of wiring required while maintaining the ability to support multiple alert devices.
Solution Approach 2:
The connector design provides multi-functionality by serving as both a power source and a communication interface. A single connector implementation supports multiple alert devices through its ability to carry both power and data signals, reducing the overall wiring requirements while maintaining adaptability across different device configurations.
3Reliability
If traditional wiring systems are used for alert devices, then stable operation is achieved, but installation time and complexity increase
Solution Approach 1:
The system performs preliminary configuration through software or firmware programming of the remote controllers before deployment. The controllers are pre-configured with the necessary communication protocols and device identifiers, allowing them to be quickly connected and immediately operational. This preliminary action eliminates the need for complex on-site wiring configurations while maintaining stable operation.
Solution Approach 2:
The remote controllers are designed to automatically configure themselves upon connection to the central controller. The system enables self-service installation through automatic device discovery, authentication, and network integration, eliminating the need for manual wiring configuration while ensuring stable and reliable operation from the moment of connection.
Data Source
AI summary
An control system for use in a vehicle includes at least one functional unit adapted to be mounted in the vehicle, each functional unit having an alert device, connector and a remote controller configured to control a desired state of the respective alert device, and a central controller configured to sense a state of the vehicle and generate a desired state of the functional units based at least partially on the sensed state of the vehicle a functional connection between the central controller and the at least one functional unit.
