Solution Overview
Problem
Existing emergency signaling devices for vehicles are not flexible and require complex installation and maintenance, making them costly and difficult to retrofit across different vehicle types.
Innovation Solution
A device with a plug-in design that uses sensor devices to detect collision data and transmit emergency messages via wireless or wired communication, utilizing the vehicle's power supply and allowing easy installation and removal, with options for wireless near-field or far-field data communication to external devices like mobile phones.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If permanently installed emergency signaling devices are used in vehicles, then the emergency signaling function is reliable, but the installation complexity and cost increase
Solution Approach 1:
The emergency signaling system is divided into separate functional modules: a control unit with evaluation logic, sensor devices for collision detection, and a communication unit. These modules can be independently installed or integrated, allowing flexible deployment from simple plug-and-play solutions to fully integrated systems, thereby reducing installation complexity while maintaining reliability
Solution Approach 2:
The control unit is designed to perform multiple functions: evaluating sensor signals for collision detection, determining emergency situations based on multiple criteria, and controlling the communication unit for various data transmission methods. This multi-functionality reduces the overall system complexity by consolidating functions into a single controllable module
2Reliability
If permanently installed emergency signaling devices are used in vehicles, then the emergency signaling function is reliable, but the retrofit cost increases
Solution Approach 1:
The system allows segmentation of installation costs by offering modular components that can be installed independently. The control unit can be installed separately from sensor devices and communication units, enabling customers to choose budget-friendly configurations (e.g., using existing sensors or communication modules) while maintaining core emergency signaling functionality
Solution Approach 2:
The system is designed to utilize existing vehicle components where possible, such as the vehicle's power supply system, existing sensors, or built-in communication modules. This self-service approach reduces retrofit costs by eliminating the need for dedicated separate systems for each function
3Reliability
If complex installation procedures are used for emergency signaling devices, then the system integration is thorough, but the ease of operation decreases
Solution Approach 1:
The control unit is designed as a self-contained module with integrated evaluation logic that automatically processes sensor signals and determines emergency situations. This segmentation eliminates the need for complex manual configuration and system integration, as the module simply needs to be connected to power and sensors, thereby improving ease of operation while maintaining thorough system integration
Solution Approach 2:
The control unit continuously evaluates sensor signals and automatically determines when an emergency situation occurs based on predefined criteria. This automated feedback mechanism eliminates the need for manual system calibration or configuration, allowing thorough system integration to be achieved through automatic adaptation rather than complex installation procedures
