Restraint Simulator Interface for Non-Deploying Impact Tests
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Preventing activation of restraint devices during simulated vehicle impacts requires significant time and manpower, and deviations in preparation procedures can lead to unintended activation.
Innovation Solution
A device is connected between the restraint control module and the main body wire harness, simulating vehicle impacts while preventing restraint device activation, reducing preparation time and manpower through a restraint simulator that includes a first connector to communicate with the RCM and a second connector to communicate with the restraint devices, and a ground wire to connect to the vehicle body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional preparation procedures are used to prevent restraint device activation during simulated vehicle impacts, then restraint device activation can be prevented, but significant time and manpower are required
Solution Approach 1:
The patent introduces a restraint simulator as an intermediary device connected between the restraint control module and the restraint devices. This simulator intercepts and simulates impact signals, preventing actual restraint device activation while maintaining the integrity of the control system. The simulator acts as a mediator that absorbs the preparation complexity, allowing rapid setup without compromising reliability
2Reliability
If traditional preparation procedures are used to prevent restraint device activation during simulated vehicle impacts, then restraint device activation can be prevented, but significant manpower is required
Solution Approach 1:
The restraint simulator is designed to automatically manage the simulation process without requiring manual intervention for complex setup procedures. The device self-configures and self-manages the signal interception and simulation, eliminating the need for extensive manual preparation while ensuring reliable prevention of restraint device activation
3Reliability
If preparation procedures have deviations, then unintended activation of restraint devices can occur, but the device complexity increases
Solution Approach 1:
The restraint simulator serves as a controlled intermediary that standardizes the signal path between the restraint control module and restraint devices. By providing a dedicated, standardized interface, it eliminates variability in preparation procedures while maintaining system simplicity. The simulator encapsulates the complexity within a single device, preventing unintended activation without requiring complex overall system architecture
