Motor Vehicle Safety Device Indicator System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers are not aware when safety devices in vehicles, such as safety belts and airbags, are activated automatically, lacking assurance about the operational state of these systems before starting the vehicle.
Innovation Solution
Incorporating an indicator system that provides acoustic and optical signals to inform the driver of the activation state of safety devices, distinguishing between idle and operative positions, ensuring the driver is aware of the system's operational status through distinct tones or images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If safety devices are activated automatically without driver input, then the reliability of safety systems is improved, but the driver's awareness of system status deteriorates
Solution Approach 1:
The patent implements feedback mechanisms through acoustic signals (speakers) and optical signals (displays) that provide real-time information to the driver about the activation state of safety devices. When a safety device transitions to an operative position, the system generates audible and visible feedback signals that inform the driver of the system's operational status, thereby resolving the information loss caused by automatic activation.
Solution Approach 2:
The patent introduces intermediary signaling devices (acoustic indicators and optical displays) that mediate between the safety device activation system and the driver. These intermediaries translate the internal system state into perceptible signals for the driver, enabling awareness of automatic safety device activation without requiring direct driver interaction with the safety systems themselves.
2Productivity
If multiple safety devices are operated automatically, then the productivity of safety systems is improved, but the complexity of monitoring system status worsens
Solution Approach 1:
The patent merges the monitoring functions for multiple safety devices into a unified signaling system. Instead of requiring separate monitoring mechanisms for each safety device, the system combines their status information into integrated acoustic and optical signals that can simultaneously convey the operational state of multiple devices, thereby reducing monitoring complexity while maintaining high productivity.
Solution Approach 2:
The patent implements universal signaling components (acoustic speakers and optical displays) that serve multiple safety devices simultaneously. These multi-functional indicators can convey status information for various safety systems through a common interface, eliminating the need for device-specific monitoring mechanisms and simplifying the overall system architecture.

AI summary
A motor vehicle includes a safety device which is changeable between an idle position and an operative position, and an indicator which is rendered operational in at least one of two ways, a first way in which a first acoustic signal is triggered when the safety device departs the idle position, and a second acoustic signal, which differs from the first acoustic signal, is triggered when the safety device has assumed the operative position, a second way in which a first image is optically visualized in a display when the safety device departs the idle position, and a second image is optically visualized in the display when the safety device has assumed the operative position.
