Mine Safe Level Sensor Layout for Passenger Position Warning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicles operating in mine-infested areas face safety risks as passengers can be injured if a mine explodes beneath the vehicle, with existing solutions requiring modifications to the vehicle body to mitigate this risk.
Innovation Solution
A mine safety arrangement using a sensor system that provides signals at a predetermined mine safe level within the vehicle, alerting passengers if they cross this level, thereby ensuring safety without adapting the vehicle body, utilizing light beams or laser beams for easy detection and providing visual, auditory, or tactile warnings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an inner mine floor is added to protect passengers, then passenger safety is improved, but the inner space of the vehicle is reduced
Solution Approach 1:
The patent replaces the mechanical structural solution (inner mine floor) with a sensor-based detection system. Sensors detect the position of passengers and generate warnings when they are in dangerous positions, eliminating the need for physical space-consuming structural modifications while maintaining safety.
Solution Approach 2:
The patent introduces an intermediary warning system between the hazard (mine explosion) and the passenger. Instead of directly protecting passengers with physical barriers, the system uses sensors and warning signals as intermediaries to alert passengers to adjust their positions, thereby avoiding injury without reducing inner space.
2Reliability
If the vehicle body is adapted to improve mine safety, then passenger protection is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent replaces complex mechanical adaptations of the vehicle body with a simpler sensor-based detection system. The sensors monitor passenger positions and provide warnings, avoiding the need for complex structural modifications to the vehicle body while achieving the same safety objective.
Solution Approach 2:
The system enables passengers to self-protect by providing them with real-time information about their safety status through warnings. Passengers autonomously adjust their positions based on the warnings, eliminating the need for complex automated protection systems or vehicle body adaptations.
3Measurement precision
If sensor signals are provided at mine safe level, then detection precision is improved, but the device complexity increases
Solution Approach 1:
The patent applies sensors specifically at the critical mine safe level threshold rather than throughout the entire vehicle. This localized placement provides precise detection of passengers crossing the safety threshold while minimizing the overall number of sensors and system complexity.

AI summary
The present invention relates to a mine safety arrangement and a method for facilitating mine safe operation of a vehicle. Said vehicle comprises a vehicle body and a vehicle body connected ground engaging arrangement for moving the vehicle. Said vehicle body comprises a bottom portion and an inner space having a floor portion associated with said bottom portion. Said inner space comprises a mine safe level at a predetermined distance from said floor portion. Persons housed in said inner space having all body portions at or above said mine safe level are expected to be safe should the vehicle be subjected to a mine. Said mine safety arrangement comprises a sensor arrangement configured to provide signals at said mine safe level so that body portions crossing said mine safe level are detected by means of said signals for alerting persons that body portions crossed said mine safe level.
