Wireless Vehicle Immobilization Relay for Breath Interlock Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of traditional breath alcohol ignition interlock devices (BAIIDs) is complex, expensive, time-consuming, and often results in permanent vehicle damage due to the need for extensive wiring and modifications to the vehicle's electrical system.
Innovation Solution
A vehicle immobilization system that includes a detection element for measuring the level of intoxicants in a user's breath, a control module that selectively restricts vehicle operation based on the intoxicant level, and a wireless relay that communicates with the control module to control vehicle systems such as the fuel pump, starter motor, or ignition, thereby simplifying installation and reducing damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional BAIID installation methods are used with extensive wiring and electrical system modifications, then the device can reliably detect and prevent intoxicated driving, but the installation becomes complex, expensive, time-consuming, and causes permanent vehicle damage
Solution Approach 1:
The patent replaces the traditional mechanical/electrical wiring system with a wireless communication system. The BAIID device communicates with the vehicle's immobilization system via wireless signals (such as radio frequency communication), eliminating the need for physical wire connections between the breath alcohol detector and the vehicle's electrical system. This substitution maintains the reliability of intoxication detection and prevention while dramatically reducing installation complexity and avoiding permanent vehicle damage.
2Reliability
If traditional BAIID installation methods are used with extensive wiring, then the device can effectively control vehicle systems, but the installation time and cost increase significantly
Solution Approach 1:
The patent replaces time-consuming electrical wiring and connection work with wireless communication technology. The BAIID device establishes communication with the vehicle's control systems through wireless signals, allowing for rapid deployment without the need for technicians to spend hours routing wires through the vehicle's firewall, connecting to multiple electrical components, and performing extensive electrical system modifications. This reduces installation time from potentially days to hours or even minutes, while maintaining full control effectiveness over vehicle systems.
3Reliability
If traditional BAIID installation methods are used with wiring modifications, then the device can securely integrate with vehicle systems, but permanent damage is caused to the vehicle
Solution Approach 1:
The patent replaces invasive electrical wiring and physical modifications with non-contact wireless communication. The BAIID device transmits and receives signals wirelessly with the vehicle's immobilization system, eliminating the need to cut wires, drill holes, or make any permanent modifications to the vehicle's electrical system or body. This approach maintains secure system integration through encrypted wireless communication protocols while completely avoiding harmful physical damage to the vehicle, preserving its resale value and structural integrity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively prevents intoxicated drivers from operating a vehicle while reducing the complexity, cost, and damage associated with traditional BAIID installations, by using a wireless relay and OBDII port connectivity to control vehicle systems.
Implementation Method 1
a driver must use a BAIID device by blowing into an alcohol-sensing element such as a fuel cell that measures the amount of alcohol in the driver's breath
Data Source
AI summary
A vehicle immobilization system includes a detection element operable to detect a level of an intoxicant in a user's breath. A control module is operable to receive a signal from the detection element indicating the level of intoxicant in the user's breath, and to selectively restrict operation of a vehicle based on the level of intoxicant in the user's breath exceeding a threshold. A wireless relay is operable to replace a standard relay in the vehicle, and to wirelessly communicate with the control module such that the control module is operable to control the wireless relay to selectively restrict operation of the vehicle.
