Ignition Relay Cutoff Using Horn and Lamps for Vehicle Theft Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anti-theft systems for vehicles are ineffective as they require conscious effort from unauthorized operators to be disabled, and can be easily bypassed by shorting ignition wires, allowing unauthorized starting of the vehicle.
Innovation Solution
A relay control unit connected in parallel with the ignition lock module and wiring harnessing module, which activates a relay unit to disconnect the ignition system when unauthorized access is detected, using existing vehicle loads like the horn and turn signal lamps as an alarm system to prevent starting and alert the owner.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a relay control unit is added to automatically detect and disable unauthorized access, then vehicle security is improved, but device complexity increases
Solution Approach 1:
The relay control unit automatically detects unauthorized access attempts and triggers the alarm system without requiring manual intervention from the vehicle owner. The system monitors itself and responds autonomously to security threats, improving reliability while maintaining manageable complexity through automation of routine security functions.
Solution Approach 2:
The relay control unit acts as an intermediary between the ignition system and the alarm system. It monitors the electrical connections and mediates between the ignition lock module/wiring harnessing module and the relay unit, enabling automatic security responses without directly complicating the core ignition or alarm systems.
2Device complexity
If existing vehicle loads are utilized as alarm system, then cost and installation space are reduced, but alarm functionality is limited to existing components
Solution Approach 1:
The horn and turn signal lamps, which are existing vehicle components with primary functions for communication and safety, are repurposed to also serve as alarm system components. This multi-functionality reduces the need for separate dedicated alarm components, lowering installation complexity and cost while providing adequate security functionality through familiar vehicle elements.

AI summary
The present subject matter provides an auto diagnostic security alarm system in a saddle type vehicle (100). The present subject matter specifically provides a system which prevent an unauthorized user access of the vehicle. It further provides an ignition lock module (201) and a wiring harness module (201A) which are electrically connected to each other by a pair of connectors (202,203). The present subject matter utilizes one or more existing loads already provided in the vehicle such as horn (206) and a turn signal lamp (226) and utilizing the same for the alert and indication system when any unauthorized person tried to access the vehicle. The present subject matter reduces the additional cost and installation space by utilizing the existing parts of the vehicle.
