Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern vehicles face challenges in integrating aftermarket audio equipment due to inconsistent battery voltage and timing issues during stop-start events, leading to system pops and shutdowns, as existing solutions like factory switched-ignition wires, manual switches, and digital bus interfaces fail to provide reliable activation/deactivation timing for aftermarket amplifiers.
Innovation Solution
A device that monitors battery voltage changes to detect engine running status and provides adjustable turn-on and turn-off delays for aftermarket components, allowing proper integration with factory systems by generating regulated voltage outputs and controlling battery isolation, preventing shutdowns and battery drain during stop-start events.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If factory switched-ignition wires or manual switches are used to control aftermarket amplifiers, then activation/deactivation can be achieved, but system pops and shutdowns occur during stop-start events due to inconsistent battery voltage and timing issues
Solution Approach 1:
The device performs preliminary actions by providing adjustable turn-on delays to ensure aftermarket components are activated in the correct sequence before the engine starts, and turn-off delays to ensure they remain active during stop-start events. This preliminary timing control prevents system pops and shutdowns by ensuring proper voltage stability before component activation.
Solution Approach 2:
The device changes the timing parameters of voltage output by providing adjustable turn-on and turn-off delays. This allows customization of the activation sequence to match specific component requirements, ensuring reliable operation during stop-start events by maintaining voltage above threshold levels for the necessary duration.
2Ease of operation
If existing solutions are used without adjustable delays, then installation is simpler, but battery drain occurs during stop-start events and components shut down unexpectedly
Solution Approach 1:
The device provides self-service through programmable delay settings that automatically adjust the timing of voltage output based on engine status detection. The adjustable turn-on and turn-off delays enable the system to self-regulate power delivery, preventing battery drain and ensuring continuous operation during stop-start events without requiring manual intervention.
Solution Approach 2:
The device introduces dynamic control by allowing different delay settings for turn-on and turn-off operations. This dynamic timing adjustment enables the system to adapt to varying operational conditions, maintaining component stability during stop-start events while preserving installation simplicity through a unified device interface.
3Speed
If no turn-on delay is provided, then components activate immediately, but timing conflicts occur with factory systems causing system pops
Solution Approach 1:
The device applies preliminary action by introducing configurable turn-on delays that sequence the activation of aftermarket components to occur after factory systems have stabilized. This prevents timing conflicts and system pops by ensuring that voltage is delivered at the appropriate moment, maintaining both activation speed and system compatibility.
Solution Approach 2:
The device uses feedback from engine status detection to dynamically adjust the turn-on timing. By monitoring when the engine actually starts and using this information to trigger the delayed voltage output, the system eliminates timing conflicts with factory electronics while maintaining rapid activation once the delay period elapses.
4Duration of action of stationary object
If battery isolation is not controlled, then continuous power is supplied, but battery drain occurs during parked periods in stop-start vehicles
Solution Approach 1:
The device implements periodic action by using the adjustable turn-off delay to periodically disconnect power to aftermarket components after the engine has been running for a specified duration or when parked for a set time. This periodic power management maintains component operation during driving while preventing battery drain during parked periods, optimizing both duration of action and energy conservation.

AI summary
A multiple wired input/output device provides generated battery or regulated voltage outputs with adjustable turn-on and turn-off timing with sequence priority to engine running status. Separate aftermarket audio components, or a combination of aftermarket audio and non-audio related components are activated and deactivated in appropriate order for a variety of installation applications. One or more switched battery voltage inputs override the sequence priority of generated battery or regulated voltage output(s) in relation to engine running status, order or duration.
