Vehicle Cigarette Lighter with Synchronized Warning Light Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle-mounted cigarette lighters are unable to conveniently or visually indicate the working mode of on-board warning lights, making it difficult for users to control and monitor their status.
Innovation Solution
A multifunctional vehicle-mounted cigarette lighter with a control unit and display unit that synchronizes the working mode of on-board warning lights using a control circuit board and indicator lights, allowing users to visually determine the mode through a series of blinking, flowing, or constant lighting patterns displayed on the cigarette lighter body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a commonly used cigarette lighter only supplies power to the on-board warning light, then the device structure remains simple, but it is unable to reflect the specific working mode of the on-board warning light, making it inconvenient and non-visual for user control
Solution Approach 1:
The patent combines the cigarette lighter function with the warning light control function into a single integrated device. The cigarette lighter body houses both the power supply components for the lighter and the control circuit board for the warning light, allowing users to control the warning light through the lighter interface without requiring separate controls
Solution Approach 2:
The cigarette lighter is transformed into a multi-functional device that not only provides power for lighting cigarettes but also serves as the control interface for the on-board warning light system. The lighter body becomes a universal control unit that can manage multiple warning light modes (emergency, driving, turn signal, etc.) through its indicator lights and button
2Loss of information
If the cigarette lighter only provides power supply without visual feedback, then the device complexity is low, but users cannot visually determine the working mode of the warning light
Solution Approach 1:
The patent implements a feedback mechanism where the control circuit board includes indicator lights that visually display the current working mode of the warning light. When the warning light operates in different modes (emergency blinking, driving constant, turn signal alternating), corresponding indicator lights on the cigarette lighter body light up to provide real-time visual feedback to the user about the system state
Solution Approach 2:
The control circuit board on the cigarette lighter creates a visual copy or representation of the warning light's working modes through its indicator lights. The indicator lights replicate the operational patterns (blinking, constant, alternating) of the actual warning lights, allowing users to see the system status directly on the lighter without needing to observe the external warning lights

AI summary
The present disclosure provides a multifunctional vehicle-mounted cigarette lighter, including a cigarette lighter body, which is configured with a power plug matched with a vehicle cigarette lighter socket, wherein the cigarette lighter body is further provided with a control unit connected to an on-board warning light and a display unit in signal connection to the control unit; the control unit includes a control circuit board for synchronously acquiring the working mode of the on-board warning light, wherein the control circuit board is connected to the on-board warning light through a signal control line; the display unit includes a plurality of indicator lights for synchronously displaying the working mode of the on-board warning light, wherein the plurality of indicator lights are electrically connected to the control circuit board. The present disclosure enables determination of the working mode of the on-board warning light directly though the working mode displayed on the display unit (the plurality of indicator lights) on the cigarette lighter body, which is visual and convenient.
