Vehicle Warning Lamp Separate Power Supply Failure Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicle systems, separate power supplies for warning lamps and meters make it difficult for riders to recognize power supply failures, as the meter remains functional even when warning lamps are de-energized, and grounding issues are similarly hard to detect without integrated systems.
Innovation Solution
A warning lamp device with separate power and grounding terminals connected to the meter, allowing the meter to remain powered and display failures even if warning lamps lose power or grounding, ensuring riders can quickly identify issues through the meter's indications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the warning lamp is disposed separately from the meter with separate power supplies, then layout freedom and design versatility are improved, but the rider's ability to recognize power supply failures is worsened
Solution Approach 1:
The patent merges the power supply system by having the meter share the same power supply circuit as the warning lamp. The power supply terminal connects to both the meter and warning lamp through common wiring, so that when the warning lamp fails due to power supply issues, the meter also fails to operate, providing a reliable failure indicator to the rider while maintaining separate physical locations for layout freedom.
2Adaptability or versatility
If the warning lamp is disposed separately from the meter with separate power supplies, then design needs are improved, but the rider's ability to recognize grounding failures is worsened
Solution Approach 1:
The patent merges the grounding system by having the meter and warning lamp share the same ground terminal. The ground terminal connects to both components through common grounding wiring, so that grounding failures affect both the meter and warning lamp simultaneously, enabling the rider to recognize grounding issues through meter malfunction while maintaining separate physical locations for design flexibility.

AI summary
To provide a warning lamp device for vehicles which makes it easy to recognize a power supply failure of a warning lamp (107, 110, 112, 106, 109, 105, 108) that is positioned in a location different from a meter with the power supply of the warning lamp (107, 110, 112, 106, 109, 105, 108) being separate from the power supply of the meter. A warning lamp device for a vehicle has a warning lamp (107, 110, 112, 106, 109, 105, 108) for detecting a state of a vehicle (1) and giving a warning when necessary. The warning lamp is disposed separately from a meter (37), a warning lamp power terminal (IGN+1) for supplying electric power to the warning lamp, and a meter power terminal (IGN+2), connected between a warning lamp power terminal (IGN+1) and the warning lamp, for supplying electric power to the meter, are provided, and the meter is supplied with electric power through the meter power terminal.
