Composite Ground-Projection Warning Lamp for Vehicle Turning Blind Spots
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicles turning create a blind spot due to the difference in wheel radius, making it difficult for drivers to notice pedestrians or cyclists, and existing solutions only provide reference information for drivers without warning external passers-by, leading to potential collisions.
Innovation Solution
A multi-lighting projection warning device that projects warning lighting on the ground when a vehicle is turning, using a composite lamp with range, contour, and text/pattern indicator lights, controlled by a unit that adjusts lighting and sound alarms to create a clear warning area, detect objects, and adjust based on vehicle parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple types of vehicles (motorcycles, cars, buses, trucks) are considered for the warning device, then the adaptability of the device is improved, but the device complexity increases due to the need to accommodate different vehicle sizes and blind spot areas
Solution Approach 1:
The warning device is designed as a universal system that can be applied to multiple vehicle types (motorcycles, cars, buses, trucks) with different blind spot characteristics. The device uses a standardized composite lamp structure with range indicator light, contour indicator light, and text/pattern indicator light that can adapt to various vehicle sizes through adjustable projection parameters and multiple lamp configurations, achieving multi-functionality without requiring completely different systems for each vehicle type.
Solution Approach 2:
The warning device is divided into three functional segments: range indicator light for illuminating the warning area, contour indicator light for marking boundaries, and text/pattern indicator light for enhanced visibility. This segmentation allows each component to be optimized independently while maintaining overall adaptability across different vehicle types, reducing the complexity of designing a completely integrated system for each vehicle.
2Reliability
If the composite lamp projects lighting towards the visual blind spot to form a warning area, then the warning effectiveness is improved, but the energy consumption increases due to multiple indicator lights operating simultaneously
Solution Approach 1:
The control unit can operate the composite lamp in periodic cycles, activating the range indicator light, contour indicator light, and text/pattern indicator light in sequence or in coordinated flashing patterns rather than maintaining continuous operation of all lights. This periodic activation maintains warning effectiveness by creating attention-grabbing visual patterns while significantly reducing overall energy consumption compared to continuous operation.
Solution Approach 2:
The control unit can selectively activate only the necessary indicator lights based on detection results and environmental conditions. For example, if objects are detected in the blind spot, the system activates the relevant indicator lights (range, contour, or text/pattern) to provide adequate warning, rather than always operating all lights at full capacity. This partial action approach maintains reliability when needed while reducing energy consumption during normal operation.
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 device effectively warns pedestrians and cyclists of an approaching vehicle's turning path, reducing collision risks by providing a clear and obvious warning area through adjustable lighting and sound, enhancing road safety.
Implementation Method 1
The composite lamp projects lighting towards a visual blind spot of the turning vehicle to form a warning area

AI summary
The invention discloses a multi-lighting projection warning device for vehicle turning, which comprises a composite lamp and a control unit. The composite lamp is arranged on one side of a vehicle and combined with a range indicator light, a contour indicator light, and a text or pattern indicator light, so that the composite lamp can project lighting to a visual blind spot when the vehicle turns or reverses to form a warning area. The control unit is connected to the composite lamp to enable functions of controlling rotation and start-stop lighting of the composite lamp. Thereby, when the vehicle is turning, the invention projects composite lightings on the ground at the turning side to form the warning area, so as to actively warn other passers-by to dodge the warning area and increase the safety of passers-by.
