Motorcycle Windshield Light Guide Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Motorcycle drivers in the supersport segment often fail to notice shift light warnings due to high concentration on the road ahead, risking engine damage from exceeding critical engine speeds.
Innovation Solution
Integrating a display or warning device into the windshield, utilizing a light guide and light sources like LEDs to provide a centrally located warning signal that draws attention to the instrument cluster or headlight, ensuring the signal is more noticeable in the driver's field of vision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the display device is integrated into the windshield, then the visibility and centrality of the warning signal in the driver's field of vision is improved, but the device complexity increases
Solution Approach 1:
The display device is merged with the windshield structure, integrating the warning signal functionality directly into the existing windshield component. This combines two separate elements (display device and windshield) into one unified structure, improving visibility while avoiding the addition of separate complex components.
Solution Approach 2:
The windshield serves multiple functions: it provides structural protection and simultaneously acts as a display medium for warning signals. By making the windshield multi-functional, the patent eliminates the need for separate display components, thereby improving signal visibility without proportionally increasing device complexity.
2Loss of time
If the warning device is placed higher in the driver's field of vision, then the promptness of driver response is improved, but the ease of operation deteriorates due to driver distraction
Solution Approach 1:
The warning signal is localized to a specific region of the windshield that is centrally positioned in the driver's field of vision. By concentrating the warning function in this specific local area, the signal becomes highly visible and prompts immediate response without requiring the driver to shift attention to a different location, thus maintaining ease of operation.
Solution Approach 2:
The warning signal is positioned at an optimal height in the driver's field of vision where it is naturally visible without requiring the driver to change their viewing angle or focus. This creates an equipotential viewing condition where the warning signal and the road ahead are both within the driver's natural field of view, eliminating the need for additional attention shifts.
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
Significantly reduces the risk of overlooking warning signals by placing the warning device higher and more centrally in the driver's field of vision, enhancing visibility and promptness of response to critical engine speed alerts.
Implementation Method 1
The light rays are reflected in the windshield 1 (total reflection) and propagate up to an upper edge 5 of the windshield 1

AI summary
The motorcycle has electronics, which monitors a condition parameter, and produces a signal during presence of a pre-defined condition parameter. The signal controls a display device, a part of which is integrated in a windscreen (1) or is formed by the windscreen. The part of the windscreen is formed by a light conductor (4), where the signal is a light signal, which is coupled into the conductor. The windscreen is made of a transparent, light-guiding material, where the display device has a light source e.g. LED (3), which couples the light into the conductor.
