Motorcycle Lamp Tilt Compensation With Auxiliary Corner Lighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional motorcycle lamps fail to compensate for the displacement of the illumination area caused by the tilted state of the vehicle, resulting in incomplete illumination and blind spots during turns, which poses significant driving safety risks.
Innovation Solution
A motorcycle lamp design featuring two main light devices and two auxiliary light devices, controlled by a tilt angle detector and controller, adjusts the illumination based on the motorcycle's tilt angle to provide a wide illumination range without blind spots, using light emitting diodes and auxiliary light lenses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the motorcycle lamp tilts with the vehicle body during turns, then the illumination area tilts accordingly, but this results in incomplete illumination and blind spots ahead
Solution Approach 1:
The patent employs a tilt angle detector to dynamically sense the motorcycle's inclination angle during turns, and a controller dynamically adjusts the illumination pattern by selectively activating auxiliary light devices based on the detected tilt angle, ensuring continuous and complete illumination coverage despite vehicle tilting
Solution Approach 2:
The system changes the illumination parameters (which specific light devices are activated, their intensity, and timing) based on the tilt angle parameter detected by the sensor, transitioning from a static illumination pattern to a dynamic one that compensates for the tilted state
2Reliability
If conventional motorcycle lamps are used without tilt compensation, then the structure is simple, but illumination blind areas occur during turns
Solution Approach 1:
The patent introduces auxiliary light devices as intermediary elements that specifically compensate for the illumination blind areas created during turns, working in conjunction with the main light devices to provide complete coverage without requiring a complete redesign of the entire lighting system
Solution Approach 2:
The patent replaces complex mechanical adjustment mechanisms with an electronic control system consisting of a tilt angle detector and controller that automatically adjusts illumination based on sensed vehicle state, simplifying the overall system while achieving tilt compensation
