Solution Overview

Problem

Vehicles, especially motorcycles, face challenges in maintaining optimal headlight and sensor orientation during leans, leading to reduced visibility and efficiency due to sub-optimum positioning, which affects the driver's awareness of the surroundings and the environment.

Innovation Solution

An adaptive lighting system that utilizes a lean angle sensor to control primary and secondary light elements, adjusting their illumination based on the vehicle's angle to ensure better visibility for the driver and oncoming traffic, while efficiently managing electrical resources.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If headlights are mounted to the vehicle frame, then the lighting system moves with the vehicle during leans, but the direction of the lights becomes oriented in a sub-optimum position

Engineering Contradiction:
Improvelighting system adapts to vehicle leanVSAvoidbeam direction accuracy
Core Design Contradiction:
Adaptability or versatilityVSIllumination intensity

Solution Approach 1:

The patent applies dynamics by making the lighting system adjustable and adaptive rather than fixed. The headlight assembly includes multiple light sources (primary low beam, primary high beam, and adaptive elements) that can be independently controlled and repositioned to compensate for vehicle lean angles, allowing the system to dynamically adapt to changing vehicle orientations during operation

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The lighting system is segmented into multiple independent light sources including primary low beam elements, primary high beam elements, and multiple adaptive elements. Each segment can be individually controlled and positioned to illuminate different areas, allowing the system to maintain optimal illumination patterns even when the vehicle is leaning

Inventive Principle:
Principle #1Segmentation

2Illumination intensity

If multiple light sources are used to maintain visibility during leans, then visibility is improved, but electrical current consumption increases

Engineering Contradiction:
ImprovevisibilityVSAvoidelectrical current consumption
Core Design Contradiction:
Illumination intensityVSUse of energy by moving object

Solution Approach 1:

The patent applies local quality by selectively activating specific light sources based on the vehicle's operational state. The controller activates only the necessary light elements (primary or adaptive) depending on the lean angle and driving conditions, ensuring that illumination is provided precisely where needed without wasting electrical energy on unnecessary light sources

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system changes operational parameters by adjusting which light sources are active based on lean angle thresholds. The controller monitors vehicle orientation and switches between different lighting configurations (primary low beam, primary high beam, adaptive elements) to optimize the balance between visibility and electrical current consumption

Inventive Principle:
Principle #35Parameter changes
