Motorcycle Headlight and Side Stand Height Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motorcycle vehicle height control systems do not effectively manage auxiliary devices such as headlights, side stands, rearview mirrors, and brakes with ABS, leading to inappropriate illumination and potential hindrance of oncoming drivers due to fixed optical axes and inadequate adjustments with varying vehicle heights.
Innovation Solution
Incorporating vehicle height detection means within the damper system to control auxiliary devices like headlights, side stands, rearview mirrors, and brakes with ABS, adjusting their positions or functions based on detected vehicle height to ensure optimal operation and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the headlight optical axis is fixed in the same position, then the headlight structure is simple, but the illumination range becomes inappropriate when vehicle height changes
Solution Approach 1:
The headlight optical axis is made adjustable rather than fixed. The optical axis position can dynamically change based on vehicle height detection, allowing the headlight to project illumination at appropriate angles whether the vehicle is in stoppage or travel height position, optimizing illumination effectiveness for each state.
2Device complexity
If the side stand length is fixed, then the side stand structure is simple, but the motorcycle cannot be properly supported when vehicle height changes
Solution Approach 1:
The side stand length is made variable to match vehicle height changes. When the vehicle height is adjusted between stoppage and travel positions, the side stand automatically adjusts its extended length to ensure it can properly contact the ground and support the motorcycle in each height state, preventing instability or failure to support.
3Device complexity
If the rearview mirror position is fixed, then the mounting structure is simple, but rear visibility becomes inadequate when vehicle height changes
Solution Approach 1:
The rearview mirror position is made adjustable based on vehicle height detection. When the vehicle height changes between stoppage and travel positions, the rearview mirror automatically adjusts its angular or positional orientation to maintain optimal viewing angles for the rider, ensuring continuous rear visibility regardless of height state.
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
This solution ensures appropriate illumination for the rider, prevents hindrance of oncoming drivers, maintains stable brake operability, and ensures rear visibility by dynamically adjusting auxiliary devices according to the vehicle's height changes.

AI summary
An object of the present invention is to control according to a vehicle height an auxiliary device provided in a vehicle. A motorcycle 1 having a damper 10A interposed between a vehicle body and an axle includes vehicle height detection means 80 for detecting a vehicle height, with this vehicle height detection means being provided in the damper 10A in an auxiliary manner. The optical axis of a headlight 210, which is an exemplar auxiliary device provided in the vehicle, is controlled based on a detection signal from the vehicle height detection means 80.
