Motorcycle Registration Plate Positioning to Block Rider Glare
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motorcycle designs often position the vehicle registration plate in a way that it can be visible to the rider, potentially causing distractions and reducing visibility due to reflections from the headlight, and it is challenging to position the headlight and meter units near the center of gravity without obstructing the plate.
Innovation Solution
The motorcycle design positions the vehicle registration plate above the meter visor, with the headlight unit and meter unit placed near the center of gravity, utilizing a meter visor that overlaps the plate to prevent visibility issues and reflections from the headlight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the vehicle registration plate is positioned at the front of the motorcycle, then the plate is visible to the rider, but this causes distractions and reduces visibility due to reflections from the headlight
Solution Approach 1:
The vehicle registration plate is extracted from its conventional position in front of the headlight and relocated to the rear of the handlebar assembly. This separation removes the plate from the harmful reflection zone while maintaining its visibility function for external observers.
Solution Approach 2:
The handlebar assembly serves as an intermediary structure that carries the vehicle registration plate to a new position. By using the handlebar as a mounting platform, the plate is positioned behind the rider's line of sight while remaining visible to external observers, thus mediating between visibility requirements and distraction prevention.
2Stability of the object's composition
If the headlight unit and meter unit are positioned near the center of gravity, then optimal weight distribution is achieved, but this makes it challenging to position the vehicle registration plate without obstructing it
Solution Approach 1:
The handlebar assembly is given multiple functions: it serves as both a control interface and a mounting structure for the vehicle registration plate. This multi-functionality allows the plate to be positioned at the rear of the handlebar assembly without requiring additional support structures, thus maintaining center of gravity optimization while simplifying the overall arrangement.
Solution Approach 2:
Instead of positioning the plate in the conventional forward horizontal dimension, it is relocated to the rear horizontal dimension of the handlebar assembly. This dimensional repositioning resolves the conflict between center of gravity requirements and plate visibility by utilizing the available space in the opposite direction.

AI summary
A motorcycle (1) includes a head pipe (2a), a headlight unit (12) provided in front of the head pipe (2a) and including a headlight (18), a meter unit (11) provided above the head pipe (2a) and including a meter panel (11b), a meter visor (14) provided to cover the meter unit (11), and a vehicle registration plate (13) attached on the meter visor (14). Therefore, the vehicle registration plate (13) never comes within sight of the rider. Furthermore, the vehicle registration plate (13) does not get in the way when the headlight unit (12) and the meter unit (11) are positioned near the center of gravity of the motorcycle (1). The headlight (18) includes a light bulb (181) provided in the center in the motorcycle widthwise direction. The meter visor (14) overlaps the vehicle registration plate (13) in the center in the motorcycle widthwise direction from a view point in the orthogonal direction (XII) to the meter panel (11b). Therefore, light from the light bulb (181) of the headlight (18) reflected by the back surface of the vehicle registration plate (13) if any hardly comes in the rider's eyes.
