Solution Overview

Problem

Conventional motorcycle light units with a common outer lens covering the headlight and flasher lamps make it difficult to identify the state of the headlight and flasher lamps being lit, resulting in reduced visibility.

Innovation Solution

A handlebar cover with interposed parts extending downward between the headlight and flasher lamps, creating a visual separation while using a common outer lens, allowing easier identification of the lit state.

1Device complexity

If a common outer lens covers the headlight and flasher lamps, then the appearance is unified and simple, but it becomes difficult to identify the state of the headlight and flasher lamps being lit

Engineering Contradiction:
Improvelight unit structureVSAvoidvisibility of lamp state
Core Design Contradiction:
Device complexityVSDifficulty of detecting and measuring

Solution Approach 1:

The light opening is segmented into a headlight light opening and flasher lamp light openings by the interposed parts, allowing visual distinction between different lamp types while maintaining a unified outer lens structure

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The interposed parts of the handlebar cover act as an intermediary element that visually separates the headlight and flasher lamps, helping riders and other road users distinguish which lamps are illuminated without requiring separate lens structures

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A motorcycle wherein it is possible to easily identify the state of a headlight and flasher lamps covered with a common outer lens. A a headlight is disposed in a central portion of a light unit in a transverse direction of the motorcycle. A pair of left and right flasher lamps is disposed on left and right sides of the headlight. A common outer lens covers the left and right flasher lamps and the headlight. An upper edge of a light opening in a handlebar cover has left and right interposed parts extending downward to be interposed between the headlight and the left and right flasher lamps.
