Solution Overview

Problem

The accommodation of a position lamp within a lamp unit with a headlamp increases the size of the lamp unit and the front fairing, limiting the design flexibility of the motorcycle's front fairing and headlamp structure, especially when trying to mount a single position lamp at an intermediate motorcycle portion.

Innovation Solution

A position lamp mounting structure that includes a top bridge supporting the front fork assembly, a handle holder clamping the handlebar, and a lamp holder integrated with the handle holder, allowing the lamp unit to be mounted separately from the headlamp support structure, with a lamp unit that can be removably fastened and features left and right arm portions to cover the sides of the lamp main body, improving the exterior look and facilitating easy replacement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the position lamp is accommodated within the lamp unit together with the headlamp, then the lamp unit can be integrated, but the size of the lamp unit and front fairing increases

Engineering Contradiction:
Improvelamp unit integrationVSAvoidfront fairing size
Core Design Contradiction:
Device complexityVSArea of stationary object

Solution Approach 1:

The patent divides the lighting system into separate functional units: the headlamp remains mounted on the front fairing while the position lamp is separated and mounted on the handle holder. This segmentation allows each component to be optimized independently, reducing the overall size requirement of the front fairing while maintaining functional integration through separate mounting locations.

Inventive Principle:
Principle #1Segmentation

2Area of stationary object

If the position lamp is supported separately from the headlamp on the front fairing, then the front fairing size can be reduced, but the selection of mounting site becomes problematic

Engineering Contradiction:
Improvefront fairing sizeVSAvoidmounting site selection
Core Design Contradiction:
Area of stationary objectVSAdaptability or versatility

Solution Approach 1:

The handle holder is designed to serve multiple functions: it supports the handlebar, provides mounting for the position lamp, and integrates with the motorcycle's steering mechanism. This multi-functionality allows the position lamp to be mounted at an intermediate portion of the motorcycle body that is both aesthetically appropriate and structurally sound, resolving the mounting site selection problem.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If the position lamp is mounted on the front fork assembly separately from the headlamp, then the mounting location can be optimized, but the structure cannot be applied to a single position lamp at the motorcycle intermediate portion

Engineering Contradiction:
Improvemounting location optimizationVSAvoidstructure applicability
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The handle holder acts as an intermediary structure between the front fork assembly and the position lamp. It provides a suitable mounting interface for the position lamp at the motorcycle's intermediate portion, bridging the gap between the front fork assembly structure and the lighting requirements, thereby enabling optimal mounting location while maintaining structural simplicity.

Inventive Principle:
Principle #24Intermediary (Mediator)
