Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

In straddle-type vehicles, the installation of handle bars is restricted by the proximity of components such as master cylinders and levers, limiting the design freedom of handle bar installation positions, directions, and shapes due to interference concerns.

Innovation Solution

The handle bars are designed with a base portion and a handle holder that extend inward in the vehicle width direction, fixed to the upper bracket using fixing members, allowing for independent positioning and reducing interference with nearby components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If handle bars are installed using clamp members on the upper bracket as described in prior art, then the handle can be securely fixed to the front forks, but the design freedom of handle bar installation positions, directions, and shapes is restricted due to interference with nearby components such as master cylinders and levers

Engineering Contradiction:

Improvedesign freedom of handle barVSAvoidinterference with components

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent transitions from a conventional horizontal handle bar configuration to a vertical handle bar configuration that extends in the vehicle height direction. This dimensional change allows the handle bar to be positioned away from interfering components in the vehicle width direction, thereby resolving the contradiction between design freedom and component interference.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The handle bar is divided into multiple segments including a first handle bar, a second handle bar, and a connection portion. This segmentation allows each part to be independently positioned and oriented, enabling the handle bar assembly to navigate around interfering components while maintaining structural integrity and design flexibility.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If handle bars are positioned to avoid interference with components, then design freedom is improved, but the structural complexity and number of parts increase

Engineering Contradiction:

Improveinstallation flexibilityVSAvoidstructure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The connection portion integrates multiple functions: it connects the first and second handle bars, provides positioning features for accurate alignment, and incorporates fixing members for secure attachment to the upper bracket. By merging these functions into a single integrated component, the patent reduces overall structural complexity while maintaining installation flexibility.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The connection portion serves multiple purposes simultaneously: structural connection, positioning, and fixation. This multi-functionality eliminates the need for separate components for each function, thereby reducing device complexity while achieving the desired installation flexibility.

Inventive Principle:

Principle #6Universality (Multi-functionality)
