Solution Overview

Problem

The existing motorcycle designs face poor assemblability due to separate support requirements for hydraulic tubes and cables, and the attachment of instruments, which complicates the installation process.

Innovation Solution

A motorcycle with a harness support structure that includes a cable bracket and an instrument bracket, featuring a grommet member with a U-shaped configuration and projecting pieces to securely hold and guide the cable members, preventing forward movement and facilitating compact support.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If hydraulic tubes and cables are supported separately from instruments, then each component can be individually secured, but the assemblability deteriorates due to multiple separate attachment operations

Engineering Contradiction:
ImproveassemblabilityVSAvoidnumber of separate support operations
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent combines the cable support function and instrument support function into a single integrated cable bracket structure. The bracket simultaneously holds cable members and supports instruments, eliminating the need for separate support operations and improving assemblability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The cable bracket is designed as a multi-functional component that performs multiple tasks: supporting cable members, supporting instruments, and providing structural attachment to the vehicle body. This universal design reduces the total number of components and assembly steps.

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

2Reliability

If cable members are held at multiple positions, then forward movement is prevented, but the structure becomes more complex with additional components

Engineering Contradiction:
Improvecable position stabilityVSAvoidstructure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The holding portion and regulating portion are integrated into a single cable bracket structure rather than being separate components. This merging maintains cable position stability through multiple fixation points while avoiding the complexity of additional independent parts.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The cable bracket is divided into functional segments (holding portion, regulating portion, instrument support portion) that work together within a single integrated component, allowing each segment to perform its specific function while maintaining overall structural simplicity.

Inventive Principle:
Principle #1Segmentation

AI summary

In a harness support structure for a motorcycle, a cable bracket (50) is supported by a top bridge (4), and an upper lamp bracket (28) for supporting a headlamp device (40) is fitted to the cable bracket (50). A first holding portion (56) for holding an intermediate portion of cable members (44) having respective one end portion connected with a handle (10) is provided in the cable bracket (50). The cable bracket (50) is provided with a regulating portion (120) for inhibiting a forward movement of the cable member (44) at a location distant from a handle side rather than the first holding portion (56).
