Solution Overview

Problem

In saddle riding type vehicles, there is a need to minimize the support parts for brake piping between the braking force adjustment device and the front wheel brake.

Innovation Solution

The configuration includes a connecting part disposed behind the front fork, fixed to a stay extending forward from the down frame, with the flexible piping supported by a fender and a fender guard, allowing the flexible piping to be efficiently bent and supported using the rigidity of metal piping, and a sensor's cable fixed to the stay.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the brake piping is supported by multiple support parts between the braking force adjustment device and the front wheel brake, then the piping is well supported and protected, but the number of parts increases and structural complexity increases

Engineering Contradiction:
Improvesupport reliabilityVSAvoidnumber of support parts
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the support functions of multiple separate support parts into a single integrated stay structure. The stay extends from the down frame and provides both positioning and support for the brake piping, eliminating the need for multiple discrete support components while maintaining adequate support reliability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The stay structure serves multiple functions simultaneously: it supports the brake piping, positions the connecting part, and provides structural linkage between the down frame and the front fork assembly. This multi-functionality reduces the overall number of components needed in the braking system.

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

2Ease of manufacture

If the flexible piping is bent efficiently with proper support, then the piping layout is optimized, but additional support parts and structural complexity are required

Engineering Contradiction:
Improvepiping layout efficiencyVSAvoidstructural complexity
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The stay is pre-configured with the connecting part positioned at the appropriate location before final assembly. The flexible piping is routed through predetermined paths along the stay, allowing efficient bending and layout to be achieved during assembly without requiring complex support structures or additional adjustment steps.

Inventive Principle:
Principle #10Preliminary action
