Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing motorcycle ABS system layouts fail to integrate the ABS unit effectively without increasing the overall dimensions, compromising the design and aerodynamics, particularly around the headlight and other essential components like the liquid tank.

Innovation Solution

The ABS unit is strategically located between the head pipe and the headlight, with a portion overlapping the headlight, allowing for compact integration and maintaining the headlight's position close to the head pipe, while also providing space for a liquid tank and article accommodating body.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the ABS unit is mounted in front of the head pipe through a bracket, then the ABS unit can be securely positioned, but the headlight must be disposed forwardly away from the ABS unit which increases the overall dimensions of the motorcycle

Engineering Contradiction:

ImproveABS unit positioningVSAvoidoverall dimensions

Core Design Contradiction:

ReliabilityVSLength of stationary object

Solution Approach 1:

The ABS unit is positioned such that it is nested within or adjacent to the headlight assembly structure. The ABS unit is disposed between the head pipe and the headlight, with part of it overlapping the headlight when viewed from above, allowing compact integration without increasing overall dimensions while maintaining secure positioning through the bracket mounted on the head pipe

Inventive Principle:

Principle #7Nested doll (Nesting)

2Reliability

If the ABS unit is positioned to allow secure mounting, then the ABS system can be reliably installed, but the degrees of freedom in designing the front portion of the motorcycle are strongly reduced

Engineering Contradiction:

ImproveABS system installationVSAvoiddesign freedom

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The front portion of the motorcycle is segmented into distinct functional zones: the head pipe mounting area for the ABS unit, the headlight assembly area, and the liquid tank area. The ABS unit is disposed between the head pipe and the headlight, allowing each component to be independently positioned and designed without compromising the others, thus maintaining design freedom while ensuring reliable ABS installation

Inventive Principle:

Principle #1Segmentation

3Length of stationary object

If the ABS unit is integrated compactly without increasing overall dimensions, then the motorcycle maintains contained dimensions and good aerodynamics, but the space required for accommodating the ABS unit must be properly designed to avoid negative effects on essential components

Engineering Contradiction:

Improveoverall dimensionsVSAvoidspace integration

Core Design Contradiction:

Length of stationary objectVSDevice complexity

Solution Approach 1:

The ABS unit is positioned in the vertical and depth dimensions between the head pipe and the headlight, with part of it overlapping the headlight when viewed from above. This three-dimensional arrangement allows the ABS unit to be integrated compactly without increasing the overall external dimensions of the motorcycle, while the bracket mounted on the head pipe provides secure positioning. The liquid tank is disposed behind the headlight, ensuring no interference with essential components

Inventive Principle:

Principle #17Another dimension (Dimensionality change)
