Motorcycle ABS Modulator Outer Frame Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in motorcycle brake systems is the difficulty in arranging a hydraulic modulator without occupying space meant for other components, particularly in limited areas like the head pipe and front cowl, while ensuring a rigid and weight-efficient support structure.
Innovation Solution
The hydraulic modulator is positioned on the outer side of the body frames and inside the vehicle body cover, supported by inclined main pipes and seat rails, allowing for a larger space utilization without encroaching on other components and utilizing high-rigidity structures for support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the hydraulic modulator is arranged in limited spaces such as the head pipe or front cowl area, then the supporting structure can be compact, but the arrangement space for other components such as the induction system is reduced and the layout becomes difficult
Solution Approach 1:
The patent transitions from arranging the hydraulic modulator in the longitudinal direction (head pipe area) or upper space (front cowl) to utilizing the lateral dimension by positioning it on the outer side of the body frames. This dimensional shift provides sufficient arrangement space for the modulator without encroaching on the induction system or other component spaces.
2Area of stationary object
If the hydraulic modulator is arranged in limited spaces, then the overall vehicle size can be reduced, but the supporting structure requires additional weight to ensure sufficient rigidity
Solution Approach 1:
The body frames serve dual functions: they provide the structural framework for the vehicle and simultaneously serve as the supporting structure for the hydraulic modulator. By utilizing the existing body frames for both purposes, the patent eliminates the need for separate dedicated support structures, thereby reducing overall weight while ensuring sufficient rigidity.
3Weight of stationary object
If the hydraulic modulator is supported on high-rigidity structures such as body frames, then the supporting member weight can be reduced, but the modulator must be arranged in specific locations that may not be readily accessible
Solution Approach 1:
The patent positions the hydraulic modulator on the outer side of the body frames, which provides both structural advantages (utilizing high-rigidity body frames for support) and operational advantages (improved accessibility for installation and maintenance compared to confined internal spaces). This lateral positioning allows technicians to access the modulator from the outside without disassembling other components.

AI summary
An ABS modulator for a front wheel is supported on the side surface of an inclined portion located forward of a portion, having the largest width, of the right main pipe with a unit supporting stay in between, while being arranged in a space inside the front cowl covering the front side of the inclined portion. The ABS modulator is arranged on the outer side of the main pipe. Accordingly, it is possible to avoid a case where the arrangement space for other components is occupied by arranging the ABS modulator in a space on the inner side of the right and left main pipes, and to support the ABS modulator by utilizing the main pipes having a high rigidity. Further, the resulting configuration allows to ABS modulator to be located in a portion having a high rigidity without occupying a space for other components, such as an induction system.
