Hydraulic Pressure Control Unit Layout for Larger Control Boards
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hydraulic pressure control units for straddle-type vehicles face challenges in accommodating the control board due to the downsizing of the base body, leading to difficulties in housing the components effectively.
Innovation Solution
The hydraulic pressure control unit is designed with a housing that projects in two directions from the base body, creating a larger accommodation space for the control board, while maintaining the same base body size, and includes a connector positioned to project outward, allowing for improved space utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the base body is downsized to reduce weight, then the weight of the hydraulic pressure control unit is reduced, but the accommodation space for the control board in the housing becomes insufficient
Solution Approach 1:
The housing is designed to project in a direction substantially perpendicular to the alignment direction of the base body, creating additional three-dimensional space. This dimensional extension allows the control board to be accommodated in the housing without increasing the footprint area of the base body, thus maintaining weight reduction while providing sufficient accommodation space for the control board and its components
2Length of moving object
If the housing projects only in the alignment direction of the base body, then the overall length is reduced, but the control board cannot be accommodated effectively
Solution Approach 1:
The housing extends in a direction substantially perpendicular to the alignment direction of the base body, utilizing vertical or lateral space rather than extending the overall length. This dimensional change allows effective accommodation of the control board with multiple components while keeping the overall length compact and manageable
3Device complexity
If the connector is positioned inside the base body projection area, then the structure is compact, but the control board accommodation space is reduced
Solution Approach 1:
The connector is positioned in the housing that projects in a direction substantially perpendicular to the base body alignment direction. This spatial separation places the connector outside the base body projection area when viewed from the alignment direction, preventing interference with the control board accommodation space while maintaining structural compactness through integrated housing design

AI summary
The invention obtains a hydraulic pressure control unit for a straddle-type vehicle that facilitates accommodation of a control board in a housing in comparison with a conventional hydraulic pressure control unit.The hydraulic pressure control unit according to the invention includes: a base body formed with a brake fluid channel; a control board to which at least some of components of a brake controller for controlling a hydraulic pressure regulation valve opening/closing the channel are mounted; a housing accommodating the control board; and a connector electrically connected to the control board. When being observed in a viewing direction that is parallel to an alignment direction of the base body and the housing and in which the base body and the housing are aligned in this order, the connector is provided in an area, which is projected to an outer side of the base body in a first direction as one of four directions extending in an up-down direction and a right-left direction, in the housing, and the housing is also projected to the outer side of the base body in a second direction that is one of the four directions and differs from the first direction.
