Brake Fluid Pressure Control Device Base Weight Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing brake fluid pressure control devices face challenges in reducing weight while accommodating various brake line connection structures, leading to increased size and weight inefficiencies.
Innovation Solution
The design incorporates a base with protruding parts and flange-shaped or eave-shaped mounting seat surfaces on perpendicular faces, allowing for reduced weight and versatile connection compatibility without enlarging the device's size, effectively utilizing empty spaces on the housing and motor mounting surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mounting seat surface for brake line is formed on the base, then the brake line connection is secured, but the weight of the base increases
Solution Approach 1:
The base is divided into a main body and a protruding part. The protruding part is a separate structural element that extends from the main body and carries the mounting seat surface. This segmentation allows the mounting function to be isolated to a specific region, enabling weight reduction in the main body while maintaining connection security through the protruding part.
Solution Approach 2:
The mounting seat surface is moved from the main body surface to a protruding part that extends in the perpendicular direction. This dimensional change allows the mounting function to be achieved without increasing the planar dimensions of the base, and the protruding part can be optimized for minimal weight while maintaining structural integrity.
2Adaptability or versatility
If the base size is increased to accommodate various brake line connection structures, then connection versatility is improved, but the device size increases unnecessarily
Solution Approach 1:
The protruding part is designed with a mounting seat surface that can accommodate various brake line connection structures (flare type, banjo type, etc.). This single protruding structure serves multiple connection purposes, providing versatility without requiring separate base configurations for each connection type.
Solution Approach 2:
The protruding part is designed with specific local characteristics (flange shape or eave shape) that are optimized for mounting brake lines. This localized design concentrates the versatility function in a specific region, allowing the rest of the base to maintain a compact size while the protruding part handles various connection requirements.
3Weight of stationary object
If a protruding part with flange shape or eave shape is formed, then weight is reduced while maintaining mounting functionality, but the structural complexity increases
Solution Approach 1:
The protruding part combines multiple functions into a single structural element: it provides structural support, creates the mounting seat surface, and enables various brake line connections. By merging these functions into one integrated component, the overall structural complexity is managed while achieving weight reduction.

AI summary
A base of a brake fluid pressure control device for a vehicle includes a brake fluid passage formed therein. In one face, an insertion hole in which a brake line is to be inserted is formed, and, on at least one of perpendicular faces perpendicular to the one face, a protruding part is formed so as to protrude outward from the corresponding perpendicular face.
