Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hydraulic blocks for brake pressure control mechanisms in vehicle brake systems face challenges in optimizing the arrangement and connection of hydraulic components for space efficiency and ease of assembly, particularly in systems with slip control features.
Innovation Solution
The hydraulic block is designed with non-straight-line arrangements of receptacles for inlet and outlet valves, offset configurations, and efficient line connections to accommodate components like the brake fluid reservoir and power cylinder bore, ensuring compact and secure integration of hydraulic components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If receptacles for inlet and outlet valves are arranged side by side in a straight line as usual, then the hydraulic block structure is simple, but the space utilization is poor and the arrangement is not compact
Solution Approach 1:
The receptacles for inlet and outlet valves are arranged in a non-linear offset configuration rather than a straight line, utilizing two-dimensional space more efficiently. This offset arrangement allows for more compact packaging of hydraulic components while maintaining functional connectivity, thereby improving space utilization without significantly increasing structural complexity.
2Adaptability or versatility
If the hydraulic block integrates multiple bores (master brake cylinder bore, power cylinder bore, simulator cylinder bore) and hydraulic components, then the brake pressure control functionality is enhanced, but the device complexity increases
Solution Approach 1:
The patent integrates the master brake cylinder bore, power cylinder bore, and simulator cylinder bore within a single hydraulic block structure. This merging of multiple functional bores into one consolidated component enhances brake pressure control functionality by enabling coordinated operation of different brake systems while reducing the overall number of separate components needed in the vehicle brake system.
Solution Approach 2:
The hydraulic block serves multiple functions simultaneously: it houses the master brake cylinder for conventional braking, the power cylinder for power-assisted braking, and the simulator cylinder for pedal feel simulation. This multi-functionality allows a single component to replace what would traditionally require multiple separate components, enhancing versatility while managing complexity through integration.
3Ease of operation
If the brake fluid reservoir connection line includes multiple bends, then the connection flexibility is improved, but the hydraulic path length increases and pressure loss may occur
Solution Approach 1:
The connection line between the brake fluid reservoir and the hydraulic block is designed with optimized curvature rather than sharp bends, allowing the hydraulic path to follow a smoother, more direct route. This curved path design maintains connection flexibility for installation purposes while minimizing the overall path length and reducing potential pressure losses compared to multiple sharp bends.
