Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hydraulic blocks for hydraulic power brake systems face challenges in efficiently integrating and connecting hydraulic components, such as solenoid valves and brake fluid lines, within a right-parallelpiped-shaped structure, which affects the overall functionality and efficiency of brake pressure regulation.
Innovation Solution
The hydraulic block is designed with a power brake cylinder bore passing through from one side to the opposite side, featuring receptacles for solenoid valves and other hydraulic components, and includes brake fluid lines that are introduced parallelly and perpendicularly to the sides and edges, allowing for a modular construction with separate pressure-generating and pressure-regulating modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hydraulic components are integrated within a right-parallelpiped-shaped hydraulic block, then the brake pressure regulation functionality is improved, but the complexity of integrating and connecting hydraulic components increases
Solution Approach 1:
The hydraulic block is segmented into distinct functional zones: a motor side for the power brake piston and cylinder bore, and a valve side for solenoid valves and hydraulic components. This segmentation organizes the integration of multiple hydraulic components, reducing connection complexity while maintaining reliable brake pressure regulation functionality.
2Productivity
If a power brake cylinder bore passes through the hydraulic block from one side to the opposite side, then the brake pressure generation efficiency is improved, but the structural complexity of the hydraulic block increases
Solution Approach 1:
The power brake cylinder bore serves multiple functions: it accommodates the power brake piston for brake pressure generation, provides a mounting structure for the electric motor and ball screw mechanism, and facilitates hydraulic fluid flow through the block. This multi-functionality improves brake pressure generation efficiency while avoiding additional structural complexity.
3Adaptability or versatility
If receptacles for solenoid valves and hydraulic components are provided on the valve side, then the brake pressure regulation capability is improved, but the manufacturing complexity of the hydraulic block increases
Solution Approach 1:
Receptacles for solenoid valves and hydraulic components are pre-formed during the hydraulic block manufacturing process, with standardized geometries and positions. This preliminary action enables easy assembly of brake pressure regulation components while maintaining manufacturing efficiency, avoiding complex post-processing operations.
