Hydraulic Unit Layout With Transverse Simulator Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hydraulic units face challenges in achieving compact integration of the simulator due to the parallel alignment of the simulator receiving hole with the master cylinder receiving hole, limiting miniaturization without compromising functionality.
Innovation Solution
The simulator receiving hole is aligned transversely to the master cylinder hole, allowing for a compact integration within the block-shaped receiving body, sealed by a cap, and incorporating electronic components in the cap to enhance stability and functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the simulator receiving hole is aligned parallel to the master cylinder receiving hole, then the hydraulic unit can be manufactured with a conventional design, but the simulator cannot be compactly integrated into the block-shaped receiving body
Solution Approach 1:
The simulator receiving hole is aligned transversely to the master cylinder receiving hole, changing the spatial arrangement from parallel to perpendicular orientation. This dimensional reconfiguration allows the simulator to be compactly integrated into the block-shaped receiving body while maintaining conventional manufacturing processes.
2Volume of moving object
If the simulator receiving hole is aligned transversely to the master cylinder hole, then compact integration of the simulator is achieved, but the structural complexity of the receiving body increases
Solution Approach 1:
The simulator receiving hole is integrated directly into the block-shaped receiving body as a transverse hole, merging the simulator housing function with the receiving body structure. This consolidation eliminates separate simulator housing components and reduces overall structural complexity despite the transverse alignment.
3Volume of moving object
If the simulator is compactly integrated into the block-shaped receiving body, then miniaturization of the hydraulic unit is achieved, but the functionality of individual components may be restricted
Solution Approach 1:
The hydraulic unit is segmented into distinct functional zones within the block-shaped receiving body: the master cylinder hole for brake pedal actuation, the transverse simulator receiving hole for the brake pedal feel simulator, the through hole for the pressure generator, and valve receiving holes for pressure control valves. This segmentation allows each component to maintain its functionality while achieving compact overall integration.
Solution Approach 2:
Different regions of the block-shaped receiving body are optimized for specific functions: the transverse simulator receiving hole provides localized space for the simulator piston and spring mechanism, while the master cylinder hole accommodates the master cylinder piston. This localized optimization ensures each component has adequate space for its specific function despite the compact overall design.
