Solution Overview
Problem
Existing hydraulic units for slip-controlled brake systems, particularly in motorcycles, face challenges in reducing overall dimensions and manufacturing effort while maintaining effective brake control functions.
Innovation Solution
The hydraulic unit incorporates a block-shaped accommodating member with inlet and outlet valves arranged in a single valve row, connected by pressure fluid channels that minimize dimensions and manufacturing complexity, allowing for efficient brake pressure distribution and control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the hydraulic unit uses a conventional block-shaped accommodating member with multiple valve rows and complex pressure fluid channels, then the brake control function is effective, but the overall dimensions and manufacturing effort increase
Solution Approach 1:
The patent merges the inlet and outlet valves into a single integrated valve unit with a common valve body, eliminating the need for separate valve blocks and reducing the number of pressure fluid channels required. This consolidation directly reduces the accommodating member dimensions while simplifying manufacturing operations.
Solution Approach 2:
The single valve unit performs multiple functions by incorporating both inlet and outlet valves in one component, allowing a single manufacturing process to produce all valve-related features rather than requiring separate operations for each valve type.
2Ease of manufacture
If the hydraulic unit reduces the number of valve rows to a single valve row, then the manufacturing complexity decreases, but the brake control function may be compromised
Solution Approach 1:
The patent combines inlet and outlet valves into a single integrated unit where both valve types share a common valve body and control mechanism, maintaining the functional separation needed for brake control while achieving manufacturing simplicity through unified construction.
Solution Approach 2:
Within the single valve unit, the inlet and outlet valves are functionally segmented with separate control mechanisms and fluid paths, ensuring that the simplified structure does not compromise the distinct brake control functions required for reliable operation.
3Device complexity
If the pressure fluid channels are arranged in a conventional manner with multiple connections, then the brake pressure distribution is effective, but the device complexity increases
Solution Approach 1:
The patent merges multiple pressure fluid channel functions into the single integrated valve unit, where internal passages handle pressure distribution to both inlet and outlet valves, eliminating the need for complex external channel arrangements while maintaining effective brake pressure distribution.
