A hydraulic module for anti-lock braking systems that includes a housing with integrated inlet and outlet valves, a pressure accumulator, and an electronic controller, utilizing standard automotive components and a simple assembly process, allowing for easy attachment to two-wheelers with minimal material and weight, and enabling efficient brake fluid management and electronic control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If anti-lock braking systems are implemented for two-wheelers, then safety is improved, but system complexity and installation cost increase
Solution Approach 1:
The patent combines multiple hydraulic components (inlet valve, outlet valve, and pressure accumulator) into a single integrated hydraulic module with a common housing. This merging of previously separate components reduces the overall system complexity and number of installation points while maintaining the safety functions of the anti-lock braking system.
Solution Approach 2:
The hydraulic module serves multiple functions simultaneously: the inlet valve controls brake fluid flow from the reservoir, the outlet valve manages fluid return to the accumulator, and the pressure accumulator maintains system pressure. This multi-functionality within a single module simplifies the overall system architecture.
2Reliability
If traditional anti-lock braking systems are installed, then braking control is achieved, but installation cost and complexity increase
Solution Approach 1:
By consolidating the inlet valve, outlet valve, and pressure accumulator into one manufactured unit with a single housing, the system reduces the number of separate parts that need to be sourced, inventoried, and installed. This merging directly lowers installation cost and simplifies the manufacturing supply chain.
Solution Approach 2:
The hydraulic module is designed as a self-contained segment that can be installed as a single unit into the two-wheeler's hydraulic system. This segmentation into a modular component simplifies installation procedures and reduces labor costs compared to installing multiple separate components.
3Reliability
If multiple hydraulic components are used, then functional requirements are met, but housing material and weight increase
Solution Approach 1:
Instead of providing separate housings for the inlet valve, outlet valve, and pressure accumulator, the patent merges all three components into a single common housing. This eliminates redundant housing materials and reduces the total weight of the hydraulic system while maintaining all necessary hydraulic functions.
Solution Approach 2:
The common housing serves multiple purposes: it encloses the inlet valve, encloses the outlet valve, and provides the pressure accumulator chamber. This multi-functional housing design reduces the total material required compared to having separate housings for each component.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The hydraulic module provides a cost-effective, easy-to-install anti-lock braking system for two-wheelers, enhancing safety by effectively managing brake fluid pressure and electronically controlling the braking process, reducing the complexity and cost of installation while ensuring reliable operation.
Implementation Method 1
The pressure accumulator can have a spring element that is tensioned when the pressure accumulator is filled. For example, the pressure accumulator can be emptied again by pushing back the piston.
Implementation Method 2
The pressure accumulator is designed to feed brake fluid back into the hydraulic connection between the inlet valve and the wheel brake, for example by reducing its variable volume.
