Problem

Current anti-lock braking systems for two-wheelers are complex and costly to install, lacking a cost-effective and easy-to-implement solution for hydraulic modules that integrate with e-bikes and mopeds.

Innovation Solution

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

VSEngineering Contradiction Analysis

1Reliability

If anti-lock braking systems are implemented for two-wheelers, then safety is improved, but system complexity and installation cost increase

Engineering Contradiction:
ImprovesafetyVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

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.

Inventive Principle:
Principle #5Merging (Combining)

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.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If traditional anti-lock braking systems are installed, then braking control is achieved, but installation cost and complexity increase

Engineering Contradiction:
Improvebraking controlVSAvoidinstallation cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

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.

Inventive Principle:
Principle #5Merging (Combining)

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.

Inventive Principle:
Principle #1Segmentation

3Reliability

If multiple hydraulic components are used, then functional requirements are met, but housing material and weight increase

Engineering Contradiction:
Improvehydraulic functionVSAvoidhousing weight
Core Design Contradiction:
ReliabilityVSWeight of stationary object

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.

Inventive Principle:
Principle #5Merging (Combining)

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.

Inventive Principle:
Principle #6Universality (Multi-functionality)

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.
