Solution Overview

Problem

Current ABS systems in motorcycles and motor vehicles face issues with long connecting piping that can deform, require complex assembly, and are prone to hydraulic fluid flow disruptions, necessitating specialized installation and maintenance.

Innovation Solution

A compact ABS system with integrated ABS unit and dividing valves, utilizing rigid connection tubes and a unified support structure to reduce piping length, enhance mechanical strength, and simplify assembly by pre-assembling components off-line.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If long flexible piping is used to connect ABS unit and dividing valves positioned in remote locations, then the system can accommodate distributed component layout, but the piping may deform and be crushed compromising system operation

Engineering Contradiction:
Improvecomponent layout flexibilityVSAvoidpiping operation reliability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent merges the ABS unit and dividing valves into a single integrated housing assembly, eliminating the need for long flexible piping connections between remotely positioned components. This consolidation resolves the contradiction by providing both structural reliability and adaptability through the integrated design that can be positioned as a unified unit.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent segments the braking system into the integrated ABS unit/dividing valve assembly and the wheel brake components, with rigid piping connecting only where structurally sound. This segmentation allows the critical control components to be housed together while maintaining flexibility in overall system configuration.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If long connecting piping is used between ABS unit, valves and brake components, then component placement flexibility is improved, but assembly complexity and connection errors increase

Engineering Contradiction:
Improvecomponent placement flexibilityVSAvoidassembly complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

By combining the ABS unit and dividing valves into a single integrated assembly with pre-connected piping, the patent reduces the number of separate connections from ten or more to just one or two connection points. This merging dramatically simplifies assembly while maintaining the ability to position the integrated assembly flexibly within the vehicle.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent implements preliminary action by pre-assembling the ABS unit, dividing valves, and connecting piping into an integrated unit before installation. This pre-integration eliminates the need for complex on-site assembly and reduces the risk of connection errors during installation.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If flexible piping is used to connect ABS components, then installation flexibility is improved, but mechanical strength and resistance to high pressure are reduced

Engineering Contradiction:
Improveinstallation flexibilityVSAvoidpiping strength
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The integrated housing design combines rigid structural support with the ABS unit and dividing valves, eliminating the need for separate flexible piping. This provides both the mechanical strength of rigid construction and the installation flexibility of a pre-assembled unit that can be positioned as a whole.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent employs composite construction principles by integrating multiple components into a unified housing structure that combines rigid materials for strength with design flexibility. This composite approach maintains high mechanical strength while allowing adaptable installation.

Inventive Principle:
Principle #40Composite materials

AI summary

A compact system (1) for ABS is described comprising an ABS unit (2), at least one dividing valve (3, 3) and a support (4). The support (4), in turn, comprises a housing compartment (5) for the ABS unit (2) and at least one housing seat (6) for said at least one dividing valve (3, 3). This means that at least one housing seat (6) is positioned so as to be adjacent to the housing compartment (5). A method for assembling of an ABS system on a motorcycle or motor vehicle as well as a motorcycle or motor vehicle assembled by means of such a method and a motorcycle or motor vehicle comprising a system (1) are also described.
