Integrated Brake Valve Assembly for Manual and Automatic Braking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional brake systems for machines require multiple valves and hydraulic/electrical lines for both operator and automatic braking modes, leading to increased complexity, cost, and space requirements.
Innovation Solution
A brake system with a brake valve assembly that includes an operator brake valve, an automatic brake valve, and a control valve, configurable between operator and automatic brake configurations, allowing for seamless switching between manual and automatic braking modes, reducing the need for multiple valves and lines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple valves and hydraulic/electrical lines are used for both operator and automatic braking modes, then the braking functionality is improved, but the device complexity increases
Solution Approach 1:
The patent combines the operator brake valve and automatic brake valve into a single integrated brake valve assembly with a common body. The first brake valve (operator) and second brake valve (automatic) share the same housing and are fluidly connected through internal passages, eliminating the need for separate valve assemblies and reducing overall system complexity while maintaining both braking modes.
Solution Approach 2:
The brake valve assembly is designed as a multi-functional unit that can operate in both operator-controlled mode and automatic braking mode. The control system can selectively activate either the first brake valve or second brake valve through a single assembly, allowing the same hardware to serve multiple braking functions without requiring separate dedicated systems.

AI summary
A brake system for a machine, where an operator brake valve is controllable by an operator input device and an automatic brake valve is controllable by a control system. A control valve is connected to a brake and the operator and automatic brake valves and operated by the control system between an operator brake configuration fluidly connecting the operator brake valve to the brake and an automatic brake configuration fluidly connecting the automatic brake valve to the brake in an operator braking mode, the control valve provides that the brake is controllable in response to an input to the operator input device. In an automatic braking mode the control valve provides that the brake is controllable in response to a control signal from the control system.
