Solution Overview
Problem
Existing hydraulic supply systems for rail vehicles face challenges in optimizing space, weight, and functionality density, while maintaining reliable operation and reducing costs.
Innovation Solution
The proposed hydraulic supply system incorporates a flange that mechanically couples the drive motor and hydraulic pump, while also providing electrical and hydraulic couplings to the control plate, thereby increasing functionality density and reducing installation space and weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If traditional hydraulic supply systems are used with separate mounting of drive motor, hydraulic pump, and control plate, then ease of manufacture and assembly are improved, but installation space and weight are increased
Solution Approach 1:
The flange is designed as a single component that combines multiple functions: mechanical coupling of drive motor and hydraulic pump, electrical coupling via electrical coupling elements, and hydraulic coupling via connectors. This merging of previously separate components into one integrated flange reduces installation space while maintaining ease of assembly through standardized coupling interfaces.
Solution Approach 2:
The flange serves multiple functions simultaneously: it acts as a mechanical coupling element, an electrical coupling component, and a hydraulic coupling device. This multi-functionality allows the single component to replace what would traditionally require multiple separate parts, thereby reducing overall installation space and component count.
2Weight of stationary object
If multiple separate components are used for mechanical, electrical, and hydraulic couplings, then ease of repair and maintenance are improved, but weight and installation space are increased
Solution Approach 1:
By combining mechanical coupling, electrical coupling elements, and hydraulic connectors into a single flange component, the overall system weight is reduced. The integrated design eliminates the need for multiple separate coupling components, thereby achieving weight reduction while maintaining standardized interfaces that facilitate repair and maintenance.
3Area of stationary object
If functionality density is increased by integrating more components, then installation space is reduced, but device complexity and manufacturing difficulty are increased
Solution Approach 1:
The flange is designed as a universal component that performs mechanical, electrical, and hydraulic coupling functions. By standardizing the flange design with integrated coupling interfaces, the manufacturing process is simplified compared to producing multiple specialized components, while achieving high functionality density in a single part.
