Road Roller Water Tank Plug Connection Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing self-propelled road rollers face challenges in efficiently mounting and verifying the connection of service water tanks due to the time-consuming and error-prone process of using flexible hoses, which are susceptible to misalignment.
Innovation Solution
The service water tank is connected via a flexurally rigid connection pipe with sealed insertion openings and axial stoppers, allowing for a plug connection that simplifies mounting and ensures correct positioning, with tie rods for secure fastening and symmetrical arrangement for optimal space utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a flexible hose with hose clips is used to connect the tank bodies, then the mounting process is time-consuming and susceptible to mounting errors, but the connection allows for flexibility in positioning
Solution Approach 1:
The service water tank is divided into two separate tank bodies (first tank body and second tank body) that are connected via a plug connection system. This segmentation allows independent positioning while ensuring reliable connection through the standardized plug interface with sealing elements, resolving the contradiction between mounting speed and connection reliability.
Solution Approach 2:
A connection pipe serves as an intermediary element between the two tank bodies, providing a standardized plug connection interface. This intermediary component with integrated sealing ensures quick and reliable connection without requiring complex hose clipping procedures, thereby reducing mounting time while maintaining connection reliability.
2Ease of operation
If a flexible hose is used for connection, then positioning flexibility is achieved, but verification of correct mounting is difficult
Solution Approach 1:
The plug connection system incorporates visual indicators (such as colored sealing elements or positioning features) that allow operators to quickly verify correct mounting by simple visual inspection. This eliminates the difficulty of verifying hose connections while maintaining the necessary connection structure without excessive complexity.
3Reliability
If hose clips are used to secure the flexible hose, then the connection can be secured, but the mounting process becomes complex and error-prone
Solution Approach 1:
The plug connection integrates multiple functions into a single component: connection, sealing, and positioning. This merging eliminates the need for separate hose clips and sealing elements, simplifying the mounting process while maintaining connection security through the integrated plug interface that combines these functions.
Solution Approach 2:
The plug connection system is designed to be self-aligning and self-sealing, requiring no additional fastening components. The tapered plug interface automatically positions itself during insertion, and the integrated sealing element creates a leak-proof connection without requiring separate sealing compounds or clips, thereby simplifying mounting while ensuring reliable connection security.
