Modular Hose Connection Kit for Fuel Dispensing Units
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly of hose connections in fuel dispensing units is complex and time-consuming due to the large number of components, and existing systems lack the ability to blend fuels with varying octane ratings, complicating vapour recovery piping connections.
Innovation Solution
A kit of parts comprising hose connection components with varying inlet and outlet configurations allows for simplified assembly and blending of fuels, featuring vapour recovery ports and O-ring seals for reliable sealing, reducing the overall number of components and enabling fuel blending.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional hose connections use multiple separate components (pipe, hose, intermediate member, locking device), then the connection can be securely assembled, but the assembly process becomes complex and time-consuming
Solution Approach 1:
The patent combines the pipe, intermediate member, and locking device into a single integrated hose connection component. This merging eliminates the need for separate assembly steps while maintaining the secure connection function, directly resolving the contradiction between connection reliability and assembly complexity.
Solution Approach 2:
The integrated hose connection component performs multiple functions simultaneously: it provides the structural pipe connection, incorporates the intermediate member for sealing, and includes the locking device for securing. This multi-functionality reduces the number of parts while ensuring reliable assembly.
2Adaptability or versatility
If multiple hose connections are provided for different fuel hoses, then various fuel types can be dispensed, but the vapour recovery piping assembly becomes even more complicated
Solution Approach 1:
The hose connection component is designed with universal applicability for different fuel hose configurations. The integrated design allows the same component to be used across multiple fuel dispensing scenarios, and the vapour recovery ports are strategically positioned to simplify piping arrangements regardless of the number or type of fuel hoses connected.
3Ease of manufacture
If traditional hose connections use standard configurations, then assembly is straightforward, but blending of fuels with varying octane ratings within the hose connection is not possible
Solution Approach 1:
The hose connection component incorporates localized blending chambers or mixing zones within its structure. These specific regions are designed to facilitate fuel blending while the overall component maintains its straightforward assembly characteristics. The local quality modification enables fuel blending capability without compromising the ease of manufacture.
