Fuel Dispenser Nozzle Boot with Integrated Hose Guide
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fuel dispensing units have bulky and complicated hose returning mechanisms and guiding means, leading to large and inefficient designs that hinder space utilization and ease of use, particularly when the vehicle is parked at an angle or distance from the pump.
Innovation Solution
A nozzle boot arrangement positioned between two vertical profiles in the fuel dispensing unit, with a hose guiding means attached to the nozzle boot, allowing for efficient hose extraction and storage without lateral displacement, and enabling a more compact and cost-effective design by integrating the guiding mechanism with the nozzle boot and using a roller for hose management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional hose returning mechanism with guiding means is used, then the hose can be properly guided and stored, but the structure becomes bulky and complicated, increasing the overall size of the fuel dispensing unit
Solution Approach 1:
The patent combines the hose guiding means with the nozzle boot assembly, integrating two separate components into one unified structure. The guiding means is positioned at the rear end of the nozzle boot, allowing the hose to be guided directly through the nozzle boot assembly itself, eliminating the need for separate guiding mechanisms and reducing overall structural complexity.
Solution Approach 2:
The patent positions the hose guiding means in a vertical arrangement above the nozzle boot, utilizing the vertical dimension to route the hose. This vertical positioning allows the hose to be guided through the nozzle boot assembly without requiring additional horizontal space, thereby reducing the overall footprint and avoiding bulky lateral structures.
2Area of stationary object
If the nozzle boot is positioned at the front side between vertical profiles, then space for hose handling means is provided and the unit width is reduced, but the hose extraction path becomes more constrained
Solution Approach 1:
The patent utilizes the vertical dimension to resolve the space constraint. By positioning the hose guiding means vertically above the nozzle boot and routing the hose through this vertical path, the system achieves compact horizontal footprint while maintaining adequate hose extraction capability. The vertical arrangement provides sufficient space for hose handling without requiring additional horizontal width.
3Ease of manufacture
If the hose guiding means is attached to the nozzle boot, then manufacturing complexity is reduced and cost is lowered, but the guiding precision may be compromised
Solution Approach 1:
The patent integrates the hose guiding means with the nozzle boot assembly, combining two components into one unified structure. This integration simplifies manufacturing by reducing the number of separate parts and assembly steps, while the precise positioning of the guiding means at the rear end of the nozzle boot ensures accurate hose routing without compromising guiding precision.
