Fuel Dispenser Conversion Frame for Leak Drainage and Anchoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional conversion frames for fuel dispensers are custom-fabricated, time-consuming, and costly due to size disparities between new fuel dispensers and existing under dispenser containment units, and lack anchoring, posing safety hazards.
Innovation Solution
A conversion frame assembly with a base plate and drainage tray that secures the fuel dispenser to the concrete pad, directing leaked fuel into an embedded sump, featuring a fluid passageway, splash lip, and adjustable openings for anchoring, and a method to retrofit existing sums for compatibility with new dispensers of varying sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional conversion frames are custom fabricated for each dispenser model, then the containment effectiveness is improved, but the installation time and cost increase
Solution Approach 1:
The conversion frame is designed with a universal base plate that can be adapted to multiple dispenser models through adjustable components. The base plate includes multiple mounting hole patterns and adjustable support legs that can accommodate different footprint configurations, eliminating the need for custom fabrication for each dispenser model while maintaining containment effectiveness.
Solution Approach 2:
The conversion frame incorporates adjustable support legs and movable mounting components that can be repositioned to match different dispenser configurations. This dynamic adjustability allows a single frame design to fit various dispenser models without requiring custom fabrication, thereby reducing installation time while preserving containment reliability.
2Manufacturing precision
If conventional conversion frames are custom fabricated, then the fit precision is improved, but the manufacturing complexity increases
Solution Approach 1:
The conversion frame is divided into modular components including a base plate, support legs, and mounting brackets. Each component is designed with standardized dimensions and interchangeable parts that can be assembled in different configurations. This segmentation allows for precise fitting through simple assembly rather than complex custom fabrication, reducing manufacturing complexity while maintaining fit precision.
Solution Approach 2:
The conversion frame utilizes adjustable parameters such as leg lengths, mounting hole positions, and bracket angles that can be modified to match different dispenser configurations. These parameter adjustments enable precise fitting without requiring custom fabrication for each model, thereby maintaining manufacturing simplicity while achieving high fit precision.
3Ease of operation
If the fuel dispenser is not anchored to the concrete pad, then the installation simplicity is improved, but the safety decreases
Solution Approach 1:
The conversion frame includes a base plate with pre-configured anchor points and mounting hardware that is prepared in advance for secure attachment to the concrete pad. The anchor bolts and structural connections are designed to be installed using standard procedures, providing safety through preliminary preparation without significantly complicating the installation process.
4Reliability
If the conversion frame is anchored to the concrete pad, then the safety is improved, but the installation complexity increases
Solution Approach 1:
The conversion frame incorporates self-aligning features and pre-drilled anchor points that facilitate straightforward attachment to the concrete pad. The base plate design includes built-in guidance features that automatically position the anchor bolts correctly, eliminating the need for complex alignment procedures and reducing installation complexity while ensuring safe anchoring.

AI summary
A conversion frame assembly configured to secure a fuel dispenser to a concrete pad and direct leaked fuel from the fuel dispenser into a sump at least partially embedded in the concrete pad. The conversion frame assembly includes a frame having a fluid passageway and a splash lip extending upward from the base plate and around the fluid passageway. The conversion frame assembly also includes a drainage tray configured to be coupled to the splash lip of the frame. When the drainage tray is coupled to the splash lip of the frame, an upper surface of the drainage tray defines a weir sloping inward and downward toward the fluid passageway in the base plate.
