Fuel Pump Island Repair Wrap With Preformed Band Sections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high cost and downtime associated with traditional methods of repairing fuel pump islands due to concrete and metal band degradation, requiring extensive demolition and reconstruction, necessitate an improved repair system.
Innovation Solution
A method and system utilizing preformed band pieces, including straight, outside corner, and inside corner band pieces made of corrosion-resistant metal, attached to the fuel pump island using fasteners, allowing for on-site installation without removing existing fuel pumps, and finishing the top surface to create a seamless repair.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional repair methods are used to replace damaged concrete and metal bands, then structural integrity is restored, but repair costs and downtime increase significantly
Solution Approach 1:
The replacement band system is divided into multiple preformed band pieces (straight pieces, outside corner pieces, inside corner pieces) that can be independently manufactured, transported, and installed. This segmentation allows for modular replacement without requiring complete demolition of the fuel pump island structure.
Solution Approach 2:
The band pieces are preformed and prepared before installation, including pre-attaching corner pieces to straight pieces where appropriate. This preliminary preparation reduces on-site construction time and eliminates the need for complex field fabrication, thereby reducing repair downtime while maintaining structural integrity.
2Reliability
If traditional repair methods are used to replace damaged concrete and metal bands, then structural integrity is restored, but repair costs increase
Solution Approach 1:
By segmenting the replacement band into standardized preformed pieces, the system enables efficient manufacturing and inventory management. Damaged sections can be replaced piece-by-piece rather than requiring complete island reconstruction, significantly reducing material and labor costs while maintaining structural integrity.
Solution Approach 2:
The system allows for selective replacement of only the damaged band portions while preserving the intact concrete base and fuel pump infrastructure. This partial replacement approach recovers valuable existing structures and reduces waste, lowering overall repair costs compared to complete replacement.
3Loss of time
If preformed band pieces are used for repair, then repair time and cost are reduced, but installation complexity increases
Solution Approach 1:
The segmented preformed band pieces are designed with standardized connection methods (fasteners, welding, or mechanical interlocks) that simplify assembly. Each piece is independently manufacturable and can be installed in a systematic sequence, reducing overall installation complexity despite the modular nature of the system.
Solution Approach 2:
Corner pieces are pre-attached to straight pieces where appropriate, merging multiple components into integrated assemblies before installation. This reduces the number of separate connection operations required on-site and simplifies the installation process while maintaining the benefits of modular segmentation.

AI summary
A method for repairing a damaged band of a fuel pump island, comprising: selecting among preformed band pieces to form a replacement band system for the fuel pump island, wherein the preformed band pieces include one or more of a straight band piece for covering a straight portion of a vertical wall of the fuel pump island, an outside corner band piece for covering an outside corner portion of the vertical wall of the fuel pump island, and an inside corner band piece for covering an inside corner portion of the vertical wall of the fuel pump island; preparing the fuel pump island by removing debris from the vertical wall and a top surface of the fuel pump island; installing the replacement band system over the damaged band of the fuel pump island by attaching respective wall portions of the preformed band pieces to the vertical wall of the fuel pump island; and, finishing a top surface of the fuel pump island to at least a height that is level with top surfaces of respective flange portions of the preformed band pieces.
