Recycled Plastic Bridging Modules for Biofilter Floor Integrity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Biofiltration systems face challenges in maintaining continuity and integrity across air delivery trenches due to the lack of durable and structurally secure bridging elements, with existing solutions like stainless steel corroding quickly and molded plastic being insufficient in strength and interconnection.
Innovation Solution
The development of high-strength, recycled plastic bridging modules that interlock with floor tile assemblies on both sides of the trench, featuring alternating orientations and secure connections to ensure a level and uniform surface, with each module acting as a structural beam to support high loads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If stainless steel bridging elements are used, then structural strength is provided, but they corrode quickly due to the corrosive nature of the gases
Solution Approach 1:
The patent employs composite construction by integrating reinforcing ribs within the plastic bridging module. The module combines plastic material with structural reinforcement elements, creating a composite structure that maintains strength while resisting corrosion. This resolves the contradiction by providing structural integrity through the composite design rather than relying on corrosive metal materials.
Solution Approach 2:
The patent replaces expensive, short-lived stainless steel components with durable, corrosion-resistant plastic modules. Although plastic may seem weaker, the modular design with reinforcing ribs creates a long-lasting solution that doesn't corrode, effectively replacing the 'cheap short-living' approach with a durable alternative that eliminates the corrosion problem entirely.
2Reliability
If molded plastic bridging elements are used, then corrosion resistance is improved, but they lack adequate strength and durability
Solution Approach 1:
The patent resolves this contradiction by creating a composite plastic structure with integrated reinforcing ribs. The combination of plastic material and structural reinforcement creates a composite bridging module that achieves both corrosion resistance and adequate structural strength, eliminating the weakness of simple molded plastic while maintaining the corrosion-free advantage.
Solution Approach 2:
The bridging module is segmented into functional zones: the main plastic body providing corrosion resistance and the integrated reinforcing ribs providing structural strength. This segmentation allows each part to fulfill its specific function, with the ribs strategically positioned to provide support where needed while the plastic material maintains corrosion resistance throughout.
3Ease of manufacture
If molded plastic bridging elements are used, then ease of manufacture is improved, but they lack adequate interconnection with floor tile assemblies
Solution Approach 1:
The patent merges the bridging function with the connection function into a single integrated module. The bridging module incorporates features for both spanning the trench and securely interlocking with floor tile assemblies, eliminating the need for separate connection components and ensuring reliable interconnection while maintaining ease of manufacture through a unified molded design.
Solution Approach 2:
The integrated design combines multiple functional elements into a composite molded structure that provides both structural bridging and secure connection capabilities. This composite approach ensures that the connection features are as durable and reliable as the bridging structure itself, while maintaining the manufacturing advantages of a single molded component.
4Productivity
If the floor tile system is interrupted by trenches, then air delivery is enabled, but continuity of the floor system is lost
Solution Approach 1:
The bridging module serves as an intermediary element that spans across the air delivery trench, maintaining the continuity of the floor system while allowing the trench to remain open for air delivery. This mediator component connects the floor tiles on either side of the trench, ensuring structural continuity without compromising the air delivery function of the trench.
Solution Approach 2:
The bridging module extends in the horizontal dimension across the trench, creating a span that maintains floor continuity. By adding this dimensional element, the system preserves the vertical air delivery pathway through the trench while establishing horizontal continuity across it, effectively resolving the contradiction through spatial arrangement.

AI summary
A modular biofiltration support system for a bed of organic filter medium, formed of a multiplicity of rectangular bed platform modules or floor tiles, provides for bridging across an air/gas supply trench which can be up to 36 inches or even 48 inches wide. The bridging sections, formed of a mix of recycled plastic materials in a high-pressure molding operation, interconnect with edges of the floor tile assemblies on each side of the trench, and also engage with one another at sides. Each module is a high strength beam.
