Modular Curb Drain Insert for Contoured Concrete
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Contoured concrete curbs present a challenging surface for installing drainage pipes due to difficulty in drilling and are prone to damage from vehicular traffic, leading to pipe deterioration and cracking.
Innovation Solution
A modular curb drain insert with a molded body having planar surfaces and a contoured top surface that fits into a rectangular channel in the curb, featuring a horizontal bore for water conduction, made from durable materials like polymers or ceramics, which replaces traditional PVC pipes and eliminates the need for exposed concrete, providing a secure and durable drainage solution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a contoured concrete curb is used to prevent tire damage, then the curb provides a rounded protective surface, but the contoured surface becomes difficult to drill for installing drain pipes
Solution Approach 1:
The drain pipe installation is segmented from the main curb structure. A rectangular channel is cut into the contoured curb, creating a separate installation zone with a flat drilling surface while preserving the contoured outer surface for tire protection. The drain pipe is then installed within this segmented channel rather than directly into the contoured surface.
Solution Approach 2:
A rectangular channel acts as an intermediary structure between the contoured curb surface and the drain pipe. This channel provides a flat, accessible drilling surface while the contoured curb surface remains intact for its protective function. The channel mediates between the conflicting requirements of tire protection and pipe installation accessibility.
2Ease of operation
If a rectangular channel is cut into the contoured curb to install the drain pipe, then the drain pipe can be installed, but the exposed concrete and pipe become susceptible to damage from vehicular traffic
Solution Approach 1:
A modular insert made from durable polymer material is installed within the rectangular channel. This insert acts as a protective shell that encases the drain pipe connection area. The polymer material provides flexibility and impact resistance, protecting both the pipe and concrete from vehicular traffic damage while maintaining the drainage function.
Solution Approach 2:
The solution uses composite construction combining concrete (for structural strength), polymer materials (for flexibility and impact resistance), and sealing materials (for water tightness). The modular insert is made from polymer concrete or similar composite materials that combine the advantages of different materials to resist traffic damage while maintaining installation feasibility.
3Productivity
If traditional PVC pipes are exposed in the curb, then drainage function is provided, but the pipes are subject to damage from car tires and harsh weather
Solution Approach 1:
The drain pipe is enclosed within a protective polymer shell or insert that shields it from external damage. This flexible protective layer absorbs impact from tire contact and protects against harsh weather conditions while allowing the drainage function to operate normally through the enclosed pipe system.
Solution Approach 2:
The modular polymer insert provides beforehand cushioning protection for the drain pipe. By installing this protective element before the pipe is fully exposed to traffic and weather, the system pre-shields the vulnerable pipe sections from potential damage, extending the overall system reliability.

AI summary
A rectangular channel is cut into a contoured concrete curb along a street to expose an end of ground drain pipe. Sealing fill material is applied to portions of cut surfaces of the rectangular channel. A curb drain modular insert that is placed into the rectangular channel has a molded body that is formed to have a rear surface, bottom surface and lateral surfaces that are generally planar. The lateral surfaces are generally parallel to each other. Each lateral surface, rear surface and bottom surface being generally perpendicular to each other for being placed into the rectangular channel cut into the contoured curb. The molded body has a contoured top surface that conforms to portions of the contoured curb that are adjacent to the rectangular channel. A horizontal bore is formed in the molded body from the rear surface through the top surface to conduct ground water.
