Debris Cage Panel Design for Pipe Inlet Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drainage and irrigation pipe protection systems fail to effectively prevent debris from entering pipes while allowing fluid flow, and they do not adequately protect against accidental human entry, particularly for children, due to their design limitations and safety hazards.
Innovation Solution
A debris cage composed of multiple panels with variously sized and shaped openings is designed to form a cylindrical or conical structure, which can be fastened together to enclose the pipe opening, allowing fluid flow while impeding debris and enhancing safety by preventing human entry.

Engineering Contradiction Analysis
1Object-affected harmful factors
If a fence structure with flexible mesh or screen material is used to protect the open upper end of the pipe inlet, then the structure provides some debris protection, but it fails to effectively prevent debris from entering the pipe and provides little or no protection against persons inadvertently falling into the inlet
Solution Approach 1:
The protective structure is divided into multiple rigid panels that are fastened together to form a cage-like enclosure. Each panel can be independently manufactured and assembled, allowing for modular construction that maintains structural integrity while providing effective debris and personnel protection.
Solution Approach 2:
The protective device combines rigid panel materials with secure fastening mechanisms to create a composite structure that is both structurally sound and难以 penetrable by debris or persons, significantly improving upon the single-material flexible mesh approach.
2Productivity
If the pipe opening is left open to facilitate fluid flow, then water flow is unrestricted, but debris can easily enter and clog the pipe requiring frequent manual cleaning
Solution Approach 1:
The rigid panels incorporate openings or perforations that allow water and small particles to pass through freely while blocking larger debris. This porous design maintains fluid flow efficiency while preventing clogging, reducing the need for frequent manual cleaning operations.
Solution Approach 2:
The protective device acts as an intermediary structure between the open environment and the pipe inlet, filtering debris before it can enter the pipe while maintaining unrestricted water flow through its strategically designed openings.
3Ease of repair
If manual cleaning operations are performed in cramped pipe conditions, then debris can be removed, but the operation is difficult to maneuver and creates danger of cave-ins or collapse
Solution Approach 1:
The protective device is installed in advance to prevent debris accumulation in the first place, eliminating the need for subsequent manual cleaning operations in hazardous confined spaces. This preliminary protective measure addresses the root cause rather than treating symptoms later.
Solution Approach 2:
The device transforms the potential harm of debris entry and subsequent dangerous cleaning operations into a beneficial situation where debris is blocked externally, allowing cleaning to be performed safely on the device itself rather than inside the hazardous pipe environment.
4Ease of operation
If the open end of the inlet is left exposed, then access is easy, but the deep drop-off creates severe injury risk for persons who might inadvertently fall in
Solution Approach 1:
The protective cage structure is installed in advance to prevent the harmful action of persons falling into the open inlet. The rigid panels create a physical barrier that stops potential fallers before they can reach the dangerous drop-off, while still allowing legitimate access when needed.

AI summary
A debris cage is disclosed. The debris cage may include multiple panels, each having a plurality of opening. Each of the panels may be fastened together to form an enclosed structure having a substantially cylindrical portion integral with a conical or dome-like portion at a terminating end of the enclosed structure. Each of the panels may have various shaped openings facilitating the flow of fluid while potentially impeding debris from passing through the debris cage.
