Solution Overview

Problem

Drainage systems often leave standing water when fluid flow is low or nonexistent, creating ideal breeding grounds for mosquitoes and other hazards due to reptiles entering the system for repairs.

Innovation Solution

A fluid control system with a plug or flap gate that couples with a pipe's interior wall, blocking fluid flow until a certain flow threshold is reached, using a chain, string, or other material for coupling, and transitioning to allow flow when sufficient force is applied, preventing unwanted items from moving between pipes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a drainage system uses open pipes for fluid flow, then fluid can flow freely between pipes, but standing water remains when flow is low or nonexistent, creating mosquito breeding grounds and allowing reptile access

Engineering Contradiction:
Improvefluid flowVSAvoidmosquito breeding grounds and reptile access
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent employs a dynamic barrier device that automatically transitions between blocked and open states based on fluid flow conditions. The barrier remains closed to prevent mosquito breeding and reptile access during low or no flow conditions, and automatically opens when sufficient fluid flow is detected, allowing free drainage without manual intervention or fixed configuration

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The barrier device is self-actuating through buoyancy forces generated by the fluid flow itself. When fluid flows through the pipe, it creates buoyancy that automatically lifts the barrier to an open position, allowing the system to regulate its own state without external control mechanisms, sensors, or power sources

Inventive Principle:
Principle #25Self-service

2Object-affected harmful factors

If a barrier device is used to block pipe access, then reptile entry is prevented, but fluid flow may be restricted when not needed

Engineering Contradiction:
Improvereptile accessVSAvoidfluid flow
Core Design Contradiction:
Object-affected harmful factorsVSProductivity

Solution Approach 1:

The barrier device dynamically responds to fluid flow conditions, transitioning from a closed blocked state that prevents reptile entry to an open state that allows free fluid flow. The automatic transition is triggered by buoyancy forces when fluid flow reaches sufficient levels, ensuring the barrier only obstructs when necessary for safety

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The barrier device changes its positional state based on fluid flow parameters. When fluid flow rate or velocity exceeds a threshold, buoyancy forces cause the barrier to move from a blocked position to an open position, automatically adapting the system's flow restriction characteristic to current operating conditions

Inventive Principle:
Principle #35Parameter changes

3Object-affected harmful factors

If a plug or flap gate is used to control fluid flow, then mosquito breeding is prevented, but the device complexity increases with coupling mechanisms

Engineering Contradiction:
Improvemosquito breeding groundsVSAvoidcoupling mechanism
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The coupling mechanism is eliminated by making the barrier device self-actuating through buoyancy forces. The barrier automatically couples with and blocks the aperture without requiring chains, strings, tapes, chords, wires, or ropes. The fluid flow itself provides the actuating force, simplifying the device while maintaining effective mosquito prevention

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent removes complex coupling mechanisms from the system by using a buoyancy-based self-actuating barrier. The harmful element (complex coupling) is extracted and replaced with a simpler direct-acting barrier that uses fluid buoyancy for automatic operation, reducing device complexity while maintaining functionality

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

A fluid control system to control fluid flow within a drainage system is disclosed that includes a cage configured to couple an interior wall of a structure of the drainage system, wherein the cage at least partially surrounds an aperture of the interior wall, and a float device configured to be encapsulated within the cage, wherein while in a resting state, the float device at least partially covers an aperture of the structure of the drainage system. In some instances, when fluid contacts the float device at a flow rate of at least a flow threshold, the float device is configured to at least partially uncover the aperture of the interior wall, or further uncover the aperture of the interior wall. The float device may be formed from a buoyant material and configured to rise from the resting state in accordance with a rising fluid level within the structure.
