Solution Overview

Problem

Existing gully systems face issues such as ice formation due to rising gases/heat, air intake that disrupts vacuum gully operation, complexity in design and calculation, blockages from debris, and sensitivity to structural changes, which affect drainage efficiency and require frequent adjustments and flushing.

Innovation Solution

An adjustable float system that prevents gases/heat from rising and entering the gully, acting as an automatic air lock and throttle, controlled by sensors and a central unit to maintain optimal drainage and prevent ice buildup, allowing for adjustable gully heights and connection to a common outlet system.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a vacuum gully system is used to improve drainage efficiency, then drainage capacity is improved, but the system becomes sensitive to structural changes and requires frequent adjustments

Engineering Contradiction:
Improvedrainage capacityVSAvoidsensitivity to structural changes
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent employs dynamically adjustable components including variable speed pumps and controllable valves that can adapt to changing structural conditions. The system includes sensors that detect structural changes and automatically adjust operational parameters to maintain optimal drainage performance without requiring manual recalibration.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system allows dynamic modification of operational parameters such as pump speed, valve opening degree, and pressure settings in response to structural changes. This enables the vacuum gully system to maintain its high drainage capacity even when building structures or outlet configurations are modified.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If throttle disks are used to adapt gullies to different water amounts, then adaptability is improved, but the gully head becomes easily blocked by extraneous matters

Engineering Contradiction:
Improveadaptability to water amountsVSAvoidblockage resistance
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent introduces an intermediary filtering mechanism that separates the flow regulation function from the throttling function. A removable filter screen is positioned upstream of the throttle disk to intercept extraneous matters before they reach the throttling mechanism, preventing blockages while maintaining adaptability through electronic flow control.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system replaces manual mechanical adjustment of throttle disks with electronically controlled actuators and variable speed pumps. This eliminates the need for physical throttle disk adjustment and reduces blockage risks through automated control systems that can detect and respond to flow restrictions.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Ease of manufacture

If outlet pipes are arranged horizontally to minimize ground piping, then installation complexity is reduced, but the system becomes sensitive to changes in water amounts

Engineering Contradiction:
Improveinstallation simplicityVSAvoidsensitivity to water amount changes
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent incorporates flow sensors and level detectors that provide continuous feedback to the control system. When water amounts change, the system automatically adjusts pump speed and valve positioning to maintain proper flow conditions, compensating for the lack of gravitational assistance from sloped piping.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system includes self-regulating components such as float valves and automatic air release valves that maintain optimal operation without external intervention. The control system automatically responds to water amount changes, eliminating the need for manual adjustments or complex piping slopes.

Inventive Principle:
Principle #25Self-service

AI summary

An object of the present invention is to provide a system and a method for effectively preventing that gases/heat from an outlet are ascending from a gully and form ice, in addition to effectively drain liquids through a gully. The present invention is obtained by arranging a float so that said float and a portion of the gully define a closable opening for through flow, further arranged such that the float is preventing gases/heat from the outlet to ascend up from the gully and form ice and/or so that the float prevents that gas is drawn into the gully.
