Solution Overview

Problem

Existing tank arrangements can only be vented when full and emptied at a limited speed, as they require a free-flowing medium for venting and have restricted drainage capabilities.

Innovation Solution

A tank arrangement with an air inlet device that allows air to be supplied to the tank, enabling venting even when empty and facilitating faster drainage through the use of a valve system that converts the inlet into an outlet and includes a connection for compressed air, allowing for enhanced flow control and pressure management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a tank uses only outlet valves for draining and pressure release, then the structure is simple, but the tank can only be vented when full and emptying speed is limited

Engineering Contradiction:
Improveemptying speedVSAvoidventing capability
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The air inlet device is designed to serve multiple functions: it can supply air to accelerate emptying when the tank is full, enable venting when the tank is empty, and provide flushing capability. This multi-functional design resolves the contradiction by allowing the same device structure to achieve both fast emptying and empty-state venting without requiring separate complex systems for each function.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Speed

If air is supplied to accelerate emptying, then emptying speed increases, but the tank requires a free-flowing medium which is not available when empty

Engineering Contradiction:
Improvedrainage rateVSAvoidventing at any state
Core Design Contradiction:
SpeedVSAdaptability or versatility

Solution Approach 1:

The system dynamically adapts its function based on the tank's state. When the tank is full, the air inlet device supplies air to accelerate drainage. When the tank is empty, the same device enables venting of built-up pressure. This dynamic adaptability resolves the contradiction by allowing the system to optimize performance for different operational states using the same hardware infrastructure.

Inventive Principle:
Principle #15Dynamics

3Productivity

If compressed air connection is added for faster emptying, then productivity increases, but the device complexity and storage risks increase

Engineering Contradiction:
Improveemptying speedVSAvoidpressure buildup risk
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The air inlet device with valve provides controlled feedback management for pressure. The valve allows operators to regulate air supply to accelerate emptying while also serving as a pressure relief mechanism. This feedback control resolves the contradiction by enabling fast emptying when needed while providing a controlled pathway to manage and release built-up pressure, reducing storage risks.

Inventive Principle:
Principle #23Feedback

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Enables efficient venting and drainage of tanks at any state, including when empty, and allows for quicker emptying and flushing, while also managing pressure and reducing storage risks by dissipating built-up pressure through the air inlet valve.

Implementation Method 1

a tank arrangement with an air inlet device, as a result of which air can be supplied to the interior of a tank. In this way, the tank can be vented and the flow rate of the drain can be controlled

Methodology Applied
Scientific EffectAir pressure: Pressure Increase

Implementation Method 2

an outlet to remove a medium from the tank, the outlet having a valve device which can be opened manually via a lever

Methodology Applied
Scientific EffectValve flow control: Valve
