Solution Overview

Problem

Industrial tanks, particularly Large Bulk Containers (IBCs) in the chemical and petroleum industries, often retain significant amounts of chemical products due to their configuration and drain valve location, leading to incomplete emptying and increased costs for treatment and recycling, with existing solutions failing to achieve complete drainage without manual intervention.

Innovation Solution

A tank support device with a movable element that pivots around an axis of rotation, utilizing elastic means to tilt the tank when the remaining product weight falls below a threshold, directing the drain valve towards the remaining fluid for more complete emptying, minimizing operator intervention and environmental impact.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If the tank is placed flat on its support, then the tank is stable and easy to handle, but the tank cannot empty completely and retains 5-10% of product

Engineering Contradiction:
Improveproduct retentionVSAvoidautomatic emptying
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The support device transforms from a static horizontal position to a dynamic tilted position automatically. When the tank weight decreases below a threshold (indicating near-empty state), the mobile support element pivots around an axis of rotation, causing the tank to tilt and directing remaining product toward the drain valve for complete emptying.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system uses the tank's own weight as the triggering mechanism. As product drains and weight decreases, the elastic means (spring) automatically activates the tilting motion without external intervention, allowing the system to self-regulate and achieve complete emptying based on its own operational state.

Inventive Principle:
Principle #25Self-service

2Quantity of substance

If manual intervention is used to empty the tank completely, then product retention is reduced, but operator intervention and treatment costs increase

Engineering Contradiction:
Improveproduct retentionVSAvoidautomatic emptying
Core Design Contradiction:
Quantity of substanceVSExtent of automation

Solution Approach 1:

The support device autonomously detects when the tank is near-empty through weight measurement and automatically initiates the tilting emptying sequence. This eliminates the need for operator intervention while achieving complete product removal, as the system serves itself by using its own weight change as the trigger signal.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system incorporates a weight measurement mechanism that provides feedback on the tank's current state. When the weight falls below a predetermined threshold, this feedback triggers the automatic tilting action, creating a closed-loop control system that ensures complete emptying without manual input.

Inventive Principle:
Principle #23Feedback

3Quantity of substance

If the tank is tilted to empty completely, then product retention is minimized, but the tank structure and support complexity increase

Engineering Contradiction:
Improveproduct retentionVSAvoidsupport structure
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

Rather than a permanently complex tilted structure, the invention uses a dynamic system where a mobile support element pivots only when needed. The majority of the time, the tank remains on a simple horizontal support. The complexity is activated temporarily and automatically only during the final emptying phase, minimizing overall structural complexity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The support system is divided into a fixed horizontal support element and a mobile tilting support element that pivots independently. This segmentation allows the simple fixed support to handle normal operation while the mobile element provides the tilting function only when weight threshold is reached, reducing overall system complexity.

Inventive Principle:
Principle #1Segmentation
