Solution Overview

Problem

Existing separator tanks with external lifting mechanisms require additional space due to their footprint, leading to inefficiencies in space utilization and increased costs in compressor installations.

Innovation Solution

A lifting mechanism that includes a pin inserted into a tank body flange extending through the sealing plate, with a threaded device that applies a pushing force to lift the sealing plate, allowing it to pivot out of the way without increasing the tank's footprint.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If an external lifting structure is attached to the tank sidewall, then the sealing plate can be lifted and pivoted out of the way to access the tank interior, but the footprint of the tank is increased requiring more free space

Engineering Contradiction:
Improveaccess to tank interiorVSAvoidtank footprint
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

The lifting mechanism is merged with the tank body by integrating the pin and threaded device directly into the tank structure rather than attaching them externally. The pin is inserted into the tank body and the threaded device is integrated into the sealing plate, combining the lifting function with the existing tank components to eliminate the need for external lifting structures.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The lifting mechanism components are nested within the tank structure. The pin is inserted into the tank body and extends through the sealing plate, while the threaded device is integrated into the sealing plate itself. This nesting arrangement allows the lifting mechanism to be contained within the tank's existing footprint without requiring additional external space.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Ease of operation

If an external lifting structure is used, then the sealing plate can be removed, but additional space is required purely for the lifting mechanism

Engineering Contradiction:
Improvesealing plate removalVSAvoidspace utilization
Core Design Contradiction:
Ease of operationVSQuantity of substance

Solution Approach 1:

The lifting mechanism is combined with the tank body and sealing plate components, eliminating the need for separate external lifting structures. The pin is integrated into the tank body and the threaded device is integrated into the sealing plate, merging the lifting function with the existing components to maximize space utilization.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The pin and threaded device serve multiple functions: the pin provides both structural support and a lifting fulcrum, while the threaded device provides both sealing and lifting functions. This multi-functionality eliminates the need for dedicated external lifting structures, thereby improving space utilization.

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

3Ease of operation

If a threaded device is inserted into the sealing plate, then rotation of the threaded device translates into vertical movement to lift the sealing plate, but the device complexity increases

Engineering Contradiction:
Improvesealing plate liftingVSAvoidlifting mechanism structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The threaded device is self-contained and self-operating. When rotated, it automatically translates its own rotation into vertical movement through its threaded engagement with the pin, lifting the sealing plate without requiring additional control mechanisms or external power sources. This self-service characteristic simplifies the overall device complexity.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The complex mechanical lifting system is replaced with a simple threaded mechanism. Instead of using hydraulic cylinders, electric motors, or complex linkage systems, the invention uses a straightforward threaded device that converts rotational motion into linear motion through basic mechanical threading, thereby reducing device complexity.

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

AI summary

A tank having a sealing plate and a tank body and lifting mechanism for separating the sealing plate from the tank body of a tank are provided. The lifting mechanism includes a pin inserted into a flange of the tank body extending through the sealing plate, and a threaded device coupled to the sealing plate and selectively contacting the pin to apply a pushing force in response to the threaded device being inserted into the sealing plate.
