Solution Overview

Problem

The existing methods for assembling radial adsorbers, particularly for large sizes, are cumbersome and costly due to the need for vertical assembly procedures that require extensive lifting equipment and workshops, limiting the construction of large adsorbers and increasing transportation and installation challenges.

Innovation Solution

A method for assembling radial adsorbers with concentric perforated grids in a horizontal position, using a support device with a rotating base and a lifting mechanism, allowing for horizontal welding and assembly, which facilitates the construction of larger adsorbers by minimizing deformation and deflection issues.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If vertical assembly procedures are used for large radial adsorbers, then the adsorbers can be assembled with proper structural integrity, but the construction becomes cumbersome and costly due to extensive lifting equipment and workshop requirements

Engineering Contradiction:
Improvestructural integrityVSAvoidconstruction complexity
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent inverts the traditional vertical assembly approach by implementing horizontal assembly of radial adsorbers. The adsorber is assembled in a horizontal position on a construction site, eliminating the need for extensive vertical lifting equipment and high workshop requirements. This inversion of the assembly orientation resolves the contradiction by maintaining structural integrity through proper horizontal welding and assembly procedures while dramatically reducing construction complexity and cost.

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The patent transitions from vertical (one-dimensional lifting) assembly to horizontal (multi-dimensional) assembly. By changing the assembly dimension from vertical to horizontal, the patent eliminates the need for extensive lifting equipment and reduces workshop height requirements, thereby resolving the contradiction between structural integrity and construction complexity.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Reliability

If vertical assembly procedures are used, then structural integrity can be maintained, but transportation and installation challenges increase due to the size and weight of the adsorber

Engineering Contradiction:
Improvestructural integrityVSAvoidtransportation and installation ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent inverts the traditional approach by assembling the adsorber horizontally rather than vertically. This allows the adsorber to be constructed in a more manageable orientation that reduces transportation and installation challenges, while still ensuring structural integrity through proper welding and assembly procedures in the horizontal position.

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The patent divides the assembly process into segments that can be handled and positioned more easily during horizontal assembly. The adsorber components are assembled in sections in a horizontal position, making transportation and installation more manageable while maintaining overall structural integrity through proper joining of segments.

Inventive Principle:
Principle #1Segmentation

3Ease of manufacture

If horizontal assembly is implemented, then construction costs and logistical challenges are reduced, but deformation and deflection issues may increase during assembly

Engineering Contradiction:
Improveconstruction costVSAvoiddeformation control
Core Design Contradiction:
Ease of manufactureVSManufacturing precision

Solution Approach 1:

The patent introduces temporary support structures and positioning devices as intermediaries during horizontal assembly. These intermediaries hold the adsorber components in the correct position and prevent deformation or deflection during the assembly process, thereby resolving the contradiction between reduced construction costs and maintained manufacturing precision.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent applies preliminary counter-actions during horizontal assembly by using support structures and positioning mechanisms that prevent deformation and deflection before they can occur. This preliminary anti-action ensures that the adsorber maintains proper dimensions and shape throughout the horizontal assembly process, resolving the contradiction between cost reduction and precision maintenance.

Inventive Principle:
Principle #9Preliminary anti-action
