Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gas-liquid contact packings face challenges such as increased manufacturing costs, weight, and energy inefficiency due to structural weaknesses and complex gas flow paths, which lead to deformation, pressure loss, and reduced gas-liquid contact areas.
Innovation Solution
A packing design featuring sheet materials arranged in parallel with strategically positioned support members, including pair of support walls and bridging parts, to form a sandwiching structure that maintains the sheet materials' integrity and reduces pressure loss while allowing efficient gas flow and liquid distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If net-like bodies or three-dimensional knitted fabrics are used as packing materials to increase gas-liquid contact area, then the contact area is improved, but the structural strength decreases causing deformation and requiring additional support members that increase weight
Solution Approach 1:
The packing is divided into multiple sheet materials arranged in parallel, each sheet being a separate structural unit. This segmentation allows each sheet to maintain structural integrity independently while collectively providing large gas-liquid contact area, resolving the contradiction between contact area and structural strength
Solution Approach 2:
Each sheet material is constructed as a composite structure combining a base sheet with an integrated rib pattern. The ribs are formed as integral parts of the sheet material, creating a composite structure that simultaneously provides structural support and maintains large contact area for gas-liquid interaction
2Weight of moving object
If sheet materials are arranged in parallel to reduce weight and manufacturing cost, then weight and cost are reduced, but the sheet materials deform and deflect under load
Solution Approach 1:
The continuous sheet material is segmented into multiple sections by integrating ribs at specific intervals. This segmentation creates smaller, more stable structural units that resist deformation individually, allowing the overall packing to remain lightweight while maintaining stability
Solution Approach 2:
Ribs are strategically positioned at specific locations on each sheet material where structural support is most needed. This local reinforcement approach provides stability exactly where required without adding unnecessary weight across the entire sheet, maintaining the lightweight advantage while preventing deformation
3Area of stationary object
If complex-shaped packing materials are used to increase gas-liquid contact area, then contact area is improved, but gas flow resistance increases causing pressure loss and energy inefficiency
Solution Approach 1:
The packing is segmented into multiple flat sheet materials arranged in parallel rather than using complex three-dimensional structures. This segmentation creates straight, unobstructed gas flow paths between the sheets, reducing flow resistance and pressure loss while the multiple sheets collectively provide large contact area
Solution Approach 2:
Instead of increasing contact area by creating complex three-dimensional shapes that obstruct flow, the invention uses multiple two-dimensional sheets arranged in parallel. This dimensional approach provides large total contact area while maintaining simple, straight gas flow paths, thereby reducing pressure loss and energy consumption

AI summary
A packing has a plurality of sheet materials spaced and arranged in parallel, and is used in a standing state to cause liquid to flow along the flat surface thereof. Each sheet material has at least one member group including a plurality of support members arranged such that the upper end of the uppermost support member corresponds to the upper end of the sheet material and the lower end of the lowermost support member corresponds to the lower end of the sheet material. Each support member has a pair of support walls parallel to the liquid flow direction and perpendicular to the flat surface of the sheet material, and a bridging part connecting the support walls . Formed is a sandwiching structure that one sheet material is held by at least one support member attached thereto and at least one support member attached to an adjacent sheet material, and the sandwiching structure extends linearly through the plurality of sheet materials.
