Fiber Laminate With Linear Adhesive Pattern For Dust Filtration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fiber laminates with adhesive application face challenges in balancing dust collection efficiency and pressure loss, where insufficient adhesive leads to peeling and excessive adhesive worsens ventilation, preventing optimal dust collection.
Innovation Solution
A fiber laminate design featuring a first fiber sheet, a second fiber sheet, and an adhesive applied in a linear pattern, creating a gap between the sheets to reduce pressure loss and enhance dust collection efficiency, with the adhesive forming a linear region for bonding and gaps for increased surface area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If adhesive is applied extensively to prevent peeling, then bonding strength is improved, but pressure loss increases and ventilation deteriorates
Solution Approach 1:
The adhesive application area is segmented into discrete linear patterns rather than continuous coverage. The adhesive forms linear regions that segment the bonding interface, providing sufficient adhesion at key locations while leaving gaps that maintain ventilation and reduce pressure loss.
Solution Approach 2:
Adhesive is applied locally at specific linear patterns rather than uniformly across the entire surface. This local quality approach concentrates bonding strength where needed while maintaining gaps in other regions to preserve ventilation performance and reduce pressure loss.
2Loss of energy
If adhesive amount is reduced to improve ventilation, then pressure loss is suppressed, but peeling occurs between sheets
Solution Approach 1:
The adhesive is distributed through segmented linear patterns that provide discrete bonding points. This segmentation allows sufficient adhesive to prevent peeling at critical interfaces while maintaining overall ventilation by avoiding continuous adhesive coverage.
Solution Approach 2:
Instead of applying adhesive to the entire surface (excessive action), the linear pattern applies adhesive only to necessary regions (partial action). This partial application provides just enough bonding strength to prevent peeling while avoiding the excessive adhesive that would cause pressure loss.
3Productivity
If adhesive is applied in linear pattern to create gaps, then dust collection efficiency is improved, but bonding area is reduced
Solution Approach 1:
The linear adhesive patterns create local bonding regions that are strategically positioned to maintain structural integrity while generating gaps for dust collection. The bonding area is concentrated where needed to prevent peeling, while gaps are created in regions that enhance dust collection efficiency.

Function Achieved in This Case
This configuration effectively suppresses pressure loss while increasing dust collection efficiency by allowing a smaller adhesive amount and promoting a wavy shape for higher surface area, thus improving filtration performance.

AI summary
A fiber laminate includes a first fiber sheet containing first fibers, a second fiber sheet laminated on the first fiber sheet and containing second fibers, and an adhesive interposed between the first fiber sheet and the second fiber sheet. The adhesive is disposed to form a linear first region in the fiber laminate when viewed from a normal direction of a principal surface of the fiber laminate. The first fiber sheet and the second fiber sheet are adhered to each other via the first region. A gap is formed between the first fiber sheet and the second fiber sheet in a second region other than the first region.
