Patterned Adhesive Tape for Dustproof Ventilation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing tapes for closing openings in a dustproof yet ventilating manner require an additional process step for arranging patterns, increasing the cost price due to additional manufacturing complexity.
Innovation Solution
A tape with a glue layer that completely closes the open pore structure locally, arranged in accordance with the pattern on the rear side of the elongate fabric strip, serving as both an adhesive for fixation and a ventilation controller, eliminating the need for extra processing steps, and optionally incorporating anti-algal and anti-fungal agents or copper-containing compounds for enhanced durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a separate pattern layer is arranged mechanically or through coating to control ventilation, then ventilation can be precisely regulated, but an additional process step is required increasing manufacturing cost
Solution Approach 1:
The patent combines the adhesive layer and the ventilation-controlling pattern layer into a single integrated glue layer. The glue layer is applied in a pattern that simultaneously provides adhesion at edges and seals pores in intermediate areas to control ventilation, eliminating the need for a separate pattern layer and reducing manufacturing complexity.
Solution Approach 2:
The glue layer serves multiple functions: it acts as an adhesive for fixing the tape at the edges, and simultaneously functions as a ventilation control mechanism by sealing pores in the intermediate areas through its patterned application. This multi-functionality eliminates the need for separate components.
2Reliability
If a pattern layer is added to control ventilation, then dustproof performance is improved, but manufacturing cost increases due to additional processing
Solution Approach 1:
The adhesive layer and the dustproof pattern layer are merged into a single glue layer. The patterned application of this layer simultaneously provides both adhesion and dustproof sealing, eliminating the need for additional processing steps and reducing manufacturing cost.
Solution Approach 2:
The glue layer automatically serves dual purposes: adhering the tape to the substrate at the edges and sealing the pores in the intermediate areas to provide dustproof performance. The same material and application process achieve both functions without requiring additional services or components.
3Strength
If the glue layer is applied in a dense pattern for adhesion, then adhesive strength is improved, but ventilation control capability is reduced
Solution Approach 1:
The glue layer is applied with different densities in different areas: a dense pattern at the edges for strong adhesion, and a sparser pattern in the intermediate areas for effective pore sealing while maintaining ventilation control. This local variation in quality optimizes both adhesive strength and ventilation control.
Solution Approach 2:
The glue layer pattern is segmented into different regions with different densities - edge regions with high density for adhesion and intermediate regions with lower density for ventilation control. This segmentation allows each region to fulfill its specific function optimally.
