Predimensioned Screen With Bonded Edge Pockets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing silk screening technologies face challenges in creating a flexible, pre-tensioned screen that can be easily rolled or folded for storage and shipping while maintaining integrity against fluid leakage and accidental damage.
Innovation Solution
The implementation of pockets along the screen's edges, secured with bonding material, allows for the insertion of tensioning rods to maintain tension and prevent fluid leakage and tearing, with a flexible seal that accommodates rolling and folding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the screen is made flexible to allow rolling or folding for shipping or storage, then the ease of operation and storage is improved, but the reliability and resistance to fluid leakage deteriorates
Solution Approach 1:
The patent applies this principle by using a flexible bonding material that forms a seal along the folded edge of the screen. The bonding material creates a flexible barrier that maintains fluid tightness while allowing the screen to be rolled or folded for storage and shipping, thus resolving the contradiction between flexibility for storage and reliability for fluid leakage prevention
Solution Approach 2:
The patent combines the screen fabric with a bonding material to create a composite structure. The bonding material forms both a structural pocket for tensioning rods and a flexible seal that prevents fluid leakage, enabling the screen to maintain reliability while being flexible enough for easy storage
2Adaptability or versatility
If pockets are formed along the edges to receive tensioning rods for retensioning, then the adaptability and ease of repair are improved, but the device complexity increases
Solution Approach 1:
The patent merges multiple functions into the bonding material: it bonds the folded edge to create structural integrity, forms a pocket to receive tensioning rods, and creates a flexible seal to prevent fluid leakage. This consolidation reduces device complexity while maintaining adaptability for retensioning
Solution Approach 2:
The bonding material serves multiple purposes: structural bonding, pocket formation, and fluid sealing. This multi-functionality allows the screen to be retensioned while avoiding the need for separate components, thus improving adaptability without significantly increasing device complexity
3Ease of operation
If a flexible seal is used to allow rolling and folding, then the ease of operation is improved, but the strength and resistance to tearing deteriorates
Solution Approach 1:
The bonding material forms a flexible seal that allows the screen to be rolled or folded while maintaining sufficient strength to prevent tearing. The flexible nature of the bonding material enables it to accommodate bending stresses without compromising the integrity of the screen edge
Solution Approach 2:
The combination of screen fabric and bonding material creates a composite edge structure that is both flexible and strong. The bonding material reinforces the folded edge, providing resistance to tearing while allowing the overall screen to remain flexible for storage
