V-Section Slide Seal Design for Sliding Closure Durability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing closure devices face issues with complex and costly seal designs, elastic brush seals that degrade over time, and adhesive fastening systems prone to damage from stress and environmental factors, leading to reduced durability and increased maintenance needs.
Innovation Solution
A slide seal with a 'V' section elongated element featuring a base and lip, made of deformable material, integrated into a profile with 'U' section housings, which simplifies design and manufacturing, enhances durability, and eliminates the need for additional fastening systems, ensuring effective sealing and wind resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If elastic brush seals are used in the slide, then the seal can maintain contact with the apron, but the bristles lose elasticity and wear out over time, reducing reliability
Solution Approach 1:
The patent replaces the durable but complex two-part joint with a simpler, more economical single-part seal element that is designed to be replaced periodically. This resolves the contradiction by accepting periodic replacement of a simpler component rather than maintaining a complex component indefinitely.
Solution Approach 2:
The patent changes the material parameters of the seal from elastic brush material to a non-elastic sealing material (such as rubber or plastic) that resists wear and maintains its sealing properties over time, fundamentally changing how the seal maintains contact with the apron.
2Reliability
If adhesive fastening means are used to fix the seal, then the seal can be attached to the profile, but the adhesive degrades under aging and stress, reducing reliability
Solution Approach 1:
The patent extracts and eliminates the adhesive fastening system entirely by integrating the seal directly into the profile structure through the groove and flange mechanism. This resolves the contradiction by removing the degrading adhesive component while maintaining secure seal attachment.
Solution Approach 2:
The patent merges the seal attachment function into the structural design of the profile itself, where the groove and flange provide both structural support and sealing retention without requiring separate fastening means.
3Reliability
If a two-part joint with internal and external parts is used, then the seal can function, but the design becomes complex and costly
Solution Approach 1:
The patent combines the internal part and external part of the joint into a single integrated seal element that performs both functions simultaneously. This resolves the contradiction by eliminating the complexity of assembling and coordinating two separate parts while maintaining the sealing functionality.
Solution Approach 2:
The single seal element is designed to perform multiple functions: providing the seal, maintaining contact with the apron, and being retained by the profile structure, thereby replacing what previously required multiple specialized components.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The simplified 'V' section slide seal design improves durability, reduces maintenance, and enhances wind resistance and airtightness by maintaining contact with the apron under various conditions, while eliminating the need for adhesive fastening systems.
Implementation Method 1
The elongated element is made of a deformable, flexible and/or elastic material
