Seal Assembly With Lateral Support Webs For Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sealing arrangements with pivotally connected U-shaped cap and end plug parts suffer from stability issues and inadequate sealing effectiveness.
Innovation Solution
A sealing arrangement featuring a base body with lateral support webs and an end plate, where the support webs are stiffened for improved contact pressure and sealing, and an attachment part with an inner contour matching the profile seal for secure fit without additional holding elements, utilizing a three-dimensional injection molded hard plastic design with channels for sealing compound and an extension for increased contact pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a pivotally connected U-shaped cap and end plug design is used, then the sealing arrangement can be assembled, but stability is compromised
Solution Approach 1:
The patent removes the problematic pivotal connection element from the design. Instead of using a film hinge to connect the cap and end plug, the invention integrates these components into a single-piece construction, eliminating the source of instability while preserving assembly capability through alternative means
Solution Approach 2:
The patent merges the cap and end plug into a single integrated sealing piece. This consolidation eliminates the pivotal connection between separate parts, thereby improving stability while maintaining the functional separation of components through integral design features
2Stability of the object's composition
If additional holding elements are used to secure the sealing piece, then stability improves, but device complexity increases
Solution Approach 1:
The sealing piece is designed to secure itself to the profile seal through its own geometric features. The attachment part's inner contour is shaped to match the profile seal's outer contour, creating a self-holding mechanism that eliminates the need for additional holding elements like clips or fasteners
Solution Approach 2:
The patent applies specific geometric contouring to the attachment part of the sealing piece. The inner contour is locally adapted to match the outer contour of the profile seal, creating a form-fit connection that provides stability without adding overall device complexity
3Ease of manufacture
If the support webs are not stiffened, then manufacturing is simpler, but contact pressure transfer to the seal is insufficient
Solution Approach 1:
The patent adds a longitudinal dimension to the support webs by incorporating angled side parts. This dimensional enhancement stiffens the webs in the longitudinal direction, improving their load-bearing capacity and contact pressure transfer capability without fundamentally changing the manufacturing process
4Ease of manufacture
If the joint to the mullion seal is not backed with sealing material, then application is simpler, but sealing effectiveness is insufficient
Solution Approach 1:
The angled side parts of the support webs are designed to pre-position and prepare the joint area for sealing material application. By creating a geometrically prepared surface with proper angulation, the design facilitates subsequent sealing material application and ensures optimal sealing effectiveness
