Center Seal Spring Elements for Window Frame Tightness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing center seals do not provide optimal tightness when attached to frame profiles, as they are not securely fixed, leading to suboptimal sealing performance compared to other designs like EP 20 2010 008 921.
Innovation Solution
A central seal profile with sealing spring elements placed in a compressed state when latched to the frame profile, ensuring a defined and secure seat, utilizing a combination of plastics where the base body is made of a less elastic material and the sealing elements are elastomeric, with hook sections and spring elements strategically positioned for enhanced sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the center seal is attached to the frame profile using a simplified fastening method (locking hooks), then the ease of operation is improved, but the reliability of the sealing connection deteriorates
Solution Approach 1:
The patent applies parameter changes by introducing elastic sealing spring elements that generate compressive force. When the center seal is attached to the frame profile, the sealing spring elements are compressed between the center seal and the frame profile, creating a predefined compressive force that ensures tight sealing connection while maintaining the simplified locking hook fastening method.
2Reliability
If sealing spring elements are added to improve sealing tightness, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The patent merges the sealing function and the fastening function into a single integrated assembly. The sealing spring elements are positioned to act simultaneously on both the center seal and the frame profile during the attachment process, so that one attachment action achieves both secure fastening and effective sealing, rather than requiring separate mechanisms for each function.
3Ease of operation
If the center seal is made lighter and easier to attach, then the ease of operation is improved, but the strength of the connection deteriorates
Solution Approach 1:
The sealing spring elements provide self-service by automatically generating the necessary compressive force to ensure tight sealing and strong connection. Once the center seal is attached to the frame profile using the simplified locking hooks, the sealing spring elements self-compress between these two components, creating the predefined compressive force needed for reliable sealing without requiring additional fastening elements or complex assembly steps.
