Sliding Window Sealing Profile With Closure Lip for Flush Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional sealing arrangements for sliding windows, particularly in vehicles, suffer from an unattractive vertical step between the window and the frame, which affects aerodynamics and security, as they fail to effectively prevent transversal movements of the window that could compromise the passenger compartment's integrity.
Innovation Solution
A sealing profile strand with a support segment made of a hard material and a sealing segment made of a soft material, featuring a vertical protrusion and window edge closure lip, is designed to be mounted on the frame profile. This configuration minimizes the vertical step, enhances sealing performance, and impedes transversal movements by engaging the window edge, thereby improving safety and aerodynamics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional U-shaped sealing profile strands are used to guide and seal the sliding window, then sealing performance is improved, but a large vertical step is created between the window and frame, affecting aerodynamics and appearance
Solution Approach 1:
The sealing profile strand is divided into distinct functional segments: a support segment for structural mounting and a sealing segment for sealing and guiding functions. This segmentation allows each part to be optimized independently, with the sealing segment providing effective sealing while the support segment managing the structural connection, thereby reducing the overall vertical step.
Solution Approach 2:
The invention repositions the guide structures from external U-shaped profiles to internal arrangements within the window assembly. By moving the guiding function to the inside of the window and using the sealing segment to bridge the gap, the external vertical step is minimized while sealing performance is maintained through the sealing segment's engagement with both the window and frame.
2Shape
If guide structures are arranged on the inside of the window only, then the outer appearance becomes flush, but security against transversal movements is compromised
Solution Approach 1:
The sealing segment is designed to perform multiple functions simultaneously: it provides sealing against the frame, guides the window movement, and acts as a security feature by engaging the window edge to prevent transversal movements. This multi-functionality allows the flush outer appearance to be maintained while security requirements are met through the same component.
Solution Approach 2:
The sealing segment acts as an intermediary element between the window and frame that not only seals and guides but also provides mechanical engagement to prevent unauthorized transversal movements. The vertical protrusion and window edge closure lip create a mechanical interlock that serves as a security barrier while maintaining the aesthetic flush appearance from the outside.
3Object-generated harmful factors
If the vertical step is reduced for aerodynamic perfection, then aerodynamic performance is improved, but the ability to prevent transversal window movements is reduced
Solution Approach 1:
The sealing segment incorporates specific local features such as the vertical protrusion and window edge closure lip that are strategically positioned to prevent transversal movements. These localized structural elements provide the necessary mechanical engagement and security function while the overall compact design maintains the flush appearance and reduces aerodynamic turbulence.
