Flush Vehicle Window Lift Mating Structure for Sealing Precision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flush doors face challenges in guiding precision, dustproofing, strength enhancement, sealing performance, and assembly, particularly due to the lack of rigid support for the door glass, which affects the door's operation and aesthetics.
Innovation Solution
A mating structure comprising a glass guide groove, glass guide rail, door panel, and multiple sealing lips, where the glass guide groove is secured to the door and limits movement, and sealing lips provide dynamic sealing connections to prevent air and water ingress, enhancing assembly and sealing performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If frameless door structure is used to improve aesthetics, then overall appearance is improved, but sealing performance is compromised due to lack of rigid support for door glass
Solution Approach 1:
The door structure is segmented into multiple functional components: glass guide groove, glass guide rail, door glass, and door panel. This segmentation allows each component to perform its specific function - the guide groove and rail provide structural support and guidance, while the glass provides the flush aesthetic appearance, resolving the contradiction between aesthetics and sealing performance.
Solution Approach 2:
The glass guide groove and glass guide rail act as intermediary structures between the door glass and the door panel. These intermediaries provide the necessary rigid support and guidance for the glass, enabling both the aesthetic flush appearance and the reliable sealing performance through multiple sealing lips.
2Loss of energy
If glass is made flush with door panel to reduce wind resistance, then aerodynamic performance is improved, but traditional dustproof structures cannot be used making dustproofing difficult
Solution Approach 1:
The sealing lips are designed to be dynamic rather than static, allowing them to adapt to the flush configuration of the glass and door panel. This dynamic sealing approach maintains dustproofing capability while preserving the aerodynamic benefits of the flush design.
3Manufacturing precision
If glass guide groove has increased mating surfaces to improve guiding precision, then alignment between glass and door is improved, but assembly becomes difficult
Solution Approach 1:
The glass guide groove is segmented into distinct functional zones with mating surfaces at different locations. This segmentation allows for precise alignment through distributed contact points while maintaining ease of assembly by reducing the complexity of any single mating interface.
