Vehicle Window Assembly With Releasable Transport Protection Strip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle window assemblies face challenges during transport and storage, particularly due to partial detachment of the profile strip from the window, and the complexity of removing and reusing keder strips for protection.
Innovation Solution
A vehicle window assembly that includes a transport protection strip with an insertion portion for the receiving groove of the profile strip and a contact portion that overlaps the window's main face, both of which are releasably connected using a connector, providing additional stabilization and protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a transport protection strip (keder strip) is inserted in the receiving groove to prevent deformation, then the receiving groove is protected from deformation, but the profile strip may partially detach from the window due to insufficient securing of the protection strip
Solution Approach 1:
The patent combines two functions into a single transport protection strip: (1) protecting the receiving groove from deformation by insertion, and (2) securing the profile strip to the window through additional connection elements. The protection strip integrates both the groove-protection function and the profile-strip-securing function, eliminating the need for separate measures and ensuring both objectives are achieved simultaneously.
Solution Approach 2:
The transport protection strip acts as an intermediary element between the profile strip and the window. It not only protects the receiving groove but also provides additional connection points that mediate the connection between the profile strip and the window, preventing detachment during transport while maintaining the integrity of the receiving groove.
2Reliability
If keder strips are configured to match a specific profile strip geometry to ensure secure holding, then the protection strip is held securely, but the device complexity increases and requires elaborate manufacturing and disposal arrangements
Solution Approach 1:
The transport protection strip is designed with universal applicability through standardized connection elements that can be used with different profile strip geometries. The connection elements are configured to provide secure holding without requiring custom matching to specific profile strip designs, reducing device complexity while maintaining reliability across different applications.
Solution Approach 2:
The patent employs connection elements with adjustable or adaptable parameters (such as flexible mounting options or standardized interfaces) that allow the protection strip to be securely held without requiring elaborate custom manufacturing for each specific profile strip geometry. This reduces complexity while maintaining secure holding through parameter optimization rather than geometric matching.
3Productivity
If the window is stored in an upright posture with edge support, then storage space is optimized, but the weight of the window acts on the profile strip causing receiving groove deformation
Solution Approach 1:
The transport protection strip is installed in advance before upright storage, providing preliminary protection to the receiving groove. The connection elements are pre-positioned to counteract the weight-induced forces that will act on the profile strip during upright storage, preventing deformation before it occurs and maintaining receiving groove integrity while allowing efficient upright storage.

AI summary
A vehicle window assembly includes a vehicle window, a profile strip and a transport protection strip. The vehicle window includes a first main face, a second main face facing away from the first main face, and an edge connecting the first to the second main face. The profile strip is arranged at a peripheral region of the vehicle window by a first connecting region, and has a second connecting region comprising a receiving groove configured to connect to a component adjacent to the vehicle window. The transport protection strip includes an insertion portion which is received in, and releasably connected to, the receiving groove. The transport protection strip includes a contact portion which at least partially overlaps the first main face of the vehicle window in the peripheral region and is releasably connected to the vehicle window by a connector acting between the contact portion and the first main face.
