Sunroof Waterproof Strip Assembly Using an Integrated End Plug
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing assembly process for vehicle sunroof waterproof strips is complicated due to the need for a positioning assembly and hot welding, making it difficult to install the rubber strip onto the glass panel.
Innovation Solution
A sunroof device design featuring a window frame with an outwardly extended end seat and end plug, allowing the waterproof strip to be easily assembled by engaging it into a receiving space formed by the end plug and channel trough, eliminating the need for a separate positioning assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a positioning assembly and hot welding process are used to install the rubber strip, then the waterproof strip can be securely positioned, but the assembly process becomes complicated and time-consuming
Solution Approach 1:
The patent extracts and eliminates the positioning assembly from the system by integrating its positioning function directly into the window frame structure. The end seat with positioning groove and limiting ridge provide inherent positioning capability, removing the need for separate positioning components and simplifying the assembly process while maintaining reliable waterproof strip positioning.
Solution Approach 2:
The patent merges the positioning function with the window frame structure by forming the end seat and positioning groove as integral parts of the window frame. This combination eliminates the need for separate positioning assemblies and reduces the number of components, making the assembly process simpler while ensuring reliable waterproof strip positioning.
2Manufacturing precision
If a positioning assembly is used to position the rubber strip, then the waterproof strip can be accurately positioned, but additional components and assembly steps are required
Solution Approach 1:
The patent combines the positioning function with the window frame structure itself. The end seat and positioning groove are formed as integral parts of the window frame, eliminating the need for separate positioning assemblies. This reduces the number of components while maintaining accurate positioning of the waterproof strip through the built-in structural features.
3Strength
If hot welding is used to connect the window frame to the positioning assembly, then a strong connection is achieved, but the assembly process becomes more complex
Solution Approach 1:
The patent removes the positioning assembly and hot welding process from the system by integrating the positioning function directly into the window frame. The end seat with positioning groove and limiting ridge provide inherent positioning and retention capability, eliminating the need for separate positioning components and complex welding operations, thereby simplifying the assembly process while maintaining connection strength.

AI summary
A sunroof device includes a glass panel, a window frame and a waterproof strip. The window frame is disposed on a periphery of the glass panel. A periphery of the window frame is outward extended with an end seat. The end seat is disposed with an end plug. The end plug projects from the end seat. A projecting direction of the end plug is parallel with an outer edge of the window frame. The waterproof strip is attached on the outer edge of the window frame and is in a hollow manner to form a receiving space therein. The receiving space is in a tubular manner. The end plug is extended along a longitudinal direction of the waterproof strip to be embedded in the receiving space of the waterproof strip.
