Dual-Blade Tool for Motor Vehicle Window Glass Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The insertion of a window into the upper seal of a motor vehicle door often faces difficulties due to deformation of the seal, leading to incomplete closure and the need for costly retouching.
Innovation Solution
A tool with two blades made of rigid and elastic material, featuring a first zone where they are in contact and a second zone where they are spaced apart and parallel, guides the window into the seal by engaging on the outer wing of the seal, allowing for complete closure without obstacles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the window is forced into the deformed seal, then the window can be inserted, but the seal deforms further and blocks the window before complete closure
Solution Approach 1:
The tool acts as an intermediary device between the window and the deformed seal. It includes a first element that engages the outer face of the seal's outer wing and a second element that engages the inner face, creating a controlled insertion path that prevents further seal deformation and ensures complete window closure.
2Productivity
If the seal is left untreated, then the door assembly is simple, but the window cannot be completely closed due to seal deformation
Solution Approach 1:
The tool performs preliminary action by pre-positioning the seal in the correct orientation and engagement state before the window is inserted. The first and second elements engage the seal's outer and inner faces respectively, preparing the seal to guide the window to its final closed position without obstruction.
3Reliability
If costly retouching is performed on the seal, then the window can be closed completely, but the manufacturing cost increases significantly
Solution Approach 1:
The tool enables self-service by allowing the installer to correct seal engagement issues and achieve complete window closure using the tool itself, without requiring external retouching operations. The first and second elements work together to guide the window through the seal, enabling the installer to self-correct positioning issues.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The tool ensures the window can be fully closed without deformation-related issues, eliminating the need for costly alterations and ensuring proper sealing.

AI summary
Tool (1) to assist with inserting a window glass (2) in the upper sealing strip (3) of a motor vehicle door (4), characterized in that it comprises two blades (5, 6) made of a rigid and elastic material comprising a first zone (5a, 6a) in which the two blades (5, 6) are in contact with one another over part of their length, and a second zone (5b, 6b) in which the two blades (5, 6) are spaced apart and parallel over the remainder of their length, the ends of the two blades in this second zone (5b, 6b) being intended to fit over the outer flange (3a) of said sealing strip (3) to press respectively against the exterior face and against the interior face of said outer flange (3a) of the sealing strip (3).
