Power Slide Window Stopper Adjustment for Flush Panel Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing power slide window systems suffer from a step formation between the slide panel and the window glass pane due to assembly inaccuracies, affecting the appearance and commercial value.
Innovation Solution
A power slide window design featuring a guide rail with a pin guide groove and a slider with a pin drive groove, where the pin drive groove is inclined and a stopper with a position adjustment structure to align the slide panel with the window glass pane, reducing the step regardless of assembly accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the pin drive groove extends in parallel with the groove main portion to retain the slide panel in the closed position, then the slide panel can be retained in the closed position even if the slider is not stopped at an exact position, but assembly inaccuracies cause a step between the slide panel and the window glass pane
Solution Approach 1:
The stopper is made adjustable in position along the slider guide groove, transforming a static structure into a dynamic one that can adapt to assembly variations. The stopper can be repositioned to compensate for misalignment between the pin drive groove and groove main portion, ensuring the slide panel aligns properly with the window glass pane while maintaining retention functionality.
Solution Approach 2:
The position of the stopper along the slider guide groove is changed as a variable parameter to compensate for assembly inaccuracies. By adjusting the stopper's position, the system can accommodate variations in the relative positioning of the pin drive groove and groove main portion, eliminating the step between the slide panel and window glass pane while preserving the retention effect.
2Device complexity
If the stopper position is fixed in the slider guide groove, then the structure is simple, but the slide panel cannot be properly aligned with the window glass pane when assembly accuracy is poor
Solution Approach 1:
The stopper positioning system is transformed from a fixed static structure to an adjustable dynamic structure. The stopper can be repositioned along the slider guide groove to compensate for assembly inaccuracies, allowing proper alignment of the slide panel with the window glass pane while adding minimal complexity through the use of engagement protrusions and recesses.
Solution Approach 2:
The adjustable stopper position allows for preliminary adjustment during assembly to compensate for anticipated misalignments. The engagement protrusions and recesses enable the stopper to be positioned at different locations along the slider guide groove before final assembly, ensuring proper alignment is achieved even when component tolerances vary.

AI summary
To provide a power slide window in which, irrespective of the assembly accuracy, the step between the slide panel and the window glass pane in the closed state can be reduced, at least one pin drive groove (30) formed in a slider (20) to engage at least one pin (16) extends in a direction crossing a panel surface (2b) of the window glass pane (2) and inclined to the direction of extension of a groove main portion (26a) of a pin guide groove (26). A stopper (23) configured to limit the movement of the slider (20) toward the closed position is provided in a slider guide groove (27), and a position adjustment structure (32) capable of adjusting the position of the stopper (23) in the direction of extension of the slider guide groove (27) is provided. By adjusting the position of the stopper (23) by the position adjustment structure (32), it is possible to limit the movement of the slider (20) toward the closed position at a position where the slide panel (3) aligns with the window glass pane (2).
