Power Slide Window Guide Rail Groove Merging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing power slide window designs have a large projecting dimension of the guide rail from the panel surface due to the side-by-side formation of the slider guide groove and pin guide groove, which increases the overall size and complexity of the mechanism.
Innovation Solution
The design incorporates a guide rail with a pin guide groove that extends along the panel surface, featuring a groove main portion and an extension portion, where the pin drive groove is formed to receive the pin, allowing the pin to move in a direction crossing the panel surface, and the slider guide groove and pin guide groove are formed with overlapping widths to reduce the projecting dimension by sharing common portions, enabling efficient sliding and reduced size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the slider guide groove and pin guide groove are formed side by side in the direction crossing the panel surface, then the guidance function is ensured, but the projecting dimension of the guide rail from the panel surface becomes large
Solution Approach 1:
The slider guide groove and pin guide groove are merged into a single integrated groove structure in the guide rail. The groove has a first portion for guiding the pin in the opening/closing direction and a second portion extending in the crossing direction for guiding the slider. This merging eliminates the need for separate side-by-side grooves, thereby reducing the projecting dimension while maintaining both guidance functions.
Solution Approach 2:
The groove structure transitions from a two-dimensional side-by-side arrangement to a three-dimensional integrated form. The groove extends in multiple directions (both along the panel surface and crossing it), creating a spatial configuration that achieves dual guidance functionality without increasing the projecting dimension in any single direction.
2Reliability
If the guide rail is designed with separate slider guide groove and pin guide groove, then the guidance paths are clearly defined, but the overall size and complexity of the mechanism increases
Solution Approach 1:
Two separate guidance grooves are merged into one integrated groove structure that serves both functions. The groove contains distinct portions for pin guidance and slider guidance, clearly defining both guidance paths while reducing the number of separate components and simplifying the overall mechanism.
Solution Approach 2:
The single guide rail groove structure performs multiple functions: it guides the pin in the opening/closing direction through its first portion, guides the slider in the crossing direction through its second portion, and provides structural support. This multi-functionality reduces mechanism complexity while maintaining clear guidance path definition.

AI summary
To provide a power slide window in which the projecting dimension of the guide rail from the panel surface is small, the guide rail (4) defines a pin guide groove (26) that includes a groove main portion (26a) extending along a panel surface (2b) and at least one groove extension portion (26b) configured to drive a slide panel (3) in a direction to approach the window glass pane (2) via a pin (16) when the slide panel reaches the vicinity of the closed position. A slider guide groove (27) provided in the guide rail 4 to allow sliding of the slider 20 which is slidingly driven in the opening and closing direction and a groove main portion (26a) of a pin guide groove (26) are formed at least partially in common with each other.
