Curved Window Glass Holder Structure for Smooth Arcuate Sliding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional holder-equipped window glasses experience friction resistance issues during sliding movement along circular arcuate paths, preventing smooth operation.
Innovation Solution
The window glass is designed with a curved shape and holders featuring a connecting portion with a circular arcuate portion, allowing for smooth sliding by matching the curvature of the sliding path, reducing friction resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional holders with straight connecting portions are used, then the structure is simple, but friction resistance increases and smooth sliding movement cannot be achieved
Solution Approach 1:
The connecting portion of the holder is designed with a circular arcuate shape that matches the curvature radius of the sliding path. This curvature allows the holder to follow the arcuate trajectory during window glass movement, significantly reducing friction resistance and enabling smooth sliding operation along the circular arcuate path.
2Ease of operation
If the window glass is formed in a curved shape, then it can follow the circular arcuate sliding path, but manufacturing complexity increases
Solution Approach 1:
The window glass is formed with a curved shape having a first radius of curvature that corresponds to the second radius of curvature of the holder's connecting portion. This matched curvature enables the glass to naturally follow the circular arcuate sliding path defined by the holder, facilitating smooth movement while maintaining manufacturing feasibility through standardized curvature ratios.

AI summary
A holder-equipped window glass includes a window glass having a holder and formed in a curved shape having a first radius of curvature in section in a sliding movement direction in a state where the window glass is mounted on a vehicle. The holder includes a connecting portion and a holder body. The connecting portion extends in a direction away from a lower edge of the holder body, and the connecting portion at least partly includes a circular arcuate portion having a second radius of curvature in section in the sliding movement direction.
