Wedging Door Rail Assembly for Variable Glass Panel Thickness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door rail systems face challenges in efficiently accommodating varying doorway widths, panel thicknesses, and angular adjustments, while also requiring complex and permanent attachment methods that hinder easy replacement or repair.
Innovation Solution
A door rail system featuring a core rail with a clamping channel, clamping rails, and pulling rails, allowing for adjustable panel thicknesses and angular adjustments, with modular side covers and concealed hardware, and a mechanism for easy attachment and detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If structural adhesives are used to attach rails to glass panels, then the attachment is strong and secure, but the rail cannot be removed for replacement or repair
Solution Approach 1:
The attachment system is divided into separate components: a rail body and a removable cover assembly that can be detached and reattached. This segmentation allows the rail to be removed and replaced without damaging the glass panel, while still providing strong attachment when assembled. The cover assembly acts as an intermediary that maintains the strong bond while enabling replacement.
2Stability of the object's composition
If a fixed rail system is used, then the structure is simple and stable, but it cannot accommodate varying doorway widths or panel thicknesses
Solution Approach 1:
The rail system incorporates adjustable elements including a movable cover assembly that can be repositioned along the rail body, and adjustable clamping mechanisms that can accommodate different panel thicknesses. This dynamic adjustability allows the same rail structure to adapt to varying doorway widths and panel dimensions while maintaining structural stability when installed.
3Adaptability or versatility
If multiple components are used to accommodate varying dimensions, then adaptability is improved, but device complexity increases
Solution Approach 1:
The rail body is designed as a universal component that can work with various cover assemblies and adjustment mechanisms. The cover assembly serves multiple functions: it provides the attachment interface to the glass panel, enables adjustment of the rail position, and allows for easy removal and replacement. This multi-functionality reduces the need for entirely different components for different applications.
4Ease of manufacture
If modular side covers are used, then ease of installation and aesthetic flexibility are improved, but the attachment mechanism becomes more complex
Solution Approach 1:
The cover assembly is pre-assembled with the attachment mechanisms and adjustment components before installation. This preliminary assembly simplifies the installation process, as the entire adjustable assembly can be installed as a single unit and then adjusted in place. The complex mechanisms are pre-configured, reducing the complexity of the installation process even though the attachment mechanism itself is sophisticated.

AI summary
An improved door rail system for holding a panel, such as a glass panel, is presented. The door rail system includes a core rail and clamping rails having a wedging geometry so that when the clamping rails are actuated with respect to the core rail, clamping force is applied to the glass panel to secure the panel within the core rail. The improved door rail system accommodates panels of varying thickness, features the use of modular side covers and incorporates a door to door jamb adjustment device allowing for angular adjustments.
