Glass Door Lock with Chamfered Edge Profile
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing glass door locking devices are expensive to manufacture and lack adjustability, as they are typically fixed in place with a hole or a U-shaped pad that requires a greater distance between glass elements, limiting their positioning and maintenance.
Innovation Solution
A glass door lock with a chamfered design that allows the fitting to be freely positioned between the door and the floor or ceiling, using a locking pin and anchor plate system that can be adjusted or removed, eliminating the need for a fixed attachment to the door and reducing production costs by using a bevel instead of a bore.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a hole is made in the door glass to fix the lock, then the lock position is fixed, but the manufacturing cost increases and adjustability is lost
Solution Approach 1:
The invention extracts the lock from the door structure by removing the need for holes in the glass. The lock is instead attached to a profile that is clamped to the door edge, separating the locking function from the glass pane itself and eliminating the need for costly hole drilling through the glass.
Solution Approach 2:
The profile acts as an intermediary element between the lock and the door. Instead of fixing the lock directly to the glass, the profile is clamped to the door edge and provides a mounting surface for the lock, simplifying the attachment process and enabling easy adjustment.
2Ease of manufacture
If a U-shaped pad is glued or jammed to the glass, then the lock can be attached, but the distance between glass elements must be greater than norm allows
Solution Approach 1:
The invention moves the attachment point from the glass surface (2D) to the door edge profile (3D structure). By clamping the profile to the edge of the door rather than adhering to the glass surface, the system eliminates the need for increased spacing between glass elements while maintaining secure lock attachment.
3Stability of the object's composition
If the lock is fixed to the door, then the position is stable, but the lock cannot be removed or adjusted later
Solution Approach 1:
The clamp connection between the profile and the door edge is designed to be dynamically adjustable. The profile can be positioned at different locations along the door edge and repositioned or removed as needed, providing flexibility while maintaining stable lock attachment during use.
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
Enables cost-effective manufacturing and adjustability of the lock, maintaining safety distances and allowing for easy installation and removal, while providing a secure and adaptable locking mechanism.
Implementation Method 1
In the area of the bearing hole, a balancing spring is arranged, which is designed to compensate for uneven floors
Implementation Method 2
The locking pin is surrounded by a helical spring which is supported at one end on a radially projecting shoulder of the sleeve and on the other hand on a stop of the housing
