Sliding Door Locking Device with Groove Guide for Slim Corner Arrangements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sliding door locking systems are often heavy and unsuitable for corner arrangements in modern architecture, where a slim and light design is required, and they struggle to accommodate two movable door leaves moving in opposite directions without a support element at the corner.
Innovation Solution
A locking device with a sliding body and a lifting body coupled via a groove guide, where the sliding body's movement is converted into a lifting movement, allowing for a slim and light design that can lock the door leaves in a closed position without a support element at the corner, using a linear drive and sensor elements for precise positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional two-piece latch is used in the door frame, then reliable locking is achieved, but the device becomes heavy and unsuitable for corner arrangements
Solution Approach 1:
The locking device is divided into functionally independent components: a lifting body for actuation, a sliding body for movement conversion, and a groove guide for motion transformation. This segmentation allows each component to be optimized for its specific function while reducing overall weight and complexity.
Solution Approach 2:
The locking mechanism uses dynamic movement conversion where horizontal movement of the sliding body is transformed into vertical lifting movement of the actuating element through the groove guide. This dynamic approach replaces heavy static locking components with lighter dynamic elements that achieve the same locking function.
2Reliability
If a conventional locking device is used, then secure locking is achieved, but the design becomes bulky and unsuitable for modern slim corner arrangements
Solution Approach 1:
The groove guide converts movement from one dimension (horizontal sliding) to another dimension (vertical lifting). This dimensional transformation allows the actuating element to engage the locking device from above in a slim profile, eliminating the need for bulky lateral locking mechanisms.
Solution Approach 2:
The mechanism uses dynamic movement conversion where horizontal movement of the sliding body is transformed into vertical lifting movement of the actuating element through the groove guide. This dynamic approach replaces heavy static locking components with lighter dynamic elements that achieve the same locking function.
3Stability of the object's composition
If support elements are installed at corners for sliding doors, then structural stability is improved, but the modern architectural requirement for corner windows/doors without support elements is compromised
Solution Approach 1:
The locking device integrated in the door frame serves multiple functions: it provides structural support for the locking mechanism, enables secure locking of door leaves, and maintains the architectural requirement for clean corner arrangements without additional support elements. This multi-functionality resolves the contradiction between stability and adaptability.
4Ease of manufacture
If a simple linear drive is used, then ease of manufacture is improved, but precise positioning control may be insufficient
Solution Approach 1:
The groove guide acts as an intermediary mechanical element that transforms simple linear horizontal movement into precise vertical lifting movement. This passive mechanical guidance system provides positioning accuracy without requiring complex control mechanisms, maintaining ease of manufacture while achieving precise positioning.
