Sliding Door Locking Device Integrated with Limiting Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing support systems for sliding doors, particularly sliding glass doors, face challenges in maintaining a compact installation space while ensuring stable door guidance and aesthetically integrating a lock mechanism, as conventional solutions require additional space for the lock and limiting device, making them unsuitable for ceiling recesses or adjacent walls.
Innovation Solution
A support system with a compact locking device that forms a structural unit with the limiting device, utilizing a locking bar with automatic restoring force and an electromagnet-driven bolt, allowing for a small installation space and ensuring the bolt automatically unlocks in case of power failure, enabling stable door guidance close to the lateral edge with minimal protrusion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional lock device is arranged on the side edge of the door leaf, then the door can be locked securely, but the installation space in the longitudinal direction of the running rail increases and the lock is visible through the glass door
Solution Approach 1:
The locking device is merged with the limiting device to form an integrated structural unit. The lock housing and limiting device housing are combined into a single compact structure that is mounted on the running rail, eliminating the need for separate side-edge lock installation and reducing the longitudinal space requirement.
Solution Approach 2:
The lock device is repositioned from the side edge of the door leaf to the running rail in the longitudinal direction. By mounting the integrated locking and limiting device structure on the running rail, the space utilization shifts to a different dimensional arrangement that reduces protrusion beyond the door leaf.
2Stability of the object's composition
If the running gear is arranged close to the lateral edge of the door leaf for stable guidance, then door guidance stability improves, but the installation space required for the locking device and limiting device increases
Solution Approach 1:
The locking device and limiting device are merged into a single integrated structural unit with shared housing and mounting structure. This consolidation reduces the total longitudinal space required while maintaining the functional requirements for both door guidance stability and secure locking.
Solution Approach 2:
The integrated structural unit serves multiple functions simultaneously: the limiting device provides door guidance stability, the locking device provides secure locking, and the shared housing and mounting structure reduce overall space requirements. This multi-functional design allows the running gear to be positioned optimally for stability without compromising locking functionality.
3Reliability
If a bolt is actuated against automatic restoring force into a locking position, then secure locking is achieved, but the space required for the drive device increases
Solution Approach 1:
The bolt is equipped with an automatic restoring force mechanism that automatically returns the bolt to the unlocking position when the drive force is removed. This self-restoring feature eliminates the need for complex reverse actuation mechanisms, reducing the space required for the drive device while maintaining secure locking capability when actuated.
Solution Approach 2:
The locking mechanism utilizes a bolt with automatic restoring force that changes its position based on the presence or absence of actuation force. The bolt can be actuated against the restoring force into a locking position for secure locking, and automatically returns to the unlocking position when the force is removed, providing a space-efficient drive device design.
4Ease of operation
If the running rail protrudes laterally beyond the door leaf when closed, then the locking device has sufficient space for operation, but the aesthetic appearance deteriorates and ceiling recess installation becomes difficult
Solution Approach 1:
The locking device and limiting device are merged into a single integrated structural unit that is mounted on the running rail. This integration allows the entire assembly to be positioned within the longitudinal space of the running rail without requiring lateral protrusion beyond the door leaf, maintaining aesthetic appearance and enabling ceiling recess installation.
Solution Approach 2:
The locking device is repositioned from lateral protrusion beyond the door leaf to mounting on the running rail in the longitudinal direction. This dimensional repositioning provides sufficient operation space for the locking mechanism while maintaining a clean aesthetic appearance and compatibility with ceiling recess installations.
