Electromechanical Sliding Door Locking System with Segmented Bolt
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sliding door furniture locking systems require additional components and structural modifications, making them difficult to install and retrofit, as they need to prevent doors from being lifted out and ensure functional interaction of handles.
Innovation Solution
An electromechanical locking system with a bolt, receptacle, and electric motor integrated into the sliding doors, allowing for easy mounting and retrofitting without structural changes, featuring a guide element for torsion-proof movement and remote control capabilities via an active transponder.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking system is mounted underneath the running shoe profiles as in prior art, then the locking function is achieved, but the installation becomes complex and retrofitting becomes difficult or impossible
Solution Approach 1:
The locking system is divided into separate components: a locking element with bolt that can be mounted on one sliding door, and a separate bolt receptacle on the other sliding door. This segmentation allows independent mounting without requiring modifications to the furniture body or running shoe profiles, enabling easy retrofitting while maintaining reliable locking function.
Solution Approach 2:
The locking system is extracted from the furniture body structure and relocated to be mounted directly on the sliding doors themselves. This extraction eliminates the need for recesses in the furniture body and mounting under running shoe profiles, simplifying installation and enabling retrofitting of existing furniture.
2Reliability
If different components are equipped on sliding doors to implement anti-jemmy device, then the locking function is achieved, but the device complexity increases
Solution Approach 1:
The locking element and bolt mechanism are merged into a single integrated component that can be mounted on one sliding door. The bolt itself serves as both the locking protrusion and the anti-jemmy element, eliminating the need for separate handle pieces with tongue and groove connections, thereby reducing device complexity while maintaining anti-jemmy functionality.
Solution Approach 2:
The bolt serves multiple functions simultaneously: it provides the locking action by engaging with the bolt receptacle, prevents door displacement, and acts as an anti-jemmy element. This multi-functionality reduces the number of components needed while achieving comprehensive security.
3Ease of manufacture
If recesses are made in the furniture body to accommodate the locking system, then the locking system can be installed, but retrofitting becomes difficult or impossible
Solution Approach 1:
The locking system is extracted from the furniture body and relocated to mount directly on the sliding doors. This eliminates the need for recesses in the furniture body, allowing the locking system to be installed on existing furniture without structural modifications, thereby enabling retrofitting while maintaining full installation capability.
Solution Approach 2:
The locking system is segmented into door-mounted components rather than being integrated into the furniture body. This segmentation allows the locking system to be independently installed on sliding doors without requiring modifications to the furniture structure, enabling both new installations and retrofits.
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 easy installation and retrofitting of the locking system on existing sliding door furniture, ensuring secure closure and preventing door displacement or lifting, with remote control functionality and position detection for safe operation.
Implementation Method 1
an electric motor engaging in the bolt
Implementation Method 2
a guide element being formed on the housing that can be inserted into a Housing facing standing recess of the bolt for guiding the bolt in the closing direction
Implementation Method 3
The control unit for controlling the electric motor has an active transponder, in particular an RFID, RD or Bluetooth transponder
