Furniture Sliding Door Locking Bolt with Integrated Blocking Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sliding door furniture locking systems prevent doors from being lifted out but fail to secure them from being pushed away from walls or other sliding doors, necessitating additional components for functional interaction.
Innovation Solution
An electromechanical locking system with a movable locking bolt and a blocking element that can be displaced between a locking and neutral position, using an electric motor to secure the sliding door in place by protruding into a bolt receptacle and blocking displacement, with a drive bolt and spring element for efficient locking and unlocking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking bolt protrudes into a pocket of the sliding door to prevent the door from being pushed away, then the sliding door is secured against lateral movement, but the device complexity increases due to additional components needed for proper interaction
Solution Approach 1:
The locking element is integrated into the locking bolt as a single component rather than separate parts. The locking element is received in a cavity of the locking bolt and moves relative to it, combining multiple functions (locking and anti-prying) into one unified structure, thereby reducing device complexity while maintaining security
Solution Approach 2:
The locking bolt serves multiple functions: it prevents the sliding door from being pushed away by protruding into the pocket, and it prevents prying open by housing the locking element that engages with the handle. This multi-functionality eliminates the need for separate components, reducing overall system complexity
2Reliability
If a locking element is added to prevent the sliding door from being pulled out, then the lifting protection is improved, but the device complexity increases due to additional components
Solution Approach 1:
The locking element is integrated into the locking bolt structure, received in a cavity and moving relative to it. This integration combines the anti-lifting function with the existing locking bolt, avoiding the need for separate anti-lifting components and reducing overall device complexity
Solution Approach 2:
The locking element is nested within the locking bolt, received in its cavity. This nested arrangement allows the locking element to be housed within the existing locking bolt structure, eliminating the need for additional external components and simplifying the overall device
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
Effectively prevents sliding doors from being pushed away or pulled out by securing the door in place with the electromechanical locking system, enhancing security and functionality without the need for additional components.
Implementation Method 1
an electric motor (9) which can move the locking bolt (7) between a release position and a locking position
Implementation Method 2
a spring element (6), in particular a compression spring, which can return the locking bolt (7) into the release position

AI summary
An electromechanical locking system for a piece of furniture with at least one sliding door (2) movable on a track, has a locking bolt (7) which can be moved between a release position and a locking position by means of an electric motor (9) in and against a closing direction (x), wherein a locking element (10) is received in a cavity of the locking bolt (7), wherein the locking element (10) is displaceable between a locking position projecting from an opening (16) in a lateral surface (23) of the locking bolt (7) and a neutral position not projecting from this.
