Solution Overview

Problem

Existing closing mechanisms for sliding doors are complex and prone to damaging fragile materials, such as glass, during operation, and do not allow for easy simultaneous closure of multiple doors.

Innovation Solution

A mechanism featuring rotatable closing elements with a synchronization bar that ensures simultaneous locking or unlocking of multiple sliding doors, using a locking body and synchronization bar to coordinate the rotation of multiple closing elements, preventing or allowing translation of the doors.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If complex closing mechanisms are used to lock sliding doors, then the locking function is achieved, but the operation becomes difficult and fragile materials like glass may be damaged

Engineering Contradiction:
Improvelocking functionVSAvoidoperation simplicity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent combines multiple closing elements (first and second closing elements) into a single integrated closing mechanism that operates simultaneously. The synchronization bar links both closing elements together, allowing one operational movement to control both locking actions at once, thereby simplifying operation while maintaining reliable locking of multiple doors

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The synchronization bar acts as an intermediary mechanism that transmits the closing action from one closing element to the other. When one closing element is actuated, the synchronization bar transfers this movement to the second closing element, ensuring coordinated operation without requiring separate manual intervention for each door

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If individual closing mechanisms are used for each sliding door, then each door can be locked independently, but the mechanism complexity increases and simultaneous closure of multiple doors is not achieved

Engineering Contradiction:
Improveindependent door controlVSAvoidmechanism complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges multiple closing elements into a single synchronized system where the first and second closing elements are mechanically linked through the synchronization bar. This allows independent positioning capability for each door while achieving simultaneous closure through a single operational input, reducing overall mechanism complexity

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The synchronization bar serves multiple functions: it transmits closing movements between doors, maintains synchronized positioning, and enables both independent and simultaneous operation modes. This multi-functionality allows the system to adapt to different operational requirements without adding complexity

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A mechanism for closing sliding doors of furniture. The mechanism includes at least two rotatable closing elements, each associated with a respective door. A locking body is associated with the closing element for rotating and locking the closing element in either an open position or a closed position. The closing element also includes a locking portion that, through the rotation of the closing element, can pass from a first position in which the locking portion prevents the translation of the sliding doors of the furniture, to a second position which allows the translation of the sliding doors. The closing mechanism also includes a synchronization bar that makes the closing elements rotate as a unit, ensuring the simultaneous locking of the sliding doors in the closed or open position.
