Solution Overview

Problem

Sliding door closer sets face challenges when the trigger mounting position is incorrectly set, as it cannot be adjusted without demolishing the door pocket, leading to installation errors and maintenance difficulties.

Innovation Solution

A sliding door closer set design featuring a trigger integrated plate that can be adjusted from outside the door pocket, with a rail system comprising an outer and inner rail, allowing the trigger position to be corrected without dismantling the pocket, and enabling easy maintenance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the trigger is arranged inside the door pocket, then the sliding door can be pulled into the door pocket, but the trigger position cannot be corrected without demolishing the door pocket

Engineering Contradiction:

Improvesliding door pulling functionVSAvoidtrigger position adjustment

Core Design Contradiction:

ReliabilityVSEase of repair

Solution Approach 1:

The trigger assembly is segmented into two parts: the trigger itself located inside the door pocket and the trigger integrated plate mounted on the rail outside the door pocket. This segmentation allows the trigger integrated plate to be adjusted independently on the rail without demolishing the door pocket structure, while the trigger inside the door pocket remains fixed to perform its pulling function reliably.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The trigger integrated plate serves as an intermediary component that connects the trigger inside the door pocket to the rail outside the door pocket. It transmits the engagement force from the closer to the trigger while allowing positional adjustment on the rail, thus mediating between the fixed trigger function and the adjustable positioning requirement.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of manufacture

If the trigger is not arranged inside the door pocket, then construction errors can be avoided, but the sliding door cannot be pulled into the door pocket

Engineering Contradiction:

Improveconstruction error preventionVSAvoidsliding door pulling function

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

By segmenting the trigger assembly into the trigger inside the door pocket and the trigger integrated plate outside, the system maintains the pulling function reliability while allowing the external plate to be positioned accurately on the rail during construction, avoiding mounting errors.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The trigger integrated plate acts as an intermediary that enables accurate positioning and mounting on the rail outside the door pocket, preventing construction errors, while still transmitting force to the trigger inside the door pocket to maintain the pulling function.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Reliability

If the trigger is arranged inside the door pocket, then the sliding door can be pulled into the door pocket, but the trigger position cannot be adjusted from outside the door pocket

Engineering Contradiction:

Improvesliding door pulling functionVSAvoidtrigger position adjustment

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The trigger assembly is divided into the fixed trigger inside the door pocket that performs the pulling function and the adjustable trigger integrated plate outside that can be repositioned on the rail, allowing position adjustment without compromising the pulling function.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The trigger integrated plate serves as an intermediary component that can be adjusted on the rail from outside the door pocket, enabling position changes while the trigger inside the door pocket remains fixed to maintain reliable pulling function.

Inventive Principle:

Principle #24Intermediary (Mediator)

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 adjustment of the trigger position from outside the door pocket, preventing trigger misalignment, simplifying centering operations, and facilitating maintenance without damaging the door pocket structure.

Implementation Method 1

The dynamic force to pull the sliding door by the closer is an elastic force of a spring such as a coil spring provided inside the closer.

Methodology Applied

Scientific EffectElastic force: Elasticity

Implementation Method 2

A damper is incorporated in the closer such that the sliding door opens and closes slowly and quietly.

Methodology Applied

Scientific EffectDamping: Damping

AI summary

Provided is a sliding door closer set which makes it possible to adjust the position of a trigger arranged inside a door pocket from outside of the door pocket. A sliding door closer set comprises a rail (4), a closer (6) hanging a sliding door (1) and being capable of moving along the rail (4), and a trigger (8) arranged inside the door pocket (2), wherein the sliding door (1) is pulled into the door pocket (2) as a result of engagement between the trigger (8) and the closer (6), which has moved to a predetermined position on the rail (4). The trigger (8) arranged inside the door pocket (2) is integrally connected to a trigger integrated plate (10). The trigger integrated plate (10) is mounted to the rail (4) outside the door pocket (2).
