Solution Overview

Problem

Existing enclosure systems with sliding panels face issues such as increased cost, visual impact, reduced airtightness, and potential breakage of swivel mechanisms due to manual alignment errors during door panel opening, particularly in utility model ES-1179533-U.

Innovation Solution

The introduction of pulling means that couple to a mobile profile and a door panel, ensuring synchronized movement by using a filiform element to guide the door panel into the correct position, reducing manual manipulation and potential damage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual alignment is used to move the door panel to the correct position, then the door panel can be opened, but the swivel mechanism may break due to forced movement and alignment errors

Engineering Contradiction:
Improvedoor panel openingVSAvoidswivel mechanism
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The mobile profile performs preliminary action by automatically pulling the door panel to the correct position before the swivel mechanism is engaged. This preliminary positioning action eliminates the need for manual alignment and prevents forced movement, thereby protecting the swivel mechanism from damage while maintaining ease of operation.

Inventive Principle:
Principle #10Preliminary action

2Device complexity

If a fixed door panel configuration is used, then the system structure is simple, but additional components are needed which increases cost and reduces airtightness

Engineering Contradiction:
Improvedoor panel structureVSAvoidairtightness
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The mobile profile serves multiple functions: it acts as both a locking mechanism and a positioning device that pulls the door panel into correct alignment. This multi-functionality eliminates the need for separate alignment components, maintaining structural simplicity while ensuring proper door panel positioning for airtightness.

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

3Device complexity

If the mobile profile retracts within the fixed profile, then the locking device is compact, but the door panel does not open and must be manually moved which causes alignment errors

Engineering Contradiction:
Improvelocking device compactnessVSAvoiddoor panel positioning
Core Design Contradiction:
Device complexityVSManufacturing precision

Solution Approach 1:

The pulling means acts as an intermediary element between the mobile profile and the door panel. When the mobile profile retracts, it uses this intermediary pulling mechanism to automatically move the door panel to the correct position, thereby maintaining compact locking device design while achieving precise door panel positioning without manual intervention.

Inventive Principle:
Principle #24Intermediary (Mediator)
