Solution Overview

Problem

Current support and anchorage devices for sliding doors face challenges in positioning and removing the door-pin device within the guide profile, require difficult manual alignment, and can lead to loosening and noise due to instability.

Innovation Solution

A mechanical hooking system using a protruding fixing tooth hinged on a sliding body within a metallic section bar, with a dowel screw that supports and locks the tooth in a slit, allowing easy insertion and removal without alignment issues.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional support and anchorage devices are used, then the door panel can be supported, but the positioning and removal of the door-pin device within the guide profile is difficult and requires manual alignment

Engineering Contradiction:
Improvepositioning and removal of door-pin deviceVSAvoidalignment requirements
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The invention inverts the conventional approach by making the door-pin device movable within the guide profile rather than fixed. The movable bracket with sliding mechanism allows the door-pin to be easily positioned and removed without manual alignment, transforming a complex alignment task into a simple sliding operation.

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The door-pin device is made dynamic through the movable bracket that can slide within the guide profile. This dynamic capability allows easy adjustment and removal of the door-pin without requiring precise manual alignment, converting a static alignment problem into a dynamic positioning solution.

Inventive Principle:
Principle #15Dynamics

2Reliability

If conventional anchorage devices are used, then the door panel can be anchored, but loosening and noise occur due to instability during use

Engineering Contradiction:
Improveanchorage stabilityVSAvoidloosening and noise
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The invention applies preliminary action by pre-positioning the door-pin device in optimal locations within the guide profile. The movable bracket allows the door-pin to be initially placed in positions that ensure stable anchorage, preventing loosening and noise before they occur during door operation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The movable bracket mechanism provides feedback capability, allowing the door-pin device to be adjusted during use if loosening or instability occurs. This enables correction of anchorage issues and maintains stable operation, preventing noise and further loosening.

Inventive Principle:
Principle #23Feedback

3Ease of manufacture

If the door-pin device is made movable for easy positioning, then installation is simplified, but the resistance against sliding may be reduced

Engineering Contradiction:
Improveinstallation simplicityVSAvoidresistance against sliding
Core Design Contradiction:
Ease of manufactureVSStrength

Solution Approach 1:

The invention segments the anchorage system into a movable bracket and a door-pin device. This segmentation allows easy installation through simple sliding while maintaining strong resistance against sliding through the specialized design of the door-pin that engages with the guide profile when positioned.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention changes the parameter of mobility from the door-pin device itself to the bracket holding it. This allows the bracket to slide for easy installation while the door-pin maintains its anchorage strength when engaged, separating the mobility function from the anchorage strength function.

Inventive Principle:
Principle #35Parameter changes

AI summary

Device for the support and anchorage (10) in a hanging condition of the door panel (20) in a counter-frame for sliding doors, which consists of a mechanical hooking obtained by means of a protruding fixing movable tooth (130, 140) which is hinged on a body (110) which slides within a metallic section bar (100) and is left to fall unscrewing a dowel screw (150) which supports it, entering a slit (101) obtained in the fixed section bar (100) to be then locked by the same dowel screw (150) which prevents the exit from said slit (101).
