Solution Overview

Problem

Traditional sliding door railings with monotonous structures and operations fail to capture consumer attention and interest, and their installation and removal are not efficient.

Innovation Solution

A new type of sliding door railing with a first and second connecting mechanism, allowing the door railing body to pivotally connect to both mechanisms, enabling quick disconnection and reconnection for easy installation and removal, utilizing expansion members and top springs for elastic force to maintain detachable fits.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a single-side opening door structure is used with pivot structure on one side and locking structure on the other side, then the door railing can be installed and locked, but the structure becomes monotonous and fails to capture consumer attention

Engineering Contradiction:
Improveinstallation simplicityVSAvoidoperational versatility
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent applies asymmetry by providing different connecting mechanisms at opposite sides of the door railing body - a first connecting mechanism with pivot structure on one side, and a second connecting mechanism with locking structure on the other side. This asymmetric configuration enables the door railing to have both single-side opening capability and enhanced operational versatility through the ability to be installed in different configurations.

Inventive Principle:
Principle #4Asymmetry

Solution Approach 2:

The patent implements universality by designing the door railing with multiple connecting mechanisms that can perform different functions. The first connecting mechanism provides pivot-based opening/closing, while the second connecting mechanism provides locking capability. This multi-functional design allows the same door railing structure to serve multiple purposes and adapt to different operational requirements, making it more versatile and attractive to consumers.

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

2Reliability

If traditional sliding door railing is installed, then it provides basic door protection function, but it cannot be quickly removed when needed

Engineering Contradiction:
Improvedoor protection functionVSAvoidremoval convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent applies segmentation by dividing the door railing into separable components connected through detachable connecting mechanisms. The door railing body can be disconnected from the first and second connecting mechanisms, allowing the structure to be divided into separate parts that can be easily removed and reinstalled. This segmented design maintains the reliability of door protection when installed while enabling quick removal when needed.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements dynamics by incorporating detachable and adjustable connecting mechanisms that allow the door railing to transition between installed and removed states. The first connecting mechanism with pivot structure and the second connecting mechanism with locking structure can be selectively engaged or disengaged, providing dynamic adaptability. This enables the door railing to be quickly installed or removed based on operational needs while maintaining secure protection when in place.

Inventive Principle:
Principle #15Dynamics
