Solution Overview

Problem

Existing sliding door railings require two operators for installation due to the need for tools and precise positioning, leading to inefficiencies and potential installation errors.

Innovation Solution

A protective sliding door with a detachable positioning mechanism and locking mechanism that allows single-person installation, featuring a pivot connection side with a connecting piece for easy assembly and a locking mechanism for secure closure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If hinge seat or pivot structure is directly installed on sliding door railing, then structural stability is improved, but installation complexity increases requiring two operators

Engineering Contradiction:
Improvestructural stabilityVSAvoidinstallation complexity
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The invention divides the installation process into two independent stages: first installing the hinge seat/pivot structure on the wall, then separately installing the sliding door railing body. The detachable connection structure allows the railing body to be connected to the pre-installed hinge seat after positioning, enabling single-person installation while maintaining structural stability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The hinge seat or pivot structure is installed on the wall in advance before the sliding door railing body is attached. This preliminary installation provides a fixed reference point that simplifies the subsequent connection process, allowing the railing to be easily positioned and connected by a single operator.

Inventive Principle:
Principle #10Preliminary action

2Manufacturing precision

If tools are used for installation and fixation while maintaining correct position, then installation precision is improved, but installation time increases

Engineering Contradiction:
Improveinstallation precisionVSAvoidinstallation time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The detachable connection structure incorporates self-positioning features that automatically guide the railing body into the correct position during connection to the pre-installed hinge seat. This self-aligning mechanism eliminates the need for continuous tool-based adjustments, allowing rapid connection while maintaining precise positioning.

Inventive Principle:
Principle #25Self-service

3Manufacturing precision

If sliding door railing is securely supported during installation, then installation quality is improved, but single-person operation becomes difficult

Engineering Contradiction:
Improveinstallation qualityVSAvoidsingle-person operation
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The installation system is segmented into a fixed wall-mounted hinge seat and a movable railing body with detachable connection. This separation allows the heavy railing body to be independently positioned and connected without requiring continuous support from a second person, as the detachable connection provides inherent stability during the connection process.

Inventive Principle:
Principle #1Segmentation
