Solution Overview

Problem

Conventional sliding doors are cumbersome and costly to transport and assemble due to their fixed structure, and existing solutions either complicate on-site assembly or increase costs.

Innovation Solution

A sliding door arrangement comprising modular door units, upright posts, a lower beam, cross rod assemblies, and connectors that allow for easy disassembly and reassembly, with adjustable tightness and decorative features.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If conventional sliding doors use fixed structures with welding or riveting, then structural strength is improved, but transportation and assembly convenience deteriorates

Engineering Contradiction:
Improvestructural strengthVSAvoidtransportation and assembly convenience
Core Design Contradiction:
StrengthVSEase of operation

Solution Approach 1:

The sliding door is divided into multiple modular components including door bodies, upright posts, cross rods, and connecting pieces. Each component can be independently manufactured and transported, then assembled on-site through simple connection operations without requiring welding or riveting, thus resolving the contradiction between structural strength and transportation/assembly convenience

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The connecting pieces are pre-designed with built-in connection mechanisms that enable direct assembly of modular components. The connection structures are prepared in advance during manufacturing, allowing for quick on-site assembly while maintaining structural integrity, thereby solving the contradiction between strength and assembly convenience

Inventive Principle:
Principle #10Preliminary action

2Stability of the object's composition

If sliding doors are manufactured as large fixed structures, then structural integrity is improved, but packaging and transportation cost increases

Engineering Contradiction:
Improvestructural integrityVSAvoidpackaging and transportation cost
Core Design Contradiction:
Stability of the object's compositionVSQuantity of substance

Solution Approach 1:

The sliding door system is segmented into multiple smaller modular components (door bodies, upright posts, cross rods, connecting pieces) that can be packaged in compact units. This segmentation reduces packaging volume and transportation costs compared to moving a single large fixed structure, while the components are designed to assemble into an integrated whole that maintains structural integrity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The modular components are designed to nest within each other during storage and transportation. For example, cross rods can be stored within door bodies, and connecting pieces can be nested within upright posts, maximizing space utilization and reducing packaging volume, thereby lowering transportation costs while preserving structural integrity

Inventive Principle:
Principle #7Nested doll (Nesting)

3Ease of operation

If pre-assembled double trussed panels are used, then transportation convenience is improved, but handling difficulty and connection stability worsen

Engineering Contradiction:
Improvetransportation convenienceVSAvoidconnection stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

Instead of using large pre-assembled double trussed panels that are difficult to handle, the system is segmented into smaller modular components (door bodies, upright posts, cross rods) that are easier to transport and maneuver. The modular design maintains connection stability through specialized connecting pieces designed for reliable assembly

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Specialized connecting pieces serve as intermediaries between the modular components. These connecting pieces are specifically designed to provide stable and reliable connections between door bodies, upright posts, and cross rods, compensating for the potential instability that might arise from modular construction, thus resolving the contradiction between transportation convenience and connection stability

Inventive Principle:
Principle #24Intermediary (Mediator)
