Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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
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
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
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
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
3Ease of operation
If pre-assembled double trussed panels are used, then transportation convenience is improved, but handling difficulty and connection stability worsen
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
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
