Omega-Shaped Rear Post for Retractable Sliding Door Frames
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for in-wall frames of retractable sliding doors require users to physically shorten components using special tools, which is time-consuming and skill-dependent, limiting ease of adaptation to specific spaces.
Innovation Solution
A Ω-shaped rear post with axial coupling means and temporary locking screws allows for on-site adjustment and secure locking with conventional tools, eliminating the need for special cutting tools and enabling easy adaptation to different dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional metallic profiles are used that require physical shortening to adapt to space dimensions, then the frame can be assembled from standardized components, but the installation process becomes time-consuming and requires special cutting tools and skilled labor
Solution Approach 1:
The rear post is divided into multiple modular sections that can be assembled in different configurations. The post consists of a first section and a second section that can be coupled together, allowing the overall length to be adjusted by selecting different numbers and arrangements of sections, eliminating the need for cutting operations
Solution Approach 2:
The rear post design incorporates adjustable and reconfigurable elements that allow the structure to adapt to different installation requirements. The modular sections can be selectively coupled or uncoupled to change the effective length and configuration of the post, providing dynamic adaptability without requiring permanent modification
2Adaptability or versatility
If standardized metallic profiles are used, then manufacturing and inventory management is simplified, but adaptation to specific site requirements becomes difficult without special tools
Solution Approach 1:
The rear post is segmented into standardized modular sections that maintain consistent connection interfaces. This segmentation allows the same basic components to be assembled in various configurations to achieve different lengths and adapt to different space requirements, providing versatility through simple modular assembly rather than complex customization
Solution Approach 2:
The modular sections of the rear post are designed with universal connection features that allow them to be used in multiple configurations. The same basic section can serve different functions and be combined with other sections in various arrangements, making the system universally adaptable to different installation scenarios without requiring specialized components
