Detachable Screen Tension Connectors for Pleated Blind Doors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing screen apparatus requires complete removal and reinstallation for screen interchange, which is time-consuming and labor-intensive due to the fixed connection of screen tension members with the slide guide frame portion.
Innovation Solution
The screen apparatus incorporates detachable connectors and fold-back portions that allow the screen to be interchanged without removing the entire apparatus, enabling easy detachment and reattachment of the screen tension members, facilitating screen interchange at the installation site.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the screen tension members are fixedly connected to the slide guide frame portion, then the structural stability is improved, but the ease of screen interchange deteriorates
Solution Approach 1:
The screen tension member is divided into multiple segments: the first connector portion, the intermediate portion, and the second connector portion. The detachable connector is segmented into a connector body and a detachable connector portion. This segmentation allows the screen tension member to maintain structural stability when connected while enabling easy detachment and interchange of the screen without removing the entire apparatus.
Solution Approach 2:
The connection between the screen tension member and the slide guide frame portion transitions from a fixed static connection to a dynamic detachable connection. The detachable connector allows the connection state to change between connected and detached, providing both structural stability during use and ease of interchange during maintenance, thus resolving the contradiction between these two requirements.
2Ease of repair
If the slide guide frame portion is extracted from the screen attaching frame portion for screen interchange, then the ease of screen interchange is improved, but the loss of time increases
Solution Approach 1:
The detachable connector portion is extracted from the slide guide frame portion and made separable. This allows the screen tension member to be detached from the slide guide frame portion without extracting the entire slide guide frame portion from the screen attaching frame portion, significantly reducing the time required for screen interchange while maintaining ease of repair.
Solution Approach 2:
The detachable connector is segmented into a connector body that remains with the slide guide frame portion and a detachable connector portion that moves with the screen tension member. This segmentation enables partial detachment (only the connector portion) rather than complete extraction, reducing the time loss associated with screen interchange.
3Ease of repair
If the screen is detachably attached to the screen attaching frame portion, then the ease of screen interchange is improved, but the device complexity increases
Solution Approach 1:
The detachable connector integrates multiple functions into a single component: it provides the connection between the screen tension member and the slide guide frame portion, enables easy detachment and reattachment, and maintains structural stability. This merging reduces device complexity compared to having separate components for each function while still achieving ease of screen interchange.
Solution Approach 2:
The detachable connector serves multiple purposes: it acts as a connection element, a detachment mechanism, and a structural support component. This multi-functionality reduces the overall device complexity by eliminating the need for separate components for each function while maintaining the ability to easily interchange screens.
