Screen Guide Intermediate Detachment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screen guides cannot engage and detach from a support rail at an intermediate position, limiting their functionality in screen devices that operate by moving side to side within a screen frame.
Innovation Solution
A screen guide system with guide pieces and engagement members that can rotate to engage and detach from a support rail with opposing edges, allowing engagement and detachment at intermediate positions, ensuring secure support and operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the engagement hooks are positioned to always engage the engagement edges from an end portion of the rail, then the screen guide can be securely supported, but the screen guide cannot be detached at an intermediate position on the rail
Solution Approach 1:
The engagement member is designed to rotate about an axis, transitioning between a locked position where engagement hooks engage the engagement edges for secure support, and an unlocked position where the hooks disengage from the edges, enabling detachment at intermediate positions on the rail
Solution Approach 2:
The engagement member is divided into distinct functional components: engagement hooks for securing, a rotation axis for movement control, and positioning mechanisms that allow selective engagement at different locations along the rail, enabling both secure support and intermediate detachment

AI summary
There is provided a screen guide that engages a support rail or is detachable from the support rail at an intermediate position on the support rail. The support rail supports the screen guide and includes first and second engagement edges, and the screen guide is formed by connecting a plurality of guide pieces to one another in series. Each of the guide pieces includes a piece body that engages an end portion of a screen and an engagement member that includes first and second engagement portions that engage the first and second engagement edges of the support rail, respectively. Each of the engagement members is coupled to the corresponding piece body such that the engagement member is capable of being displaced to a first position at which the first and second engagement portions engage the first and second engagement edges, respectively, and to a second, detached position.
