Telescopic Chain Handling for Wide Lateral Sliding Shields
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing handling systems for lateral sliding shields require that the height of the screen to be greater than its width, limiting their use in wide openings where the screen width exceeds the height.
Innovation Solution
A telescopic handling system with a chain formed by interconnected first and second elements, allowing telescopic collapse and guided motion, enabling the screen to be fully extended beyond the handle bar while being retracted.

Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional chain mechanism is used for lateral sliding shields, then the chain can be housed within the handle bar, but the screen height must be greater than its width
Solution Approach 1:
The chain is divided into multiple articulated elements (first elements with upper surfaces and lateral surfaces, second elements with corresponding surfaces) that can telescope relative to each other. This segmentation allows the chain to collapse into a compact configuration that fits within the handle bar while supporting screens with width greater than height.
Solution Approach 2:
The telescopic chain elements are designed to nest within each other during retraction. The second elements are received inside the contiguous first elements, creating a nested configuration that reduces the overall chain length when stored in the handle bar, thereby enabling use with wide screens.
2Length of moving object
If the chain length is reduced to fit within the handle bar, then the chain can be stored compactly, but the screen width is limited
Solution Approach 1:
The chain transitions from a static fixed-length structure to a dynamic telescopic structure. The articulated elements can extend to provide sufficient length for wide screens during operation, then collapse to a compact nested configuration for storage within the handle bar, effectively decoupling the chain's operational length from its storage length.
Solution Approach 2:
The chain elements utilize three-dimensional articulation and telescoping motion rather than simple linear extension. The first and second elements connect through multiple surfaces (upper, lateral) allowing movement in multiple dimensions, enabling the chain to achieve both extended length for wide screens and compact retraction for handle bar storage.
