Modular Screen Member Gas Spring Height Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screen panels for demarcating outdoor spaces are inefficient as they require seasonal dismantling and reassembly to adjust for wind protection, leading to excessive heating in dry seasons and high manual effort for height adjustment.
Innovation Solution
A modular screen member with a fixed lower panel and an upper panel that slides using gas springs, allowing for easy height adjustment with minimal effort and no dismantling, featuring a lower panel with a rectangular frame and an upper panel with a frame shape that encloses a transparent sheet, enabling positioning at various heights.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screen panels are made as single large elements for effective wind protection, then wind protection effectiveness is improved, but excessive heating occurs during dry season due to greenhouse effect and poor air circulation
Solution Approach 1:
The screen panel is divided into two separate elements: a fixed base element and a movable upper element. This segmentation allows the upper element to be removed during dry season, eliminating the greenhouse effect and poor air circulation problems while maintaining wind protection when both elements are assembled together.
2Reliability
If screen panels are made as single large elements, then wind protection is effective, but complete dismantling and reinstallation is required for seasonal adjustment which is inconvenient
Solution Approach 1:
By dividing the screen into fixed base element and movable upper element, the system allows partial removal of only the upper element for seasonal adjustment, eliminating the need to dismantle and reassemble the entire structure.
Solution Approach 2:
The upper element is designed to be movable relative to the base element through sliding and lifting mechanisms, enabling dynamic adjustment between assembled and separated states for seasonal changes, rather than being fixed in one position.
3Ease of operation
If vertical sliding type screens with lateral pulley systems and counterweights are used to avoid dismantling, then height adjustment is possible, but considerable manual effort is required by the user
Solution Approach 1:
Gas springs are used as counterweight mechanisms to balance the weight of the upper element, reducing the manual effort required for lifting and lowering operations. The gas springs provide upward force to counteract gravity, making height adjustment effortless.
Solution Approach 2:
Gas springs (pneumatic devices) are employed to provide the counterbalancing force needed for height adjustment, replacing mechanical pulley systems and manual counterweights with a more efficient pneumatic mechanism that requires minimal user effort.
4Reliability
If interchangeable upper and lower elements are used for seasonal adjustment, then wind protection can be optimized, but partial dismantling and reassembling of structure is required
Solution Approach 1:
The screen is segmented into a fixed base element and a movable upper element that can be independently removed or assembled. This segmentation simplifies seasonal adjustment to a single-element operation rather than requiring dismantling and reassembly of multiple components.
Solution Approach 2:
The upper element is designed with movable connections (sliding and lifting mechanisms) that allow it to be easily attached to and detached from the base element, reducing the complexity of seasonal adjustments compared to fixed or multi-component interchangeable systems.
