Height-Adjustable Collector for Screen Device Water Tightness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screen devices face challenges in ensuring watertightness at the connection between the spout-shaped piece and the collector, particularly due to the risk of seal damage during tensioning and misalignment of components, which affects both functionality and aesthetics.
Innovation Solution
The collector is designed to be height-adjustable at multiple points, allowing for precise alignment and connection to the spout-shaped piece without damaging the seal, using a fastening body with adjusting screws and a sealant with a raised edge to prevent damage and ensure proper sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the collector is tensioned against the spout-shaped piece to ensure water tightness, then the sealing is improved, but the seal often gets damaged
Solution Approach 1:
The collector is made height-adjustable at multiple points, transforming a static connection into a dynamic, adaptable system. This allows the collector to be positioned precisely before tensioning, reducing excessive force on the seal while maintaining water tightness.
Solution Approach 2:
The height-adjustable mechanism allows preliminary positioning and alignment of the collector with the spout-shaped piece before final tensioning. This preliminary action ensures proper alignment, preventing seal damage during the tensioning process.
2Reliability
If the collector is tensioned against the spout-shaped piece to ensure water tightness, then the sealing is improved, but the aesthetic connection is compromised
Solution Approach 1:
The height-adjustable collector allows for dynamic positioning to achieve both functional sealing and aesthetic alignment. The collector can be adjusted to match the visual line of the beam and column connections while maintaining water tightness.
3Reliability
If the accuracy of placement of adjacent construction elements is increased to procure water tightness, then the sealing is improved, but the assembly complexity increases
Solution Approach 1:
The height-adjustable collector compensates for placement inaccuracies in adjacent construction elements, reducing the need for extremely precise assembly. The adjustability absorbs minor variations in beam and column positioning while maintaining water tightness.
Solution Approach 2:
The collector's height position is made variable through the adjusting screws, allowing parameter adjustment to compensate for placement tolerances. This reduces the stringency of placement accuracy requirements while maintaining sealing effectiveness.
