Beam Assembly Sealing Profile for Screen Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screen device connections between beam elements and structural elements, such as external walls, face challenges in achieving a reliable watertight seal due to uneven structural surfaces and the need for repeated sealing, especially when the beam element's cavity must remain accessible.
Innovation Solution
A beam assembly featuring a connecting profile with a fitting groove for precise sealing, a drainage profile to manage precipitation, and an upright flange to ensure watertightness, allowing for easy application and longevity of the sealing means, even on uneven surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sealing agent is applied to seal the connection between beam element and structural element, then watertightness is improved, but reliability deteriorates due to uneven structural surfaces causing inadequate sealing
Solution Approach 1:
A connecting profile is introduced as an intermediary component between the beam element and the structural element. This connecting profile includes a fitting groove that receives the sealing agent, creating a controlled interface that mediates the connection between the beam and the uneven structural surface, thereby ensuring reliable sealing despite surface irregularities
Solution Approach 2:
The sealing approach transitions from direct application to the structural element to application within a defined fitting groove of the connecting profile. This parameter change in sealing location and geometry ensures consistent sealing thickness and position, improving both manufacturing precision and reliability
2Reliability
If sealing profile is used to protect cavity, then cavity protection is improved, but ease of operation deteriorates due to repeated sealing removal and reapplication
Solution Approach 1:
The beam assembly is segmented into distinct functional components: the beam element with accessible cavity, the connecting profile with fitting groove for sealing, and the drainage profile. This segmentation allows the sealing to be applied once at the connecting profile during initial installation and remains stable throughout the service life, eliminating repeated removal and reapplication
3Object-affected harmful factors
If drainage profile is added to drain precipitation, then protection against precipitation is improved, but device complexity increases
Solution Approach 1:
The drainage function is merged with the existing connecting profile structure. The drainage profile integrates with the connecting profile's fitting groove and upright flange, combining drainage functionality with the sealing and structural connection functions in a unified assembly, thereby limiting the increase in overall device complexity
