Cup-Sealed Device Frame for Flat Moisture-Protected Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Moisture-protected device frames for surface-mounting require a low installation height, limiting the available space for electrical device inserts and connection components, which is inadequate for complex devices like door intercom systems with additional functionalities that are sensitive to moisture.
Innovation Solution
A cup-shaped sealing element is integrated into the device frame, expanding the installation space by its volume and providing a fluid-sealing connection, which can be fixed via a frictional connection and engages with a circumferential groove to secure the sealing element, allowing for additional moisture protection and flexibility to accommodate larger components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the device frame is designed with a low installation height for aesthetic reasons, then the flat design and aesthetic appearance are improved, but the installation space for device inserts and connection components becomes insufficient
Solution Approach 1:
The patent extends the installation space in the depth dimension by introducing a cup-shaped sealing element that protrudes into the building wall recess. This allows the device frame to maintain a low profile at the visible surface while providing sufficient installation volume through the depth dimension, effectively resolving the contradiction between flat design and adequate installation space.
2Volume of moving object
If the device frame provides sufficient installation space for complex device inserts, then the functionality and moisture protection are improved, but the installation height increases compromising the flat design
Solution Approach 1:
The patent segments the installation space into two distinct zones: a shallow installation space within the device frame for the device insert, and a deeper extension space within the cup-shaped sealing element for connection components. This segmentation allows each zone to be optimized independently, maintaining the flat appearance of the device frame while providing sufficient space for complex installations.
3Ease of operation
If the cup-shaped sealing element is made flexible to accommodate cable installations, then the ease of installation is improved, but the sealing reliability may be compromised
Solution Approach 1:
The cup-shaped sealing element is constructed as a composite structure combining a flexible outer layer for ease of installation and cable accommodation with an integrated rigid reinforcing ring for structural stability and sealing reliability. This composite design allows the sealing element to be compressed during installation while maintaining its sealing integrity and preventing deformation that would compromise moisture protection.
