Flush Mounting Box Removable Flange Watertight Seal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flush mounting boxes struggle to achieve a watertight seal on uneven wall surfaces, leading to potential water penetration due to uneven compression of the seal between the cover and the wall.
Innovation Solution
A flush mounting box design featuring a removable flange with a watertight connection to the mounting box, utilizing a frame shape with a smooth rear side and optional groove for additional sealing, and an adhesive or plastic weld for secure attachment, allowing for easy adaptation to uneven surfaces and easy removal without damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an elastic seal is installed between the cover and the wall to create a dustproof and watertight seal, then dustproof and watertight properties are improved, but on uneven wall surfaces the seal does not compress evenly leading to water penetration risk
Solution Approach 1:
The seal is segmented into multiple independent compression points along its circumference, allowing each segment to adapt to local variations in wall surface unevenness. This segmentation enables the seal to maintain contact and compression effectiveness across irregular surfaces without requiring uniform compression across the entire seal length.
Solution Approach 2:
The seal design incorporates local quality variations where different segments of the seal can have different compression characteristics. This allows the seal to provide enhanced compression at specific critical points while maintaining adequate sealing elsewhere, adapting to the local geometry of uneven wall surfaces.
2Reliability
If a flange is fixed to the mounting box with a watertight connection to ensure waterproofness, then waterproofness is improved, but the flange cannot be easily removed for adaptation or conversion
Solution Approach 1:
The flange incorporates pre-formed separation features such as break lines or weakened bonds that allow for controlled removal after the watertight seal has been established. This preliminary design enables the flange to maintain its sealing function during installation while allowing easy removal later for adaptation or conversion to reduced form.
Solution Approach 2:
The flange is designed as a sacrificial or removable component that can be discarded or separated from the mounting box after serving its primary sealing and mounting function. This allows the mounting box to be converted to a reduced form for other applications while the flange can be removed without damage to the main body.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution ensures a reliable waterproof seal on both even and uneven surfaces, enhancing dustproof and watertight properties, and allows for conversion into a reduced form for various applications while maintaining mechanical strength and standard dimensions.
Implementation Method 1
The mounting flange is secured via a watertight connection, e.g. an adhesive bond or weld, to the open end
Implementation Method 2
The mounting flange and flush mounting element are made of plastic and the watertight seal is created by a plastic weld
Implementation Method 3
an elastic seal is installed between the cover and the wall. This seal is slightly compressed between the cover and the wall as the cover is secured thus creating a more or less dustproof and watertight seal

AI summary
Box assembly to be installed in a wall and intended to house electrical components, which comprises the following: - a hollow flush mounting element that can be mounted in a wall opening and is intended to create a space in which electrical components can be inserted, at least partially; - a mounting flange facing outward, designed to extend around the wall opening once mounted, and fixed to the hollow flush mounting element with a watertight seal that can, to a large extent, be removed with one or more specific post processing operations.
