Lotion dispenser for bathrooms and sanitary facilities
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lotion dispensers for bathrooms require exact matching of wall niche dimensions and protruding flanges for secure installation, leading to installation challenges, maintenance needs, and aesthetic issues with different wall material thicknesses.
Innovation Solution
A lotion dispenser comprising a flush-mounting box, an adjustable flange frame that surrounds the box, and a built-in module, allowing for 'floating' installation and adaptation to varying wall material thicknesses, ensuring a flush surface and eliminating the need for grouting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a surrounding flange is used for secure installation, then installation stability is improved, but the flange protrudes above the wall covering causing aesthetic issues and cleaning difficulties
Solution Approach 1:
The device is divided into two main components: a mounting box for secure installation in the wall niche and a separate front panel that provides the functional interface. This segmentation allows the mounting box to be securely fixed while the front panel remains flush with the wall covering surface, eliminating protruding flanges and facilitating easy cleaning of the wall surface.
2Stability of the object's composition
If exact matching of wall niche dimensions is required, then installation security is improved, but adaptability to different wall niches and wall covering thicknesses deteriorates
Solution Approach 1:
The mounting box is designed with universal adaptability to accommodate different wall niche dimensions and wall covering thicknesses. It features adjustable mounting elements that can be positioned at various depths, allowing the same mounting box to be securely installed in diverse wall configurations without requiring exact dimensional matching, thereby providing both installation security and broad adaptability.
3Stability of the object's composition
If a surrounding flange is used for secure installation, then installation stability is improved, but maintenance requirements increase due to sealing needs in wet areas
Solution Approach 1:
The problematic surrounding flange that required sealing and maintenance is extracted from the design. Instead, a mounting box system is used that secures the device in the wall niche without protruding flanges, eliminating the need for silicone adhesive sealing and subsequent maintenance while maintaining installation stability through the mounting box's secure fixation mechanism.
4Adaptability or versatility
If the mounting box is positioned floating in the wall niche, then adaptability to different wall covering thicknesses is improved, but installation precision deteriorates
Solution Approach 1:
The mounting box incorporates dynamic adjustment mechanisms that allow installers to adapt the mounting depth and position according to the specific wall covering thickness. This dynamic capability enables the mounting box to be securely fixed at the appropriate depth for various wall covering materials (tiles, porcelain stoneware, natural stone) while maintaining precise alignment and flush installation with the wall surface.

AI summary
The disclosed lotion dispenser for bathrooms and sanitary facilities is to be mounted in a recess in a wall and has to only approximately match the dimensions of the recess in the wall. The disclosed lotion dispenser can be mounted flush with the wall cover regardless of the thickness of the wall cover. For this purpose, the lotion dispenser has the following features: - a flanged frame (2) which can be joined to the surrounding wall structure (6) of the recess (5) in the wall, surrounds the concealed mounting box (1) and is adjustably connected thereto; and - a mounting module (4) for accommodating containers of lotion behind a cover (8) that is flush with the surface, said mounting module (4) being inserted into the concealed mounting box (1) and covering the free ends of the concealed mounting box (1) in a flush manner by means of a peripheral flange (7a). The flanged frame (2) is to be mounted underneath the wall cover (3) of the wall structure (6). By adjusting the flanged frame (2) on the concealed mounting box (1), the mounting depth of the concealed mounting box (1) can be adjusted to different thicknesses of the wall cover (3) in such a way that the mounting module (4) inserted into the concealed mounting box (1) is flush with the surface of the wall cover (3).
