Polygonal Bracket Retainer for Single-Point Fitting Mounting Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing holders for hygiene items require two wall connections for stable mounting, which limits their installation flexibility and visibility.
Innovation Solution
A holder design that utilizes a multi-sided bracket engaging with a single wall connection, such as a polygonal element of a fitting, and includes adjustable features like a base body and insert for alignment, along with a retaining bracket for stability, allowing secure attachment without a second connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a holder is designed to be mounted on two wall connections for stable mounting, then the stability and reliability of the holder is improved, but the device complexity and visual obtrusiveness increases
Solution Approach 1:
The mounting function is segmented into two independent mechanisms: a polygonal bracket that engages with the first wall connection fitting, and a retaining bracket that prevents rotation. This segmentation allows each component to perform its specific function efficiently, enabling stable mounting with only one wall connection instead of requiring two connections.
Solution Approach 2:
The polygonal bracket acts as an intermediary element between the holder and the wall connection fitting. Its multi-sided geometry provides positive engagement with the fitting, translating the single wall connection into a stable mounting point that prevents both displacement and rotation, eliminating the need for a second wall connection.
2Adaptability or versatility
If a polygonal bracket with multi-sided shape is used to engage with wall connection fittings, then the adaptability to different fitting geometries is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The bracket employs an asymmetric polygonal geometry with specifically designed internal angles (e.g., 120° angles for hexagonal engagement) that correspond to common fitting geometries. This asymmetric design provides precise positive engagement with standard fittings while maintaining manufacturing feasibility, as the specific angular relationships are optimized for both adaptability and production.
Solution Approach 2:
The polygonal bracket can be manufactured with different geometric parameters to match various fitting types. By changing the number of sides and internal angles of the polygonal engagement surfaces, the same basic bracket design can adapt to different fitting geometries (hexagonal, rectangular, etc.) without requiring completely different designs, balancing versatility with manufacturing simplicity.
3Ease of operation
If an adjustable insert mechanism is added to the bracket to enable rotation adjustment, then the ease of operation for alignment is improved, but the device complexity increases
Solution Approach 1:
The bracket incorporates a dynamic adjustment mechanism that allows the insert to rotate relative to the base body during installation. This dynamic capability enables users to align the holder shelf horizontally by rotating the insert to match the angular position of the wall connection fitting, after which the insert can be fixed in place. The adjustability is provided only during installation, not during normal operation, maintaining simplicity while improving ease of installation.

AI summary
A bracket (1), which can be detachably mounted on a wall connection (4) located on a wall (12) for a surface-mounted fitting (2), has a shelf (7) extending approximately horizontally in the operating position for objects, e.g., hygiene products, and a bracket (3) connected to the shelf (7), preferably adjustable, which extends at least partially in a plane (11) that is approximately perpendicular to the shelf (7) and parallel to the wall (12). The bracket (3) has a retaining surface (23) with which it can be placed on the wall connection (4). To prevent the bracket (1) from rotating on the surface-mounted fitting (2), the retaining surface (23) has a multi-sided shape with which the bracket (3) can be positively engaged with a part of the surface-mounted fitting (2).
