Wedge Adapter Mounting for Angled Wall-Hung WC Basins
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wall-mounted toilet bowls have limited installation options, restricting flexibility and access due to fixed perpendicular or parallel alignment, which is not possible with free-standing models.
Innovation Solution
An adapter with wedge surfaces and contact surfaces, made of coated sheet steel, allowing for adjustable mounting angles between 10° and 45°, enabling more flexible installation by forming a closed hollow body with bushings for water lines and fastening openings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a toilet bowl is wall-mounted with fixed perpendicular or parallel alignment, then structural stability is ensured, but installation flexibility and access are restricted
Solution Approach 1:
The mounting system is divided into separate components: a wall mounting plate and an adapter piece that connects to the toilet bowl. This segmentation allows each component to be optimized independently - the mounting plate provides stable wall attachment while the adapter enables angle adjustment, thus improving installation flexibility without compromising structural stability.
Solution Approach 2:
The adapter incorporates adjustable mechanisms that allow the mounting angle to be dynamically changed during installation. The adapter can be positioned at different angles relative to the wall mounting plate, enabling the toilet bowl to be installed at various orientations (perpendicular, parallel, or angled) while maintaining secure structural connection.
2Ease of operation
If the distance to the parallel wall is increased for adequate access, then access to the toilet bowl is improved, but space utilization is reduced
Solution Approach 1:
The adjustable adapter allows the toilet bowl to be positioned at optimal angles relative to the walls, enabling better access without requiring excessive distance from parallel walls. By changing the mounting angle, the bowl can be oriented to maximize accessibility while minimizing the space it occupies in the room.
Solution Approach 2:
Instead of only providing perpendicular or parallel mounting options, the adapter introduces angular mounting capability, adding a new dimension of adjustment. This allows the toilet bowl to be positioned at intermediate angles that optimize both accessibility and space utilization according to the specific room layout.
3Adaptability or versatility
If free-standing toilet bowls are aligned at an angle to the walls, then installation flexibility is improved, but this option becomes unavailable when wall-mounted
Solution Approach 1:
By separating the wall mounting function from the angle adjustment function into distinct components (mounting plate and adapter), the system enables angular positioning similar to free-standing bowls while maintaining the structural advantages of wall-mounted installation. The adapter absorbs the angular adjustment requirements, allowing the wall mounting plate to focus on providing stable attachment.
Solution Approach 2:
The adapter acts as an intermediary component between the wall mounting plate and the toilet bowl. It transfers and distributes the mechanical loads from angular positioning and bowl weight to the wall mounting structure, enabling angle adjustment while maintaining wall mounting stability through proper load distribution.

AI summary
2.1 The application concerns a device for wall mounting a toilet bowl. 2.2 This device consists of a wedge-shaped adapter, designed as a closed hollow body with two large contact surfaces and wedge surfaces connecting these surfaces such that the two large contact surfaces face each other at an angle defined by the wedge surfaces, one of these surfaces serving as the contact and mounting surface of the adapter on the wall and the other surface as the contact and mounting surface for the toilet bowl, and the two contact surfaces having recesses aligned with each other for the passage of the fresh water and wastewater pipes.
