Overflow Drain Assembly External Adapter Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing basin and overflow or drain assemblies face challenges in assembly complexity, particularly with screw connections from the interior of the basin, leading to potential damage, leaks, and the need for multiple spare parts due to varying basin designs.
Innovation Solution
The assembly uses an adapter element fixed to the basin wall externally, allowing the overflow or drain body to be coupled via a mechanism like a snap or bayonet connection from outside the basin, eliminating the need for internal screwing and enabling compatibility with different basin designs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screw connection from interior of basin is used to attach overflow or drain body, then secure attachment is achieved, but risk of damage to basin interior and complexity of installation increases
Solution Approach 1:
The patent inverts the conventional installation approach by attaching the adapter element to the exterior of the basin wall rather than from the interior. This allows the overflow or drain body to be secured without inserting screws into the basin interior, thereby eliminating the risk of scratching or damaging the basin surface while maintaining secure attachment through the adapter element's external mounting and internal locking mechanism.
2Reliability
If screw connection from interior of basin is used, then attachment is achieved, but installation time and difficulty increase
Solution Approach 1:
The patent segments the attachment system into two distinct components: an adapter element that is pre-fixed to the basin wall exterior, and an overflow or drain body that is subsequently attached. This segmentation allows the adapter element to be installed once and reused across multiple installations, while the overflow or drain body can be quickly attached or detached using simple locking elements without requiring complex screwing operations from the basin interior, significantly reducing installation time and complexity.
3Adaptability or versatility
If adapter element is used to create standardized interface, then compatibility with different basin designs is improved, but device complexity increases
Solution Approach 1:
The patent introduces an adapter element as an intermediary component between the basin wall and the overflow or drain body. This adapter element provides a standardized interface that can be universally attached to different basin designs through its exterior mounting capability, while its internal structure accommodates various overflow or drain body types. The intermediary adapter simplifies the overall system by decoupling the basin-specific attachment requirements from the standardized overflow/drain body interface.

AI summary
In order to create an overflow or drain assembly for a basin which can be installed in a simple and reliable manner without requiring screwing from the interior of the basin, it is proposed that the overflow or drain assembly comprise an adapter element which can be arranged on a basin wall of the basin in the area of an overflow or drain opening, and an overflow or drain body which has an inlet opening for liquid passing through the overflow or drain opening and which can be coupled to the adapter element from a side of the adapter element facing away from the interior of the basin when the adapter element is arranged on the basin wall.
