Inspectable Trap With Extractable Filter for Wall-Side Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional traps under washbasins pose inspection challenges due to their proximity to walls, requiring disassembly and making it difficult for inexperienced users to access and maintain.
Innovation Solution
A trap design with an extractable filtering element accessible from the front or side, allowing easy removal and insertion without disassembling parts adjacent to the wall, facilitating inspection and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the trap is arranged close to the wall to save space for the drawer, then the drawer capacity is improved, but the inspectability of the trap deteriorates
Solution Approach 1:
The trap body is divided into two separate parts: a first part connected to the wall-mounted drain and a second part connected to the washbasin drain. This segmentation allows the first part to be positioned close to the wall for space optimization while the second part extends toward the center for accessibility, resolving the contradiction between drawer capacity and inspectability.
Solution Approach 2:
A connection piece serves as an intermediary element between the first part and second part of the trap body. This mediator allows the trap to maintain its space-saving configuration near the wall while providing access points for inspection through the connection piece that protrudes into the cabinet space.
2Area of stationary object
If the trap is arranged close to the wall, then space is optimized, but access for inspection becomes difficult requiring disassembly
Solution Approach 1:
By segmenting the trap body into multiple parts with the connection piece extending into accessible cabinet space, the design maintains compact wall-side positioning while creating accessible inspection points that do not require disassembly of wall-mounted components.
Solution Approach 2:
The connection piece extends the trap structure into a different spatial dimension (from the wall plane toward the cabinet center), creating access points in three-dimensional space that are reachable from the front without requiring disassembly of the wall-mounted portion.
3Length of moving object
If the trap is positioned to allow drawer installation, then drawer dimensions are improved, but the trap becomes difficult to reach for maintenance
Solution Approach 1:
The trap body is segmented so that the second part connected to the washbasin drain can be positioned more centrally for accessibility, while the first part remains wall-adjacent for space optimization. This allows standard drawer dimensions while maintaining maintenance accessibility.
Solution Approach 2:
The connection piece acts as an intermediary that bridges the gap between the wall-mounted first part and the centrally-positioned second part, allowing the trap to span across the cabinet space and remain accessible from the front while enabling compact drawer design.

AI summary
An inspectable trap (1), comprising a trap body (2) adapted to be connected at one end to a drain (30) of a washbasin (5) or the like and at the opposite end to a wall-mounted drain; the peculiarity of which consists in that the trap body (2) comprises a portion arranged downstream of the drain (30) of the washbasin (5) and provided with an opening (6) adapted to accommodate an extractable filtering element (7).
