Flush-Mounted Box With Slot Openings For Plumbing Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing kits for fastening sanitary components to an installation wall with water-carrying connection lines are complex and difficult to assemble, especially when the connection lines are not laid in a suitable grid, due to the limited alignment leeway and cumbersome connection process.
Innovation Solution
The through-openings in the flush-mounted box are designed as slots with oblong holes to accommodate the fittings support body, allowing for easier alignment and assembly, with non-rotatable covers and adjustable retaining elements that provide alignment flexibility and stabilization, and a preassembled flushing insert with a screw connection for easy detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the fittings support body is inserted into the flush-mounted box with traditional through-openings, then the connection to wall-side connection lines can be established, but the assembly becomes complex and difficult when connection lines are not laid in a suitable grid
Solution Approach 1:
The through-openings are designed as slots instead of fixed circular openings, allowing the fittings support body to be inserted at various angles and positions. This dynamic adjustment capability enables assembly even when connection lines are not laid in a suitable grid, significantly improving ease of operation while reducing assembly complexity
Solution Approach 2:
The geometry of the through-openings is changed from fixed circular to elongated slot shapes, allowing for parameter variation in insertion angle and position. This design change provides alignment flexibility and accommodates different connection line arrangements, simplifying the overall assembly process
2Reliability
If the fittings support body has a transverse extent smaller than the distance between flat surfaces of the outer wall, then it can be held by sleeve-shaped holding elements, but there is no leeway for aligning the parts
Solution Approach 1:
The slot design in the through-openings introduces dynamic alignment capability, allowing the fittings support body to be positioned and rotated to achieve proper alignment with connection lines. This maintains reliable fixing while providing necessary leeway for alignment during assembly
Solution Approach 2:
The holding elements are designed to engage with the arms of the fittings support body through the slot openings, creating a segmented connection system that allows for adjustment and alignment while maintaining secure fixing. The separation of the holding function from the insertion path enables independent optimization of both reliability and alignment flexibility
3Adaptability or versatility
If the through-openings are designed as slots extending in the circumferential direction, then alignment flexibility is provided, but the structure becomes more complex
Solution Approach 1:
The slot openings are designed as simple elongated shapes rather than complex variable geometry, maintaining structural simplicity while providing alignment flexibility. The segmentation of the opening into basic slot forms avoids unnecessary structural complexity while achieving the desired adaptability for different installation configurations
