Shower Drain Box with Adjustable Support Tabs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laying boxes for shower drain fittings are difficult to install on uneven floors and require complex production processes, limiting their adaptability and ease of use.
Innovation Solution
A laying box with laterally protruding tabs that accommodate height-adjustable stands, allowing for precise positioning on uneven surfaces, and featuring connections for wastewater pipes with optional angled configurations and material layers for increased flexibility, along with pivotable and clip-on designs for enhanced adaptability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a two-part laying box with adjustable cover section is used, then the height can be adjusted, but the device complexity increases and manufacturing becomes more difficult
Solution Approach 1:
The laying box is divided into a base section with laterally projecting tabs and a separate cover section, allowing independent adjustment of the cover section relative to the base section to achieve height adjustment while maintaining manufacturing simplicity
Solution Approach 2:
The cover section can be adjusted to different positions relative to the base section using locking means, enabling dynamic height adjustment during installation to accommodate varying subfloor conditions and drainage requirements
2Ease of manufacture
If the cover section is guided over the side walls of the base section, then assembly is simplified, but the laying box cannot be used on uneven subfloors
Solution Approach 1:
Height adjustment is achieved not only through vertical positioning of the cover section but also through lateral extension of the base section via tabs and support legs, adding a horizontal dimension to the adjustment capability to compensate for uneven subfloors
Solution Approach 2:
Laterally projecting tabs with support legs act as intermediary elements between the base section and the subfloor, providing adjustable support to level the laying box on uneven surfaces while maintaining the simple guided assembly of the cover section
3Ease of manufacture
If support legs are positioned centrally in the base, then manufacturing is simplified, but screed flow is blocked and positioning precision is reduced
Solution Approach 1:
Support legs are positioned asymmetrically at the ends of laterally projecting tabs rather than centrally in the base, creating an uneven distribution that improves positioning precision and allows screed to flow freely to all areas including between the laying box and subfloor

AI summary
The invention relates to a duct box for installation in a floor structure and for accommodating a drain assembly for the creation of a water drain embedded in a screed, in particular for a walk-in shower, comprising a base (11) to which a circumferential side wall (12) adjoins, wherein laterally projecting outwards tabs (33) provided with a through-hole (34) are arranged on the base (11), each of which accommodates a support foot (5) that is height-adjustably mounted in the respective tab (33, 83). The invention further relates to a support rail for a duct box.
