Solution Overview

Problem

Current shower tray installation methods fail to create a level surface when using thin flooring materials, making it impossible to place a strainer at the same level as the flooring without visible aesthetic disruptions.

Innovation Solution

A built-in shower tray design featuring a conduit formed by mortar ramps surrounding the draining body, combined with a mold that allows for the creation of a level surface and the use of a water-proof sheet, enabling the placement of a strainer at the same level as the flooring, with a method that includes calculating the necessary height, installing the trap body, and pouring mortar to form flush ramps.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If thin flooring materials (less than 4mm) are used to provide a modern aesthetic appearance, then the visual appeal and modernity of the shower tray is improved, but the ability to create a level surface with the strainer becomes impossible

Engineering Contradiction:
Improveaesthetic appearanceVSAvoidlevel surface creation
Core Design Contradiction:
ShapeVSManufacturing precision

Solution Approach 1:

The invention introduces a vertical dimension solution by creating a recess in the shower tray bottom and using a conduit system with variable cross-section. The conduit has a larger cross-section at the tray level and tapers to a smaller cross-section at the drain level, allowing thin flooring materials to be laid level while the drain sits lower in the recess. This dimensional approach resolves the conflict between thin flooring aesthetics and level surface requirements.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The recess is pre-formed in the shower tray bottom before installing the drain and flooring materials. This preliminary action creates the necessary space accommodation, allowing the thin flooring to be installed at a higher level while the drain sits lower in the pre-prepared recess, achieving both aesthetic thin flooring and proper drain positioning.

Inventive Principle:
Principle #10Preliminary action

2Manufacturing precision

If the strainer is placed at the level of the flooring, then an even appearance across the entire shower tray is achieved, but conventional installation methods cannot accommodate thin flooring materials to achieve this level

Engineering Contradiction:
Improvestrainer levelingVSAvoidinstallation feasibility
Core Design Contradiction:
Manufacturing precisionVSEase of manufacture

Solution Approach 1:

The conduit acts as an intermediary element between the drain outlet and the flooring level. It provides a transition pathway that allows the strainer to be positioned at flooring level while connecting to the drain outlet lower in the recess. The conduit's variable cross-section design facilitates this intermediate positioning, making the installation feasible with thin flooring materials.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If conventional drain installation methods are used, then the drain can be connected to the discharge system, but the surface cannot be made level with thin flooring materials

Engineering Contradiction:
Improvedrain connectionVSAvoidsurface levelness
Core Design Contradiction:
ReliabilityVSShape

Solution Approach 1:

The drain installation is segmented into distinct functional zones: the recess area for the drain body, the conduit area for water transition, and the flooring area for level surface. This segmentation allows each component to be optimized independently - the drain connects reliably in the recess while the flooring maintains a level surface at a different elevation.

Inventive Principle:
Principle #1Segmentation
