Solution Overview

Problem

The existing methods for installing a shower with an inclined floor are cumbersome, particularly in ensuring the correct inclination and transition between the inclined shower floor and the horizontal floor, often requiring trial and error or the use of wedges and blocks.

Innovation Solution

A shower installation kit featuring elongated side members with longitudinal flanges that define the slope of the inclined shower floor relative to the horizontal floor, these flanges being connected to and flush with the elongated drain, allowing for precise positioning before grouting and eliminating the need for wedges or blocks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If traditional grouting methods are used to create an inclined shower floor, then the shower floor can achieve the required inclination, but the installation process becomes complex and difficult to execute accurately

Engineering Contradiction:
Improveinclination accuracyVSAvoidinstallation complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The side members with integrated guide flanges are installed before grouting to pre-establish the inclination reference. This preliminary positioning of the flanges allows the grout to be applied uniformly without requiring complex trial-and-error adjustments, thereby improving inclination accuracy while reducing installation complexity

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The guide flanges act as intermediary elements between the side members and the grout layer. These flanges provide a standardized reference surface that mediates the transfer of inclination geometry from the side members to the inclined shower floor, simplifying the grouting process while ensuring precise inclination

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If multiple adjustment elements like wedges and blocks are used to achieve correct inclination, then the shower floor can be properly sloped, but the installation time and complexity increase

Engineering Contradiction:
Improveinclination adjustment easeVSAvoidinstallation time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The invention extracts and eliminates the need for separate adjustment elements like wedges and blocks by integrating the inclination guidance function directly into the side members through guide flanges. This removal of unnecessary components simplifies the installation process and reduces time loss while maintaining ease of operation

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The side members with guide flanges are designed to self-establish the correct inclination geometry without requiring external adjustment tools or multiple components. The flanges automatically provide the reference surface needed for proper sloping, making the installation process more efficient and reducing time consumption

Inventive Principle:
Principle #25Self-service

3Area of stationary object

If the drain is mounted close to the shower floor edge, then the shower design is more compact, but it becomes difficult to ensure proper transition and grouting at the edges

Engineering Contradiction:
Improveshower areaVSAvoidgrouting ease
Core Design Contradiction:
Area of stationary objectVSEase of manufacture

Solution Approach 1:

The guide flanges extend from the side members toward the drain area, acting as intermediary elements that bridge the gap between the drain mounting location and the shower floor edge. These flanges provide a continuous reference surface that facilitates proper grouting and transition even when the drain is positioned compactly near the edge

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

The shower installation kit includes an elongated drain adapted to be arranged at an inclined shower floor and at least one elongated side member adapted to be arranged at right angles to the elongated drain and at a side of the inclined shower floor. Each elongated side member has a longitudinal flange adapted to define a slope of the inclined shower floor and adapted to be positioned under a floor covering of the inclined shower floor. The drain is adapted to be mounted at a distance from a subfloor structure of the inclined shower floor before installation of the inclined shower floor. The drain is provided with a front flange adapted to be positioned under the floor covering, and the longitudinal flange of the at least one side member is connected to and arranged flush with the front flange of the drain.
