Solution Overview

Problem

Existing drain devices for damp rooms, such as showers, are cumbersome to assemble due to their design, which hinders space efficiency and storage.

Innovation Solution

A drainage device where the channel-shaped drain body is integrated within a plate-shaped part, allowing for easy stacking and connection methods like gluing, screwing, welding, clipping, or latching, ensuring the unit can be stored space-efficiently and assembled with a flush surface for tiles or as a shower surface.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the channel-shaped drain body protrudes downwards beyond the plate-shaped part, then the drainage function is improved, but the stackability and storage efficiency deteriorate

Engineering Contradiction:
Improvedrainage functionVSAvoidstorage efficiency
Core Design Contradiction:
ReliabilityVSVolume of moving object

Solution Approach 1:

The channel-shaped drain body is nested within the plate-shaped part, with the channel body receiving into a receiving space of the plate-shaped part. This nesting arrangement allows the drain body to function effectively while maintaining a compact overall profile that enables easy stacking and space-efficient storage.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The invention transitions from a protruding three-dimensional configuration to a flush integrated configuration where the channel-shaped drain body is recessed into the plate-shaped part. This dimensional reorganization maintains drainage functionality while eliminating the downward protrusion that hindered stackability.

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

2Ease of operation

If the drain body is preassembled with the plate-shaped part, then the assembly process is simplified, but the manufacturing complexity increases

Engineering Contradiction:
Improveassembly processVSAvoidmanufacturing complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The channel-shaped drain body and plate-shaped part are preassembled into a integrated unit before installation. This preliminary assembly simplifies the final installation process significantly, as the entire drainage assembly can be installed as a single unit, reducing on-site assembly complexity and time.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The drain body and plate-shaped part are combined into a single integrated unit through various connection methods (gluing, screwing, welding, clipping, or latching). This merging of components creates a unified assembly that is easier to handle and install while distributing the manufacturing complexity across standard fabrication processes.

Inventive Principle:
Principle #5Merging (Combining)

3Shape

If the drain body is integrated within the plate-shaped part, then the surface finish is improved, but the manufacturing precision requirements increase

Engineering Contradiction:
Improvesurface finishVSAvoidintegration precision
Core Design Contradiction:
ShapeVSManufacturing precision

Solution Approach 1:

The plate-shaped part features a localized receiving space with specific geometric characteristics (width and depth dimensions) that precisely accommodate the channel-shaped drain body. This local geometric design ensures flush integration and attractive appearance while managing precision requirements through well-defined local features rather than overall complexity.

Inventive Principle:
Principle #3Local quality
