Solution Overview

Problem

Current shower and sink designs with flat surfaces and interconnected channels for drainage often require multiple components and lack a mechanism to prevent large objects from clogging the drain, leading to inefficiencies and increased production costs.

Innovation Solution

A flat surface made from a single volume of material, such as stone or concrete, featuring radially connected channels that act as a grate to prevent clogging, with deeper channels near the drain for enhanced water flow and partial grooves to prevent spillage, allowing water to drain into a single integrated drain system.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If multiple components are used to create flat surfaces with drainage channels, then the drainage function can be achieved, but the production cost increases and manufacturing complexity increases

Engineering Contradiction:
Improveproduction costVSAvoidnumber of components
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent combines multiple separate components (flat surface, drainage channels, and grate function) into a single integrated component. The flat surface is made as one piece with channels formed directly within it, eliminating the need for separate drainage assemblies and reducing production costs while maintaining the drainage function.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The flat surface component performs multiple functions simultaneously: it provides the draining function through integrated channels, acts as a structural support surface, and serves as a grate to prevent large objects from entering the drain. This multi-functionality reduces the total number of components needed.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If traditional drainage systems are used without integrated grate protection, then water drainage is achieved, but large objects can enter and clog the drain

Engineering Contradiction:
Improvedrain clogging preventionVSAvoiddrainage system structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The grate function is merged with the flat surface and drainage channel structure. The channels themselves are designed to act as the grate, with their walls preventing large objects from entering while allowing water to pass through. This integration maintains reliability by preventing clogs without adding separate grate components.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The drainage channels serve dual purposes: they guide water flow toward the drain and simultaneously act as a physical barrier (grate) to prevent large objects from entering. This multi-functionality provides clogging prevention without increasing structural complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Reliability

If channels are made with sufficient thickness to prevent objects from entering, then clogging is prevented, but water flow capability may be reduced

Engineering Contradiction:
Improveclogging preventionVSAvoidwater drainage efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The channel walls are designed with localized thickness variations - thicker at the edges to prevent object entry and thinner in the center to allow efficient water flow. This local quality differentiation maintains both clogging prevention and drainage efficiency without compromise.

Inventive Principle:
Principle #3Local quality

AI summary

The invention relates to a flat surface for sinks and shower pans with drainage by means of channels, which, as a single component, has a flat upper surface (1) in which interconnected radial and peripheral channels (2) are made, which guide the water to a drain (3) arranged in the lower part thereof. Partial grooves (4) run between the channels (2), said grooves having a recess to prevent the water from spilling over. The upper flat surface (1) is arranged over a concave water collection tray (5) which leads into the drain (3).
