Solution Overview

Problem

Existing sink systems often require auxiliary devices that detract from their aesthetic appearance and create clutter, and these devices accumulate grime and dirt over time.

Innovation Solution

A sink system with integrated features such as a basin and apron attachment that allows for accessories to be inserted, removed, and repositioned within a channel without uncoupling the apron from the basin, along with a basin channel for accessory support and a drain cover system with rotational positions for water flow control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If auxiliary devices are used to provide additional functionality, then the functionality is enhanced, but the aesthetic appearance deteriorates and clutter is created

Engineering Contradiction:
ImprovefunctionalityVSAvoidaesthetic appearance
Core Design Contradiction:
Adaptability or versatilityVSShape

Solution Approach 1:

The patent integrates accessory mounting functionality directly into the apron structure by forming channels within the apron body. This merging of the mounting system into the existing apron design eliminates the need for separate auxiliary devices, thereby enhancing functionality while preserving aesthetic appearance without external clutter.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The apron is designed with multi-functionality by incorporating channels that can accommodate various accessories. The same apron structure serves both its traditional protective function and acts as a mounting system for multiple potential accessories, eliminating the need for separate auxiliary mounting devices.

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

2Adaptability or versatility

If auxiliary devices are used to provide additional functionality, then the functionality is enhanced, but grime and dirt accumulate on the devices

Engineering Contradiction:
ImprovefunctionalityVSAvoidgrime accumulation
Core Design Contradiction:
Adaptability or versatilityVSObject-generated harmful factors

Solution Approach 1:

By integrating the accessory mounting channels directly into the apron structure, the patent eliminates separate auxiliary devices that would otherwise accumulate grime. The merged design means accessories are mounted on the apron itself, reducing surfaces where dirt and grime can accumulate.

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If traditional mounting methods are used, then accessories can be attached, but the apron must be uncoupled from the basin for installation

Engineering Contradiction:
Improveaccessory attachmentVSAvoidinstallation convenience
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent incorporates mounting channels directly into the apron during manufacturing, before installation. This preliminary integration of mounting functionality allows accessories to be attached after the apron is installed on the basin, eliminating the need to uncouple the apron for accessory installation.

Inventive Principle:
Principle #10Preliminary action

4Adaptability or versatility

If more accessories are added to enhance functionality, then the versatility increases, but the counter space is consumed

Engineering Contradiction:
ImprovefunctionalityVSAvoidcounter space
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The patent moves accessory mounting from the horizontal counter surface to the vertical apron surface by forming channels within the apron structure. This dimensional transition allows accessories to be mounted on the vertical face of the apron, preserving horizontal counter space while maintaining versatility.

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

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The system provides enhanced functionality and a superior aesthetic appearance by eliminating the need for external accessories, preserving counter space, and maintaining cleanliness.

Implementation Method 1

A threaded fastener is configured to be received in the aperture and the apron slot. A nut is configured to be threaded on the threaded fastener and to interface with the apron slot to cooperate with the aperture, wherein the apron is coupled to the basin as the nut is threaded on to the threaded fastener.

Methodology Applied
Scientific EffectThreaded fastening: Screw
