Solution Overview

Problem

Conventional sink systems often require auxiliary devices that compromise aesthetics and create clutter, and these devices can accumulate grime, leading to an undesirable appearance.

Innovation Solution

A sink system with integrated features such as a basin and apron attachment channel that allows for the insertion, repositioning, and removal of accessories without detaching the apron, along with a molding process using a tool with insert jigs and adhesive to encapsulate the basin rim insert, providing enhanced functionality and aesthetics.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If auxiliary devices are used to attach accessories to the sink, then functionality is enhanced, but aesthetics are compromised and clutter is created

Engineering Contradiction:
ImprovefunctionalityVSAvoidaesthetics
Core Design Contradiction:
Adaptability or versatilityVSShape

Solution Approach 1:

The patent integrates accessory attachment channels directly into the sink basin structure, merging the function of accessory storage with the sink's aesthetic form. The attachment channels are molded as integral parts of the basin, eliminating the need for external auxiliary devices while maintaining visual cleanliness and aesthetic appeal.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The sink basin is designed with multiple attachment channels that can accommodate various accessories (soap dispensers, toothbrush holders, etc.), providing universal functionality. The same structural feature serves both aesthetic and functional purposes, allowing the sink to adapt to different accessory configurations without compromising design.

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

2Adaptability or versatility

If auxiliary devices are used for accessory attachment, then functionality is improved, but grime accumulation occurs leading to undesirable appearance

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

Solution Approach 1:

By integrating the attachment channels into the sink basin itself rather than using separate auxiliary devices, the design eliminates crevices and surfaces where grime can accumulate. The molded-in channels maintain smooth surfaces that are easier to clean and prevent the buildup associated with external attachment mechanisms.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of manufacture

If conventional molding processes are used, then manufacturing is simpler, but integrated features cannot be achieved

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidintegrated features
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The attachment channels and basin rim inserts are prepared in advance as separate components, with inserts being positioned and secured to the molding tool before the final basin material is applied. This preliminary positioning allows for precise integration of features while maintaining a streamlined manufacturing process.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The manufacturing process employs nested molding techniques where basin rim inserts are first attached to the molding tool, then the main basin material is applied over them. This nested approach allows multiple features to be integrated in sequence, achieving complex integrated features without significantly complicating the overall manufacturing process.

Inventive Principle:
Principle #7Nested doll (Nesting)

4Adaptability or versatility

If basin rim inserts are used for attachment, then integrated features are achieved, but manufacturing complexity increases

Engineering Contradiction:
Improveintegrated featuresVSAvoidmanufacturing complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Basin rim inserts are pre-positioned and secured to the molding tool before the main basin material is applied. This preliminary action simplifies the overall manufacturing process by separating the insertion step from the molding step, allowing for easier integration of multiple features without proportionally increasing manufacturing complexity.

Inventive Principle:
Principle #10Preliminary action
