Solution Overview

Problem

Existing sinks with integrated cutting boards or fixed inserts restrict usability and storage space, requiring manual adjustment and limiting the functionality of the sink.

Innovation Solution

A sink design featuring a separate, continuous insert plate that can be moved vertically and tilted using a lifting device with support wings, allowing for adjustable height and position without manual intervention, and a non-destructive attachment mechanism.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If an integrated base is formed with the tub, then the cutting board is always present, but the design becomes complex and storage space is restricted

Engineering Contradiction:
Improvemultifunctional useVSAvoidtub design complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The cutting board is separated from the tub as an independent insert plate that can be independently inserted into and removed from the tub. This segmentation allows the tub to have a simple, clean design while the cutting board provides multifunctional capabilities when needed.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The insert plate is made movable relative to the tub through a lifting device that enables vertical movement. This dynamic configuration allows the cutting board to be positioned at different heights and removed when not needed, transforming the system from static to adaptable.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If a fixed insert is provided, then the plate is always positioned at a single height, but usability is limited and manual adjustment is required

Engineering Contradiction:
Improveheight adjustmentVSAvoidposition flexibility
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The lifting device enables the insert plate to move vertically between different height positions. This dynamic positioning system eliminates the need for manual adjustment and allows the plate to be automatically positioned at optimal heights for different operations.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The lifting device is controlled by sensors and a control unit that automatically adjust the plate height based on detected operations. The system serves itself by sensing when the plate needs to be raised or lowered and executing the movement without user intervention.

Inventive Principle:
Principle #25Self-service

3Area of stationary object

If the lifting unit is designed centrally, then the accommodation space is not restricted, but the horizontal dimensions must be carefully optimized

Engineering Contradiction:
Improveaccommodation spaceVSAvoidlifting unit dimensions
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The lifting device is divided into a central lifting unit and separate support wings. The central unit maintains a compact footprint to preserve accommodation space, while the support wings extend laterally to provide stable support for the insert plate without adding to the central dimension.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The support wings extend in the horizontal plane perpendicular to the vertical lifting motion. This dimensional separation allows the lifting unit to remain compact vertically while the support structure provides stability horizontally, optimizing both space utilization and mechanical support.

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

AI summary

One aspect of the invention relates to a sink (1) with a basin (2) which has a base wall (3) and lateral walls (4, 5, 6, 7) adjoining the base wall and which has a receiving area (8) delimited by the walls (4 to 7). The sink (1) has an insert plate (10) which is separate from the basin (2) and which is inserted into the receiving area (8), and the sink (1) has a lifting device (11), by means of which the insert plate (10) can be moved relative to the basin (2), wherein the lifting device (11) has at least one lifting unit (28) and at least two support vanes (33; 33, 46, 47, 48) on which the insert plate (10) is supported, and the support vanes (33; 33, 46, 47, 48) are arranged on an upper end of the lifting unit (28) and are designed to protrude laterally beyond the dimensions of the lifting unit (28) on a horizontal plane.
