Solution Overview

Problem

Existing sink accessories face challenges in being securely and stably mounted on sinks with non-uniform height levels, particularly when the faucet bank and other sections of the sink rim are at different heights, and when a worktop covers parts of the sink edge, causing height offsets that complicate the connection of accessories.

Innovation Solution

A sink accessory with a coupling device that couples only to a single coupling side wall of the sink, using an inner and outer coupling element, allowing for stable positioning without requiring uniform height levels on opposite side walls or worktops, and enabling movement along the sink's longitudinal direction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a sink accessory is placed on opposite sections of a sink edge or on a rim, then the accessory can be supported, but all support surfaces must be at the same height which limits adaptability to different sink configurations

Engineering Contradiction:
Improveadaptability to different sink height configurationsVSAvoidcomplexity of requiring uniform height support surfaces
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The coupling device transitions from requiring horizontal support surfaces to coupling with vertical side walls of the basin. The inner coupling element engages with the inner side of the coupling side wall while the outer coupling element engages with the outer side, effectively moving the support from horizontal to vertical dimension, thereby accommodating various height configurations of sink edges and worktops.

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

Solution Approach 2:

The coupling device acts as an intermediary between the sink accessory and the basin, providing a standardized interface that adapts to varying sink configurations. Rather than requiring the accessory to directly contact uniform-height support surfaces, the coupling device mediates the connection by engaging with the vertical side wall at a consistent coupling height, absorbing height variations from the sink edge and worktop.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Stability of the object's composition

If a sink accessory is coupled to both the inside and outside of a coupling side wall, then stability is improved, but the device complexity increases

Engineering Contradiction:
Improvestability of sink accessory positioningVSAvoidcomplexity of coupling device structure
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The inner coupling element and outer coupling element are merged into a single integrated coupling device structure. Rather than being separate components, they are combined into one device that simultaneously engages with both the inner and outer sides of the coupling side wall, providing stable positioning while maintaining relatively simple device construction.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The coupling device is segmented into an inner coupling element and an outer coupling element, each serving a specific function. The inner coupling element engages with the inner side of the side wall while the outer coupling element engages with the outer side, allowing independent optimization of each element's design while working together to provide stable positioning.

Inventive Principle:
Principle #1Segmentation

3Ease of operation

If a sink accessory is placed on a base area of the sink bowl, then installation is simplified, but stability and functionality are reduced

Engineering Contradiction:
Improveease of accessory installationVSAvoidstability of accessory on bowl
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

Instead of placing the accessory directly on the base area, the coupling device creates a copied or replicated mounting interface on the vertical side wall. The inner and outer coupling elements replicate the support function normally provided by horizontal surfaces, but transfer it to a vertical coupling surface, maintaining ease of installation while dramatically improving stability.

Inventive Principle:
Principle #26Copying
