Solution Overview
Problem
Conventional sinks lack efficient water circulation for dishwashing, do not collect food waste, require manual detergent input, lack drying functionality, and have suboptimal utilization of the dishwashing space cover.
Innovation Solution
A sink with a divided washing case, a detachable dish rack, a sump assembly for water circulation, a sliding washing cover with operational and display units, and integrated drying features, including a drying fan and heater, to facilitate automatic dishwashing, waste collection, and reduced water consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a conventional sink is used for dishwashing, then the structure is simple, but water consumption is large because water circulation is impossible
Solution Approach 1:
The washing case is divided into multiple spaces including a dishwashing space, a drying space, and a sump assembly area. This segmentation allows for separate water circulation systems in the dishwashing space while maintaining simple overall structure.
Solution Approach 2:
A sump assembly is introduced as an intermediary component to collect and recirculate washing water. The sump assembly includes a sump tank, pump, and filtration system that enables water circulation without complicating the main sink structure.
2Device complexity
If a conventional sink is used, then there is no additional equipment needed, but there is no means for collecting food waste generated in the dishwashing process
Solution Approach 1:
The food waste collection function is merged with the existing drain pipe system. The drain pipe is positioned to receive food waste from the dishwashing space and transport it to the sump assembly, combining waste collection with the water circulation system.
3Device complexity
If a conventional sink is used, then the structure is simple, but there is no means for supplying detergent for dishwashing automatically
Solution Approach 1:
A detergent container is pre-installed in the sump assembly area with an automatic dispensing mechanism. The detergent is supplied automatically to the dishwashing space through nozzles, eliminating the need for manual detergent input while keeping the overall structure relatively simple.
4Device complexity
If a conventional sink is used, then there is no additional drying equipment, but means for drying the washed dishes is not separately provided
Solution Approach 1:
The washing cover is designed to serve multiple functions: it covers the dishwashing space during washing, and when opened, reveals a drying space with drying fans and heaters. This multi-functionality adds drying capability without requiring separate drying equipment.
5Device complexity
If a fixed cover is used for the dishwashing space, then the structure is simple, but the utilization of the cover is lowered
Solution Approach 1:
The washing cover is designed to be movable rather than fixed. It can slide horizontally to cover the dishwashing space during washing operations and open to reveal the drying space. This dynamic design increases cover utilization while maintaining relatively simple structure.
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 solution enables efficient water use, automatic dishwashing with waste collection, prevents bacterial growth through drying, and enhances the utility and safety of the dishwashing cover.
Implementation Method 1
a washing pump that is mounted on the sump cover and that circulates the washing water in a state where the dish rack is mounted on the dishwashing space
Implementation Method 2
a drying fan that is mounted on the rear surface of the washing case and that generates drying air
Implementation Method 3
a drying heater that is mounted on the rear surface of the washing case and that heats the drying air generated by the drying fan

AI summary
There is provided a sink including: a washing case (12) that is divided into a plurality of spaces (121, 122) including a dishwashing space; a table (11) on which the washing case is mounted; a dish rack (14) that is detachably provided in the dishwashing space and having a washing nozzle (147) rotatably installed on a bottom; a sump assembly (20) that is mounted on a bottom surface of the dishwashing space and stores washing water to be supplied to the washing nozzle in a state where the dish rack is mounted on the dishwashing space; and a washing cover (15) that slides horizontally above the dishwashing space to be inserted into the table or to cover an opened upper surface of the dishwashing space, in which the washing cover includes an operation unit for inputting operating command for dishwashing and a display unit for displaying various information.
