Contoured Countertop
This concept is a redesign of the current sink. Instead of there being a bowl-like shape, this sink is a nearly flat surface that slopes toward the drain. The nozzle of the faucet extends to be able to reach to all areas of the sink. This design enables any size dish to fit in the sink, there is no size constraint.
Rotating Plate
- Motorized Rotating Plate
This design is unique and takes inspiration from a microwave rotating plate and applies it towards another possible use. It would be rather easy to create and prototype. It would be easy to operate for the user with a remote connected that could be placed on either side of the sink. The buttons would be large and easy to press to adjust the settings with one finger so that the user does not have to put down their scrubbing brush or rag as they are washing. The surface of the plate would be large enough to clean large dishes that cannot fit in the dishwasher. Ideally, the user could press down with their scrubbing brush or rag and the spinning/ pulsating of the rotating plate would do all the work of cleaning. The entire thing would need to be waterproofed so that the electrical components are safe when using with dish washing. The materials used would also need to be able to withstand corroding against harsh chemicals such as powerful dish detergents that some users may prefer when doing dishes. The motorization and waterproofed parts may make this the more expensive alternative compared to the hand powered rotating plate.
2. Hand-Powered Rotating Plate
This design is naturally water proof since there are no electrical components. The design is simple and would be easy to manufacture. The user would need to apply their own force to make the plate spin as they scrub since there is no motor that will spin or pulsate the plate. It may not be as practical to use if scrubbing the dish does not create the rotation that is theoretically desired. It also requires more force from the user. This may not have the same appeal to the user as the motorized plate. This could be a cheaper alternative, but for the lack of features it may not be enough to draw users in to purchase it.
Double Edged Sponge and Scraper
This simple idea enables the user to precisely clean dishes. Having a sponge and scraper share a handle makes it really easy for anyone (including people with only one hand) to transition from scraping to scrubbing. The interchangeable scrapers enable the user to scrap a wide variety of dishes.
Double Sided Suction Cup Holder
Both of these design are very simple tools that achieve the problem statements of stabilizing dishes and preventing slippages while the dishes are being washed. Its main feature, suction cups, are already used today but are applied in a new and innovative manner. Since suction cups are already well developed, there is low technical risk of this product and high technical readiness.
1.
The addition of the absorbent cloth makes this design more original since this is not something seen on the market today. It also increases the practicality of the design since this device would be used in a sink that is wet, and this therefore increases the use of this product. This design would be very easy to prototype in the next couple of weeks since suction cups are readily available and it would be easy to attach a cloth to them to test out the design.
2.
The addition of the lever greatly increases the practicality and user appeal of this design. Since the user for this product is someone with use in one hand, the lever provides a quick and easy way to remove and attach this device. Without this, it could be very difficult to remove and therefore would not be desirable for the end user. Similar suction cups are already on the market so the addition of the lever does not greatly increase technical risk.
Bed of Bristles
The bed of bristles is a relatively simple design that requires the most attention to the frame and placement of the posts. The posts need to be close enough that the are able to clean both sides of a dish without being so close that large dishes wouldn’t fit. It is also important then to choose an appropriate length for the bristles.
The second update would be to replace the bristles with a towel. This concept was further developed to ensure the towel can be removed from the frame and washed. 
Removable Silicone Sink Liner
This concept addresses two of the four problem statements defined. It addresses the issue of space by fitting into a larger sink area and it addresses the problem of slippage from the grip of the silicon liner. The primary limitation of the concept is varying sink sizes.
Clamp-On Lockable Clip Gripper
This concept addresses the issue of dish stability. The clamp feature secures the gripper to the sink and the handles squeeze until the dish is properly held and then lock into place. This design is primarily intended to hold a dish in place while it is being washed, especially dishes like pots and pans. It does have limitations, however. The size, shape, and weight of a dish impact the gripper’s ability to hold them in place. It may also be complicated to secure certain types of dishes while locking them into the gripper with just one hand.
