Engineer a self-contained, dynamic water tank to display the client’s new submersible tablet and smartphone, along with a removable supporting graphic. The components needed to be wired and powered continuously without relying on battery power. The tank also needed to be easily assembled and installed by store associates. Our critical challenges included functional reliability, ensuring no water leakage and condensation. A very tight timeline was also a factor.
To ensure reliability, we determined that moving the water up and down, rather than moving the product up and down, would greatly simplify the overall design. To accomplish this, a siphon tube was used in conjunction with a water pump, allowing constant water level movement in both directions. Using a
visible/upper tank and a reserve/lower tank, we were able to use a UL-approved underwater pump to continuously bring water from the lower tank to the upper tank. Once the water level reaches the top of the siphon tube, the water drains from the upper tank to the lower tank, and the process continually repeats.
To help prevent leakage, 3/8” acrylic was used to allow for additional gluing surface, along with a secondary sealing process within the lower tank.
Both fill and drain time were greatly reduced by adding large cubes within the upper tank, creating dry zones and essentially reducing the volume of water needed to fill to the required water level. In addition, drain time was reduced by using precise siphon tube dimensions, accelerating the siphon action.
To prevent condensation, we designed a functional yet aesthetic hole pattern on the lid. In addition, we added vent areas within the product carriage to allow for airflow and heat dissipation on the visible acrylic surfaces.
Tanks shipped to 21 Sony stores for the initial launch. The client was thrilled with the ease of set up. Sony is now launching the tanks into big box stores.
