About
It is a cell phone cover. It is a wireless charger. It is a stationary device.It is an on the go device.
We would like to help you to get rid of some of the wires and connectors that are cluttering around your desk. Ametros Solutions is introducing the first ever flexible, soft cell phone case that charges your phone wirelessly.
The technology.
Our charging system is based on inductive charging principle. It is composed of two parts: power transmitter and power receiver. Block diagram of the charging system is shown below:
We utilized Qi compliant power managing chips. Qi is an inductive power standard developed by the Wireless Power Consortium, an international organization encompassing various manufacturing industries. The transmitter optimizes the usage of power in addition to continuously monitoring efficiency of power transfer. The receiver manager is rated at 5W and features high efficiency and low power dissipation. However, the overall efficiency of any wireless charging system is defined by the coupling coefficient of the charging coils. Higher coupling coefficient results in better power transmission and lower heat dissipation. Therefore, we have used a specific material in our charging systems to increase the coupling coefficient. As a result, the coupling in our charging systems reach up to 70%. Average charging times, from 0%-100%, are 2- 2.5 hours for iPhone 5, and 2.5-3.5 hours for Galaxy SIII phones. Moreover, our charging systems will not overcharge the phone since they stop charging when the battery is fully charged.
After spending almost two years on numerous trials and setbacks, we are introducing you the first ever FLEXIBLE wireless charging system.
AMETROS Wireless Charging Units and Accessories
Wireless charging case
In our systems, electronic circuits are incorporated onto flexible materials and embedded within the case. As a result of this, our cases are slim and light that one may mistake it as a simple case designed to protect the phone. And, it actually does that just as any other cell phone case would.
As of now, we have two lines of wireless charging cases, for iPhone 5 and Samsung Galaxy III. The cases can be twisted or bent and fit seamlessly into their respective models. After a successful Kickstarter campaign, the final products that will be manufactured, including yours, are going to be softer and we expect to offer a range of colors.
Wireless charging pads
Our wireless charging pads come in two different models: stationary and on the go charging pads. Quite an effort has been put forth to make the charging pads robust and light. We believe that the goal has been achieved in the final design. Now, our charging pad supports orientation free charging, i.e. there is no required orientation in which the phone has to be placed in. It is light and has aesthetically pleasing design. The charging pads work with any cell phone equipped with our wireless charging case.
On the go charging pad will enable you to wirelessly charge the phone in the car. Our mobile charging pad will be only slightly bigger than the phone itself so that it will not obscure the view when mounted on the windshield. We have specifically designed this feature since it is our experience that sometimes using two devices, the phone and the GPS, separately is cumbersome. It is always easier to look up information on the phone, copy and paste the necessary information or simply click to get step-by-step directions than typing these into a GPS device. Plus, it is much more convenient to place or answer a call when the phone is facing you than it were in any other place in the car. On a side note, we hope this will get you a safe driver discount since you do not have to take your eyes off of the road as much as before.
The phone stays securely on the pad thanks to magnetic points so the phone does not go off sliding to the other side of the car.
Even though mobile charging pads are custom fit for either Galaxy or iPhone 5, they will work fine with the other, just not as secure.
Risks and challenges
We firmly believe that we have overcome the most of the daunting challenges. However, there is a major remaining challenge: manufacturing and logistics thereof. The manufacturing will involve three subsequent stages each achieving a distinctive goal. They are a) manufacturing electronic circuits (case and pads); b) creating respective molds which will contain the circuit; and c) manufacturing cases utilizing the mold and and assembling the pads. Amongst these, the second step involving the power receiving case, has required a lots of creative thinking since we wanted our case to be a completely enclosed system rather than a glue-and-screw down type. Also, finding a way to incorporate the bottom connector for iPhone 5 into the case in the same manner proved to be challenging. Now, we do have mold model developed. Our power receiving prototype case differs from the mold model since we do not have the mold manufactured yet.
Estimated time frames are 25 days for the steps one and two, and 15 days for the step three. Steps one and two will start a week apart from each other. Delivery of the gifts to our backers will start once the first batch is ready. These estimates were based on manufacturing 4000 units.
We intend to have our products manufactured by experienced manufacturers. After having discussions with several manufacturers, we have chosen three companies as potential manufacturers. One specializes in manufacturing of electronic components and circuits. The others specialize in aluminum, rubber, and stainless steel manufacturing and precision machining, including fabricating molds.
It is very important to have a competent quality control and assurance mechanism in place. The aforementioned manufacturers are ISO certified and their respective QCA protocol adheres to the ISO set standards. And we are certain that we will be able to ensure the smooth production and high quality of our products.
