Power Generation Module Having a Universal Interface for Portable Communication Products

Iwona Turlik, Nadia Yala, and Daniel Gamota

BACKGROUND

Portable electronic products are typically powered by either primary or secondary batteries. The longevity of the battery is determined by the power consumption of the portable product and the battery capacity. Since the consumer continues to demand a smaller and lighter product, battery size and weight must decrease. To meet these consumer demands, alternative energy sources are being investigated in an attempt to supplement the battery and extend the use-life.

PROBLEM

The method of generating power via mechanical conversion has been widely used in the past. Presently, spring operated current generators for supplying controlled electric current to power radios and flashlights are commercially available. These products have integrated gearboxes, which with a turn of a crank will create enough energy to power the product for a given duration. Unfortunately the integration of this generator to the product dramatically increases the size and weight of the product. In order to take advantage of this technology to power portable products this paper discusses the development of a removable module having a universal interface which will enable the energy-creating module to be coupled to different products without compromising the size or the weight of the product.

SOLUTION

This disclosure discusses the development of a power generator module that has a universal interface for a variety of portable communication products that will enable the users to increase the longevity and enhance the efficiency of the batteries. Also this module will enable the users to recharge the portable product "anytime/anywhere."

The module for a phone can be comprised of the following components (Figure 1): user interface, motion transfer, generator, voltage regulator, and phone interface. The method for power

creation could be a crank, a knob, a rod, a pull cord or a combination of the aforementioned and it will enable a quick powering of the portable communications product (Figure 2).

The preferred embodiment for the module will consist of the following: 1) Mechanical clip-on mechanism hinge to connect the module to the portable product, 2) Universal interface comprised of a plurality of metal electrodes forming a path for electricity to pass from the module to the secondary battery in the product, 3) Self-contained charging system having a mechanical to electrical mechanism.

The module will increase the longevity and enhance the efficiency of the battery system. Also, the module will provide constant voltage
