"Portable Charging Apparatus" in Patent Application Approval Process

September 11, 2014



By a News Reporter-Staff News Editor at Politics & Government Week -- A patent application by the inventors Tadd, Oliver (Harlow, GB); Kendrick, Robert (Sutton-in-Ashfield, GB), filed on April 23, 2012, was made available online on August 28, 2014, according to news reporting originating from Washington, D.C., by VerticalNews correspondents.

This patent application is assigned to Sandal Plc.

The following quote was obtained by the news editors from the background information supplied by the inventors: "Modern mobile telephones, personal digital assistants (PDAs) and other handheld electronic devices typically consume a large amount of power, particularly given the recent trend towards as increased display screen size, 'always on' wireless connectivity and handheld electronic devices increasingly being used as portable media players. Many devices of this type are also preferably as compact as possible and so necessarily require compact means of storing power. The result is that many modern handheld electronic devices incorporate a relatively small battery, which is only capable of providing power for a relatively short time. Such devices therefore suffer from a short battery life and consequently require frequent charging.

"Typically a handheld electronic device is recharged by connecting it to a mains electrical supply directly via a power cable, or by placing it in a cradle which is in turn connected to a mains electrical supply. This type of charging is fundamentally incompatible with the mobile nature of these devices and further is subject to the availability of a mains electrical outlet.

"Attempts have been made to address this problem of mobility by providing a portable power source that can be connected to a handheld electronic device in order to recharge it in situ. One such example is US Patent Application No. 2010 0,754,527 which discloses a portable cradle unit that features a battery and a built-in solar charger for use with a mobile telephone. The user places their mobile telephone inside the frame of cradle to allow it to connect to a battery contained therein in order to allow it to charge.

"A problem with existing portable charging units of the type disclosed in US 2010 0,754,527 is that the charging cradle must necessarily be designed to accommodate the particular handheld electronic device for which it is designed to charge. The cradle is therefore limited for use only with this particular device, or in some cases family of devices. This lack of flexibility is not desirable given the many different types of handheld electronic device that exist today, each having a unique configuration of socket positions, control buttons, speakers, camera lenses and the like.

"A further problem with portable charging units in general is that they can be cumbersome and hence discourage or even prevent the user from enjoying the full functionality of their device whilst it is being charged. In the case of a mobile telephone, for example, a portable cradle charger may prevent the user from gaining accessing to the microphone and/or speaker in order to make a telephone call whilst the device is charging. In another example, the position of the charging unit could prevent the user from inserting headphones into their device, precluding them from listening to music whilst the device is charging."

In addition to the background information obtained for this patent application, VerticalNews journalists also obtained the inventors' summary information for this patent application: "According to a first aspect, the present invention provides a portable charging apparatus for a handheld electronic device having a housing including an internal battery, the portable charging device comprising: a power supply; an electrically conductive means for providing power from the power supply, the electrically conductive means comprising a wire having a plug at a distal end for detachably connecting to a charging port of a handheld electronic device, wherein one or more channels are formed in the power supply and are arranged to accommodate the wire whilst the device is in use; and securing means for detachably securing the portable charging apparatus to the housing of the handheld electronic device, whereby in use the portable charging apparatus is secured to an outer surface of the housing of the handheld electronic device.

"From a second aspect, the present invention provides a portable charging apparatus for a handheld electronic device, comprising: a power supply means having a power supply and at least one interface port providing an electrical connection to the power supply; securing means for detachably securing the power supply means to a handheld electronic device; and a connector unit comprising an electrically conductive member having a first connector for detachably electrically connecting to the handheld electronic device and a second connector for electrically connecting to the interface port of the power supply means; wherein the second connector is mountable on the power supply means such that the connector unit is movable relative to the power supply means.

"From a third aspect, the present invention provides a power supply for use in recharging a battery of a handheld electronic device, the power supply comprising an interface port on a major surface for receiving a connector, and means for securing the power supply to an outer surface of the handheld electronic device.

"From a fourth aspect, the present invention provides a connector unit for use with the above-defined power supply means, the connector unit having a housing comprising: an electrically conductive means contained therein; and a plug electrically connected to the electrically conductive means and extending in a first direction from the housing, the plug adapted to detachably connect to an charging port of a handheld electronic device, wherein the plug is movable within the housing in at least a second direction transverse to the first direction.

"From a fifth aspect, the present invention provides a handheld electronic device having a housing including an internal battery, the portable charging device comprising: a power supply; an electrically conductive means for providing power from the power supply, the electrically conductive means comprising a plug for detachably connecting to an charging port of a handheld electronic device; and securing means for detachably securing the power supply to the housing of the handheld electronic device, wherein the plug is movable relative to the power supply such that, in use, the plug can be moved into alignment with the charging port of the handheld electronic device before securing the power supply to the housing of the handheld electronic device.
