Definitions
- the present disclosure relates to energy harvesting devices and, more particularly, relates to an energy harvesting device that converts multiaxial translational and rotational motion to unidirectional rotational motion.
- Wind energy is seasonal. Even during windy seasons, wind does not remain constant and varies periodically. Similar to Solar Energy, Wind Energy systems also require investment in stand-by sources to keep up with the demand when the winds slow down or drop to insignificant levels.
- Wave energy when compared to the other two, is more reliable. Over a wider time period a reasonably unceasing wave power supply can be expected. The energy variations are, however, not as significant as Solar and Wind Energy. But in shorter time intervals (in minutes and seconds) Wave Power fluctuates momentarily. This requires a wave power absorption and conversion system that can store momentary peak power and release for supplementation during momentary periods of low power.
- the Wave Power industry today stores this momentary excess energy in a battery as electrical energy or in a pressure vessel as pressure energy. The stored energy is utilized within short periods of time (minutes or seconds) and do not necessitate long term (in hours or days) storage.
- the present wave energy conversion devices either directly run an electric generator that stores electric energy in battery banks or operates a hydraulic motor that stores pressure energy in pressure vessels. The stored pressure is then released at a constant rate to run a hydraulic turbine / motor coupled to an electric generator.
- Wave Power Industry A problem faced by the Wave Power Industry is sudden strikes by higher intensity waves. During a given time period, kinetic forces associated with each wave is predominantly constant. However, it is not uncommon to observe a wave break with very less force or on the contrary one with much higher magnitude of force. This requires the Wave Energy Absorption and Conversion system to be adequately designed for waves with the higher magnitude to avoid structural failures.
- this member has to perform two functions— one to convey the heave motion to the device for absorption and conversion of the heave forces and other to hold the floating device in place by withstanding the unused forces caused by motions associated with sway, pitch, surge etc. This results in other complex forces like bending, shear, torsion etc. that this member has to withstand.
- the gear box can be scaled up or down based on the power requirement dictated by the specifications of the selected electrical generator or hydraulic motor. The size and strength of the structure will be designed simply to support the gear box.

- Spatially relative terms such as “inner,” “outer,” “beneath,” “below,” “lower,” “above,” “upper,” and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. Spatially relative terms may be intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as “below” or “beneath” other elements or features would then be oriented “above” the other elements or features. Thus, the example term “below” can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

- the Hollow Actuator Shaft SO can be attached to a floating device. Wave action will cause the floating device to move around in multiple directions.
- the gear box will unify all these motions onto a unidirectional rotating outer shaft that can actuate a hydraulic pump or an electric generator.
- the float can also be provided with vanes so that wave induced flowing water across the vanes can make the float rotate about the shaft S1 's axis which can also be absorbed by the gear box.
- the Gear Box can be fixed to the automobile and a weight suspended on the driving end of Shaft S1 .
- the movements experienced by the automobile will oscillate the pendulum and set the gear box in motion.
- the Gear Box can also be mounted on wheel axles and the driving end of Shaft S1 connected to the body of the automobile.
- the relative motion (generally absorbed by the shock absorbers) between the wheels and the body can be absorbed by the Gear Box and converted to unidirectional rotary motion.
- the gear arrangement can be used to pick up vibrations on railway tracks and convert them to unidirectional rotation.
- the gear arrangement can be mounted on the ground and the input shaft can be attached to the railway track.
- Runaway Energy Harvesting - General run away energy in the form of vibration energy during a bumpy ride of an automobile, an animal driven carriage on an uneven road, or on a rocking boat can be absorbed.
- the gear arrangement in these cases can be fixed in an inverted position on a frame on the vehicle or boat with the input shaft S1 / SO hanging vertically down. See FIGS. 21 A and 21 B.
- a weight can be attached to SO / S1 driving end. During a bumpy ride the weight will oscillate as a pendulum in all directions. These oscillations are converted to unidirectional rotation to power a generator.
