Description

TITLEFORCE FOCUSING DEVICEFIELD

[0002] Mechanical devices for harnessing forces, such as engines or motors, are ubiquitous in modern technology.

[0003] In general terms, an engine or motor can be described as a device or machine that harnesses or converts one or more forms of energy into mechanical energy, typically for the purpose of applying force. A range of motor technologies exist, including heat engines (e.g. combustion and non-combustion heat engines); non-thermal chemical engines (e.g. natural and synthetic molecular motors); electric motors; and physically powered motors (e.g. pneumatic and hydraulic motors).

[0004] In at least some contexts (e.g. such as transport technology) performance of engines or motors may be assessed using criteria including speed, thrust, torque, power, efficiency, and / or emission levels. Different engine or motor technologies typically have advantages and disadvantages in respect of one or more criteria.

[0005] Given the extremely widespread requirements for and applications involving controlled use of mechanical force, new approaches for harnessing or deploying mechanical force would be desirable. It could be particularly desirable if such new approaches provided one or more benefits or advantages as compared to existing approaches or technologies, such as existing motor or engine technologies.

[0184] The present invention is at least partly predicated on the realisation by the inventor that it could be possible to harness centripetal force in response to synchronised rotation of massed objects to achieve net directional force, if respective centripetal forces on the massed objects interacted during the synchronised rotation to apply net force in a single direction.

[0185] The skilled person will appreciate that ‘mass’ is an intrinsic property of an object and is a measure of the amount of matter in the object. The skilled person will further appreciate that, scientifically defined, ‘weight’ is the force exerted on a massed object by gravity. To avoid doubt, as used herein, unless the context requires otherwise, the term “weight’ will be broadly understood to encompass any object with mass.

[0186] Broadly, the inventor considers that harnessing of centripetal force can be achieved by modifying or manipulating paths of a plurality of weights in response to synchronised rotation in opposite directions, such that the respective weights pass through respective centres or axes of rotation and return to corresponding positions away from the respective centres or axes of rotation during each synchronised rotation cycle.

[0187] The inventor considers that harnessing of centripetal force as broadly conceived for this invention may be practically implemented in a variety of ways.

[0188] Without being bound by theory, the inventor considers that harnessing of centripetal force to achieve net directional force for the invention is broadly made possible, at least in part, because rotating objects do not experience centripetal at the axis of rotation. The inventor has recognised that where a rotating object can bemanipulated to pass through the centre of rotation, this results in an overall unbalancing of centripetal force on the object. This unbalancing can be harnessed to achieve net directional force.

[0189] With the preceding in mind, Figure 1 , Figure 2, and Figure 3 provide conceptual illustration of development of one approach for modifying paths of paired weights in response to synchronised rotation in opposite directions. Certain aspects and embodiments of the present invention have been achieved in accordance with this conceptual illustration.

[0190] Figure 1 shows a schematic of a device comprising a frame comprising paired rotating discs, each rotating disc comprising a centre point (C); and a weight adjacent a circumference of the disc, each weight following a path adjacent the circumference with rotation of the respective disc.

[0191] A frame of reference is provided showing forward (F), back (B), left (L), and right (R) directions relative to a plane on which the device of Figure 1 lies. As indicated by arrows, the paired discs are undergoing synchronised rotation in opposite directions.

[0192] Four exemplary positions of each weight (W1 -A, W2-A, W3-A, W4-A; and W1 -B, W2-B, W3-B, W4-B) as the discs rotate are shown. The skilled person will appreciate that, as each disc rotates, centripetal force acts on each weight towards respective centres of each disc. The skilled person will further appreciate that, with each rotation cycle of the paired discs, there is an overall balancing and / or cancellation of centripetal forces acting within the device, described in further detail as follows.

[0193] In the course of each full cycle, directional centripetal force (in the F direction) when the respective weights are at positions W1 -A and W1 -B is balanced with opposite directional force (in the B direction) when the respective weights are at positions W3-A and W3-B.

[0194] In the course of each full cycle, directional centripetal force (in the L direction) when one weight is at position W2-A is cancelled by opposite directional force (in the R direction) when the other weight is at position W2-B; and directional centripetal force (in the R direction) when one weight is at position W4-A is cancelled by opposite directional force (in the L direction) when the other weight is at position W4-B.

[0195] In the course of each full cycle, there is a combination of cancellation (in the L and R directions) and balancing (in the F and B directions) of centripetal force acting on the respective weights when the weights are in positions between W1 - A / W1 -B to W2-A / W2-B; W2-A / W2-B to W3-A / W3-B; W3-A / W3-B to W4-A / W4-B; and W4-A / W4-B to W1 -A / W1 -B.

[0196] In consideration of the above, the skilled person will understand that no net directional force in the Figure 1 device is expected during cyclical rotation of the paired discs.

[0197] Figure 2 shows a schematic of another device comprising paired rotating discs within a frame. As for the device of Figure 1 , each rotating disc comprises a weight, and the paired discs are undergoing synchronised rotation in opposite directions.

[0198] In the Figure 2 device, rather than being fitted to remain at the circumference with the rotation of the respective discs, the weights are manipulated to follow a circular path as indicated by hatched arrows between a position at the circumference of the respective disc, through the centre of the respective disc.

[0199] As for Figure 1 , four exemplary positions of each weight (W1 -A, W2-A, W3-A, W4-A; and W1 -B, W2-B, W3-B, W4-B) as the discs rotate are shown for the Figure 2 device.

[0200] The skilled person will appreciate that the centripetal force acting on each respective weight at a given position is related to the distance of the respective weight from the disc centre (C) at that position. For constant angular speed, centripetal force increases with radius, such that centripetal force acting on the weights is greatest at respective positions W1 -A and W1 -B, with centripetal force decreasing as the respective weights pass from W1 -A / W1 -B to W3-A / W3-B, and centripetal force increasing as the respective weights pass from W3-A / W3-B to W1 - A / W1 -B.

[0201] The skilled person will also appreciate that at respective positions W3- A / W3-B, the respective weights are at the respective centres of rotation of the discs, such that zero centripetal force is acting on the weights.

[0202] For the Figure 2 device, with each rotation cycle of the paired discs, there is net directional force acting within the device, described in further detail as follows.

[0203] During each cycle, maximum directional centripetal force (in the F direction) acts on the weights at respective positions W1 -A and W1 -B. Unlike for the Figure 1 device, no balancing (in the B direction) of the centripetal force acting on the weights at respective positions W1 -A and W1 -B occurs when the weights are at respective positions W3-A and W3-B. This is because positions W3-A and W3-B are at the centre of the respective discs with no centripetal force acting thereon.

[0204] Similarly as for the Figure 1 device, for the Figure 2 device, directional centripetal force (in the L direction) when one weight is at position W2-A is cancelled by opposite directional force (in the R direction) when the other weight is at position W2-B; and directional centripetal force (in the R direction) when one weight is at W4- A is cancelled by opposite directional force (in the L direction) when the other weight is at W4-B.

[0205] For the Figure 2 device, there is a combination of cancellation (in the L and R directions) and partial balancing or offsetting (in the F and B directions) of centripetal force acting on the respective weights when the weights are in positions between W1 -A / W1 -B to W2-A / W2-B; W2-A / W2-B to W3-A / W3-B; W3-A / W3-B to W4- A / W4-B; and W4-A / W4-B to W1 -A / W1 -B.

[0206] In this context, it will be appreciated that the partial balancing or offsetting of centripetal force in the F and B directions for the Figure 2 device, as compared to the balancing of centripetal force in the F and B directions for the Figure 1 device, arises due to the greater magnitude of centripetal force acting on the weights in the F direction, due to the greater distance from the centre point (C) of the rotating discs, when the weights are between positions W1 -A / W1 -B and W2-A / W2-B; and W4- A / W4-B and W1 -A / W1 -B, as compared to the lesser magnitude of centripetal force acting on the weights in the B direction, due to the lesser distance from the centre point (C) of the rotating discs, when the weights are between positions W2-A / W2-B and W3-A / W3-B; and W3-A / W3-B and W4-A / W4-B.

[0207] In consideration of the above, the skilled person will understand that net directional force in the Figure 2 device, in the F direction, is expected during cyclical rotation of the paired discs.

[0208] Figure 3 shows a schematic of a device similar to the Figure 2 device, wherein guiding of the weights to follow a circular path between the position at the circumference of the respective disc, through the centre of the respective disc, isachieved using respective channels of the rotating discs together with respective guides.

[0209] Each of the rotating discs of the Figure 3 device comprises a channel extending diametrically to opposite positions at the perimeter of the disc, each weight movable in the respective channel.

[0210] The Figure 3 device further comprises paired guides for manipulating each of the weights to follow an orbital path between a position at the circumference of the respective disc through the centre of the respective disc, as the weight moves in the respective channel during rotation of the rotating disc.

[0211] Four exemplary positions of each channel (C1 -A, C2-A, C3-A, and C4-A; and C1 -B, C2-B, C3-B, and C4-B) as the discs rotate are shown for the Figure 3 device.

[0212] During operation of the Figure 3 device in a cycle commencing with the respective channels at the C1 -A / C1 -B positions: with the respective channels at the C1 -A / C1 -B positions, the respective weights are at the W1 -A / W1 -B positions; as the respective channels rotate towards the C2-A / C2-B positions, the respective weights move towards the centre of the respective discs with trajectory manipulated by the respective guides, the respective weights reaching the W2-A / W2- B positions when the respective channels reach the C2-A / C2-B positions; as the respective channels rotate from the C2-A / C2-B positions towards the C3-A / C3-B positions, the respective weights move further towards the centre of the respective discs with trajectory manipulated by the respective guides, the respective weights reaching the W3-A / W3-B positions when the respective channels reach the C3-A / C3-B positions. as the respective channels rotate from the C3-A / C3-B positions to the C4- A / C4-B positions, the respective weights move away from the centre of the respective discs with trajectory manipulated by the respective guides, the respective weights reaching the W4-A / W4-B positions when the respective channels reach the C4-A / C4-B positions; as the respective channels rotate from the C4-A / C4-B positions towards the C1 -A / C1 -B positions, the respective weights move further away from the centre of the respective discs with trajectory manipulated by the respective guides, the respectiveweights reaching the W1 -A / W1 -B positions when the respective channels reach the C1 -A / C1 -B positions.

[0213] It is to be understood that, although the paths of the weights, as illustrated and described with reference to the Figure 2 device and the Figure 3 device, are circular paths, the paths need not necessarily be circular. Various orbits passing through the centre of the rotating discs (or alternative rotating objects) may be suitable in the context of the invention.

[0214] With the preceding conceptual illustration in mind, Figures 4 to 12 show device 100, an embodiment of a device according to an aspect of the present invention.

[0215] As can be seen in Figures 4 and 5, device 100 comprises frame 200; discs 300; weights 400; guides 500; and drives 600.

[0216] Frame 200 of device 100 is a substantially rectangular frame, a three- dimensional shape of which may be defined by front 201 ; back 202; top 203; bottom 204; left side 205; and right side 206.

[0217] Frame 100 comprises casing 210; braces 220; wheels 230; and power source compartment 240.

[0218] Casing 210 of frame 200 is located centrally within frame 200. Casing 210 comprises disc cavities 21 1 ; and drive cavities 212.

[0284] Typical use of the devices (device 100, device 1000) as hereinabove detailed will now be described.

[0285] In use, the devices (device 100, device 1000) can focus force acting on weights 400 (400A, 400B) in the direction of front 201 (201 A, 201 B) of frame 200 (200A, 200B). It will be appreciated that various effects of focusing force in the direction of front 201 (201 A, 201 B) of frame 200 (200A, 200B) can be achieved by adjusting orientation of the device (device 100, device 1000) and / or proximity of the device (device 100, device 1000) to one or more other surfaces or objects etc.

[0286] By way of example, when the device (device 100, device 1000) is placed with bottom 204 (204A, 204B) of frame 200 (200A, 200B) adjacent a flat ground surface (such as on wheels 230A), activation of the device results in force applied through frame 200 (200A, 200B) to propel the device (device 100, device 1000) in a forward direction.

[0287] By way of example, when the device (device 100, device 1000) is placed with front 201 of frame 200 against a flat ground surface, activation of the device (device 100, device 1000) results in force applied through frame 200 (200A, 200B) against the ground surface.

[0288] By way of example, when the device (device 100, device 1000) is placed with back 202 (202A, 202B) of frame 200 (200A, 200B) against a flat ground surface, activation of the device (device 100, device 1000) results in force applied through frame 200 (200A, 200B) away from the ground surface.

[0289] In use, when the device (device 100, device 1000) is activated, power source 650 (650A, 650B) powers drive motors 610 (610A, 610B) of drives 600, wherein drive gears 620 (620A, 620B) of drives 600 (600A, 600B) rotate in a synchronised manner.

[0290] In use, synchronised rotation of drive gears 620 (620A, 620B) of drives 600 (600A, 600B) results in synchronised rotation of discs 300 (301 A, 302A; 301 B, 302B) in opposite directions via engagement of drive gear teeth of drive gears 620 (620A, 620B) with gear teeth 3321 (3321 A, 3321 B) of gears 330 (330A, 330B) of discs 300 (300A, 300B).

[0291] In use, as discs 301 (301 A, 301 B), 302 (302A, 302B) rotate in the opposite directions: tip parts 426 (426A, 426B) of weight catches 420 (420A, 420B) of weights 401 (401 A, 401 B), 402 (402A, 402B) slide and / or roll against weight tracks 5111 (5111 A, 5111 B) of guides 501 (501 A, 501 B), 502 (502A, 502B); and weight stems 430 (430A, 430B) of weights 401 (401 A, 401 B), 402 (402A, 402B) slide and / or roll within weight channels 320 (320A, 320B) of discs 301 (301 A, 301 B), 302 (302A, 302B).

[0292] Interaction of weights 401 (401 A, 401 B), 402 (402A, 402B) with weight tracks 5111 (5111 A, 5111 B) of guides 501 (501 A, 501 B), 502 (502A, 502B) and weight channels 320 (320A, 320B) of discs 301 (301 A, 301 B), 302 (302A, 302B) in the preceding manner results in weights 400 (400A, 400B) following orbital paths in the respective opposite directions of rotation of disc 301 (301 A, 301 B) and disc 302 (302A, 302B).

[0293] More particularly, taking a top down and frontwards frame of reference for the device (device 100, device 1000), disc 301 (301 A, 301 B) rotates in a clockwise direction and disc 302 (302A, 302B) rotates in a counterclockwise direction, wherein: weight 401 (401 A, 401 B) follows an orbital path in the clockwise direction between a position nearest to outer disc edge 313 (313A, 313B) of disc 301 (301 A, 301 B) and a position at centre 305 (305A, 305B) of disc 301 (301 A, 301 B); and weight 402 (402A, 402B) follows an orbital path in the counterclockwise direction between a position nearest to outer disc edge 313 (313A, 313B) of disc 302 (302A, 302B) and a position at centre 305 (305A, 305B) of disc 302 (302A, 302B).

[0294] It will be understood that, as discs 301 (301 A, 301 B), 302 (302A, 302B) rotate and weights 401 (401 A, 401 B), 402 (402A, 402B) follow the respective orbital paths, stems 430 (430A, 430B) of weights 401 (401 A, 401 B), 402 (402A, 402B) remain within respective weight channels 320 (320A, 320B), oscillating between ends 321 (321 A, 321 B), 322 (322A, 322B) of weight channels 320 (320A, 320B).
