Description

Dit octrooi is verleend ongeacht het bijgevoegde resultaat van het onderzoek naar de stand van de techniek en schriftelijke opinie. Het octrooischrift komt overeen met de oorspronkelijk ingediende stukken.
Lattice comprising multiple branches and joints connecting the branches
The invention relates to a lattice comprising multiple branches and joints connecting the branches.
Such a lattice is known and used in large-scale constructions such as bridges, but is not yet notably applied in micro scale applications as are the subject of the invention, examples of which will be provided hereinafter.
According to the state-of-the-art many applications require that an object is provided with a dedicated shape. To this end it is common that the object is tailored to the needs of the specific application, which is of course costly and time-consuming. For instance in orthopedics 3-D printing has been used to provide patient specific implants (PSIs) to provide the implants with the desired shape matching the patient's needs. Despite their advantages, the clinical applications of PSIs have been limited so far partially because they are usually labour-intensive, time-consuming, and expensive. That is due to the patient-specific nature of the design process, which requires many steps including image acquisition and processing, image-guided implant design, evaluation of (alternative) patient-specific design(s) in consultation with the surgeon, and a dedicated production process.
The high costs, which often are not reimbursed by health insurance companies, are not the only problem; in some cases, (e.g. traumas), it is not possible to wait several weeks to have the implant available. Moreover, medical images do not necessarily yield sufficiently accurate dimensions for the design of the PSIs. Even mildly inaccurate PSI geometries may cause problems during surgery and result in sub-optimal implantations and accelerated wear and tear.
Also in other areas, such as robotic applications, the conventional design process is cumbersome and costly. Robotic grips for organic shapes are currently constructed out of several pistons to match the shape it should lift.
It is therefore an object of the invention to avoid the conventional design method and dedicated construction and shaping of objects, and to avoid the high cost and large amount of time associated with the conventional design procedure .
Accordingly the invention proposes an entirely new approach that is based on a lattice comprising multiple branches and joints connecting the branches, and which is provided with the features of one or more of the appended claims.
First and foremost the lattice of the invention is formable into a desired shape and exhibits at least two positions, a first position wherein the joints enable that an outer circumference of the lattice conforms and is moved to the desired shape, and a second position wherein the lattice is locked into said desired shape. The invention enables that the lattice can simply be attuned to the desired shape which is required for the intended application, whereafter this shape can be frozen by the mentioned locking into the desired shape.
Considering the microscale applications in which the lattice of the invention is to be used, it is preferable that the joints are non-assembly joints that are manufactured with an additive manufacturing technique or 3-D printing.
Suitably the joints are selected from the group comprising a kinematic type and a compliant type. The kinematic type joints are for instance selected from the group comprising a hinge and a ball and socket joint, whereas the compliant type joints are operative by deformation of constituent elements of the joints.
The locking of the lattice in the second position to freeze the desired shape can be done with alternative means.
One option is that the lattice is lockable into the second position with external means. Another option is that the lattice comprises a locking mechanism for locking the lattice into the second position.
The locking mechanism is suitably embodied in one or more of the joints and selected from the group comprising an actuator, an air-canal in the lattice that can be pressurized for locking said one or more joints, and a pre-stressed element acting as locking switch upon exposure to one of mechanical vibrations or magnetic fields. The actuator can for instance comprise a network of fixed stops.
The lattice of the invention is preferably used for implant fixation in orthopedics or as a grip that can be shaped for use in a robotic application.
The invention will hereinafter be further elucidated with reference to the drawing of an exemplary embodiment of an apparatus according to the invention that is not limiting as to the appended claims.
In the drawing:
-figures 1-10 shows various embodiments of a lattice according to the invention.
Whenever in the figures the same reference numerals are applied, these numerals refer to the same parts.
Figure 1 shows two examples of lattice 1 configurations comprising multiple branches 2 and in plane revolute joints 3 connecting the branches 2. In the top part of this figure 1 the joints 3 are located at the crossing 4 of the branches 2, and in the bottom part of this figure 1 the branches 2 join at the crossing 4.
Figure 2 shows two other examples of lattice 1 configurations. In the top part on the left of figure 2 a 2D and on the right a 3D configuration of a lattice 1 is shown comprising compliant joints 3, wherein the branches 2 join at the crossings 4. At the bottom of figure 2 a lattice 1 is shown with kinematic joints 3 at the crossings 4.
Figure 3 shows on in figure 3A a lattice 1 with multiple branches 2 and in plane revolute joints 3 connecting the branches 2. Further the figure shows in figures 3 B - E how this lattice 1 can conform to four different shapes.
Figures 4A - 4D show four examples of non-assembly kinematic joint configurations. Figure 4A shows in plane revolute joints 3. Figure 4B shows joints 3 enabling an out of plane revolution. Figure 4C shows chain mail joints 3. Figure 4D shows sphereoid joints 3.
Figures 5A - 5C show three examples of non-assembly compliant joint configurations. Figure 5A shows S-joints. Figure 5B shows chicane joints. Figure 5C shows double u-notch joints. Each of these joints can be tailored to a desired stiffness and deformation behaviour.
In figure 6 an example is shown of how a lattice can be locked when it is brought into a desired shape. Figure 6A shows that the lattice is provided with air canals 5. In figure 6B the lattice is brought into a desired shape and the air canals 5 are pressurized which forces the lattice on to maintain its shape conforming to the inner boundaries 6 of the outer object 7.
Figure 7A - 7C show an example of a lattice 1 provided with a kinematic locking mechanism. At the right hand side of the figures detailed views are provided. In figure 7A the locking mechanism 5 is shown which comprises two out of plane revolute joints 5' connecting to the components of an in plane revolute joint S'’'. In this position the in plane revolute joint 5'' can move freely. In figure 7B the lattice 1 conforms to a desired shape and the out of plane joints 5' of the locking mechanism 5 are aligned. Subsequently it is shown that in figure 7C locking is accomplished by rotating the in plane revolute joint 5'' over 90° which locks the lattice 1 in the shape it has reached.
Figures 8A - 8C shows three examples of lattices 1 wherein the locking mechanism is embodied as a compliant mechanism which are shown in a detail view at the right hand side of the respective figures. Locking is accomplished by first compressing the lattice 1 which deforms the compliant members 5' , 5' ' , 5' ' ' of the lattice 1 until the lattice 1 has reached its desired shape. Subsequently the lattice 1 is released which allows the compliant members 5' , 5'', 5' ' ' of the lattice 1 to spring back and provide an outward driving force pressing the lattice 1 against the boundaries of the object to the shape of which the lattice 1 conforms.
Figures 9A - 9C shows an example of a lattice 1 which is convertible from a flat shape as shown in figure 9A into a folded shape as shown in figure 9C or vice versa, with an intermediate shape shown in figure 9B. For this purpose the lattice 1 is embodied with out of plane revolute joints 3.
Figures 10A - 10C shows stacking of flat lattices 1 according to the invention. Figure 10A shows three lattices 1 which are disconnected. In figure 10B the three lattices 1 are stacked and connected to each other using spheroid joints 3.
Figure 10C shows the stacked lattices 1 of figure 10B in a perspective view. By the act of stacking also locking of the lattices 1 is accomplished.

The discussed exemplary embodiments shall therefore not be used to construe the appended claims strictly in accordance therewith.
