Description

TANGIBLE DESIGN APPARATUS FOR LINKAGE APPARATUS FOR DESIGNING LINKING APPARATUS

The technique described below relates to a tangible design device for designing a link mechanism.

In recent years, link-based mechanisms have become more important in interactive products and system design. Recently, software tools have been introduced to solve the difficulties in link-based mechanism design. Typically, Linkage and SAM are tools for designing and simulating link-based mechanisms in software. Linkage and SAM can simulate mechanisms, but they do not support testing in production.

Conventional mechanism design brings a lot of trial and error to the actual product manufacturing process, and takes a long time to produce. The technique described below is intended to provide a system for designing a link-based mechanism.

Before describing the drawings in detail, it is to be clarified that the division of constituent parts in this specification is merely a division by main functions of each constituent part. That is, two or more constituent parts to be described below may be combined into one constituent part, or one constituent part may be divided into two or more functions according to functions that are more subdivided. In addition, each of the constituent units described below may additionally perform some or all of the functions of other constituent units in addition to the main functions of the constituent units themselves, and that some of the main functions, And may be carried out in a dedicated manner.

That is, each process may occur in the same order as described, may be performed substantially concurrently, or may be performed in the opposite order.

Link-based mechanisms are a common mechanism for designing and manufacturing moving machinery. Link-based mechanisms consist of components such as links, fixed points, motors, etc., and desired movements can be achieved by appropriately arranging the components and varying the length of the links. Link-based mechanisms are often used in the design and production of moving products such as robots, kinetic art, and automata. These mechanisms are becoming more important as interactive physical products and system designs leverage active physical computing. Hereinafter, a mechanism that operates with a link-based mechanism is called a link mechanism.

The link-based mechanism has the advantage of showing various movements, but there is a problem that it is difficult to predict because the movement changes variously as the position and number of components and the length of the link are changed. For this reason, software such as Linkage, SAM, and M.Sketch (Kim et al, 2016) for link-based mechanism design and simulation are being introduced. However, there is a problem with parts in the manufacturing process after the design process, so that the structure that works well in the program actually does not work or unexpectedly collides with the shaft or joint, the movement approaches the limit, There are many cases. In addition, when producing, it is difficult to consider the placement of other components besides the link, and also to construct a frame to hold the components. In fact, when creating works using a link-based mechanism, I am going through a lot of trial and error to complete my work. Unfamiliar designers and beginners have more difficulty in designing and building link-based mechanisms, and they have a longer trial and error time.

moving Tangjub  Design Tools

Tangible design tools for prototyping motion are also being introduced. CUBEMENT (Chung et al, 2014) and Topobo (Raffle et al, 2006) are tools that can create movements by combining modules with their respective functions. It is difficult to make movements. There is a tool called LINKKI that allows you to test link-based mechanisms. You can freely test the desired movements by assembling them using links, motors, sliders, and so on. There are various tangible design tools to prototype movements. However, the conventional tangible design tools use only hardware in production and lack connection with software.

new Tangjub  Design Tools

The following describes a new tangible design tool that can more conveniently design and test the link mechanism. 1 shows an example of a configuration of a tangible design system 100 for designing a link mechanism. The tangible design system 100 includes a projector 110, a design board 120, and a control device 130.

The projector 110 is a device for projecting a certain image on the design board 120. Projector 110 projects software content for designing the linkage.

The design board 120 is a physical tool for designing the link mechanism. The design board 120 is a device in which contents of software for design are projected. At the same time, the design board 120 corresponds to a device (frame) for manufacturing a physical link mechanism for testing. The link mechanism for testing is not a formal product, but a form of temporary assembly of components for testing. The link mechanism can be designed with the user sitting or standing. Therefore, it is preferable that the design board 120 is disposed at a constant height as shown in FIG. To this end, the design board 120 may be disposed on top of the instrument 50 having a constant height. The mechanism 50 may have a structure such as a desk, a shelf, or the like.

The control device 130 provides the content to be projected through the projector 110. The control device 130 is a device capable of performing certain computation and data processing such as a PC, a notebook computer, a smart device, and a server. The control device 130 generates image data through a predetermined program, and transmits the generated image data to the projector 110.

2 is an example of a design image projected on a design board 120 and a design board. The design board 120 has a plurality of holes H with constant spacing. The plurality of holes are for fixing and arranging the test parts. The design board 120 projects an image for the link mechanism design as described above. In FIG. 2, the image projected in the design mode 120 is indicated by a dotted line. The image virtually represents the link mechanism. The link mechanism virtually constructed in Fig. 2 includes a link, a link joint, a fixed shaft, and a motor gear. The link mechanism projected into the image is called a virtual link mechanism. The virtual link mechanism corresponds to the content generated by the control device 130 through software.

The designer must therefore provide content that represents the virtual link mechanism in a certain way. First, designers can utilize software for conventional link mechanism design. 3 is an example of a process of designing a virtual link mechanism. 3 (a) is an example of designing a link mechanism by software. The designer can design the structure of the virtual link mechanism through a program for design in a computer device. Designers can design virtual link mechanisms using conventional commercial software.

The designer can design the virtual link mechanism using the control device 130. [ In this case, the control device 130 stores the design data for the virtual link mechanism. When the designer designs the virtual link mechanism using a separate computer device, the design data must be transmitted to the control device 130. [ The control device 130 may adjust the size of the virtual link mechanism in consideration of the size of the design board 120, the distance between the projector 110 and the design board 120, and the like.

Furthermore, a method of designing a virtual link mechanism directly on the design board 120 may be used. 3 (b) is an example of designing a virtual link mechanism on the design board 120 by the designer using the dedicated input device 145. [ The input device 145 transmits information to the control device 130 about the current position (coordinate) and the type of the components constituting the link mechanism in a state of being in contact with the design board 120 or being spaced apart at regular intervals.

The input device 145 may transmit or receive electric or magnetic signals to and from the design board 120 and may transmit the position of the design board 120 to the control device 130. On the other hand, the input device 145 can input the type of a component constituting the link mechanism through a physical interface such as a button. In this case, the input device 145 may transmit the position information and / or the type of the component to the control device 130 through the short-range wireless communication.

Or the tangible design system 100 may use a separate camera. The position of the input device on the design board 120 can be grasped by the camera. The input device 145 may input the type of the component through the physical interface device. In this case, the input device 145 can transmit the type of the component to the control device 130 through the short-range wireless communication. Or the camera may acquire a constant gesture of the input device 145 and deliver it to the control device 130. [ Constant gestures match the type of specific part.

Referring to FIG. 3 (b), the designer selects the position of the component and the type of the component constituting the virtual link mechanism in real time through the input device 145. The virtual link mechanism is designed as if the designer draws a drawing on the design board 120. The designer can use the input device 145 to place a specific false part, change the type of the virtual part, or remove the placed virtual part.

After designing the virtual link mechanism, the designer can test the operation of the virtual link mechanism. When the designer delivers the test command, the control device 130 generates an image representing the operation of the virtual link mechanism. The operation of the virtual link mechanism can be defined through a program prepared in advance. The control device 130 transmits an image of the operation of the virtual link mechanism to the projector 110, and the projector 110 projects the image to the design board 120. This allows the designer to test the behavior of the virtual link mechanism in real time.

Fig. 4 shows an example in which a link mechanism is constituted as an actual test part on the design board 120. Fig. 4A is an example in which test components are arranged on the design board 120 in an environment in which the virtual link mechanism is projected. 4 (b) shows an example of a test link mechanism disposed on the design board 120. [ The test part is for making a model of the link mechanism. The test part is a small part for manufacturing the model device. Test components include links, link joints, fixed shafts, motor joints, motor gears and the like. It is assumed that the link has a straight line shape and that a plurality of holes are perforated in the linear direction for the convenience of design. In some cases, the link itself may be in a form other than a straight line. A link joint is a part for connecting a plurality of links. The link joint may be a component such as a bolt, a rivet, or the like that is inserted into a hole in a link. The link connected to the link joint is capable of rotating and moving in a constant direction while connected. The fixed axis is for fixing the link itself to a certain point. Rotational motion may also be possible for a link connected to a fixed axis. The motor gear corresponds to the axis of the motor generating the rotational motion force. The motor joint corresponds to another gear that transmits the rotational motion of the motor gear. Other parts than the parts shown in Fig. 4 (b) may be used for the test part.

The present embodiment and drawings attached hereto are only a part of the technical idea included in the above-described technology, and it is easy for a person skilled in the art to easily understand the technical idea included in the description of the above- It will be appreciated that variations that may be deduced and specific embodiments are included within the scope of the foregoing description.
