For example, the convergence simulator 60 may perform a simulation on the bio-characteristics of the 3D object designed based on the location in the human body where the 3D object will be located and the component information of the material.

Since the properties of the material allocated to each area of the designed 3D object affect the properties of the designed 3D object, the material data is necessary when performing simulation on the electrical properties, physical properties, and/or bio properties of the designed 3D objects. .

The convergence simulator 60 may compare simulation results with evaluation criteria and generate a simulation report for the simulation results.

If the simulation results do not satisfy the evaluation criteria, the convergence simulator 60 may feed the simulation report back to the material determiner 30 and the 3D designer 50. Introduction The decision maker 30 and the 3D designer 50 re-run the simulation based on the feedback simulation report, and the convergence simulator 60 re-executes the result (material data, designed 3D object (3D modeling data, part data, And connection data).

At this time, 3D printing data may be generated by slicing by material.

3D printing data is output to the 3D printer 100 and can be used for the city production test through the 3D printer 100. If the result is not good in the city production test, the simulation report generated by the 3D printer 100 is the material. It can be fed back to the crystallizer 30 and the 3D designer 50. Introduction The decision maker 30 and the 3D designer 50 re-run the simulation based on the feedback simulation report, and the convergence simulator 60 re-executes the result (material data, designed 3D object (3D modeling data, part data, And connection data).

The material determiner 30, the 3D designer 50, and the convergence simulator 60 use the feedback simulation report when the simulation result is satisfied (for example, the designed 3D object has electrical properties, mechanical properties, and/or Alternatively, the simulation process described in FIGS. 3 to 5 may be repeatedly performed until a bio characteristic is satisfied.

The part to be connected to the vehicle 500 (for example, a part to be connected to a part and/or a part to be connected to a power source) and a wire for electric transmission are integrally output and formed into one wiring part 700, thereby forming a wiring part 700 ) Is connected to the tangential portion, and the wiring part 700 may have robustness.

The exterior portion 710 may be formed of a first material, the protective separation unit 720 may be formed of a second material, and the electric wire 730 may be formed of a third material. The first material may be a carbon material (or a carbon fiber material), such as a carbon material, as a light and strong material for bonding to the vehicle body frame 550. The second material may be a non-conductive material to protect the conductive wire. The third material may be a conductive material for a wiring function.

FIG. 10 is a view for explaining an example in which the wiring unit of FIG. 9 is used in an automobile.

The wiring unit 700 is divided into a conductive material and a non-conductive material so that the output of the conductor region (eg, electrical output, etc.) can be self-checked.

The wiring unit 700 may be used to self-check the output problem of electricity. The user may connect a device capable of checking the electrical output to both ends of the wiring unit 700, and check whether the wire 730 of the wiring unit 700 is defective through the electrical output check.

At this time, the device capable of checking the electrical output may measure the resistance value and/or the amount of charge output of the electric wire 730 and determine whether or not there is a short circuit.

The wiring unit 700 may be used for a function of checking the quality of self-output through internal power level measurement and a function of determining whether there is damage afterwards. Through the output quality check for the wiring part 700, it can be used for quality inspection of the vehicle 500, intermediate inspection during use, stability inspection, and the like.

11 and 12 are views for explaining another example in which the wiring unit of FIG. 9 is used in a vehicle.

The wiring unit 700 may be used to provide safety of power supply of the vehicle 500 and a brake function when electricity supply is cut off. The wiring unit 700 may be used for an automobile brake system. The brake system of the vehicle 500 may be configured by adding a brake function to a rotating wheel or a gear box in addition to a conventional brake system of a brake pedal, a brake pad, or a brake device (eg, frame lock, etc.).

The wiring unit 700 may be formed between the power supply unit of the vehicle 500 and a driving unit (eg, a driving motor, an electric motor, etc.). The sensing device (not shown) may detect the current, voltage, and/or power flowing in the wiring unit 700 formed between the power supply unit and the driving unit to detect that the electricity supply is cut off. The sensing device may also detect that the supply of electricity to the main electrical components connected to the drive is cut off.

In addition, the sensing device may include a circuit that is driven only when the reverse current. In the brake system of the vehicle 500, a device driven only for reverse current is implemented, so that a brake function driven only for reverse current can be performed. A brake safety device that is driven by a reverse current such as a short circuit, not a break, may be a device that constitutes two lines -,- and when one line becomes + during a short circuit.

When an electrical control problem such as battery discharge during driving, fire, or electrical shutdown occurs, the sensing device detects this and the brake system of the vehicle 500 may operate in response.

The brake system may operate with a forced braking function using physical or restorative properties.

The brake method using physical properties may include a method using deformation according to a current short, such as a fuse blown. When electricity is supplied to a rotating device or a frame or connection portion close to rotation, and a high current flows, it becomes a short circuit, and if it is cut like a fuse, then the broken part can be physically designed to bend in a specific direction to brake.

The brake device may be implemented with a brake pad and/or frame lock, which causes the brake pad to contact the wheel frame and/or shaft to stop rotation. The frame lock can be inserted or coupled in a gear or pin type to the rotating shaft. A temporary electrical storage or brake (regulator) for brakes in the sensing device may be used to drive the brake device by placing the device in physical contact with the wheel frame and/or the rotating shaft.

The brake method using the restoring property utilizes a shape memory alloy to apply a specific current or heat during electric driving to keep the shape free from driving problems other than brake. When electricity is cut off, application of a specific current or heat is lost. The restoration form may be a method using a form of restoration to a brake form. This may be the most suitable type in which the use of electrical properties is the safest form and the restoration of the case where no electric power is applied.

The shape memory alloy or a material or function having a restorative property equivalent to that of a rotating device or a frame or a connection portion close to the rotation is maintained when the electricity is in operation, and when the electricity is not, it is maintained in a non-operational form in the form of a brake. Can.

In addition, the brake method may be implemented by utilizing an electric fuse provided on a wheel wheel. It maintains its shape when electricity is on (not brake), but it can be implemented by using a shape memory class that restores the brake to a possible shape when electricity is not on. The wheel is also applied to the wheel wheel to add the brake properties according to the electric transmission, and it is premised on the specific application of the electric transmission, and the feature is that it is driven independently by the wheel itself, not the existing vehicle frame.
