DETAILED DESCRIPTION
In the following detailed description of exemplary embodiments of the invention, reference is made to the accompanying drawings that form a part hereof, and in which is shown by way of illustration specific exemplary embodiments in which the invention may be practiced. These embodiments are described in sufficient detail to enable those skilled in the art to practice the invention. Other embodiments may be utilized, and logical, mechanical, and other changes may be made without departing from the spirit or scope of the present invention. The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the present invention is defined only by the appended claims.
A conventional docking station has been developed, but this has not satisfied requirements regarding safety and reliability for weapon system operation. The conventional docking station demonstrated susceptibility to the minor shock and vibration, thereby causing the weapon system to shut down. In addition, the conventional docking station lacked environmental seals or accessibility to facilitate maintenance, and could not be reconfigured for alternate mission objectives. In order to simplify the operation of the weapon system, an integrated docking station (IDS) is required. The station provides the operator with a single hand held device for operating the weapon system.
The Naval Surface Warfare Center Dahlgren Division (NSWCDD) Integrated Docking Station (IDS) is an aluminum 14.5 in×10.5 in enclosure for the CF-19 Toughdock computer that enables integration of various weapons systems using gun fire control switches while maintaining target control access through the CF-19. The IDS is environmentally sealed and satisfies all military specifications (Mil-Spec), providing external access for a universal serial bus (USB), Ethernet, and power using Mil-Spec connectors.
The overall design has been ruggedized in order to prolong the operational life of the product, as has been demonstrated analytically by computational structural analysis and empirically by drop tests. Various configurations for the gun-fire control switches have been implemented in order to provide cross-program integration of this system.
FIG. 1 shows an isometric view of an upper portion 100 of the IDS. A top aft bridge 110 connects a top starboard arm 120 and a top port arm 130. Both arms 120 and 130 terminate opposite the bridge 110 at entrance lips 140 that enable alignment of the CF-19 Toughdock (shown as 310 in FIG. 3). Screwholes 145 in the lips 140 provide attachment access. Four square access portholes 150 are disposed along the top surfaces of arms: one on the starboard arm 120 and three on the port arm 130. These portholes 150 can be assigned to conditional command functions, including trigger, arming and misfire.
Round access ports 160, 165, 170 and 175 (of various sizes) are disposed along the lateral edge of the starboard arm 120. The first round porthole 160 provides for an Ethernet cable jack that connects internally to the Toughdock. The second round porthole 160 provides the USB connection for the Toughdock. The third round porthole 170 provides for a trigger access associated with the porthole 150 on the starboard arm 120. The fourth round port 175 provides an access for a power supply that recharges an internal battery of the Toughdock. A top surface 180 of the bridge 110 and the arms 120, 130 represents the upper extremity of the upper portion 100 at which the portholes 150 emerge. Near the corners of the bridge 110 are holes (not shown) from a bottom surface opposite the top surface 180.
FIG. 2 shows an isometric view of a lower portion 200 of the IDS. The portion 200 includes an aft spine 210, a starboard side 220, a port side 230 and a front spine 240 that enclose a base plate 250 on which the Toughdock can be disposed. A pair of front plates 260 extends perpendicular from the front spine 240, such that the plates 260 are vertical relative to the base plate 250 being horizontal. The plates 260 include screw holes 265 that align with their corresponding counterpart holes 145 on the upper portion 100. Additional screw holes 270 are disposed at the corners of the aft spine 210 that correspond to the counterpart holes at the corners of the aft bridge 110.
FIG. 3 shows an isometric exploded view 300 of the complete IDS. The upper and lower portions 100, 200 sandwich a CF-19 Toughdock computer 310 to be disposed on the base plate 250. At each corner of the Toughdock 310 is disposed an L-shape foot 320 corresponding to the screw holes 270 for securing the IDS portions together. Gun-fire push buttons 330 suspend downward into the enclosure from the corresponding portholes 150 on the arms 120 and 130 upon assembly. Optionally, the portholes 150 can be covered by a metal plate for configurations that do not require all four buttons 330.
An Ethernet Mighty Mouse connector 340 provides an Ethernet cable plug for the Toughdock 310 and protrudes through the porthole 160. A USB Mighty Mouse connector 350 provides a USB plug for the Toughdock 310 and protrudes through the porthole 165. A command port Might Mouse connector 360 protrudes through the porthole 170 and provides external access for the buttons 330 that operate trigger, arming and misfire commands. The connector 360 also enables the operator to connect to an external weapons system into the Toughdock 310.
FIG. 4 shows an isometric assembly view 400 of the complete IDS. The Toughdock 310 protrudes slightly above the top surface 180 of the upper portion 110 and bracketed by the plates 260 while supported by the base plate 250. The gun-fire buttons 350 protrude from their respective portholes 150 on the top surface 180. The connectors 340, 350 and 360 protrude from their respective portholes 160, 165 and 170 along the starboard arm 120.
In the early stages of developing the IDS for the CF-19 Toughdock 310, many commercial off-the-shelf (COTS) docking station designs were considered for the project. Although they provided the basic need of securing the laptop, the docks failed to include other criteria which are vital to military usage. A redesign of the IDS based on a commercial product was developed by NSWCDD. The ToughBook IDS was assigned various criteria to satisfy within its design.
In order to meet these criteria, extensive modifications were applied to previous docking models. In the initial approach, the initial dimensions and similar form of the previous model was maintained. However, the alterations incorporated improvements to facilitating access for maintenance as well as greater convenience in assembly and disassembly. A preliminary model demonstrated utility for numerous applications. With this dexterity, additional criteria were added to the design to be applied to other projects. The final design varied slightly to the preliminary model to achieve the following specifications: waterproof, mil-spec connections, cross program integration, drop test of four feet above ground, compatibility with a CF-19 ToughBook 310, as well as fire control switch integration for a gun weapons system.
The primary setback of this design was it was non-environmentally sealed, structurally weak, and poorly designed setup. The qualifications and goals applied in the design presented in this report were generated based primarily on cross project integration use. Various qualifications included waterproofing, military spec connections, survive a drop test of four feet, integration for gun fire control switches, and as mentioned previously, cross project integration.
The methodology for the design of the docking station used military specs along with a set of criteria it needed to meet. In addition, the design intended the station to be ergonomically productive in that the design of the docking station was not bulky, light weight, and easy to assemble. The criteria included the following:
(a) environmentally sealed;
(b) cross program integration;
(c) easy maintenance access;
(d) military specification connections;
(e) ruggedized; and
(f) integration for gun-fire control switches.
The finalized design for the docking station met all criteria as well as incorporated other non-demanding qualifications. On the starboard arm 120 are various mil spec connectors for various uses such as USB, Ethernet, ToughBook charger, etc. The CF-19 Toughbook 310 slides into place on the upper portion 110 and attaches via bolt holes placed on the underneath side of the lower portion 210. The CF-19 Toughbook 310 is mounted at the four extrudes supported by each L-foot 320. The connectors 340 and 350 are jam nut recaptacles and mount onto the side of the top plate. Each integrated gun-control button 330 for triggering is mounted by its own compression between the upper and lower portions 110 and 210 and through its corresponding porthole 150. The base plate 250 and the front plates 260 are secured to the upper portion 110 using 8-32 screws.
The electrical connections 340, 350, 360 and CF-19 Toughbook 310 are waterproof but the design of the docking station does allow for water to enter. In various exemplary embodiments, the IDS includes knife edges and grooves along with rubber seals in order to ensure no water seepage occurs so that the interior of the IDS remains completely waterproof. Other exemplary embodiments provide for alternate materials to comprise the frame, as well as various different connectors that can be attached to the frame composed of the upper and lower portions 110, 210.
While certain features of the embodiments of the invention have been illustrated as described herein, many modifications, substitutions, changes and equivalents will now occur to those skilled in the art. It is, therefore, to be understood that the appended claims are intended to cover all such modifications and changes as fall within the true spirit of the embodiments.
