Challenge for the Modular Logistics Vehicle Project

Challenge: MLV: Refined

Brief for MLV: Refined

** NOTICE: Validation ends Sunday April 29th at 11:59pm Pacific Time. Please make sure to have you valid entries uploaded before that time or they will not get judged. **Similar to the first Design Challenge, the objective of this Challenge is to give Marines operating on base improved functionality and experience while conducting day to day logistical operations. This new vehicle will incorporate modular adjustments to improve the Marine experience and their corresponding operations. New modules could be designed and customized on-base as new needs and use cases become discovered. (NOTE: None of these use cases are in combat. Please do NOT include weapons on the design.)For this Challenge, we are asking you to take inspiration from the winners of the previous MLV Design Challenge and either expand upon your earlier MLV concepts or design something entirely new. Designs will need to incorporate new and innovative technologies, show module designs for all four use cases, and be provided in CAD. DESIGN BRIEFDesign PrinciplesWhen designing try to stick to these design principles. Take note that we have added one more.
  1. Modular - Interoperability is all that matters
.
  2. Breakable / Hackable - Design for the need, but anticipate the unexpected.
  3. Understandable - Intuitive for users of all types to use, modify and share functional builds
  4. Function over Form - Fewer format features maximizing usability over aesthetics
  5. High Capacity - Room to hold more. More people, more equipment, more functions.
  6. Future Forward - Incorporate additive manufacturing methods and materials
See the Handbook for more detailed information.Form FactorWe saw concepts with a broad range of form factors, but the ones that stood out as being both innovative in their approach, functional, effective in their modularity all used what we would consider as a segmented design. This consists of a front cab with segmented modules that loaded in the back. These segments made for easy module swapping and simple transport.DimensionsModularityWhere many of the early entries provided solutions to the given use cases. The winning solutions had easily swappable segments or compartments that could contain everything that a module would need. In your refined design, try to design the modules as self-contained units and refer to the use cases below to see exactly what needs to be transported.  Designed for RedesignSeveral of the Judges Favorite awards were chosen because of their approach to how modules were able to be modified for future expansion into new modules. The LEMV and Universal Basic Vehicle both used a rail system that could be reconfigured or even removed. The Ugly Mule had an entire mix and match approach that was very easy to build exactly the right module that you needed to match the job. USE CASESThe vehicles we are designing need to have separate and swappable modules that can support the multiple use cases on-base. The four most common cases currently in use are as follows...Personnel ModuleMarine Corps' bases are busy and expansive.  Whether to repair vehicles and aircraft, go to training, or move to a mission staging area, Marines need to move from A to B.Module must transport:
  • 6 Occupants
  • 4 Bags
Construction Module Marines build for many different construction operations. Improving infrastructures like fences or buildings; Preservation, Packaging, and Packing (P3) of supplies, ordinance and more; are some of the building tasks.Module must transport:
  • 3 Occupants
  • EU 3000 Honda generator (120V current 23.3A frequency 60Hz)
  • 6-gallon compressor (10Amp)
  • Compound saw (15Amp 120V)
  • A retractable electrical cord reel
  • Air hose reel
  • Pneumatic nail gun
  • Woodworking tools such as hammer nails and banding equipment
Mechanical Support ModuleMarines’ aircraft, vehicles, watercraft, often break during use. Marines need to move support personnel and equipment, tools, and replacement parts to the site of the break to make repairs.Module must transport:
  • 3 Occupants
  • Diesel fuel tank 50 gallon capacity with DC fuel pump,
  • A small tool box with standard tools for servicing (total weight of box 100 lb.),
  • Spill kit (30 lb.) - oil containment, spilled fuel and fluids.  Absorbent clothes.
  • A grease gun
  • A spare tire, jack, and jack stands,
  • Miscellaneous supplies such as zip ties, duct tape Etc.
Administrative ModuleEven team leaders don’t stay behind their desks in the Marine Corps. The administrative support module will serve as a moving office for Marines overseeing operations and completing Quality Assurance tasks.Module must transport:
  • 3 Occupants
  • Solar panel peak power (W) 230 Max power current (IPM) (A) 7.58
  • Two Battery’s (voltage 13.5-14.9V 30A-60A)
  • Solar charge controller (60A mppt)
  • 5000W power inverter controller
  • Computer
  • Printer
  • Label maker
  • A small fan to vent heat with all the electronics.
TEAMSWe are really encouraging people to team up. While it is not required, there are a lot of different needs that others might be able to assist with. If you start your entry early, you can invite other community members and engage in private discussion where you can still reach out to co-pilots for questions. Check the team discussion thread to find other people interested.

Requirements for MLV: Refined

Ignition Kit File Downloads

Requirements

Requirements are elements of an Entry that MUST be accounted for in a submission. If an entry does not address these details satisfactorily, the entry will be marked as invalid.

  • At least one part of the vehicle must be created by additive methods. The part must satisfy the following requirements:
    • Manufacturing by additive methods is justified (e.g, the part fails frequently; the part is mission-critical and difficult to replace in deployed environments; the part must change dimensions regularly to provide modular functionality; gross vehicle weight is reduced when this part is generatively designed, etc.)
    • Easily viewable by observers (e.g., roll cages are easily viewable, whereas suspension A-arms are not).
  • Maximum Dimensions:
    • Height: 72” (180 cm)
    • Length: 141” (360 cm)
    • Width: 64” (160 cm)
    • Max Curb Weight: 2000 lbs (910 kg)
    • Gross Vehicle Weight: 4000 lbs (1815 kg)
    • Minimum Ground Clearance: 10” (25cm)
  • Must contain 4 distinct modules that accommodate each of the four use-cases (Construction, Administration, Personnel, Mechanical Support)  and include all of the required equipment listed in the Brief.

    The modular component should be interchangeable by 2 Marines within ~15 minutes. Additional tooling to assist lifting may be used and are not required as a part of the vehicle design but a description of how modules will be changed is required.
