Below is a CAD drawing of the hinge on the drivers side, since the door opens outwards (direction of the arrow). The black box will be welded to the chassis. I've also attached a pictures of a Hidden Hinge welded to the frame of the car as well as a dissembled hinge. The hinge is easily to install and to manufacture. It is also durable as the hinge extends out, holding the car's weight.

Methods of Joining Door Hinge to Chassis:


AdvantageDisadvantagePicture
Welding
  • Provides strong joining
  • Seamless bond
  • Can be applied to all different geometric shaped objects
  • Permanent/ Prohibits disassembly when required
  • Requires highly skilled labour to get a strong/ perfect bond

Roll Bar Clamp/ Clamping Screws

  • Allows for disassembly
  • Easy to install
  • Screws provide strength without damaging the integrity/ strength of the material
  • Possibility of adding weight to the car
  • Excessive tightness of the clamp can cause damage

Gusset and Rivets

  • Easy to manufacture, cost and time efficient
  • High resistance against vibrational loads
  • Riveting requires enough clearance when joining, compared to other methods
  • Difficult to rivet cylindrical objects

Image Modified

Adhesive

  • Bonded joints are stiffer than spot welded joints
  • Doesn't weaken the structure/ integrity of materials 
  • Used on past MS car and was not proven to be successful
  • Essentially permanent/ no disassembly
  • Can be sensitive to temperature

Three concept design (rough CAD models or drawings): each concept should include where it mounts to chassis, direction the door swings out, how it mounts to the door and rough hinge mechanism.

Bonus: Sourced parts to compliment the concepts.
