DFE Analysis
| DFE Guideline | Good Aspects of Competitor Product and Ideas for Improvement |
|---|---|
| 0. New Concept Development | Remove fasteners to allow a snap-fit design.
Integrate a quiver into the crossbow itself, instead of having it as a separate part. Add a loading mechanism that does not require a very significant force input from the user. |
| 1. Select Low Impact Materials | Crossbow:
Aluminum, Fiberglass, Steel Bolt: Aluminum, Carbon Fiber Sling: Nylon, Foam
|
| 2. Reduce Material Amount | Slots in the crossbow body reduce mass
Limb is removable to reduce transport volume The "snap-fit" design would reduce material amount by removing the need for fasteners |
| 3. Eco-Manufacturing |
Camouflage coating requires an adhesive |
