DFE Analysis

Table: Design for Environment Study
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


Replace aluminum components with plastic, providing a net benefit for the environment.

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
