8)Attach hopper
9)Fill hopper with paintballs
10)Disengage power feed
11)Aim gun at target
12)Pull trigger
13)Repeat as neccessary

Specific User Considerations

• Fatigue or weak arms can't lift gun steadily
• Extreme low temperatures
• Too rapid a rate of fire
• Assembly difficult for disabled users (lost arm, or finger)
• Bad vision
• Clogged Barrel or Debris in system

Possible Areas of Improvement

• Shooting accuracy
• Shooting range and distance
• Gas efficiency
• Weight and size of marker
• Trigger pull distance
• Multiple projectile firing
• Reduction in number of components
• Ease of disassembly for cleaning and service

Design Analysis

Design for Manufacturing and Assembly

1. This is a design built from a "line" of markers, it shares many of the same main parts found in the rest of the line:

* This repeatability is very useful in cutting cost, it requires fewer production lines
** The Grip and trigger frame is used universally across many of the available models of this generation of Spyder marker
** The Main Body was used across all of the Spyder markers, the milling and the powerfeed are the only things that may change between models
** The barrel threads are universal across Spyder markers and also fit some other brands as well - allows for customization
** Most of the exterior or main parts are built for flexibility and customization - user could purchase the lowest end model and customize it into the high end model easily
