The Design Problem
identify insights and opportunities
The goal of redesigning the airsoft gun is to provide the airsoft player with an improved experience. Improvements may come in the form of a better tactile feel, an improvement to that way that the gun operates, addressing safety concerns and so forth.
Design Ideas
"Please provide sketches and descriptions of your top three to five design concepts, describing what opportunities have been identified and how they will be addressed."
Idea #1 - Silent Gun
Airsoft players who buy sniper rifles expect their gun to behave like a sniper rifle. One feature common among some sniper rifles are that they are silenced. The L96 generates enough noise such that when it is fired, opponents may be able to pick up on a sniper's location. The main source of noise for the airsoft gun is the piston. The piston head generates significant noise when it hits the end of its casing. The other source of noise for this gun is the bolt as it is being cocked. This is especially troublesome during an airsoft game where the tendency of the user is to pull the bolt hard and quickly to get off as many shots as possible at opponents. Silencing this gun should allow the user to cock and fire the gun without being detected by the sound of his gun.
Idea #2 - Ammo Counter + Scope Indicator
Our research at an airsoft game showed one major problem with airsoft guns is that it is difficult to determine when a gun is low on ammo. One way to solve this problem is to digitally count the remaining BBs in a magazine and display that number on an electronic counter. We believe the ideal location for this counter would be behind the bolt so that the user may glance down at the counter while he is cocking the bolt. The user, however, might not always check the ammo counter before trying to shoot the gun. For that reason a red LED will be visible in the gun scope. The LED would turn on as a "NO AMMO warning" to the user, otherwise it would remain off. Although the idea is to use the LED as a "NO AMMO warning", other possible uses for the LED have been proposed such as using it to indicate whether or not the bolt is cocked or to indicate whether or not the safety is on.
Idea #3 - Custom Body
The L96 is an unwieldy gun. This can be improved on with a custom body that will reduce the gun's long 45" length and heavy 14 lb body. The length can be reduced by designing a retractable, foldable, or sliding stock. The weight can be reduced by taking out the metal weights that are in the gun. Another inclusion to a custom body that would improve the user friendliness of the gun is a built-in bi-pod.
Idea #4 - Spring-Electric Gearbox Hybrid
There are three kinds of airsoft guns: spring, electric gearbox, and gas guns. The L96 is a spring airsoft gun which means the user has to cock the gun each time he wants to fire it. While this works fine for targets at long distances, it is a tremendous disadvantage for airsoft players in a close quarters combat situation. Airsoft guns with electric gearboxes dominate in those situations because their gearboxes allows a high rate of fire (~10 BBs/sec). The L96 could be outfitted with an electric gearbox to serve as a secondary mode of fire made especially to help out in close quarters combat.
