Key Problem to Solve

Derrick wanted to reduce muscle fatigue and improve operator readiness during a combat situation by developing a sling system that was ambidextrous and fit onto any chest protector-style body armor system. The system needed to carry and hold a long-barrel style firearm in a series of different positions, adjustable to the operator’s preference.

Derrick had a working prototype when he came to Kickr that he developed himself. His prototype did not have the waterproof or adjustable features of his desired design. Additionally, he wanted a simple, off-the-shelf mechanism to connect his rig to a firearm compared to his existing design. Lastly, Derrick wanted something that looked production-ready with an aim of moving to manufacturing.

Challenges

An updated version of his existing design that was adjustable, ambidextrous, waterproof, and leveraged off-the-shelf components.

1. Off-the-shelf component selection of a US-based vendor for his tension reel component.
2. Waterproofing the tension reel design while keeping the system adjustable for various operator demographics.
3. Integrating a mechanism that was easy to adjust the“rest” position of the firearm with off-the-shelf components. The mechanism had to be easy to find when in stressful situations but discrete as well (non-reflective, for example).
4. A system that was easy to move out of the way if the operator was injured and needed medical treatment in the field.
5. Mounting features that were agnostic to the type of chest-plate style body armor vest an operator used.

The Solution

An overview of the steps of the project and what we did for the client.

• Kickoff to understand client goals and the “why” of each feature request
• Brainstorming and concept of tension reel-box designs, vest mounting features, firearm attachment mechanisms, and adjustable position mechanisms.
• CAD development of custom designs and sourcing of off-the-shelf components that met client goals.
• Partial prototypes of the “rest” adjustment mechanism AKA Tool Strap& tension reel box
• Building several full prototypes and updating based on client testing feedback
• 1st iteration: Initial prototype with new reel mechanism, water sealing, and adjustable holster. All attached with screw clamp mechanisms.
• 2nd iteration: Improvements: gun clip style, barb connection to housing, tool strap magnet improvements, adjustability improvements
• 3rd iteration: Further improvements: gun clip style, barb connection to housing, tool strap magnet improvements, adjustability improvements, and water sealing.
• 4th iteration: Initial redesign of the shoulder mounts from clamp mechanisms to Velcro mechanism
• 5th iteration: Further improvement of shoulder straps for easy visibility, use, and removal. Update of adjustments of tool strap attachment. (Final Design)

Derrick has demonstrated at several tradeshows and has gotten tremendous interest from potential buyers and licenses.
