Battery Powered Impact Wrench
Project Length
15 weeks
Problem Statement :
The Battery Powered Impact Wrench designed to enhance Ergonomics, Balance Weight, Increase Torque, and Improve Safety for Entry-Level Mechanics.
Skills Used :
Research, Sketching, Fushion360, Prototyping, Keyshot
demographic target : any level mechanics
Context | ​
Mechanics use impact wrenches to efficiently remove and install bolts and nuts, leveraging the tool's high torque output to handle tough jobs that would be challenging with manual tools. The rapid, concussive force delivered by impact wrenches allows mechanics to complete tasks quickly and with less physical strain. These tools are especially valuable in automotive work, where they streamline processes like tire changes and engine repairs.
​
They desire a battery powered impact wrench that provides them with balanced weight, stronger torque, great ergonomics, safety, and the ability to perform task at any stage.

problem statement
To Design a Battery Powered Impact Wrench to enhance Ergonomics, Balance Weight, Increase Torque, and Improve Safety for Entry-Level Mechanics.
design goals and objectives
BALANCE WEIGHT
Insuring that the tools weight is balanced will decreases the risk of injury.
INCREASE TORQUE
Achieving stronger torque will improve tighter fastenings, overall safety, and overall better performance.
INCREASE SAFETY
Improving safety will reduce the amount of accidents and enhances trust.
