Workstation Redesign & Gravity Flow Integration

During my internship at Oxus America, I led a workstation redesign initiative focused on improving material presentation, reducing operator motion, and creating a more organized and efficient assembly environment. By applying Lean Manufacturing and 5S principles, I transformed the workstation layout and integrated gravity flow racks that delivered materials directly to operators while seamlessly connecting with the facility's digital Kanban replenishment system.

The existing workstation contained five large wire racks filled with miscellaneous parts, tools, and inventory. Material organization was inconsistent, visibility was limited, and operators frequently spent time searching for components needed during assembly.

In addition, operators were required to retrieve replacement material totes from staging racks located outside of the work cell. As inventory was consumed throughout the shift, operators repeatedly left their workstations to obtain replacement materials, disrupting workflow and creating unnecessary motion.

The process resulted in:

• Excessive operator movement

• Increased material handling

• Workspace clutter

• Reduced visibility of inventory levels

• Inefficient material replenishment

I was responsible for evaluating the existing workstation layout, identifying sources of waste, and designing an improved material presentation system that would increase efficiency and support continuous flow.

My responsibilities included:

• Applying 5S principles to workstation organization

• Designing gravity flow rack configurations

• Improving material presentation and accessibility

• Integrating workstation replenishment with the digital Kanban system

• Supporting implementation and operator adoption

I began by analyzing operator movement throughout the workday and evaluating how materials were being stored, replenished, and accessed during assembly operations.

Using Lean Manufacturing principles, I focused on eliminating unnecessary motion and improving point-of-use material delivery.

The redesign centered around three key objectives:

5S Workstation Organization:

Removed unnecessary inventory storage and organized materials to create a cleaner, more efficient, and more visually manageable work environment.

Point-of-Use Material Delivery:

Designed gravity flow racks that positioned inventory directly at the operator's workstation, allowing components to be accessed without leaving the assembly area.

Digital Replenishment Integration:

Integrated the workstation with the facility's QR-code Kanban system. Once a tote was consumed, the operator scanned the Kanban tag, automatically generating a replenishment request containing both the material and quantity required.

The workstation redesign produced several operational improvements:

• Eliminated repeated operator trips outside the work cell

• Reduced non-value-added motion during assembly operations

• Improved material visibility and organization

• Enhanced workstation cleanliness through 5S implementation

• Improved ergonomics by reducing carrying and reaching

• Increased replenishment responsiveness through Kanban integration

• Created a more efficient and sustainable material flow process
