VAVE Evaluation on a Medical Device: Achieving a 25% Cost Reduction

1. The Challenge

The client had a mature production device whose cost structure had drifted far beyond sustainable levels. Every subsystem — plastics, fasteners, connectors, PCB components, even simple elements like buttons and LEDs — contributed to an inflated cost of goods. The design had never been revisited with a value-engineering mindset, and any modification needed to remain compatible with existing tooling, assembly processes, and certification constraints. Without intervention, margins would continue to shrink and the device would struggle to compete in price-sensitive markets.

2. The Solution

We executed a full VAVE sweep across the entire product. Every mechanical and electronic part was analyzed for cost, function, and alternatives. Plastics were evaluated for material efficiency, wall thickness, and mold complexity; electronics were reviewed for lower-cost equivalents, consolidation opportunities, and connector simplification. Where true drop-in replacements existed, we validated and updated the BOM. Where geometry differed, we adjusted footprints or refined the PCB layout to integrate more cost-effective components. Over-specified parts and unnecessary features were removed without affecting performance or compliance.

The difficult part was understanding how small optimizations compound. A cheaper connector reduces assembly time; a simplified plastic eliminates a screw; a different LED footprint shrinks PCB area. Layered together, these targeted adjustments created meaningful savings without altering the device’s behavior or regulatory status.

3. The Results

The complete VAVE redesign reduced the device cost by 25%, achieved entirely through precise mechanical and electronic optimization — all while preserving tooling, certification, and production continuity.
