Challenge
Components might join in the wrong orientation causing the product to no longer function.

Solution and Results
The team introduced features to prevent misalignment during assembly.

Challenge
The luer lock enlarged the part to an unacceptable width.

Solution and Results
The design for manufacturing process adjusted the design to reduce width and maintain a liquid seal.

Challenge
A lubricious additive within an elastomer left a residue that compromised a liquid seal.

Solution and Results
The Natech Engineers tested two materials to confirm capability and statistical process control.

Challenge
A snap fit failed a usability test, but the design of the hook was locked.

Solution and Results
The Natech Engineers adjusted the design of the mating component to optimize performance and reduce the economic impact.

Challenge
Four of the five component designs had already been defined in relative isolation and were already locked, but tolerances allowed for potential leakage risk during assembly.

Solution and Results
The Natech Engineers performed a tolerance stack analysis and refined the specifications to address the assembly risks.

Challenge
The mold had been designed and build without considering part shrinkage.

Solution and Results
The Natech engineers were able to employ a design of experiments to adjust the process rather than adjust the mold.
