One project I worked on involved a hybrid propulsion system for a reconnaissance drone, balancing the need for quiet operation with extended range. The key is always a detailed analysis of the mission profile, operational environment, and performance requirements to make an informed decision.”

23. Tell us about a time you had to redesign a component due to manufacturability issues.

Redesigning a component due to manufacturability issues requires a deep understanding of both engineering principles and production processes. Engineers often face challenges where theoretical designs don’t align with practical manufacturing constraints, such as material limits, tooling capabilities, or cost efficiency. Addressing these issues showcases an engineer’s ability to bridge the gap between concept and reality, ensuring that innovative designs can be produced reliably and economically. This question probes an engineer’s problem-solving skills, flexibility, and ability to collaborate with cross-functional teams, like manufacturing and quality assurance, to deliver viable solutions.

How to Answer: Detail a specific instance where you encountered such an issue, describing the initial design problem, the manufacturability constraints identified, and the steps taken to redesign the component. Highlighting the collaborative efforts with various stakeholders and the resulting improvements can demonstrate your technical expertise and teamwork. Emphasize the outcome, such as enhanced production efficiency, cost savings, or improved performance.

Example: “We were working on a satellite project, and one of the key structural components kept failing during the manufacturing phase. The original design was too complex, leading to inconsistencies and defects in the produced parts.

After a thorough design review and consulting with the manufacturing team, I proposed simplifying the geometry to reduce the number of intricate features that were causing the issues. I used finite element analysis to ensure the new design maintained the required structural integrity and performance criteria. We also ran a few prototypes to validate the modifications. The redesign not only resolved the manufacturability problems but also reduced production time and costs. The satellite launched successfully and has been performing as expected in orbit.”
