Example answer:

During my final year engineering project, I worked on developing a wind energy generator with a team of four people. One of the members suggested that we should use a vertical axis design instead of the traditional horizontal axis design. Initially, I was skeptical as the efficiency of vertical axis turbines is generally lower. However, we decided to explore both options in-depth as a team, conducting research and brainstorming the pros and cons of both designs. Eventually, we discovered that by using innovative methods like designing custom airfoil shapes and optimizing the generator's size, we could achieve better efficiency with the vertical axis design. This method also allowed for more flexibility in placement, which was an added advantage. By embracing different perspectives, we were able to come up with a fresh solution and produce an effective final product.

Question 4

Have you ever encountered a situation where the conventional engineering solutions seemed inefficient or too costly? How did you think outside the box to meet project requirements?

Example answer:

In one of my class projects, we were tasked with designing a portable water purification system for use in disaster relief situations. The majority of standard solutions, like reverse osmosis, were far too costly and required a significant energy input. To come up with a more practical solution, I researched alternative filtration technologies and stumbled upon ceramic filters. By combining this low-cost, passive filtration method with a minimalistic design, we were able to create an effective and affordable portable water purification system. The final product required only minimal effort from the user and provided clean water at a fraction of the cost and complexity of conventional solutions.

Question 5

Example answer:

In my previous internship, we were tasked with improving an assembly line's efficiency. After researching and analyzing, I realized that a bottleneck occurred during a specific step due to manual labor's slow pace. I remembered reading about the self-organizing principles used by ant colonies and thought that this concept could be applied to our assembly line. After discussing with my team, we used computer simulations to test a decentralized control system based on the principles of ant colonies. This enabled a more fluid workflow, reduced the bottleneck, and ultimately increased the assembly line efficiency by 15%, which was well-received by our supervisors.

Question 12

Describe a time when you faced a seemingly insurmountable engineering challenge that required you to think laterally to overcome it.

Example answer:

During a college project, our team was responsible for designing a portable water filtration system to be used in remote areas. The challenge was to create an efficient yet lightweight and compact system. Most traditional materials and techniques resulted in a bulky design that was difficult to transport. Eventually, I came up with the idea of using Origami concepts for collapsible elements. By applying this approach, we successfully created a compact and easily portable design that met all the project requirements. Moreover, it allowed us to complete the project on time and receive a high evaluation grade from our professor.

Question 13

Have you ever had to challenge traditional engineering assumptions to develop a unique solution? How did you work through this process?

Example answer:

Yes, during a summer internship, I was working on a project to decrease the energy consumption of a building. Traditionally, air conditioning systems work on a steady-state basis, maintaining a constant temperature with constant energy consumption. This method, although straightforward, was not energy-efficient. I conducted research and found that our human body can adapt to slight temperature changes. Instead of maintaining a constant temperature, I hypothesized that if we adjusted the building temperature according to recent trends and external factors, we could still maintain user comfort and save energy. After testing our hypothesis using simulations and monitoring energy consumption, we saw a substantial energy reduction of about 10%, breaking traditional design assumptions.

Question 14

Tell me about an experience where multiple creative ideas were proposed for the same engineering challenge. How did you evaluate and decide on the best solution?

Example answer:

In my senior capstone project, we were designing an energy-efficient electric scooter. Two competing ideas emerged during the ideation stage: one using regenerative braking and the other focusing on aerodynamics to reduce drag. Both ideas had their merits, but we had limited time and resources for implementation. To decide between the options, we devised a scoring system that weighed various factors like cost, energy savings, implementation duration, and feasibility. This objective approach enabled us to identify the regenerative braking concept as the most suitable one, providing the most significant benefits within the project's constraints. This resulted in a successful project and appreciation from both our peers and professors.

Question 15

Describe how you learn from creative failures or unexpected outcomes during an engineering project. Can you provide an example of when this happened and how you modified your approach?

Example answer:

I believe that sometimes failures can teach us more than successes. During a project to optimize a wind turbine's efficiency, I proposed increasing blade length. While this resulted in increased power generation in simulations, actual performance tests showed the increased weight of the blades caused mechanical stress and instability. We realized our team did not account for structural limitations in the design process properly. This learning experience taught us to be more vigilant when considering material properties and structural aspects. We subsequently adjusted our design based on these lessons, utilizing strengthening techniques and weight optimization without compromising the increased energy output. Our final design achieved 8% higher efficiency than the initial design.

Question 16

Tell me about a time when you had to devise a creative solution for a problem that initially seemed unrelated to engineering. How did you connect the dots and what was the outcome?

Example answer:

In a previous project, we were developing an irrigation system for a community garden. During our site visits, we realized that the garden was much smaller than we initially thought, making it difficult to implement our original design. It seemed like a spatial problem, not strictly an engineering one. However, I remembered learning about vertical farming, which is an innovative agricultural technique that helps optimize space usage. We decided to integrate this concept into our irrigation system's design, allowing us to layer the garden units vertically, saving space, and still providing enough water to the plants. The end result was a thriving, space-efficient garden that the community was proud of.

Question 17

Can you provide an example of how you used creative communication, visualization, or explanation techniques to help others understand a complex engineering concept?

Example answer:

During a project, I was working on implementing machine learning algorithms to optimize a manufacturing process. I needed to explain the concept to my non-technical team members, so they could understand the benefits and the principles behind it. I came up with a simple metaphor by comparing the algorithm to a student learning from a teacher. As the student receives feedback, they improve their understanding and performance, similar to how a machine learning algorithm learns from data. I also used a visual diagram to show the steps involved in the learning process. This approach helped my teammates grasp the concept easily and contributed to more informed discussions regarding the project.

Question 18

Describe an instance where you faced an ethical dilemma while trying to creatively solve an engineering problem. How did you address it?

To address this issue, I decided to introduce more inspiration into our routine by organizing a series of sessions with guest speakers from different industries. These speakers shared their experiences with creative solutions and innovative approaches in their fields. I also encouraged my team to attend relevant conferences to broaden their perspectives and explore external sources of inspiration. These actions had a positive impact on my team members' motivation and creativity and led to several novel ideas implemented into our project, ultimately enhancing its outcome.
