4. Cоnsider оur discussiоn of bаrriers аnd blocks to creаtive solutions. Which barrier/block is displayed in each of the examples below? Name it and explain how it is applied to this example. In Duncker's “Candle Problem,” people see a candle, a box of thumbtacks, and matches, and are asked to affix the candle to a wall so it doesn't drip wax onto the table below. Many people struggle because they fail to consider the box as a potential candle holder. At NASA, early engineers working on the Apollo missions framed the problem as “How do we make sure astronauts survive re-entry with their spacecraft intact?” This framing resulted in bulky and complex designs. A breakthrough occurred when the task was reframed as “How do we ensure astronauts survive re-entry?” It allowed considering a smaller, lighter re-entry capsule. Airbnb's early concept was rejected: When Airbnb founders pitched their idea of renting out air mattresses in their apartment, many investors dismissed it as too far from what they believed consumers expected from hospitality services. Employees often hesitate to propose bold ideas during meetings due to fear of criticism or rejection.
