Hello, Please help me to propose any engineering programming EXCEPT SAFETY BOX PASSWORD RELATED like below. Please help me do flowchart, algorithm and c-codes. Please answer with different idea from any chegg answers

Example: alany Example (explain the problem): One of the major problems faced by safety box user is forget their preset password. As a result, sometimes, user unable to unlock their safety box and need to damage it to get belongings kept inside the safety box. Example solution propose: to replace the conventional safety box with a programmable safety box system. The system enable user to recall back their password (e.g asking several safety questions before display the user preset password). Your tasks (submission by 31/12/2020): 1. FIND any engineering related problem (e.g. please provide a clear figure to show the problem, all students must submit a DIFFERENT figure) 2. EXPLAIN the problem based on the selected figure. 3. PROPOSES a solution to solve the problem (flowchart, algorithm, c-codes)
