Mechanical solution refers to a problem solution achieved by trial and error or by a fixed procedure based on learned rules.

In psychology, mechanical solution refers to a problem-solving method that relies on applying learned rules or procedures without necessarily understanding the underlying principles. This approach is characterized by a trial-and-error process, where the individual tries various solutions until a correct one is found. Mechanical solution is often used in situations where the problem is well-structured and can be solved through a set of predetermined steps.

Examples of mechanical solution can be seen in everyday tasks such as assembling furniture from a set of instructions, following a recipe to cook a meal, or solving a math problem using a formula. This type of problem-solving is also commonly used in computer programming and in certain types of manufacturing processes.

However, mechanical solutions have limitations when it comes to complex and open-ended problems that require creativity and flexibility in thinking. In these situations, other problem-solving strategies such as heuristic or insight-based approaches may be more effective.
