Creativity Innovation and Inventive Problem Solving Session 10

This video, "Creativity Innovation and Inventive Problem Solving Session 10," by Dr. Anuj Grover, focuses on function analysis and function modeling in engineering systems (3:34). It delves into defining functions, identifying system components, and understanding their interactions. Here's a breakdown of the key topics: Component and Interaction Analysis (3:10): The lecture begins by reviewing component analysis, which involves identifying system and super-system components, and interaction analysis, which maps how these components interact using a symmetric matrix (3:43-4:42). Defining a Function (4:44): A function is defined as an action performed by a component (carrier) to change or maintain a parameter of another component (object) (9:12-9:51). The video emphasizes using clear, active verbs and avoiding declarative or state-based verbs when defining functions (11:52-12:40). For example, "helmet deflects bullet" is a valid function, while "helmet protects head" is not (12:31-12:37). Guidelines for Functions (15:34): Functions should avoid negative formulations (e.g., "open door does not stop people" is incorrect) (15:37-15:42) and be as specific as possible regarding parameters and conditions (16:33-16:47). Main Function and Target (21:52): The main function of a system is its primary purpose, and the object of this main function is called the "target" (23:05-23:07). Identifying the target is crucial to avoid solving less important problems (23:47-24:04). Useful vs. Harmful Functions (26:38): Functions can be classified as useful (changing parameters in a desired direction) or harmful (worsening parameters in an undesired direction) (27:25-27:46). Performance of Useful Functions (28:49): Useful functions can be further categorized by their performance: normal, excessive, or insufficient (28:56-29:21). This helps in evaluating where improvements are needed. Ranking Functions (30:42): Functions are ranked based on their importance: Basic Functions: Useful functions acting on the target (highest rank) (30:58-31:14). Additional Functions: Useful functions acting on super-system components that are not the target (mid-rank) (31:22-31:29). Auxiliary Functions: Useful functions acting on components within the analyzed engineering system itself (lowest rank) (31:40-31:50). Creating a Function Model (42:48): The process involves: Indicating a component. Identifying all functions of that component using the interaction matrix. Determining and indicating the function ranks. Determining and indicating the performance level of the function. Repeating these steps for all components (42:52-43:55). Visual Representation (1:26:23): The video demonstrates how to visually represent function models using color-coding for harmful (red) and normally performed functions (regular lines), and dashed lines for insufficient functions (1:26:30-1:26:46). Goals and Outcome (1:28:20): The main goals of function analysis are to represent a system functionally, identify disadvantages, and rank functions for trimming (1:28:27-1:28:45). The outcome is a tabular or graphical model of the engineering system (1:28:48-1:28:57).
