Functional Decomposition is a technique for breaking any problem into smaller, more easily managed parts that define the "WHAT"
Functional Decomposition is a technique for breaking any problem into smaller, more easily managed parts that define the "WHAT"
This process breaks a problem into a product’s inputs and outputs. Then each part is classified as one of the following three categories:
Energy
Material
Information
While this functional decomposition process indeed breaks the problem down and helps separate designers from their pre-conceived product concepts, it’s also cumbersome and often too detached from possible solutions.

A functional decomposition diagram is a picture that engineers draw to help them understand how all of the general tasks and subtasks in a design fit together. They use tree diagrams because these are good for showing how big things can split into smaller things (just like the branches of a tree, which split into smaller twigs).
In our analysis of Mane Magic, we have employed functional decomposition to break down the product's operation and design into its essential functions and components. Mane Magic serves the overarching purpose of dispensing the hair care product like oil and serum directly to the scalp of the user in an effective, comfortable and in a cleanly manner as a set of specific objectives it intends to achieve. Our device is focused on creating a soothing hair oil/serum application process that decreases its overall messiness. Users must be able to easily access the storage reservoir as well as clean the entire device. The device must be able to be gripped in a simple manner that doesn’t cause fatigue to the user. The main functions/steps of this product are categorized as follows:
1) Refilling the reservoir with the choice of hair care product.
2) Maneuvering the device across the scalp.
3) Dispensing mechanism
Cleaning the device post usage & storing.
Each of these functions is further divided into sub-functions and components, such as filling the reservoir with choice of hair care product having sub-functions like opening and accessing the reservoir, adding the required amount of oil/serum, securing the lid of the reservoir back on and then attaching reservoir back to the device body. Similarly, the other main function involves certain sub-function that are the actions which help in completion of the main function. This approach allows us to understand the interrelationships and dependencies between these elements, emphasizing how they collaborate to deliver the product's overall functionality. We've also identified the inputs required for each function and the expected outputs, which are crucial for ensuring smooth operation. Functional decomposition provides significant benefits, as it aids in product design, troubleshooting, and maintenance by offering a clear and structured view of the product's inner workings. In conclusion, this functional decomposition is instrumental in comprehending the product comprehensively, enabling us to design, build, and maintain it effectively.
