How to Use SIT Cards

S.I.T. (Systematic Inventive Thinking )

Each method fosters creativity and innovation by altering the structure of a product or process. Here’s an overview of how each method works and how to use the cards to apply them:

Subtraction

Subtraction involves removing an essential element from a product or process and seeing how it can still function. This can lead to unique, simplified solutions or even entirely new product categories.
 

How to Use Subtraction S.I.T. Cards:

  1. List up to 15 features of the product or process on the cards.
  2. Spread out the numbered SIT chips and randomly select one.
  3. The selected chip corresponds to the feature that will be subtracted.
  4. Consider how the product or process can function without this feature and explore potential innovations.

Example:

In a car, subtract the steering wheel. This could lead to innovations like autonomous driving technology or different control mechanisms like voice or gesture-based systems.

Multiplication

Multiplication involves copying a component but changing it in some way. This difference can be in size, shape, position, or function, leading to new features or improvements.

How to Use the Cards:

  1. Identify up to 15 features and write them on the cards.
  2. Place and mix the SIT chips.
  3. Choose a chip to determine which feature to multiply.
  4. Modify the duplicated feature in a unique way to explore different innovations.


Example:
 

In a smartphone, multiply the camera. One camera faces forward, the other back, but modify the new one to rotate, enabling 360-degree photography.

Attribute Dependency

Attribute Dependency changes the relationship between two features of a product, such that the change in one feature affects the other. This leads to products that are more adaptive or responsive to user needs or environmental conditions.

 

How to Use the Cards:

  1. Write up to 15 features on the cards.
  2. Spread out and select two SIT chips, one representing variable X and the other Y.
  3. The change in feature X will affect feature Y.
  4. Consider the new functionalities or enhancements this dependency introduces.

Example:

In eyeglasses, create an attribute dependency between light intensity and lens tint. As light increases, the tint darkens automatically.

Division

Division involves separating a product or its components and rearranging them to create new usability or to introduce new product capabilities.

How to Use the Cards:

  1. List features or components on the cards.
  2. Select a chip to decide which component to divide.
  3. Think about different ways to rearrange or position the component separately from the main unit.
  4. Explore how this changes the product’s functionality or user interaction.

Example:

Divide a washing machine into two units—one for washing and one for drying, allowing simultaneous use and saving time.

Task Unification

Task Unification assigns a new task to an existing feature of a product, thereby adding extra functionality without adding more components.

How to Use the Cards:

  1. Identify up to 15 features of the product.
  2. Use the SIT chips to choose one feature.
  3. Assign an additional task to this feature.
  4. Explore how combining these tasks can lead to innovative solutions.

Example:


In a printer, unify the task of printing with air purification. The printer filters air as it prints, reducing workspace pollution.

You have an idea…then…


After identifying the potential innovation, continue exploring, prototyping, or testing the idea to evaluate its practicality, feasibility, and market potential. This process encourages creative thinking and can be applied to virtually any product or process for innovative solutions.
