A method of resolving a contradiction by changing a characteristic of a system over time, like adjusting the amount of air in an axe handle to make it lighter for handling and heavier for splitting.

A method for resolving contradictions by changing the physical properties of a system, such as making a platform both high and low using a movable component.

Using different physical properties or states of an object to overcome an inherent contradiction in design. E.g., an umbrella needs to be large enough to cover you from rain but small enough to fit in your bag. To solve this contradiction, a compact design folds the umbrella when not in use.

A method of separation that uses different points in time to overcome a contradiction. E.g., a pen uses an ink flow mechanism when writing and stops the flow when not writing.

A method of separation that uses different physical positions or levels of freedom to overcome a contradiction. E.g., the flexibility of a bicycle chain allows for movement on a micro level, while its rigidity at the macro level ensures strength.

A method of separation where different spatial arrangements or configurations are used to solve a contradiction. E.g., the tip of a pen needs to be small to create fine lines, while the ink reservoir needs to be large to hold enough ink.

A method of separation that exploits different spatial dimensions to overcome a contradiction. E.g., a three-dimensional object can be small in one dimension and expand in another.

A method of separation that focuses on the local properties or qualities of an object to overcome a contradiction. E.g., using a porous material allows ink to be absorbed and the pen to write smoothly.

A method of separation that involves a change in the material or state of an object to overcome a contradiction. E.g., using a different type of ink that dries quickly allows for faster writing.

A type of physical contradiction where a system needs to have different properties depending on its state or position.

A method for finding solutions to physical contradictions by identifying the specific area where the conflicting properties are needed.

This concept combines several Inventive Principles around physical contradiction and focuses on transforming a solution by adding extra components with contrasting properties.

A solution to a physical contradiction that involves making the system less dense or more porous.

The ability of a system to be easily modified or adapted to new situations or requirements.

The degree to which a system or a design is free from flaws or inconsistencies.

The time required to complete a certain task or process.

The ease of understanding and controlling a system's operations.

The process of making or producing something, often involving a sequence of steps or operations.

The degree to which something can be measured accurately.

The extent to which a system is automated, meaning how many tasks are performed by machines rather than humans.

The complexity of a device or system, referring to the number of components, interactions, and levels of sophistication.

A characteristic or attribute that defines a system and determines its performance.

The weight of an object while it is in motion, affecting its inertia and momentum.

The weight of an object that is at rest, impacting its stability and forces needed to move it.

The total length or distance traveled by a moving object, affecting its trajectory and displacement.

The total length or distance an object occupies while at rest, impacting its size and spatial requirements.

The area an object occupies while in motion, determining its interaction with the surroundings.

The area an object occupies while at rest, influencing its space requirements and stability.

The amount of space an object takes up while moving, affecting its volume and interaction with fluids.

Any dimension related to the cubic measure of space occupied by a stationary object or the space around it. This applies to objects at rest with no relative motion.

The velocity of an object, or the rate of any process or action. It can be relative to other objects or absolute, and can be linear, rotational, or both.

The force applied to an object, a push or pull that can change its motion, shape, or direction. This force can be applied to a moving or stationary object and can be linear or rotational.

Any interaction that aims to change an object's state, whether it's linear or rotational movement. Think of pushing, pulling, twisting, or applying a force to make something move or change its position.

A force that acts on a unit area, like pressure from a tire or stress on a bridge. This force can be either stretching (tensile) or squeezing (compressive).

The shape or outline of an object, both internally and externally. It's vital for how well something works and how easy it is to use.

The strength and integrity of a system's components. It describes how well a system holds together and resists breaking down. Think of it like a chain - the weakest link determines the overall strength.

The ability of an object to resist changes under force. Think of how a strong rope can hold heavy weight.

The time it takes an object or system to perform an action, from a few milliseconds to years. It's not about how long something lasts but how long it takes to do its job.

The time taken by an object or system to perform an action while at rest. This could be anything from milliseconds to years, but it's crucial to understand how long it takes for a stationary object to complete its function.

The measure of an object's heat, including factors like how much heat it can hold (heat capacity), how well it conducts heat (conductivity), and how it radiates or absorbs heat.

The amount of light that hits a surface, which influences how bright and colorful something appears. This applies to both sources of light, like lamps, and things that reflect light, like flowers.

The measure of an object's ability to do work while in motion. Think of the energy a car uses to move or a runner uses to sprint.

The measure of an object's ability to do work while it's at rest. This refers to the stored energy within an object.

The rate at which work is done. It describes how fast energy is being used to perform a task.

The rate at which energy is used or outputted. It's also known as wattage, current, horsepower, etc.

A measure of energy loss that does not contribute to useful work. This can be due to friction, dissipation, interference, etc.

The measure of loss of materials, substances, or subsystems. It can be partial or complete, permanent or temporary.

The measure of loss or waste of information associated with any of the five senses. It can be partial or complete, permanent or temporary.

The measure of time inefficiencies like waiting periods or slack time. It can be partial or complete, permanent or temporary.

The measure of the amount, quantity, or number of a system's materials, substances, parts, or fields.Substance is anything physical or temporal.

The ability of a system to operate in multiple ways or adapt to different situations.

The difficulty of taking measurements on a system or object. This might involve complex procedures, expensive equipment, or limited access.

The rate at which a system performs useful functions or operations. This can be measured in terms of output per unit time or cost per unit output.

How close a measurement is to the true value of a property.

The degree to which repeated measurements of the same property are consistent with each other.

The extent to which the actual characteristics of a system or object match the specified or required characteristics. It's essentially how closely the system works as intended.

Any factor or phenomenon that has a harmful effect on a system or object. It can be anything from contamination to weather damage.

An inefficiency or emission generated within or around a system that causes a negative impact. It can be pollutants, waste products, or emissions.

The ease with which an object or system can be manufactured, fabricated, and assembled. It considers factors like design, tooling, and process complexity.

The ease with which a system or object can be repaired, maintained, or restored to its original functionality. It considers factors like accessibility, modularity, replaceable parts, and repair time.

The extent to which a system or object can adapt to changes in its environment or operating conditions. It considers its flexibility, versatility, and ability to respond to new requirements.
