one way is to make the surface rougher and another way is to increase the force pushing the surfaces together.
Okay 2 ways for the friction to increase is speed and non lubricant
Rougher surface and more weight to the object increases friction
Friction between two surfaces can increase due to an increase in the roughness of the surfaces or an increase in the normal force pressing the surfaces together. Additionally, an increase in the surface area of contact between the surfaces can also lead to an increase in friction.
You can increase friction by increasing the roughness of a surface or by increasing the force pushing the surfaces together. You can decrease friction by using lubricants or reducing the contact area between the surfaces.

Roughening the surfaces: By increasing surface roughness, you create more contact points between the surfaces, increasing friction. Applying friction-enhancing materials: Adding substances like sandpaper, rubber pads, or adhesives to the surfaces can increase friction by creating resistance between the surfaces.
Friction can increase as the contact area between two surfaces increases, or if the surfaces are rougher or stickier. Additionally, an increase in force pressing the surfaces together can also increase friction.
1. Increase the normal reaction acting on the objects by pressing them together. 2. Increase the coarse nature of the surfaces so that the coefficient of friction is also increased.

Reduce friction or increase slope.
There are different ways through which helpful friction be increased. The easiest way is using coarser or rougher surface to increase resistance.
1)increasing the roughness of the surface 2)increasing the mass of the object
