Use Solidify modifier

Question

As you can see while using Solidify some faces appeared outside the mesh. I want them to be inside as here

Here's a drawing to illustrate what I want.

In green this is what I want. In the second color red is the original and the dark-red is effect of Solidify. I marked also with blue and green from which faces Solidify created others.

What I want to do is clamp these walls in mesh, so they cant go outside the mesh. In this case it's deleting those 2 triangles on the right. Can somebody share with me their solution?

If it isn't clear I'm soldifying inside mesh, not outside.

Have you checked for flipped normals? – Blunder Sep 22 '21 at 17:35 — Blunder, Sep 22 '21 at 17:35

You can use the Complex mode of the Solidify modifier which specifically states "This is a solidify algorithm which can handle every geometric situation to guarantee a manifold output geometry." The simple mode is just adding a specified thickness to all surfaces, regardless of whether it then protrudes out another face.
