kontaktslösning

Kontaktslösning is a Swedish term whose meaning depends on context. In everyday Swedish, it is sometimes used informally to refer to a product for cleaning, storing, and disinfecting contact lenses. The more common term for this product is kontaktlinslösning or kontaktlösning. Such solutions typically contain sterile saline or buffered salt solutions, detergents or cleaning agents, and a disinfection component. They are intended for use with contact lenses and should be used according to the manufacturer’s instructions. Do not reuse leftover solution or use it if the bottle is damaged or past its expiration date.

In engineering and physics, kontakslösning may be used to denote the solution to a contact problem, i.e., the mathematical or computational result that describes how bodies in contact deform, press on each other, and possibly slide. Contact problems involve determining contact pressure distribution, areas of contact, and the distinction between sticking and slipping under loads. The subject draws on contact mechanics, with Hertzian theory describing simple elastic contacts, and extends to plastic deformation, adhesion, and friction. Solutions are obtained analytically for simple geometries and numerically for complex interfaces using methods such as finite element analysis or boundary element methods. Applications include gears, cam followers, seals, and forming processes.

Because kontakslösning is not universally standardized in Swedish, it is advisable to specify the intended meaning when using the term.
