TRIZ - Intermediary
An Intermediary is a temporary or nonessential, component of a product or system which can be easily removed. The intermediary lens can be applied in one of two ways:
1. Use an intermediary carrier article or intermediary process.
a. i.e. Carpenter’s nail set, used between the hammer and the nail
2. Merge on object temporarily with another (which can be easily removed)
a. i.e. Use a pot holder to carry hot dishes to the table
A consultant is an intermediary in a business environment. The consultant comes in to the company to evaluate a certain aspect of the business or solve a problem and then leaves.
Chemical processes often use this principle. In some chemical reactions, a specific, otherwise unnecessary substance is included as an intermediary. The new chemical, Chemical C’s, sole purpose is to make the main chemicals, A and B, react faster or move the process along further.
In the old days, bootleggers used salt as an intermediary to hide their goods. When the bootleggers got a tip that authorities would be coming on board the ship to look for loot, the smugglers would put salt rocks on top of the 55-gallon drums of alcohol. They’d throw the drums overboard, and the salt rocks would cause the containers to sink.
When the authorities searched the ship, the contraband was gone. After a while, the salt would dissolve and the drums would rise back to the surface. The salt rocks served as an intermediary in the bootlegging process; a temporary step to improve the end result.
Intermediaries are even making their way into the legal system. Mediators are quite popular these days in divorce court. Rather than fighting out battles in the courtroom with expensive lawyers and legal fees, couples hire a mediator to help resolve the issues before the parties actually go before a judge. Mediation is big business in today’s divorce-happy society.
