Wales will be without lock Bradley Davies for the remainder of the RBS 6 Nations after he was handed a seven-week ban in the wake of the tip tackle that saw him sin-binned in Sunday's 23-21 success over Ireland in Dublin, while captain Sam Warburton saw red for a similar tackle in the World Cup semi-final defeat to France.
Statistics show that Wales are the worst of all the Six Nations sides when it comes to conceding points while a man down, and they have paid dearly in some instances, such as the 17 points they conceded with Alun Wyn Jones in the bin during the 2010 loss to England at Twickenham.
Speaking ahead of this Sunday's Millennium Stadium meeting with Scotland, Gatland said he has asked his squad to come up with a deterrent for those that give away needless yellow cards, having not been too happy with his own proposal.
He said: "I have asked the players to come back with a suggestion on what we need to do in the future as a deterrent for yellow cards.
"I am not talking about unlucky yellow cards, I consider the yellow card Leigh Halfpenny had against Australia in December to have been a little bit unlucky, so I am not judging that as a stupid yellow card.
"But we have had yellow cards in the past which I think have been a little bit unnecessary.
"So I have asked the players to decide what sort of deterrent we need, as I have held my hands up as a coach and said that whatever I am saying at the moment is not working to a couple of individuals, in terms of me having criticised them publicly in the past and then being criticised myself for doing that.
"I did suggest a fine of £20,000-£30,000 could be relevant, but I don't think they were not too keen on that.
"We need to come up with something relevant and we will come up with something in the next few weeks that the squad are happy with."
