a makeshift solution
Something 'makeshift' is a temporary, improvised, and usually insubstantial expedient, contrived in response to an urgent need or emergency. Simply put, it is a substitution for something better that is currently unavailable or not yet conceived. It is used in both a social and professional setting and is similar to the phrases 'rough-and-ready,' and 'cobble together.'
