What political innovations did the 1787 constitutional convention develop for the new nation?

On May 25, 1787, state delegates met at the Pennsylvania State House in the city of Philadelphia, George Washington was appointed the president of the Convention, and sought to reach an agreement with the states to renew the original constitution of 1777, which gave no power to Congress to regulate trade and taxes, which made the country bankrupt. Charles Pinckney drafted the Virginia Plan, but it was not accepted, and New Jersey delegate William Paterson presented his own counterpart plan, called "New Jersey Plan." Finally, Roger Sherman created the '' Connecticut Commitment ' and in September 1787 the final agreements were signed, which would empower the Congress to control taxes, commerce, money and the army, while respecting the individuality of the states.
