design pattern create object from several object

hi can someone give me advice, what design pattern or best practice that good for my problem, in my service layer i have many method which construct object from several object. such as:

Order order = toOrder(A a, B b, C c);
Order order = toOrder(D d, A a)

it become bloated in my service layer, i read about converter and mapper, but is it limited about 2 object ? like create or mapping to object A to object B only

workaround that i can think is create a constructorHelper class that will consist of static method, but it will can cause a issue like dao pattern other developer will put many method without restriction
