You can also use filtering on your Archtitecture requirement like
"(architecture.instate=your_instance_name)".
Then only your intended instance's Architecture reference will be injected
into your Array, or you can use just single reference.
As i understand your situation, something like following may help:
@Bind(filter="(architecture.instance=your_instance_name)")
public void bind_instance(Architecture arch)
{
// Will be called when instance having specified "your_instance_name"
is activated with its Architecture reference.
