Patterns are awesome. With great powers comes great responsibility.

TL;DR: Don't abuse patterns.

Problems

• Over Design

• Readability

Solutions

1. Measure the tradeoff of patterns usage.

2. Create solutions based on real world names (essential) over architecture (accidental).

3. Choose good names.

4. User MAPPER technique to find bijection real entities.

Sample Code

Wrong

public final class FileTreeComposite {
    //name should be inferred from behaviour
}

public final class DateTimeConverterAdapterSingleton {
    //
}

public final class PermutationSorterStrategy {
    //
} 

public final class NetworkPacketObserver {
    //
}

public final class AccountsComposite {
    //
}

Right

public final class FileSystem {
    // These names map 1:1 to real world concepts
}

public final class DateTimeFormatter {
    //
}

public final class BubbleSort {
    //
}

public final class NetworkSniffer {
    //
}

public final class Portfolio {
    //
}        

Detection

It would be very difficult to create automatic detection rules.

A class name with more than one pattern on it, is a warning.

Conclusion

Chose when to apply a pattern solution. You are not smarter for using too many patterns. You are smart if you choose the right opportunity for everyone.
