Designing an arcade machine for easy repairability involves several critical factors. First, modular components allow for quick replacement of faulty parts without disassembling the entire machine. Using durable materials, such as high-quality plastics and metals, ensures longevity and reduces wear and tear. Additionally, accessible wiring and labeled connections simplify troubleshooting and repairs. Standardized parts and tools further streamline maintenance, minimizing downtime. Finally, clear documentation and user-friendly design empower operators to handle repairs efficiently, keeping the arcade machine in top condition with minimal effort.
