Which design approach promotes ease of fault finding and maintenance in manufacturing?

• A. Using standardised parts and sizes
• B. Design for modularity (fault finding) and maintenance
• C. Use adhesive rather than mechanical fixings
• D. Injection mould where possible (Avoid wastage processes)

Answer: (B)

Design for modularity and maintenance. Breaking a product into discrete, interchangeable modules with clear interfaces lets faults be isolated to a specific module. When something goes wrong, you can quickly swap in a known-good module,, test the system, and restore function with minimal downtime. This approach also supports easier access for routine service, faster diagnosis, and simpler spare-parts management, which is exactly what makes fault finding and ongoing maintenance much more efficient. Using standardised parts helps production efficiency, but it doesn’t inherently make fault diagnosis and maintenance easier. Adhesives make disassembly hard, so fault finding becomes more difficult. Injection moulding choice affects production waste, not directly the ease of fault finding or maintenance.
