Regulations
Business Context
Compact production equipment reduces floor-space requirements and can shorten material movement within automotive plants. Dense packaging, however, can restrict access to motors, sensors, valves, tooling, electrical systems, and wear components, increasing maintenance duration.
Automotive TRIZ Resolution
Automotive TRIZ separates operating space from maintenance space. Sliding assemblies, removable modules, external service points, accessible diagnostic connections, and components that move into service positions can maintain compact equipment during production while creating temporary access during maintenance.
Applicable TRIZ Principles
Principle 1 – Segmentation divides equipment into independently accessible modules.
Principle 7 – Nested Doll uses available equipment volume efficiently.
Principle 15 – Dynamics allows components to change position when maintenance access is required.
Expected Outcome
Smaller equipment footprint
Improved maintenance accessibility
Shorter intervention time
Better utilization of production space
Decision Indicators
Early indicators that this contradiction is limiting operations include:
Routine component replacement requires major equipment disassembly.
Technicians cannot reach common service points directly.
Compact equipment consistently produces longer repair times.
Maintenance access determines equipment spacing on the production floor.
Components must be removed primarily to reach other components.
Monitoring these indicators helps identify where maintenance space can be temporary rather than permanently included in equipment geometry.
