Containment vs Accessibility
Design modular, quickly reconfigurable containment systems that preserve mandatory hazardous-substance isolation during operation while enabling safe, efficient maintenance access.

Regulations
Business Context
Automotive processes involving chemicals, fluids, fumes, high voltage, heat, or moving equipment may require physical containment to prevent exposure and uncontrolled release. Stronger enclosures improve protection but can restrict inspection, cleaning, adjustment, and maintenance access, increasing intervention time and encouraging removal of protective barriers.
Automotive TRIZ Resolution
Containment and access do not need to exist simultaneously in the same physical state. Modular panels, service openings, movable barriers, isolated access zones, remote inspection, and automatic shutdown conditions can preserve containment during operation while creating controlled accessibility when intervention is required.
Applicable TRIZ Principles
Principle 1 – Segmentation divides containment into independently accessible sections.
Principle 15 – Dynamics allows protective structures to change configuration during controlled maintenance.
Principle 24 – Intermediary uses remote sensing or inspection systems to provide information without direct access.
Expected Outcome
Effective hazard containment
Faster maintenance access
Reduced intervention time
Lower risk of protection being bypassed
Decision Indicators
Early indicators that this contradiction is limiting operations include:
Routine inspections require removal of major protective structures.
Maintenance teams frequently work around difficult enclosure designs.
Containment substantially increases repair duration.
Protective barriers are repeatedly removed for operational access.
Inspection requires unnecessary exposure to hazardous areas.
Monitoring these indicators helps determine where operational containment and maintenance access should be separated by time or configuration.
