Overview
This video demonstrates competencies SIT012B and 10050A by applying a computability diagnosis to a real-world case of a small store. The presenter, Jim Vázquez Sánchez, details a process for analyzing and improving the ergonomics and efficiency of lifting boxes from a pallet. The video covers initial mapping using flowcharts and process maps, diagnosis using tools like Pareto charts and RULA assessments, and proposes Industry 4.0 solutions such as sensors and exoskeletons, along with considerations for the human factor, well-being, sustainability, and ethics.
Key takeaways
- Ergonomic Assessment: The initial state involves a worker bending and flexing their trunk and neck to lift a 2kg box from a low pallet, resulting in significant trunk (50º) and neck (25º) flexion, identified as an ergonomic bottleneck.
- Diagnosis Tools: The diagnosis phase utilized Pareto analysis, revealing that lower back pain and shoulder fatigue are the primary reported discomforts. A time study showed the lifting process takes 25 seconds instead of the standard 18, indicating inefficiency due to poor posture. The RULA assessment yielded a score of seven, suggesting immediate intervention is needed.
- Industry 4.0 Solutions: Proposed solutions include portable Lot sensors to detect excessive trunk flexion and alert the worker, and passive exoskeletons to reduce lumbar load by up to 40%. While expensive, these are presented as cost-effective in preventing injuries.
- Human Factor Integration: The approach incorporates human factor elements such as human-machine collaboration, gamified microlearning for posture and equipment use, and design thinking centered on operator input.
- Well-being and Sustainability: The proposal emphasizes worker well-being through active breaks and sustainability by adhering to relevant ergonomic (NOM-036-STPS-2018) and safety (ISO 45001) standards. An ethical consideration addresses the investment dilemma of technology, suggesting a cost-benefit analysis where injury costs outweigh technology expenses.
