Summary
The rise in remote work increased computer use and musculoskeletal issues like neck and back pain. This study designed ergonomic computer chairs using Indian anthropometric data to address these problems.
Area of Science:
- Ergonomics
- Biomechanics
- Product Design
Background:
- The COVID-19 pandemic led to a significant increase in remote work and computer usage.
- This surge in computer use has been linked to a rise in musculoskeletal disorders, particularly neck and back pain.
- Poor workstation ergonomics is a primary cause of these work-related musculoskeletal issues.
Purpose of the Study:
- To design and evaluate computer user chairs tailored to Indian anthropometric standards.
- To address the growing problem of musculoskeletal discomfort among remote computer users.
- To improve workstation ergonomics for enhanced user comfort and health.
Main Methods:
- Development of three distinct chair models using CATIA V5 software.
- Application of biomechanical analysis and Rapid Upper Limb Assessment (RULA) for ergonomic evaluation.
- Structural analysis using ANSYS to ensure physical integrity under static loads.
Main Results:
- The designed chairs were found to be structurally sound under static conditions.
- Biomechanical and RULA analyses provided insights into the ergonomic suitability of the designs.
- The study established a foundation for developing chairs based on specific anthropometric data.
Conclusions:
- Ergonomically designed chairs based on Indian anthropometric data can help mitigate musculoskeletal issues associated with prolonged computer use.
- The developed chair models demonstrate structural integrity for static use.
- Further research can refine these designs for dynamic conditions and broader user populations.
