An ergonomic workstation design for the trimming section of Globe Plastics Inc.

Executive Summary. In the pursuit of finding better solutions, ergonomics aims to add value through advancement of human working conditions. It has been an age-old practice for workers to adjust to their working environment. However, awareness and the impact of ergonomics have shown that exactly the opposite is much better. More and more, applications of ergonomics are emerging in various industries. Globe Plastics is the latest company to share with this development. The focus of the study is on the 30 male trimmers of the packaging company. Three general body parts emerged as the most stressed areas. They are: the trunk, the neck and the legs, particularly the left knee and the left foot. The prototype came as the product of the study. It is designed to fit the body dimensions of trimmers. The survey indicates that the prototype successfully reduced, and in some body parts, eliminated the discomfort and pain endured by the trimmers. These data were further supported by the RULA, postural analysis and biomechanical tests. The output of the company is largely reliant on the machine\u27s capability. Nonetheless, the new workstation significantly advanced working conditions, and most importantly the quality of the worker\u27s life. The seat was designed with a height of 16 inches. Its depth and width are both 16 inches. These improved the leg positions of the trimmer. Seat cushions of 2 inches further added comfort to the buttocks. The seat was also sloped forward with ten degrees to support the back when trimming. Table height is 32 inches, tilted 44 degrees towards the trimmer. This design prevents the neck from experiencing stress from excessive flexion. To further support the neck and the lower back, the catch bin base is likewise tilted towards the trimmer with an angle of 23 degrees. This allows the trimmer to easily pick up the bottles. In addition, and importantly, posture 111 has been eliminated by shortening the packing stand and placing it near the trimmer. This further reduces the risk of low back pain
