  1. Ergonomics (ms306)Box Cutter Project Dicle Ceylan Gizem Gürdeniz Pelin Porsuk İrem Öksüz Funda Şentürk Mert İnanoğlu

  2. Outline • What is box cutter, area of usage • Importance of ergonomic design of box cutter • Ergonomic principles and ergonomic principles of boxcutters • Anthropometry • Examples-pictures • Our ideas and it’s solidworks drawing • References

  3. What is box cutter • Cutting Tool • Use to open boxes and to cut thin, lightweight materials. • Commonly used in factories • Generally, 22 mm wide and 75 to 100 mm long • Adjustable blade extention from the handle

  4. Importance of ergonomic design of box cutter • Decrease injuries • Increase productivity • Less time consuming • Should be lightweight • Easy to use and carry • Sharp areas should be covered with appropriate material

  5. Major ergonomics concern of hand-tool design • Weight of the tool • Power • Handles • Handle Shape • Diameter • Length • Seperation betweenhandles • Power tool triggers • Materials and texture of handles • Vibration

  6. Anthropometry • Study of dimensions and physical characteristics of human body(weights,volumes, centres of gravity, inertial properties of body segments and strengths of various muscle groups) . • Application areas

  7. Anthropometric Data • Measurement Types Static Anthropometry Dynamic Anthropometry Skeletal Dimension Body in Motion

  8. Methodology for Determining the survey population According tovaried aged groups Divide people according to; • Gender • Usage of the right-handed/left-handed sides

  9. DETERMINING DIMENSIONS

  10. Collected datas from females

  11. Collected datas from males

  12. Determining the dimensions of the box cutter • For 95th percentile: + * z • For 5th percentile: – * z • Z value = 1,645 for 95th and 5th percentile

  13. Comparison of the basic version of the product with the one we created

  14. Bent • Decrease the motion and stress on wrist • Decrease fatique • Position of the clips • No need to change between two fingers

  15. Technical drawing (solidworks)

  16. Reference • Tayyari, F., Smith, J. L., (1997), OccupationalErgonomics, GreatBritain: ChapmannandHall. • Lecture Slides
