Topic 6 Product Design

  1. 1. Product Design Topic 6
  2. 2. The Responsibility of the Designer <ul><li>The designer, by instigating technological change, is implicated in the resultant social consequences. Commonly these are seen as unexpected or unwanted effects arising from a new product, technique or system. This topic focuses on the designer's responsibilities to the consumer/user, the client or manufacturer and society, and how these responsibilities can sometimes cause conflict . </li></ul>
  3. 3. Ergonomics 6.1
  4. 4. Definitions <ul><li>Ergonomics – The application of scientific information concerning the relationship of human beings to the design of objects, systems and environments </li></ul><ul><li>Anthropometrics – The aspect of ergonomics that deals with body measurements, particularly those of size, strength and physical capacity Click </li></ul><ul><li>percentile range - That proportion of a population with a dimension at or less than a given value. </li></ul>
  5. 5. Ergonomics <ul><li>ergonomics is a multidisciplinary approach that encompasses </li></ul><ul><li>anthropometrics </li></ul><ul><li>psychological factors </li></ul><ul><li>physiological factors. </li></ul>
  6. 6. Ergonomics <ul><li>Psychological factors (smell, light, sound, taste, texture and temperature) have significant relevance to ergonomics </li></ul><ul><li>Individuals react differently to sensory stimuli. Efficiency and comfort are affected by such factors. </li></ul>
  7. 7. Ergonomic Physiological Factors <ul><li>Normally deals with bodily tolerances such as: </li></ul><ul><li>Fatigue </li></ul><ul><li>Comfort </li></ul><ul><li>A persons tolerances or comfort levels are different when tired </li></ul>
  8. 8. Perception <ul><li>Quantitative data may be used in a design context relating to psychological factors, but individuals vary in their reaction to the data. For example, one person will find a room temperature comfortable while another person will find it uncomfortable, though the temperature is constant. </li></ul>
  9. 9. Percentile Ranges <ul><li>What is a design context where the 5th-95th percentile range has been used? </li></ul><ul><li>mass-produced clothing - Clothes are produced in a range of sizes based on the 5 th -95 th percentage range of a particular user group </li></ul><ul><li>What about a context where the 50th percentile has been used? </li></ul><ul><li>Desks, washing machines, and cookers are designed around the 50 th percentile so they are all a standard height regardless of the brand. </li></ul>
  10. 10. Percentile Ranges <ul><li>There are limitations in using the 50th percentile as a means of designing for the &quot;average&quot; person. </li></ul><ul><li>The 50th percentile refers to one particular dimension. For example, someone may be average in height but not average in other dimensions </li></ul>
  11. 11. Percentile Ranges <ul><li>You should be able to identify specific design contexts where the designer would use percentile ranges for particular user groups. </li></ul><ul><li>Example: toys for young children </li></ul>
  12. 12. The Designer and Society 6.2
  13. 13. Responsibilities of the Designer <ul><li>What are some of the moral and social responsibilities of designers in relation to green design issues? </li></ul><ul><li>Consider issues relating to: </li></ul><ul><li>waste </li></ul><ul><li>Pollution </li></ul><ul><li>Resources </li></ul><ul><li>market forces </li></ul><ul><li>wealth creation. </li></ul>
  14. 14. Planned Obsolescence <ul><li>planned obsolescence – A conscious act either to ensure a continuing market or to ensure that safety factors and new technologies can be incorporated into later versions of the product </li></ul><ul><li>planned obsolescence influences the design specification of a product in: </li></ul><ul><li>materials and construction </li></ul><ul><li>durability </li></ul><ul><li>ease of maintenance. </li></ul>
  15. 15. Planned Obsolescence <ul><li>There are both advantages and disadvantages to producer and consumer </li></ul><ul><li>consumer choice </li></ul><ul><li>Value </li></ul><ul><li>R&D </li></ul><ul><li>product life cycle. </li></ul>
  16. 16. Fashion <ul><li>Fashion – A style or trend </li></ul><ul><li>Planned obsolescence has a definite timescale; fashion is less predictable. Both may be present. For example, a certain colour may be fashionable for a car but this does not affect materials or technological obsolescence . </li></ul>
  17. 17. Influence on the Product Cycle <ul><li>What is the influence of fashion and planned obsolescence in relation to the quality and value of a product? </li></ul><ul><li>Consider whether &quot;designer&quot; products are better quality than cheaper brands of the same product, and also question the values of a &quot;throw-away society&quot;. </li></ul>
  18. 18. Aesthetic Considerations <ul><li>aesthetic considerations affect the design of products. </li></ul><ul><li>shape and form </li></ul><ul><li>texture </li></ul><ul><li>colour </li></ul>
  19. 19. Internal Conflicts <ul><li>What conflict might a designer face when attempting to balance form with function in the design of products? </li></ul><ul><li>Automobiles </li></ul><ul><li>Cell phones </li></ul><ul><li>Other areas? </li></ul>
  20. 20. The End Topic 6
