====== Esther's Water Bottle Parametric Modeling ======



In this project, I created water bottle parametric model that can be easily changed to fit different type of user in different environment. My base three configuration is for: Biker in San Francisco, Child in Ankorage, and Elderly in Dubai. The design model is adjastable for each user by implementing different parameter on: Mobility, Temparature, and Dryness.
The mobility factor indicate how much the user is mobile. As the user is more active, the higher mobility factor need to be input. However, if the user has lower quality of movement such as child or elderly,the low mobility factor has to be applied.
The temparature factor is for Thermostat. The bottle thickness will be increased depending on the cold temparature between 32F and -76F.
The dryness factor is for dry location which requires a lot of water to quench a user. As the location is more dry, higher number has to be applied as a dryness factor so that the volume of the water bottle is increased, and the bottle opening gets bigger for really thirst user.




==== Description of design drivers / goals ====




  
* **Goal 1** – create easy grippable water bottle for different user

* **Goal 2** – Create stable design.

* **Goal 3** -  maintain good water quality

* **Goal 4** - Quench the user in any environmant

==== Parametric variations: Images ====

Here are some examples of what happens when I vary the parameters....

**Unexpected case 1**

{{:esther:unexpected_case1.png?500|}}

The opening(straw) goes to inside of cap.


     
**Unexpected case 2**     

{{:esther:unexpected_case_1.png?500|}}

When the bottle height is too small, the curve make strange configuration.


==== Lessons learned ====


  * Check its configuration at each step before setting the next constraint


  * To have more flexibility, limit the number of constraint

  * Each workbench has different functions



  * Limited use of formula function (it is not an excel sheet)


  * Flexible use of workbench


  * Difficulty to find overlapped constraint(violet)
