Prototypes 302h Flashcards
Why build a prototype?
Aesthetics
Compare, test and choose materials
Compare design and construction details
Internal capacity
External size
Production planning
Time/motion cost analysis
Choose hardware
What is the reason cited if designers request a prototype to confirm appearance or suitability of a material?
Aesthetic
If you prototype a small part of a project to test the function of hardware or compare two materials, what are you actually doing?
Making a sample
What do designers sometimes do to get an idea of the appearance of a piece before anything is built?
3d computer simulation
Why might several prototypes be built of different materials?
Test suitability and performance of materials under extreme conditions
If citing production planning as a the reason for building a prototype, what things may be confirmed by the prototype?
Joinery choices and time/motion study
Do architects plans usually contain enough detail to build complex mill work?
No, they only give general information about overall appearance and function
With large irregularly shaped items, what do you often have to do to determine size, shape, and construction?
Full size layouts
If using a computer to plot at 1:1 scale as a layout, how can you be sure the plot is accurate?
Calibrate plot by direct measurement and making adjustments to the scale
How can you accurately lay out curves of a specified radius with hand tools?
Improvising a large beam compass
When using components supplied by other manufacturers should you order the components after you’ve built your prototype?
No, order other components first, you may have to modify prototype to obtain required clearances and fit
Why is it important to test a topcoat that will be subjected to extreme conditions?
They may not perform as expected and must be tested under a simulation of conditions
What step in a large casework prototype confirms that all sizes are correct and that all parts fit and work properly?
Staging
Why would a window company build in one region and test in another?
Prove dimensional stability of chosen wood under actual conditions of use
When would you make a prototype of lesser quality materials?
To test a design idea not related to material choice to save money
