Introduction Flashcards
Those who employ agents of technological skills and facility and make use of the creative energies to bring about some sort of advantages that are useful to
man.
Designers
Highly innovative and cross-disciplinary
process that uses the most acceptable aesthetic,
efficiency, and economical means to satisfy people’s
need.
Designing
n It includes the process of organizing the methodology needed to
proceed from concept to final product, determining which
technological resources to use, the economics of production and
operation, as well as the human and social factors that will be
needed.
Philosophy design
carried out using mathematical formula
and other engineering principles.
Rational design
based upon empirical formula derived from existing practices and past experiences.
Empirical design
involved other considerations like aesthetics, ergonomics, and production aspect.
Industrial design
Does not exist before and is only
done by few dedicated designers who have sufficiently high order personal qualities. This also requires a lot of research undertakings, experimental activities, and creative brains.
Original design
More concerned of the adoption of existing designs. This does not demand special knowledge or skills. Problems can be solved with ordinary training.
Adaptive design
Begins with an existing design
but the final result may differ a bit from the initial product.
Development design
Used to include uncertainties in the design.
Factor of safety
-Excessive strength and oversized machines are usually wasteful
in engineering design.
-Machine to be designed, if possible, should have 99.9% reliability
-Continuous replacement of defective machine components may keep the design more reliable and economical
Reliability
-Technical reports approved and recommended for practice by
engineers
- It is a mechanism for interchanging machinery parts thus resulting in a lower product cost to consumers.
Standards
Sketches are prepared showing the machine to be designed and
explaining how it works.
Conceptual design preparation
Searches for existing machines similar to the machine under
consideration. Results of previous studies can help reduce the
required parameters in developing the machine
Literature search
Design calculations for the different parameters needed in the design should be done in order to arrive into the nearest possible dimension and performance as expected.
Preparation of design calculation
Materials to be used as per design must be prepared prior to
fabrication. Fabrication tools and equipment must be available so
that the machine can be well fabricated as per design.
Preparation of Materials and Tools/Equipment to be Used In the Fabrication
Proto-type unit of the machine will be first fabricated to determine its performance once tested.
Fabrication of proto-type unit
Testing is conducted to find out whether the machine parts work
and to determine its performance whether the expected result is
achieved or not.
Conduct of Functional and Performance Testing of
the Machine
Machine parts that need modification and improvement after testing must be done until the designer is fully satisfied
Modification and Improvement of Parts of the Machine
Actual field testing and evaluation of the machine at the target
user must be done to further check if the machine can fully
provide the solution to the requirements of target beneficiaries
Conduct of pilot-testing
Final model is built to check further its acceptability to users
before its commercialization.
Building of Final Model for Commercialization
facilitates calculations, drafting, and writing.
Computer
reference materials, standards, catalogs, manuals, etc.
Technical handbooks
This can be outsourced from other fabrication shops.
Tools and equipment for fabricating proto-type and final unit of the machine.
to carryout functional testing, evaluation, improvement and modification that need to be done.
Test instruments
to carryout the design development
Funds
calculations, drawings preparation, and testing and evaluation
Manpower support
to choose the right decisions during the process of designing and development of the machine
