Some Engineering Aspects of Amateur Projection Equipment for the Mass Market

The mass market necessarily is a price market, since only in the low-price brackets are sufficient purchasers found to warrant large volume production. — Low cost can be achieved while high relative value is maintained, only if the engineering adheres carefully to these fundamentals: (a) elimination of unnecessary features; (b) determination of acceptable minimum levels of performance; (c) provision for attractive external appearance; (d) design of parts for mass production by proper selection of dimensional tolerances, careful tooling to insure such tolerances, and the use of suitable materials; (e) the establishment of economical assembly-line procedure by considering assembly problems from the inception of parts design, providing accurate assembly fixtures, and maintaining adequate process inspection throughout manufacture.
