Description¶

The study recommends designing a new combination phonograph-cassette machine from "standardized and compatible subassemblies" usable in both a Revised Talking Book Machine and a Revised Cassette Book Machine, with new designs for motor, amplifier, speaker, tone arm, turntable-cassette assembly and cases. Buying these subassemblies in large quantities "will provide a reduction in the cost and time utilized in the repair of malfunctioning equipment," and standardized components are expected to reduce Mean Time To Repair and improve Mean Time Between Failures.

Design Implications¶

Context¶

Requirements¶

• New designs for compatible subassemblies (motor, amplifier, speaker, tone arm, turntable-cassette assembly, cases)
• Procurement procedures revised to permit mass purchase of compatible subassemblies

Constraints¶

Target Learners¶

• Blind and physically handicapped readers served by the DBPH machine-lending network

Target Learning Goals¶

• Reliable access to working playback equipment for recorded reading materials
