Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional testing methods using physical vibrations and test CDs are used, then the player's response to vibrations can be evaluated, but the testing process becomes costly and labor-intensive
Solution Approach 1:
The patent creates a simulated anomaly signal that copies the characteristics of actual vibration-induced signal disruptions without requiring physical vibrations or special test CDs. The simulator generates digital signals that replicate the effects of physical anomalies, allowing virtual testing of the player's response to vibrations.
Solution Approach 2:
The patent replaces the mechanical vibration testing system with a digital signal simulation system. Instead of physically vibrating the CD player and using test CDs with defects, the system uses software to generate and process simulated anomaly signals through the player's processing circuitry, eliminating the need for mechanical manipulation.
