Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If traditional single optical sensor reading method is used, then reading precision can be maintained, but reading speed decreases and multiple passes are required
Solution Approach 1:
The patent divides the reading function into multiple parallel optical sensors, each responsible for reading a specific track. This segmentation allows simultaneous reading of multiple tracks in a single pass, eliminating the need for multiple sequential passes and significantly improving reading speed.
Solution Approach 2:
The patent combines multiple optical sensors into a single array reader system that operates in parallel. By merging the reading capabilities of multiple sensors and coordinating their outputs, the system achieves fast simultaneous reading of multiple tracks while maintaining the precision of individual sensors.
2Productivity
If array of optical sensors is used to read multiple tracks simultaneously, then reading efficiency improves, but alignment precision becomes more difficult to maintain
Solution Approach 1:
The patent incorporates feedback mechanisms where the positions and outputs of individual optical sensors are continuously monitored and adjusted. This feedback allows the system to maintain precise alignment across all sensors in the array, ensuring that each sensor accurately tracks its designated track despite variations in media positioning or sensor drift.
Solution Approach 2:
The patent employs dynamic adjustment capabilities where the optical sensor array can adapt its positioning and focus in real-time. This dynamic behavior allows the system to maintain measurement precision across all sensors while simultaneously reading multiple tracks, balancing productivity gains with alignment accuracy.
3Productivity
If multiple optical sensors are arranged in array, then simultaneous reading of parallel tracks is enabled, but device complexity increases
Solution Approach 1:
The patent designs the optical sensor array with universal components that can be applied across multiple tracks. By using identical or similar sensor elements repeated in an array configuration, the system achieves simultaneous reading capability while managing complexity through standardization and modularity of the sensor units.
4Measurement precision
If precise alignment mechanism is implemented for accurate reading, then reading accuracy improves, but ease of operation decreases
Solution Approach 1:
The patent implements self-aligning features where the optical sensor array automatically adjusts and locks onto the tracks without requiring manual intervention. The system performs its own alignment and positioning tasks, maintaining high reading accuracy while simplifying operation for the user who only needs to load the media.
