Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a computer screen is used to display jog wheel position information, then information can be displayed, but latency causes visual distraction and reduces precision for rapid actions like scratching
Solution Approach 1:
The display system is segmented into multiple independent LED indicators arranged in concentric circles, each representing specific angular positions. This segmentation allows direct visual correlation between physical jog wheel position and displayed information without requiring screen refresh cycles, eliminating latency while maintaining precise angular position indication.
Solution Approach 2:
LED indicators serve as an intermediary between the jog wheel's physical position and the information display system. The LEDs provide real-time visual feedback by directly reflecting the angular position through their spatial arrangement, acting as a mediator that eliminates the latency inherent in computer screen displays while preserving precise position information.
2Device complexity
If a single circle of LEDs is used for angular position display, then the structure is simple, but the precision and readability are insufficient
Solution Approach 1:
The display is segmented into multiple concentric circles of LEDs, where each circle provides a different level of angular resolution. The inner circle offers coarse angular divisions while the outer circle provides finer divisions, allowing precise angular position indication through the combined information from multiple segmented display elements without excessive structural complexity.
Solution Approach 2:
The display transitions from a single-dimensional circular arrangement to a multi-dimensional concentric circular structure. By adding the radial dimension with multiple circles at different radii, the system achieves higher angular position precision while maintaining rotational symmetry and avoiding linear complexity increases.
3Measurement precision
If the jog wheel display provides detailed angular information, then precision is improved, but the DJ must look at the display instead of the audience or hands
Solution Approach 1:
The display provides localized visual feedback directly at the jog wheel location rather than requiring the DJ to shift attention to a separate screen. The LED indicators are positioned in the immediate visual field of the DJ's hands, allowing precise angular position information to be obtained without breaking focus on the performance or audience.
Solution Approach 2:
The system implements immediate visual feedback through LED indicators that directly reflect the current angular position of the jog wheel. This real-time feedback loop allows the DJ to maintain precise control and awareness of position without needing to look away from the performance area, as the feedback is provided locally and continuously.
