Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If current range finder technologies are used for bows, then distance measurement capability is provided, but accurate display of distance measurements on bow sight pins is insufficient
Solution Approach 1:
The display system is segmented into multiple individual LEDs, each corresponding to a specific distance range and bow sight pin. This allows independent control and mapping of distance measurements to specific visual indicators, enabling accurate distance display while maintaining manufacturing flexibility through modular LED assembly.
Solution Approach 2:
The range finder assembly integrates multiple functions into a single device: distance measurement via laser range finding, signal processing through microcontroller, and visual display through LEDs. This multi-functional integration improves measurement accuracy while simplifying the overall system compared to separate components.
2Loss of information
If display pins are coupled with LEDs using optical coupling assembly, then accurate range display is achieved, but device complexity increases
Solution Approach 1:
The optical coupling assembly acts as an intermediary component that efficiently transfers light signals from LEDs to the bow sight pins. This dedicated optical interface ensures accurate range signal transmission while isolating the complexity of the optical coupling mechanism from both the electronic control system and the mechanical bow sight components.
Solution Approach 2:
The optical coupling assembly is integrated within the housing structure, with LEDs positioned inside the housing and optically coupled to the bow sight pins. This nested arrangement consolidates multiple components (LEDs, optical couplers, housing) into a compact integrated unit, reducing overall device complexity while maintaining signal transmission accuracy.
