Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional display systems are used for shooting ranges, then the device complexity is low, but the information clarity and visualization quality are insufficient
Solution Approach 1:
The display device is segmented into multiple independently controllable luminous fields (e.g., five separate fields for five targets), each capable of displaying different information states (hit/miss indicators, timing information). This segmentation allows clear visualization of multiple shooting results simultaneously while maintaining manageable system complexity through modular control.
Solution Approach 2:
The patent employs color changes in the luminous fields to convey different shooting results and timing states. Different colors indicate different outcomes (e.g., green for hit, red for miss), and color transitions or flashing patterns communicate timing information. This visual encoding significantly improves information clarity without requiring complex display hardware.
2Loss of information
If detailed shooting results and timing information are displayed continuously, then the information completeness is improved, but the energy consumption increases
Solution Approach 1:
The display device uses periodic flashing of luminous fields to convey timing information and maintain visibility without continuous high-power operation. The luminous fields flash at specific intervals to indicate timing states (e.g., remaining time, time expired), allowing the system to communicate complete information while reducing overall energy consumption compared to continuous illumination at full brightness.
Solution Approach 2:
The display system dynamically adjusts the state of luminous fields based on real-time shooting results and timing information. Luminous fields are activated only when relevant information needs to be displayed, and their brightness or flashing intensity is modulated according to the current competition state. This dynamic operation ensures complete information delivery while optimizing energy usage by avoiding unnecessary continuous display.
3Illumination intensity
If the display is designed to be visible from long distances, then the visibility is improved, but the illumination intensity required increases
Solution Approach 1:
The display device implements local quality by directing illumination primarily upward and outward from the display location, rather than emitting light in all directions including toward shooters. The luminous fields are positioned and oriented to maximize visibility distance for spectators and officials while minimizing direct glare exposure to shooters. This localized illumination strategy achieves long-distance visibility without creating harmful glare conditions.
Solution Approach 2:
The display uses periodic flashing rather than continuous illumination to achieve visibility from long distances. The intermittent flashing pattern allows the human eye to detect the display from greater distances while the duty cycle remains low, significantly reducing overall light output and preventing glare to shooters during the non-flashing periods.
