Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional illuminated displays with limited display segments are used, then device complexity is reduced, but reticle pattern variety and resolution are limited
Solution Approach 1:
The display is segmented into individually addressable micro-LED elements arranged in a fine pixel grid, allowing independent control of each pixel to create diverse reticle patterns while maintaining manageable system complexity through modular addressing schemes
Solution Approach 2:
The micro-LED display system serves multiple functions: it can generate various reticle patterns, provide illumination, and display aiming information through a single unified display structure, eliminating the need for separate specialized display components
2Manufacturing precision
If low-resolution LED displays are used, then manufacturing cost is reduced, but visual clarity and brightness are insufficient
Solution Approach 1:
The system changes the physical parameters of the display by using micro-LED technology with smaller pixel sizes and higher density, which enables both higher resolution and improved brightness through increased light emission density while maintaining manufacturing feasibility
3Reliability
If visual artifacts are present in the display, then device complexity is reduced, but user distraction and aiming accuracy are worsened
Solution Approach 1:
The system incorporates control logic that monitors and adjusts LED activation to eliminate visual artifacts, ensuring clean reticle patterns without distracting display elements, thereby improving aiming accuracy through artifact-free presentation

AI summary
A sighting device, such as a riflescope, a reflex sight, or a spotting scope, having a display device including an addressable, emissive collection of micro display elements for generating a finely pixelated, high-resolution aiming mark. The sighting device includes a controller coupled to the display device to selectively power one or more of the display elements to generate the aiming mark. The micro display elements may be inorganic light-emitting diodes (LEDs) having a pixel size of 25 μm or less, and the display elements may be arranged at a pixel pitch of 30 μm or less.
