Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional augmented reality or heads-up display technologies are used for firearms, then aiming capability is improved, but device complexity and cost increase due to expensive computational components
Solution Approach 1:
The patent extracts and removes the expensive computational components (GPUs, complex processors) from the firearm sight system. Instead, it uses simple, inexpensive accelerometers to sense firearm orientation and directly maps this data to reticle positioning on the display, eliminating the need for complex computational processing while maintaining aiming capability.
Solution Approach 2:
The patent replaces expensive, complex computational components with cheap, simple accelerometers that can be easily manufactured and integrated. These inexpensive sensors provide sufficient data for reticle overlay without requiring costly processing hardware, making the system cost-effective and accessible.
2Adaptability or versatility
If see-through display systems are implemented in firearms, then tactical versatility is improved, but manufacturing complexity increases
Solution Approach 1:
The patent merges the firearm sight system with standard wearable display technology (smart glasses). By integrating the accelerometer data from the firearm with the display system already present in consumer AR glasses, the patent achieves tactical versatility without requiring custom-manufactured specialized components, thereby simplifying production.
Solution Approach 2:
The patent uses universal, off-the-shelf components (accelerometers, standard AR glass displays) that can serve multiple functions and applications. The same hardware platform can be used across different firearm types and tactical scenarios, reducing manufacturing complexity through standardization and multi-functionality.

AI summary
Augmented reality eyewear are provided removing need to aim-down-sight while using a firearm. Eyewear have accelerometer sensors outputting a “view angle” that is compared with line of sight or “head angle” and true horizon. A camera system outputs the target distance. A firearm equipped with one or more accelerometers output a trajectory. With the firearm and goggles within an arms length proximity of one another, data points can be combined to create a full 3D spacial image of the bullet's path. Target distance determines the length of the trajectory and “termination coordinates” describing the projectile's target in space relative to the user's personal coordinate system (i.e., view angle). Relative termination coordinates can then be delivered to the goggle drivers. The termination coordinates are converted to a pixel command generating an illuminated aiming reticle that corresponds with the direction a firearm is pointing and overlaid on the target.
