Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual distance entry is used in standalone aiming systems, then device complexity is reduced, but measurement precision and resolution deteriorate
Solution Approach 1:
The aiming system calculates distance automatically using its own clinometer measurements and ballistics charts without requiring external rangefinders or manual input. The system serves itself by computing the firing distance based on the relationship between initial angle of elevation and instantaneous angle of elevation, eliminating the need for separate distance measurement devices while maintaining precision.
2Ease of operation
If complete grid sight is used, then ease of operation is improved, but measurement precision and resolution deteriorate
Solution Approach 1:
The patent replaces mechanical grid sights with an electronic computing system that processes clinometer data through ballistics charts to determine distance and aiming angles. This substitution eliminates the limitations of mechanical grids while maintaining ease of operation through automated calculations and digital display.
3Device complexity
If standalone aiming system without rangefinder communication is used, then device complexity is reduced, but measurement precision deteriorates
Solution Approach 1:
The aiming system calculates distance automatically using its own clinometer measurements and ballistics charts without requiring external rangefinders or manual input. The system serves itself by computing the firing distance based on the relationship between initial angle of elevation and instantaneous angle of elevation, eliminating the need for separate distance measurement devices while maintaining precision.
4Adaptability or versatility
If multiple ballistics charts are to be used, then adaptability is improved, but device complexity increases
Solution Approach 1:
The computer-based aiming system can store and process multiple different ballistics charts within its memory, allowing it to adapt to various projectiles and firing conditions. The universal computer platform can switch between different ballistics charts based on the munition being fired, providing versatility without requiring separate dedicated systems for each chart type.
