Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The patent replaces traditional mechanical sighting devices with a photoelectric sighting system that uses electronic sensors, processors, and display units to provide digital aiming assistance. This substitution enables beginners to achieve accurate shooting without relying on years of mechanical sighting experience, as the system electronically calculates and displays the correct aim point.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces an intermediary computational system that processes environmental parameters (temperature, humidity, wind, altitude) and calculates trajectory compensation. This intermediary layer bridges the gap between simple mechanical sighting and complex ballistics, providing automated aiming assistance that improves accuracy without requiring the user to manually perform complex calculations.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If traditional sighting devices are used, then the system is easy to operate, but the impact point and division center require multiple calibrations which produce unquantifiable deviation due to wear

Engineering Contradiction:
Improvesighting operationVSAvoidcalibration stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent replaces mechanical adjustment mechanisms with electronic calibration systems that use digital sensors and computational algorithms. This substitution eliminates the wear and tear associated with mechanical knobs and adjustment parts, ensuring that calibration parameters remain stable and quantifiable over time without degrading from physical wear.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent implements self-calibration functionality where the system automatically adjusts and maintains alignment between the impact point and division center using electronic sensors and feedback mechanisms. This self-service capability eliminates the need for frequent manual calibrations and prevents the accumulation of unquantifiable deviations that occur with repeated mechanical adjustments.

Inventive Principle:
Principle #25Self-service

3Measurement precision

If a large-sized complex photoelectric sighting system with multiple sensors is used, then environmental parameter measurement capability is improved, but the system complexity and sensor accessory requirements increase

Engineering Contradiction:

Solution Approach 1:

The patent merges multiple environmental sensing functions into an integrated photoelectric sighting system where temperature, humidity, wind, and altitude sensors are combined with the aiming mechanism. This merging reduces the need for separate sensor accessories and creates a unified system that collects and processes environmental data internally, improving measurement capability without proportionally increasing system complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent designs the photoelectric sighting system to perform multiple functions: it serves as both an aiming device and an environmental monitoring system. The same platform that provides ballistic calculation also measures temperature, humidity, wind, and altitude, eliminating the need for separate specialized sensors and reducing overall system complexity while maintaining comprehensive environmental parameter measurement capability.

Inventive Principle:
Principle #6Universality (Multi-functionality)
