Solution Overview

Problem

Conventional telescopic target acquisition devices are ineffective at long ranges due to limitations in accurately compensating for bullet drop and windage effects, and they often fail to provide quick and reliable target acquisition, especially when dealing with targets of varying sizes.

Innovation Solution

The development of reticles with secondary aiming points and markings that allow shooters to accurately determine range and make adjustments for projectile drop and windage without needing to move adjustment knobs, enabling precise targeting at any range using the shooter's knowledge and experience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If conventional telescopic target acquisition devices with central cross-hairs are used, then the device structure remains simple, but the ability to accurately compensate for bullet drop and windage at long ranges deteriorates

Engineering Contradiction:

Improvetargeting accuracyVSAvoidreticle structure complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The reticle is divided into multiple functional zones: central cross-hairs for primary aiming, secondary horizontal cross-hairs for bullet drop compensation, and vertical hash-marks for windage adjustments. Each segment serves a specific ballistic correction function, allowing precise long-range targeting without requiring complex mechanical adjustment mechanisms.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The reticle is pre-calibrated with secondary aiming points and hash-marks positioned at specific intervals corresponding to known bullet drop and windage values. Shooters select appropriate aiming points based on pre-determined range and environmental conditions, eliminating the need for real-time mechanical adjustments during firing.

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If adjustment knobs are provided for bullet drop and windage compensation, then the device can be adjusted for different conditions, but the operation becomes more complex and time-consuming

Engineering Contradiction:

Improveadjustability for different conditionsVSAvoidspeed of target acquisition

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The mechanical adjustment knob system is replaced with an optical reticle system where ballistic corrections are encoded in the reticle's geometry. Secondary horizontal cross-hairs and vertical hash-marks provide pre-calculated correction points, allowing shooters to make corrections by simply changing their aiming point selection rather than mechanically adjusting the entire scope.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

All necessary adjustment values are pre-calculated and encoded into the reticle's marking positions during manufacturing. Shooters only need to select the appropriate pre-marked aiming point based on range and conditions, eliminating time-consuming mechanical adjustments and enabling rapid target acquisition.

Inventive Principle:

Principle #10Preliminary action

3Productivity

If conventional central cross-hair aiming is used, then the reticle design remains simple, but the speed of target acquisition deteriorates at long ranges

Engineering Contradiction:

Improvetarget acquisition speedVSAvoidaiming point precision

Core Design Contradiction:

ProductivityVSMeasurement precision

Solution Approach 1:

The reticle provides multiple discrete aiming point options (central cross-hair, secondary horizontal cross-hairs, and vertical hash-marks) each optimized for specific range and target conditions. Shooters can rapidly select the appropriate aiming point based on pre-determined range, eliminating the need for slow mechanical adjustments while maintaining precise aiming capability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The reticle enables dynamic aiming point selection where shooters can quickly transition between different aiming points (central or secondary) based on changing target conditions, range, and environmental factors. This dynamic selection capability maintains both speed and precision without requiring mechanical scope adjustments.

Inventive Principle:

Principle #15Dynamics

4Adaptability or versatility

If multiple secondary aiming points are added to the reticle, then the ability to target at various ranges improves, but the reticle complexity increases

Engineering Contradiction:

Improverange coverage capabilityVSAvoidreticle marking complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The reticle is segmented into distinct functional zones: central cross-hairs for close-range aiming, secondary horizontal cross-hairs for medium-range bullet drop compensation, and vertical hash-marks for windage adjustments. Each segment serves a specific range or correction function, providing comprehensive range coverage through organized functional segmentation rather than random complexity.
