Solution Overview

Problem

Existing rifle scopes face challenges in quick, precise, and easy adjustment of reticle and magnification settings, leading to potential errors due to complex mechanical operations and high costs, especially in low-light conditions.

Innovation Solution

An adjusting device with a rotatable adjusting cap and a fastening groove system that allows indicator elements to be slid along the circumference, providing a scalable and flexible solution for ballistic curve adjustments, featuring a dovetail or T-shaped geometry for precise guidance and secure positioning, with visual identifiers for easy differentiation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If conventional adjustment turrets with fine detent are used, then adjustment precision is improved, but adjustment speed and ease of operation deteriorate

Engineering Contradiction:
Improveadjustment precisionVSAvoidadjustment speed
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The adjustment device is divided into two independent functional components: an adjustment turret for precise reticle positioning and a separate magnification ring for zoom control. This segmentation allows each component to be optimized independently - the turret provides fine detent for precision while the ring provides smooth continuous adjustment for speed, eliminating the need to compromise between precision and speed in a single mechanism.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A independently rotatable magnification ring is introduced as an intermediary component between the user and the lens elements. This ring provides smooth continuous magnification adjustment without affecting the reticle position, while the separate adjustment turret maintains precise reticle positioning. The intermediary ring eliminates the need for complex coordinated adjustments, improving both speed and ease of operation.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If multiple adjustment operations are required independently, then adjustment functionality is improved, but device complexity increases

Engineering Contradiction:
Improveadjustment functionalityVSAvoidmechanical complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The adjustment system is segmented into two independent control mechanisms: a turret for reticle adjustment and a magnification ring for zoom control. Each mechanism operates independently with its own rotation and locking system, eliminating the need for complex interlinked mechanisms. This segmentation maintains full adjustment functionality while reducing overall mechanical complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The magnification ring serves multiple functions: it controls the variable magnification of the optical system and provides tactile feedback for adjustment confirmation. The turret simultaneously provides reticle position adjustment and ballistic curve selection through its indexed positions. This multi-functionality reduces the need for separate dedicated mechanisms, simplifying the overall device.

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

3Productivity

If precise and rapid adjustment changes are implemented, then operational efficiency is improved, but mechanical complexity increases

Engineering Contradiction:
Improveoperational efficiencyVSAvoidmechanical complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

By separating reticle adjustment and magnification control into independent mechanisms, each can be optimized for its specific function. The turret provides rapid indexed positions for different ballistic curves without requiring complex calculations, while the magnification ring provides smooth continuous adjustment. This segmentation enables precise and rapid adjustments without increasing overall mechanical complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The turret is pre-indexed with positions corresponding to different ballistic curves and adjustment values. Users can directly select the required adjustment position without performing calculations or multiple adjustment steps. This preliminary preparation of adjustment positions significantly improves operational efficiency while keeping the mechanical structure simple.

Inventive Principle:
Principle #10Preliminary action
