Solution Overview

Problem

Sighting scopes face challenges in achieving compatibility between high precision and high shock resistance, with existing angular adjustment mechanisms either compromising on precision due to size and cost considerations or suffering from optical misalignment and exposure to environmental factors.

Innovation Solution

A sighting scope design featuring a rotational support structure with spherical sliding contact portions that rotatably support the scope body around a spherical center, allowing for precise adjustment of the inclined angle while maintaining robustness against shocks and environmental interference.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a high precision angular adjustment mechanism is used, then adjusting precision is improved, but shock resistance deteriorates

Engineering Contradiction:
Improveadjusting precisionVSAvoidshock resistance
Core Design Contradiction:
Measurement precisionVSReliability

Solution Approach 1:

The patent employs a spherical support structure where the scope body rotates around a spherical center. The spherical sliding contact portions enable smooth rotational movement while distributing mechanical stresses uniformly across the spherical surface. This curvature-based design maintains high adjusting precision through controlled rotation while inherently providing shock resistance by absorbing impact forces through the spherical geometry rather than concentrating them on precise adjustment components.

Inventive Principle:
Principle #14Spheroidality (Curvature)

2Ease of operation

If the angular adjustment mechanism is exposed on the outside for easy adjustment, then ease of operation is improved, but reliability deteriorates due to fire dust entry

Engineering Contradiction:
Improveadjustment accessibilityVSAvoidprotection from environmental factors
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent integrates the angular adjustment mechanism within the nested structure of the outer frame and scope body. The adjustment mechanism is positioned inside the protected cavity formed by the outer frame, which shields it from fire dust and environmental contaminants. Despite this enclosed positioning, the mechanism remains accessible through the design of the outer frame that allows operational access while maintaining protective enclosure, thus achieving both ease of operation and reliability.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Adaptability or versatility

If the inner tube is excessively inclined to adjust landing point, then adaptability is improved, but optical performance deteriorates due to misalignment

Engineering Contradiction:
Improvelanding point adjustment rangeVSAvoidoptical alignment precision
Core Design Contradiction:
Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The spherical support structure enables the scope body to incline and rotate around a spherical center, providing a wide range of adjustable landing points. The spherical geometry ensures that during inclination, the optical axis of the inner tube remains properly aligned with the optical axis of the scope body by rotating around a centered spherical pivot point. This prevents misalignment that would occur with simple hinge-based inclination, thus maintaining optical performance while achieving broad adaptability for various shooting scenarios.

Inventive Principle:
Principle #14Spheroidality (Curvature)

AI summary

A sighting scope 1 includes; a scope body 2; an outer frame 3 covering at least a middle portion along an optical axis of the scope body; a rotational support structure which rotatably support the scope body 2 around a rotational axis located on a plane orthogonal to the optical axis in the outer frame; a rotational sliding contact portion which is placed between the scope body and one of opening edges at ends of the outer frame located on front and back sides of the rotational axis along the optical axis, and which is designed to be able to slide around the rotational axis; and an angular adjustment mechanism which can adjust an inclined angle of the scope body with respect to the outer frame.
