Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional telescopic sights, such as riflescopes, lack adaptability in low light conditions and are limited by fixed optical power settings and aiming marks, which cannot be adjusted for varying shooting distances, wind conditions, or other external factors, and are dependent on electronic functions that may fail.
Innovation Solution
A riflescope design featuring a detachable digital ocular group with a photo-sensor, processor, and digital display that allows for adjustable optical properties, secondary aiming marks, and calibration using invisible markers, enabling use in low light conditions and without power, and accommodating different shooting scenarios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed optical power setting is used in a telescopic sight, then the device structure is simple, but the adaptability to different shooting distances and conditions is limited
Solution Approach 1:
The patent implements a variable power zoom mechanism that allows the optical magnification to be dynamically adjusted by the user. The objective group and ocular group are designed to accommodate zoom lenses that can change focal length, enabling adaptation to different shooting distances without requiring multiple fixed-power scopes. This dynamic adjustment capability directly resolves the contradiction by providing versatility while maintaining a unified optical system structure.
Solution Approach 2:
The telescopic sight is designed with a universal mounting interface and adjustable optical system that can serve multiple shooting scenarios. The scope can be mounted on various firearm platforms and configured for different ranges and conditions through its variable power capability and adjustable reticle systems, making it a multi-functional device that replaces what would traditionally require multiple specialized scopes.
2Adaptability or versatility
If a single aiming mark is provided in the telescopic sight, then the reticle structure is simple, but the adaptability to different shooting scenarios and external factors is limited
Solution Approach 1:
The reticle system incorporates adjustable aiming marks that can be repositioned or replaced based on shooting conditions. The patent describes reticle systems where the position and configuration of aiming marks can be changed to account for different distances, wind conditions, and external factors. This dynamic reticle configuration allows shooters to adapt to various scenarios without changing the entire scope.
Solution Approach 2:
The reticle is divided into multiple discrete aiming marks or reference points that can be independently adjusted or activated. This segmentation allows the shooter to use different portions of the reticle for different shooting scenarios, such as using holdover marks for long-range shooting or windage adjustments for lateral corrections, providing versatility while maintaining a relatively simple overall reticle structure.
3Adaptability or versatility
If electronic functions are integrated into the telescopic sight, then the adaptability and functionality are enhanced, but the reliability in case of power failure or electronic defect is reduced
Solution Approach 1:
The patent incorporates an intermediary optical system that can function independently of electronic components. The basic telescopic sight with objective group, ocular group, and reticle provides a reliable optical foundation that works without power. Electronic enhancements such as illuminated reticles or digital displays serve as optional intermediaries that can be added or removed without compromising the core optical functionality, thus maintaining reliability while enabling enhanced adaptability when needed.
Solution Approach 2:
The scope is designed with redundant optical paths and mechanical backup systems that ensure functionality even if electronic components fail. The illumination system, for example, may include both battery-powered LED illumination and passive reflective reticle options, so that if the electronic illumination fails, the shooter still has the mechanical reticle visible through the optical system. This prior cushioning approach ensures reliability while allowing electronic enhancements for improved adaptability.
4Illumination intensity
If night vision instruments are connected to the telescopic sight, then the ability to view in low light conditions is improved, but the device complexity and loss of substance are increased
Solution Approach 1:
The telescopic sight is designed with a universal mounting system and optical interface that can accommodate various night vision devices. The objective group and ocular group are configured to work with both standalone and attached night vision instruments, allowing the same base scope to serve as a day scope, night scope, or both depending on attachments. This multi-functionality reduces overall system complexity by using a single versatile platform rather than requiring separate dedicated scopes for day and night use.

AI summary
A riflescope is provided with a detachable digital ocular lens group that enables vision enhancement functions, e.g. night vision, zoom, etc while being replaceable with a regular ocular group in the event of power failure or faulty components. To ensure accuracy of the digital ocular lens group, a non-visible marker, e.g. IR marker, may be placed on a reticle that can be detected by a photo-sensor of the digital ocular. A processor can use the detected position of the marker to calibrate the digital display of the digital ocular.
