Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical sights for small arms shooting lack convenience due to the inability to provide both small and large target images simultaneously, resulting in complex designs, high costs, and low reliability.
Innovation Solution
The optical sight features two parallel optical channels with different magnifications, sharing a common eyepiece and objectives with equal focal lengths, and an optical element positioned in front of the focal plane to shift the higher-magnification channel's axis, allowing simultaneous observation of both images without altering the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a complicated design solution is used to provide both large and small target images, then the functional capability is improved, but the cost increases and reliability decreases
Solution Approach 1:
The patent combines two optical channels with different magnifications into a single integrated sight device that shares common components (objective lens, erecting system, eyepiece). This merging approach provides both large and small target images simultaneously while reducing the number of separate devices needed, thereby improving reliability through shared components and reducing overall system complexity.
Solution Approach 2:
The optical sight is designed with multi-functionality to serve multiple purposes: it can display both low-magnification and high-magnification images simultaneously, allowing the user to survey large fields of view and examine central details without switching between different devices. The common optical components serve both channels, enhancing versatility while maintaining reliability.
2Adaptability or versatility
If a complicated design solution is used to provide both large and small target images, then the functional capability is improved, but the cost increases
Solution Approach 1:
The patent merges two optical channels into a single integrated structure that shares common components including the objective lens, erecting system, and eyepiece. This combining approach reduces the total number of components that need to be manufactured and assembled, thereby lowering production costs while maintaining the functional capability to provide both large and small target images.
Solution Approach 2:
The optical sight employs universal components that serve multiple functions within the system. The common objective lens and erecting system are used by both magnification channels, reducing the need for separate components for each function. This multi-functionality approach simplifies manufacturing processes and reduces overall production costs while maintaining versatility.
3Adaptability or versatility
If separate optical devices are used for different magnifications, then the observation capability is improved, but the device complexity increases
Solution Approach 1:
The patent combines two separate optical channels with different magnifications into a single integrated sight device. By merging the channels and sharing common components (objective lens, erecting system, eyepiece), the design reduces overall complexity compared to using separate devices, while maintaining the observation capability to view both large and small targets simultaneously.
Solution Approach 2:
The optical sight is segmented into two parallel optical channels that operate independently but share common components. Each channel is optimized for a specific magnification level, allowing simultaneous observation of different target sizes. This segmentation approach maintains observation versatility while reducing device complexity through component sharing.
