Rotating Inner-Tube Zoom Scope Without Body Weakening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing zoom sights suffer from structural weakness at the zoom groove, leading to deformation or breakage upon impact, which reduces their service life.
Innovation Solution
A zoom sight design that eliminates the zoom pin and groove, enabling synchronous circumferential rotation of the eyepiece set, drive member, and inner tube, allowing for easy adjustment of the zoom ratio without compromising structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a zoom groove is formed in the sight body to enable zoom function, then the zoom ratio can be adjusted, but the local strength of the sight body is weakened making it prone to deformation or breakage upon impact
Solution Approach 1:
The patent removes the zoom groove from the sight body structure. Instead of having a groove in the sight body, the zoom function is achieved through a separate inner tube that rotates independently. This extraction of the harmful groove element eliminates the structural weakness while preserving the zoom capability through an alternative mechanical arrangement.
Solution Approach 2:
The patent divides the zoom mechanism into separate components: an inner tube that can rotate independently from the sight body, and a zoom lens set that moves within the inner tube. This segmentation allows the zoom function to be achieved without compromising the structural integrity of the sight body, as the loading and rotation are isolated to the inner tube rather than being distributed through the sight body.
2Adaptability or versatility
If a zoom pin and zoom groove are used to drive the inner tube rotation, then the zoom function is achieved, but the structure becomes more complex and the sight body is more vulnerable to impact damage
Solution Approach 1:
The patent removes the zoom pin and zoom groove assembly from the structure. The inner tube is provided with a rotation driving structure that eliminates the need for these separate components. By extracting these elements, the design achieves the same zoom function with fewer parts and reduced structural complexity.
Solution Approach 2:
The patent merges the rotation driving function directly into the inner tube structure itself, eliminating the need for separate zoom pins and grooves. The inner tube's wall is provided with a structure that directly enables rotation and zoom control, combining multiple functions into a single integrated component rather than using separate discrete elements.
3Adaptability or versatility
If the sight body has a zoom groove, then zoom adjustment is enabled, but the service life is reduced due to increased susceptibility to deformation and breakage
Solution Approach 1:
The patent removes the zoom groove from the sight body, eliminating the structural weakness that led to deformation and breakage. By extracting this harmful feature, the sight body's structural integrity is preserved, directly improving reliability and service life while maintaining zoom functionality through the independent inner tube rotation mechanism.
Solution Approach 2:
The patent segments the zoom mechanism from the sight body structure by using an independent inner tube that rotates separately. This segmentation isolates the mechanical stresses and impacts to the inner tube rather than transmitting them through the sight body, thereby protecting the sight body from deformation and breakage and extending its service life.

AI summary
The present application relates to the field of sights, and provides a zoom sight. The zoom sight includes a sight body, an inner tube, a zoom lens set, an eyepiece set, and a drive member. The inner tube is provided in the sight body, and capable of making circumferential rotation around a central axis of the inner tube; an axial position of the inner tube relative to the sight body is stable; the zoom lens set is provided in the inner tube, and linked with the inner tube; the inner tube in the circumferential rotation drives the zoom lens set to move along an axial direction of the inner tube; the eyepiece set is provided at an end of the sight body close to an eye side; the drive member is connected between the inner tube and the eyepiece set; and the drive member, the eyepiece set, and the inner tube maintain synchronous circumferential rotation. According to the zoom sight, the eyepiece set can be rotated circumferentially to drive the drive member and the inner tube to make synchronous circumferential rotation, thereby driving the zoom lens set to move along the axial direction of the inner tube, and realizing a zoom operation. The zoom sight can remove such structures as a zoom pin, and a zoom groove on the sight body, thereby ensuring a structural strength of the sight body, lowering a risk of deformation and breakage of the sight body, and ensuring a service life of the zoom sight.
