Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional riflescopes with smaller main tube diameters face challenges in providing optimal optical performance due to limited adjustment ranges and angles, which affect accuracy and range capabilities.
Innovation Solution
Incorporating a pivotable system erector that moves along a path longer than the main tube internal diameter, with a chamber design allowing greater movement and specific geometric configurations such as tapered sections and cavities, to enhance optical performance and adjustment capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a smaller main tube diameter is used, then the device becomes more compact, but the adjustment range and optical performance are limited
Solution Approach 1:
The patent extends the adjustment path from a conventional linear movement within the tube diameter to a curved arc path that utilizes the longitudinal dimension of the tube. The erector assembly moves along an arc trajectory defined by the pivot point, allowing the adjustment range to exceed the main tube internal diameter by utilizing the third dimension (length of the tube) rather than being constrained to two-dimensional lateral movement.
Solution Approach 2:
The system transitions from a static erector position to a dynamic pivotable erector that can rotate about a pivot point. This dynamic mechanism allows the erector to sweep through an arc path, converting rotational movement into extended linear adjustment range, thereby overcoming the physical constraints of the tube diameter.
2Volume of moving object
If a smaller main tube diameter is used, then the device becomes more compact, but the range capabilities are reduced
Solution Approach 1:
The adjustment path is extended by utilizing the longitudinal dimension of the tube through arc-shaped movement. Instead of being limited to lateral displacement within the tube diameter, the erector traverses an arc path that can extend beyond the tube's internal diameter by leveraging the tube's length and the pivot point's strategic positioning.
Solution Approach 2:
The pivot point acts as an intermediary mechanism that transforms limited lateral space into extended adjustment range. By pivoting about this intermediate point, the erector assembly can achieve a longer effective adjustment path than would be possible through direct linear movement within the constrained tube diameter.
3Device complexity
If conventional erector movement is used, then the structure is simple, but the adjustment precision and range are limited
Solution Approach 1:
The erector mechanism is made dynamic and pivotable rather than fixed or linearly movable. This allows for greater adjustment precision through controlled rotational movement about the pivot point, enabling fine-tuned angular adjustments that translate to improved aiming accuracy while maintaining a relatively simple overall structure.
Solution Approach 2:
The adjustment path is configured as an arc rather than a straight line, allowing the erector to move along a curved trajectory. This curved path provides more precise angular control and enables the system to achieve greater adjustment range and precision without significantly increasing structural complexity.
