Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing telescopic-sight mounting systems for hunting weapons face challenges in reproducible mounting precision, as slight changes in alignment can significantly affect the accuracy of the reticule's aim, leading to inaccuracies in projectile placement.
Innovation Solution
The telescopic-sight mounting system incorporates a swivel joint and a locking interface with a sliding surface and a running surface, where the sliding surface is designed to be larger than the running surface, and the contact region is optimized to reduce friction and allow for improved reproducibility, including curvature and a steep sliding angle to enhance locking stability and tolerance for angle deviations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a traditional locking interface with large contact area is used, then locking strength is improved, but friction increases and reproducibility deteriorates
Solution Approach 1:
The patent applies local quality by concentrating the locking function in a specific localized contact region rather than distributing it over a large area. The contact region is precisely defined where the sliding surface meets the running surface, creating a focused locking mechanism that maintains strength while minimizing friction's impact on precision.
Solution Approach 2:
The patent changes the geometric parameters of the locking interface by introducing a steep sliding angle (greater than 45 degrees) and optimizing the contact region dimensions. This parameter optimization reduces the effective friction area while maintaining locking force, thereby improving reproducibility without sacrificing strength.
2Stability of the object's composition
If the sliding surface is made larger to increase contact area, then locking stability is improved, but friction increases and reproducibility deteriorates
Solution Approach 1:
The patent employs curvature by designing the sliding surface and running surface with optimized geometric shapes. The contact region is defined with specific curvature characteristics that allow for stable locking while minimizing the actual friction-generating area, thus maintaining reproducibility.
Solution Approach 2:
The patent optimizes parameters including the sliding angle (greater than 45 degrees) and the dimensional relationship between sliding surface and running surface. This parameter tuning creates a stable locking mechanism that is less sensitive to friction variations, improving reproducibility.
3Reliability
If the contact region is enlarged to improve locking reliability, then locking reliability is improved, but friction increases and reproducibility deteriorates
Solution Approach 1:
The patent applies local quality by precisely defining the contact region as a specific localized area where the sliding surface meets the running surface. This focused contact approach ensures reliable locking at the critical interface while minimizing the overall friction area that could affect reproducibility.
Solution Approach 2:
The patent optimizes the contact region parameters including its area, shape, and position relative to the sliding surface. By carefully controlling these parameters, the patent achieves reliable locking without excessive friction that would compromise reproducibility.
