Bow Magazine Segmentation for Consistent Projectile Contact Pressure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing magazines for weapons, particularly bow weapons, fail to provide consistent and adjustable contact pressure to projectiles, leading to uneven flight characteristics and reliability issues as the magazine nears depletion.
Innovation Solution
A magazine with a storage section and a separating mechanism that uses an actuation mechanism to separate and hold projectiles with a predefined force, independent of the number of projectiles, ensuring consistent contact pressure and improved flight characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a resilient member is used to provide contact pressure to projectiles in the storage space, then the projectiles are held in place, but the contact pressure becomes uneven and dependent on the amount of projectiles contained in the magazine
Solution Approach 1:
The magazine is divided into a storage section for multiple projectiles and a separate holding section for the single separated projectile. The separating mechanism segments the projectile supply process, ensuring that each projectile receives consistent contact pressure from the resilient member regardless of the total number of projectiles in the magazine.
Solution Approach 2:
The invention extracts the projectile separation function from the general storage function. By taking out one projectile at a time from the storage space to the holding section using the separating mechanism, the system ensures that the contact pressure applied to the active projectile is independent of the number of projectiles remaining in storage.
2Productivity
If projectiles are stored in a magazine for later use, then the weapon can fire multiple times without reloading, but the contact pressure on projectiles varies as the magazine nears depletion
Solution Approach 1:
The invention introduces dynamic adjustment capability through the separating mechanism. As projectiles are consumed from the storage section, the mechanism dynamically maintains proper contact pressure on the projectile in the holding section, ensuring consistent acceleration characteristics throughout the magazine's capacity cycle.
Solution Approach 2:
The holding section acts as an intermediary between the bulk storage and the firing mechanism. This intermediate stage ensures that the projectile receiving contact pressure is always in a controlled position, decoupling the pressure application from the varying number of projectiles in the storage section.
3Device complexity
If a simple storage space is used without a separating mechanism, then the device complexity is reduced, but the contact pressure cannot be consistently controlled
Solution Approach 1:
The magazine structure is segmented into distinct functional zones: a storage section for bulk projectile storage and a holding section for active projectile preparation. This segmentation adds minimal structural complexity while enabling consistent contact pressure control through the separating mechanism.
Solution Approach 2:
The separating mechanism is designed to automatically separate and position projectiles as they are consumed from the storage section. This self-service function maintains consistent contact pressure without requiring external intervention or complex control systems.
