Solution Overview

Problem

Existing projectile loaders for guns, such as paintball guns, have limitations in handling high capacities and accommodating different shaped projectiles without applying stress or tension, leading to inefficiencies in loading and storage.

Innovation Solution

A high capacity loader design featuring an outer housing with rotating drive cores, an indexing assembly, and a magazine that maintains projectiles in a defined load path, allowing for sequential loading and accommodating various shapes without compression or tension, using a spring-loaded drive assembly and ratchet mechanism for efficient operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If a high capacity loader design is used to accommodate multiple projectiles, then the storage capacity increases, but the complexity of the device increases

Engineering Contradiction:
Improvestorage capacityVSAvoiddevice complexity
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The loader is divided into multiple drive cores (first drive core and second drive core) that operate independently but are rotationally connected. Each drive core has its own indexing assembly, allowing the system to handle large capacities through modular, segmented operation rather than a single complex mechanism

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The second drive core is positioned within the outer housing that contains the first drive core, creating a nested arrangement. The indexing assembly and drive assembly are integrated within the same structural framework, allowing multiple functional elements to occupy shared space efficiently

Inventive Principle:
Principle #7Nested doll (Nesting)

2Reliability

If projectiles are retained in a defined load path around rotating drive cores, then the reliability of sequential loading improves, but the device complexity increases

Engineering Contradiction:
Improveloading reliabilityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The indexing assembly acts as an intermediary mechanism between the drive assembly and the drive cores. It controls the rotational movement of the drive cores in discrete, precise increments, ensuring reliable sequential loading without requiring direct complex control of each drive core's rotation

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The drive cores rotate on drive shafts that are rotationally connected, allowing the first drive core's rotation to automatically drive the second drive core. This self-servicing mechanism reduces the need for additional complex control systems while maintaining synchronized operation

Inventive Principle:
Principle #25Self-service

3Ease of operation

If a spring-loaded drive assembly is used to provide rotational force, then the ease of operation improves, but the device complexity increases

Engineering Contradiction:
Improveease of operationVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The spring-loaded drive assembly provides periodic rotational impulses to the drive cores through the indexing mechanism. The indexing assembly allows the spring to engage and disengage in regular cycles, converting continuous spring pressure into discrete, controlled rotational movements that are easy to operate

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The spring-loaded mechanism replaces more complex motorized or manually-cranked drive systems. The elastic potential energy storage in the spring provides a simple, reliable source of rotational force that can be easily loaded and discharged without complex control systems

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

AI summary

A high capacity loader for sequentially loading a plurality of projectiles into a launcher. The loader has a first drive core, a second drive core and a load path to maintain the projectiles in a defined path around the first and second drive cores. The second drive core is rotationally connected to the first drive core. An indexing assembly is provided to index the drive cores. A drive assembly provides a rotational force for the drive cores. A magazine extends from the housing to connect the loader to the launcher and to load the projectiles into the launcher. The projectiles are individually indexed on the first and second drive cores and are free from force by adjacent projectiles.
