Solution Overview

Problem

Existing projectile loaders face issues with external release mechanisms that are prone to damage, dirt accumulation, and accidental actuation, detracting from the sleek aesthetic desired by users, while also complicating access to internal components for maintenance and cleaning.

Innovation Solution

A projectile loader with a hinged body design that features an internal release mechanism, allowing the body to split into two portions for easy access without external protrusions, ensuring a streamlined appearance and protecting the mechanism from debris.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If external release mechanisms (push-buttons or latches) are used, then the loader can be opened for maintenance and cleaning, but the external appearance becomes less sleek and the mechanism is prone to damage, dirt, and accidental actuation

Engineering Contradiction:
Improveaccess to internal componentsVSAvoidexternal appearance
Core Design Contradiction:
Ease of operationVSShape

Solution Approach 1:

The release mechanism is extracted from the external surface and relocated to the interior of the loader body. The actuator is positioned inside the body, accessible through the projectile loading opening, while the release mechanism itself is hidden within the interior, eliminating external protrusions and maintaining a sleek appearance.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The release mechanism is nested within the interior space of the loader body. The actuator is positioned within the body cavity, and the release mechanism components are integrated into the internal structure, allowing the exterior surface to remain smooth and uninterrupted.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Ease of operation

If external release mechanisms are used, then the loader can be opened, but the mechanism is prone to damage and accidental actuation

Engineering Contradiction:
Improveopening capabilityVSAvoidmechanism durability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The release mechanism is extracted from the external environment and relocated to the protected interior space. This positioning shields the mechanism from external damage, dirt, and debris while preventing accidental actuation, as the actuator requires intentional access through the loading opening.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The internal positioning of the release mechanism provides preliminary protection against harmful external factors. The mechanism is pre-positioned within the protected interior space, preventing exposure to damage and accidental actuation before operation occurs.

Inventive Principle:
Principle #9Preliminary anti-action

3Device complexity

If the body is made as a single piece, then the structure is simpler, but access to internal components requires full disassembly

Engineering Contradiction:
Improvebody structureVSAvoidaccess to internal components
Core Design Contradiction:
Device complexityVSEase of repair

Solution Approach 1:

The loader body is segmented into a first portion and a second portion that can be separated relative to each other. The hinge connection allows the portions to be detached for maintenance and cleaning, providing easy access to internal components while maintaining a relatively simple overall structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The body portions are designed with dynamic separation capability through the hinge connection. The portions can be moved from a closed operational position to an open maintenance position, allowing flexible access to internal components while maintaining structural simplicity.

Inventive Principle:
Principle #15Dynamics

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Facilitates easy access to internal components while maintaining a sleek exterior, preventing accidental actuation and damage, and enhancing user experience by providing a convenient means to open and clean the loader without disassembly.

Implementation Method 1

The body is split into a first portion and a second portion, the first portion is attached to the second portion by a hinge, and the first portion and second portion are moveable relative to each other via the hinge between an open position and a closed position.
