Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing carrying devices for elongated objects, such as long-barreled weapons, are cumbersome, provide insufficient protection, and do not allow facile and stable carrying, especially in rugged terrain, leading to potential discomfort and safety risks during long walks or combat situations.

Innovation Solution

A rucksack frame integrated into the rucksack bag with transverse connecting members and frame extension elements forming U-shaped supports for the carrying pocket, allowing stable load transfer to the carrying system via adjustable straps, reducing bag deformation and providing secure, adjustable support for the elongated object.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the weapon is carried in a secondary bag with the nozzle pointing downwards and gunstock pointing upwards, then the weapon can be stored, but the user has to pull the weapon a substantial distance vertically up and out, which is cumbersome and may take several seconds

Engineering Contradiction:

Improveease of weapon removalVSAvoidtime to remove weapon

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The patent inverts the conventional vertical storage orientation by implementing a lateral carrying pocket where the weapon is accessed horizontally rather than vertically. The pocket is openable to a lateral exterior, allowing the user to pull the weapon horizontally out from the side of the rucksack bag, eliminating the need to pull it substantially vertically up and out.

Inventive Principle:

Principle #13The other way round (Inversion)

2Ease of operation

If the weapon is not fixed in relation to the pack to allow easy removal, then the weapon can be quickly accessed, but the carrying is not comfortable during long walks

Engineering Contradiction:

Improveease of weapon accessVSAvoidstability of weapon position

Core Design Contradiction:

Ease of operationVSStability of the object's composition

Solution Approach 1:

The patent implements a dynamic fixing system with releasable locking devices that can transition between locked and unlocked states. When locked, the weapon is securely fixed in the carrying pocket for stable carrying during long walks. When unlocked, the weapon can be easily accessed by opening the lateral pocket. This dynamic mechanism resolves the contradiction between ease of access and carrying comfort.

Inventive Principle:

Principle #15Dynamics

3Reliability

If a releasable locking device is used to secure the weapon, then the weapon can be fixed securely, but the device becomes more complex and cumbersome to use

Engineering Contradiction:

Improvesecurity of weapon fixationVSAvoidcomplexity of locking mechanism

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent employs a simple copying mechanism where the releasable locking device replicates common, intuitive locking actions (such as snap-fit or clip mechanisms) that users are already familiar with from everyday objects. This keeps the device complexity low while maintaining reliable security for weapon fixation.

Inventive Principle:

Principle #26Copying

4Stability of the object's composition

If the rucksack frame is integrated into the rucksack bag, then the structure is more stable, but the manufacturing becomes more complex

Engineering Contradiction:

Improvestability of rucksack structureVSAvoidease of rucksack assembly

Core Design Contradiction:

Stability of the object's compositionVSEase of manufacture

Solution Approach 1:

The patent segments the rucksack frame into modular components that can be separately manufactured and then assembled into the rucksack bag. This segmentation allows for stable integrated structure while maintaining ease of manufacture through modular assembly processes, reducing the complexity of creating a fully integrated frame as a single piece.

Inventive Principle:

Principle #1Segmentation

AI summary

A carrying device for an elongated object has a rucksack bag, a rucksack frame, a carrying system connected to the rucksack frame, and a carrying pocket at one side of the rucksack bag, openable to an lateral exterior of the rucksack bag and arranged to receive at least a portion of the elongated object to be carried. A rucksack frame is integrated in the rucksack bag, and has a first, upper transverse connecting member, and a first transverse frame extension element accommodated inside the rucksack bag and connected to the upper connecting member at a distance therefrom, forming at one lateral side of the rucksack bag a U-shaped upper support for the carrying pocket. The upper support is open to one side of the carrying pocket, and the first transverse frame extension element is extending in opposing directions, forming an upper support extending over a full width of the rucksack bag.
