Backpack Waist Bag Rotation Mechanism

Solution Overview

Problem

Conventional backpacks do not allow for easy deployment of a waist bag to the front of the user while the backpack is worn on the back, limiting access to the waist bag's contents without removing the backpack.

Innovation Solution

A backpack design with side openings that enable the waist bag receiver to be rotated from the lower compartment to the front, secured by a door mechanism, allowing the waist bag to be accessed without removing the backpack, using friction and buckle systems for secure containment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the waist bag receiver is stored in the lower compartment of the backpack, then the backpack maintains a conventional appearance with waist belt, but the user cannot easily access the waist bag contents without removing the backpack

Engineering Contradiction:

ImproveAccess to waist bag contentsVSAvoidBackpack structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The waist bag receiver is nested within the lower compartment of the backpack, allowing it to be stored inside the backpack structure when not in use. This nesting arrangement enables the backpack to maintain its conventional appearance while housing the waist bag receiver, and allows easy deployment by rotating the receiver through the side opening without removing the backpack.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The waist bag receiver is designed to be dynamically deployable through side openings in the backpack. The receiver can be rotated from the lower compartment to the front of the user and back again, providing dynamic access to waist bag contents while maintaining the backpack's conventional appearance when the receiver is stowed.

Inventive Principle:

Principle #15Dynamics

2Ease of operation

If side openings are added to the backpack for waist bag deployment, then easy access to waist bag is enabled, but the backpack appearance is altered

Engineering Contradiction:

ImproveWaist bag deploymentVSAvoidBackpack appearance

Core Design Contradiction:

Ease of operationVSShape

Solution Approach 1:

The waist bag receiver is nested within the lower compartment of the backpack, allowing it to be stored inside the backpack structure when not in use. This nesting arrangement enables the backpack to maintain its conventional appearance while housing the waist bag receiver, and allows easy deployment by rotating the receiver through the side opening without removing the backpack.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The side openings are strategically positioned and sized to allow waist bag receiver deployment while minimizing visual impact on the overall backpack appearance. The openings are located in the lower portion of the backpack where they are less conspicuous, and the receiver can be stowed within the lower compartment to restore the backpack's conventional appearance when not in use.

Inventive Principle:

Principle #3Local quality

3Productivity

If the waist bag receiver is made easily rotatable, then quick access is achieved, but secure containment within the compartment is compromised

Engineering Contradiction:

ImproveSpeed of accessVSAvoidSecure containment

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The waist bag receiver is designed to be dynamically deployable through side openings in the backpack. The receiver can be rotated from the lower compartment to the front of the user and back again, providing dynamic access to waist bag contents while maintaining the backpack's conventional appearance when the receiver is stowed.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The receiver is pre-positioned within the lower compartment in a secure stowed position. When access is needed, the user simply rotates the receiver through the side opening to the front position. The preliminary secure containment in the lower compartment ensures the receiver is ready for quick deployment without requiring additional securing actions.

Inventive Principle:

Principle #10Preliminary action

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

AI summary

The invention provides improved backpack and waist bag carrying systems in which a waist bag rotates through a lower compartment of a backpack to allow the bearer of the backpack to access the contents of the receiver of the waist bag by rotating the waist bag to the front of the bearer's torso. One or more doors are provided in one aspect to secure the receiver of the waist bag in the lower compartment of the backpack but permit the egress of the receiver through the opening covered by the door, which may be tensioned away from the opening by a tensioning element when the free end of the door is released.
