Solution Overview

Problem

Conventional backpacks distribute weight unevenly on the back, leading to muscle fatigue and discomfort due to their design, which can cause cramping and tension in the back muscles.

Innovation Solution

An ergonomic backpack design featuring a wider top compartment, strategically shaped frame with massage beads that complement the spine, and adjustable neck support to distribute weight higher on the back and provide massage functions, reducing muscle fatigue.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional backpack design is used, then simple structure is maintained, but weight distribution is unhealthy and causes muscle fatigue

Engineering Contradiction:

Improveweight distributionVSAvoidbackpack structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The backpack is divided into multiple functional components: a rigid frame structure segmented into vertical and horizontal members, separate cushioning elements, and adjustable straps. This segmentation allows each component to be optimized for its specific function while collectively providing healthy weight distribution.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The frame members are designed with curved surfaces that conform to the natural curvature of the human back. The vertical members have a convex surface facing the back, and the horizontal members have a concave surface, creating ergonomic contact points that distribute weight evenly across the back muscles.

Inventive Principle:

Principle #14Spheroidality (Curvature)

2Ease of operation

If conventional backpack design is used, then manufacturing is simple, but causes muscle cramping and discomfort

Engineering Contradiction:

ImprovecomfortVSAvoidmanufacturing complexity

Core Design Contradiction:

Ease of operationVSEase of manufacture

Solution Approach 1:

The backpack combines multiple materials with different properties: rigid materials for the frame structure to provide support, cushioning materials (such as foam or padded fabric) for comfort, and flexible materials for the straps and covering. This composite approach addresses both comfort and structural requirements.

Inventive Principle:

Principle #40Composite materials

3Ease of operation

If weight is distributed lower on the back, then cargo compartment capacity is maximized, but causes fatigue in lower back muscles

Engineering Contradiction:

Improveweight distributionVSAvoidwearable duration

Core Design Contradiction:

Ease of operationVSDuration of action of moving object

Solution Approach 1:

The frame structure is designed to counterbalance the weight of the cargo compartment and its contents by providing rigid support beams that distribute the load away from the lower back. The horizontal members act as counterweights to offset the downward force of the cargo, reducing strain on lower back muscles.

Inventive Principle:

Principle #8Anti-weight (Counterweight)

AI summary

An embodiment of the present invention provides a backpack for wearing on a back of a user. The backpack includes at least one cargo compartment, two straps, and a frame. The cargo compartment is wider at a top end of the cargo compartment than at the bottom end. The frame has a first portion located adjacent to one side of the user's spine and a second portion located adjacent to the other side of the user's spine. The first and second portions are shaped to be complementary to the user's spine. Also, massaging beads are located in the frame and massage muscles on each side of the user's spine.
