Solution Overview

Problem

Existing carrying racks fail to provide optimal comfort and stability due to inadequate adjustment to the wearer's back shape and require additional frame constructions, leading to increased weight and complexity.

Innovation Solution

A carrying rack with a back plate shaped to conform to the human back in both vertical and horizontal directions, eliminating the need for a frame and incorporating a stiffening bead along the spine for enhanced stability and ventilation, with adjustable shoulder straps and a load node for versatile fit.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If a frame construction or vertical braces are used to provide structural stability, then the stiffness and stability of the carrying rack is improved, but the weight and device complexity increase

Engineering Contradiction:
ImprovestabilityVSAvoidweight
Core Design Contradiction:
Stability of the object's compositionVSWeight of moving object

Solution Approach 1:

The patent removes the frame construction and vertical braces from the carrying rack system. Instead of using separate structural elements for stiffening, the invention integrates the stiffening function directly into the back plate by shaping it with horizontal and vertical ridges, thereby eliminating unnecessary components and reducing weight while maintaining stability.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent combines the back plate and the stiffening structure into a single integrated component. The back plate itself is shaped with horizontal and vertical ridges that provide structural stiffening, merging the function of the back plate with the function of vertical braces, thereby eliminating the need for separate frame elements.

Inventive Principle:
Principle #5Merging (Combining)

2Stability of the object's composition

If a frame construction or vertical braces are used to provide structural stability, then the stiffness of the back plate is improved, but the device complexity increases

Engineering Contradiction:
ImprovestiffnessVSAvoidcomplexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The patent removes the frame construction and vertical braces from the carrying rack system. Instead of using separate structural elements for stiffening, the invention integrates the stiffening function directly into the back plate by shaping it with horizontal and vertical ridges, thereby eliminating unnecessary components and reducing weight while maintaining stability.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of operation

If padding of different thicknesses is used to adapt to the shape of the back, then the comfort is improved, but the manufacturing complexity and material usage increase

Engineering Contradiction:
ImprovecomfortVSAvoidmaterial usage
Core Design Contradiction:
Ease of operationVSQuantity of substance

Solution Approach 1:

The patent applies local quality by shaping the back plate with horizontal and vertical ridges that are strategically positioned to match the contours of the human back. This localized shaping provides comfort and load distribution without requiring thick padding materials throughout the entire back plate, thereby reducing overall material usage while maintaining comfort.

Inventive Principle:
Principle #3Local quality

4Stability of the object's composition

If the back plate is made rigid to provide stability, then the stiffness is improved, but the adaptability to different back shapes decreases

Engineering Contradiction:
ImprovestiffnessVSAvoidadaptability
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The patent applies local quality by shaping the back plate with horizontal and vertical ridges that are strategically positioned to match the contours of the human back. This localized shaping provides comfort and load distribution without requiring thick padding materials throughout the entire back plate, thereby reducing overall material usage while maintaining comfort.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent makes the back plate adaptable through its shaped ridges that can accommodate variations in back shapes. The horizontal and vertical ridges are designed to provide structural stability while the overall shaped configuration can adapt to different user anatomies, achieving both stiffness and adaptability.

Inventive Principle:
Principle #15Dynamics
