Solution Overview

Problem

Existing backpack designs lack flexibility in terms of color, shape, and size options, requiring a new backpack when changes in use or preference are desired, as the main body and shoulder strap are unified.

Innovation Solution

A backpack design featuring a box-shaped storage compartment with removable back plates and shoulder straps, utilizing convex elements and insertion holes for easy attachment and detachment, allowing for various combinations of storage compartments and back plates to be selected and exchanged.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the main body and shoulder strap are unified in a single backpack design, then the structure is simple and easy to manufacture, but the user cannot change color, shape or size according to use or preference

Engineering Contradiction:
Improveability to change color, shape or sizeVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The backpack is divided into separate modules: a main body portion and a shoulder strap portion that can be detached from each other. This segmentation allows users to mix and match different components to change the appearance and functionality of the backpack without increasing overall structural complexity, as each module maintains a simple design suitable for manufacturing.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If the storage compartment and back plate are made as a unified structure, then the manufacturing process is simpler, but the user cannot optionally select different combinations of storage compartments and back plates

Engineering Contradiction:
Improveoptional selection of combinationsVSAvoidmanufacturing process complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The storage compartment and back plate are designed as separable components connected through a fastening mechanism. This allows the backpack to be manufactured in modular units that can be independently produced and then assembled in various combinations, enabling optional selection without requiring complex integrated manufacturing processes.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The back plate is designed with universal compatibility features that allow it to work with multiple different storage compartment configurations. The standardized connection interface enables a single back plate to support various storage compartment types, sizes and colors, providing multi-functionality while maintaining simple manufacturing for each component.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If the backpack components are designed to be removable and exchangeable, then the user can select from multiple combinations, but the attachment and detachment mechanism becomes more complex

Engineering Contradiction:
Improveexchangeability of componentsVSAvoidattachment mechanism complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The fastening mechanism is designed as a discrete, extractable component system with convex elements on one part and corresponding insertion holes on the other. This extraction-based design allows for simple attachment and detachment operations while maintaining structural integrity, avoiding the need for complex locking mechanisms or multiple fastening points.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

The backpack encompasses a box-shaped storage-compartment having first and second main surfaces opposite to each other and a triple-sided surface whereby triple continuous sides of the first main surface and triple sides of the second main surface opposite thereto are connected to each other, and a back plate encompassing a joint plane opposite to the first main surface and a backrest plane opposite to the joint plane. A convex element is disposed on one of the first main surface or the joint plane, and an insertion hole with a structure matching the convex element is disposed on a position on the other of the first main surface or the joint plane corresponding to the convex element. The storage-compartment and the back plate can be freely attached to and detached from each other by placing the convex element into the insertion hole and separating the convex element from the insertion hole.
