Solution Overview

Problem

Existing umbrellas and backpacks fail to integrate aesthetics and practicality, particularly in combining medieval or fantasy themes, and do not effectively address moisture-related issues such as odor and water buildup during storage.

Innovation Solution

A decorative umbrella and backpack device that integrates a sword-themed umbrella with a shield-themed backpack, featuring a retractable sheath for water drainage and a drainage plug in the backpack to manage moisture, while maintaining an appealing aesthetic.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the umbrella is stored inside the backpack, then the umbrella is protected and convenient to carry, but moisture buildup causes odors and mold formation

Engineering Contradiction:

Improveconvenience of carryingVSAvoidmoisture buildup, odors, mold

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The backpack is divided into separate compartments: a main storage compartment and a dedicated umbrella storage compartment with drainage functionality. This segmentation allows the umbrella to be stored separately from other items while providing specialized moisture management.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A drainage plug acts as an intermediary component in the umbrella storage compartment, providing a controlled pathway for excess water to escape. This mediator component solves the moisture buildup problem without requiring the umbrella to be completely dry before storage.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Shape

If the umbrella handle is designed to resemble a sword hilt, then the aesthetic appeal is enhanced, but the structural complexity increases

Engineering Contradiction:

Improveaesthetic appearanceVSAvoidstructural complexity

Core Design Contradiction:

ShapeVSDevice complexity

Solution Approach 1:

The umbrella handle is designed as a visual copy or representation of a sword hilt rather than an actual sword component. This copying approach achieves the desired aesthetic appeal while maintaining the functional simplicity of a standard umbrella handle structure.

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The handle is adorned with decorative indicia that mimic metal textures and patterns through visual means rather than actual metal construction. This allows the sword-like appearance to be achieved through surface design rather than structural complexity.

Inventive Principle:

Principle #32Color changes

3Shape

If the backpack is designed to resemble a shield, then the thematic consistency is improved, but the manufacturing complexity increases

Engineering Contradiction:

Improvethematic consistencyVSAvoidmanufacturing complexity

Core Design Contradiction:

ShapeVSEase of manufacture

Solution Approach 1:

The backpack exterior is constructed using flexible materials that can be molded into shield-like shapes without requiring complex rigid frameworks. This allows the thematic shield design to be achieved through material flexibility rather than complex manufacturing processes.

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The backpack combines different materials with complementary properties to achieve both the shield aesthetic and functional requirements. This composite approach allows for a streamlined manufacturing process while maintaining the desired thematic appearance.

Inventive Principle:

Principle #40Composite materials

4Object-affected harmful factors

If a drainage plug is added to the backpack, then water drainage capability is improved, but the device complexity increases

Engineering Contradiction:

Improvewater drainage capabilityVSAvoiddevice complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The drainage plug is extracted as a separate, removable component from the backpack structure. This allows the drainage function to be added without permanently complicating the backpack design, and the plug can be removed or installed as needed.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The drainage plug provides a self-service solution for water drainage by allowing users to manually remove excess water from the umbrella storage compartment. This simple mechanical solution avoids the need for complex automated drainage systems.

Inventive Principle:

Principle #25Self-service
