Solution Overview

Problem

Existing knife storage solutions do not effectively organize and secure interchangeable blade components and handles for easy access and transport, leading to potential damage and disorganization.

Innovation Solution

A knife case with hinged housing portions, blade component holders, and a handle holder, utilizing retainer members and elastomeric materials to securely store and transport knives with interchangeable blade components and handles, ensuring safe storage and easy access.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If multiple interchangeable blade components are stored separately, then organization and accessibility are improved, but device complexity increases

Engineering Contradiction:

Improveaccessibility of blade componentsVSAvoidcase structure complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The knife case is divided into multiple independent holder compartments, each specifically designed to accommodate different blade components or handle configurations. This segmentation allows organized storage of multiple interchangeable parts while maintaining a relatively simple overall case structure.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The case holders are designed with universal compatibility to accommodate various blade components and handle configurations. The same holder structure can secure different types of knife parts, reducing the need for specialized compartments for each component type.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If retainer members are used to secure blade components, then reliability of storage is improved, but ease of operation deteriorates

Engineering Contradiction:

Improvesecurity of blade componentsVSAvoidinstallation and removal of blade components

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The retainer members are designed with movable or flexible elements that allow easy engagement and disengagement. The retainers can dynamically adjust to accommodate blade insertion and removal while maintaining secure holding when the blade is in place, balancing reliability with operational ease.

Inventive Principle:

Principle #15Dynamics

3Object-affected harmful factors

If elastomeric materials are used for cushioning, then protection from damage is improved, but device complexity increases

Engineering Contradiction:

Improveprotection from damageVSAvoidcase material complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

Elastomeric materials are used to line the holders and create cushioning effects within the case structure. These flexible materials provide damage protection through shock absorption and vibration damping while being integrated into the holder design, avoiding the need for separate complex cushioning systems.

Inventive Principle:

Principle #30Flexible shells and thin films
