Innovation Solution

The 'Fusion X-Frame' system with a 'Frog Link' coupling device, featuring a modular, ergonomic design with carbon Kevlar construction, neodymium magnets, and RFID technology, allowing for secure and versatile attachment of various loads through a quick-release coupling mechanism.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If traditional external frame elements are used, then structural strength is provided, but weight increases and breathability decreases

Engineering Contradiction:
Improveframe structural strengthVSAvoidbackpack weight
Core Design Contradiction:
StrengthVSWeight of moving object

Solution Approach 1:

The frame is divided into multiple modular segments (upper frame, lower frame, side frames) that can be independently configured. This segmentation allows optimization of each segment's material and structure to achieve strength while minimizing weight, eliminating the need for heavy continuous external frames.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent employs composite materials combining rigid components (for structural strength) with breathable fabric panels (for weight reduction and ventilation). This composite approach maintains frame strength while significantly reducing overall weight and improving breathability compared to traditional solid external frames.

Inventive Principle:
Principle #40Composite materials

2Weight of moving object

If internal frame elements are used, then weight is reduced and breathability is improved, but attachment versatility for external gear deteriorates

Engineering Contradiction:
Improvebackpack weightVSAvoidexternal gear attachment capability
Core Design Contradiction:
Weight of moving objectVSAdaptability or versatility

Solution Approach 1:

The frame system incorporates universal attachment mechanisms (D-rings, webbing loops, quick-release clips) at multiple locations on the modular frame segments. These multi-functional attachment points enable the lightweight internal frame to securely carry various external gear including weapons, medical equipment, and survival gear, matching the versatility of traditional external frames.

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

3Reliability

If secure attachment mechanisms are used, then gear attachment reliability is improved, but ease of quick detachment deteriorates

Engineering Contradiction:
Improvegear attachment securityVSAvoidquick detachment capability
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The attachment system uses dynamic quick-release mechanisms (such as spring-loaded clips and snap-fit connectors) that provide secure locked engagement during normal use but allow rapid one-handed release when needed. This dynamic design achieves both high attachment reliability and easy quick detachment, eliminating the trade-off between security and operability.

Inventive Principle:
Principle #15Dynamics
