Solution Overview

Problem

Conventional molle backpacks are inconvenient due to the need for separate straps to be inserted and tied into strap loops for attaching and detaching pouches, requiring users to untie each strap individually for separation.

Innovation Solution

A clip with a long plate-shaped blade, a movable clip with arms and hook parts, and a locking mechanism that allows easy attachment and detachment of accessories by sliding the blade into strap loops and using the movable clip to engage and disengage with the strap loops.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If separate straps are inserted and tied into strap loops to attach pouches to backpack, then secure attachment is achieved, but operation complexity and time consumption increase

Engineering Contradiction:

Improveattachment securityVSAvoidattachment operation simplicity

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent combines multiple strap functions into a single integrated clip structure. The clip includes a blade portion that inserts through strap loops, a movable clip portion with arms that secure the straps, and a locking mechanism - all in one component. This replaces the conventional method of using separate straps that must be individually inserted and tied, achieving both secure attachment and operational simplicity.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The clip incorporates a movable clip portion that can dynamically adjust its position. The arms of the movable clip can open and close to accommodate strap insertion and secure attachment. This dynamic mechanism allows the clip to transition from an unsecured state to a locked state, providing both ease of operation and reliable attachment without requiring complex manual tying operations.

Inventive Principle:

Principle #15Dynamics

2Reliability

If separate straps are tied to attach pouches, then stable connection is achieved, but detachment time and effort increase

Engineering Contradiction:

Improveconnection stabilityVSAvoiddetachment time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The movable clip portion with its opening and closing arms provides dynamic control over the connection state. When the arms are closed, they securely hold the straps for stable attachment. When opened, they allow rapid detachment. This dynamic mechanism eliminates the need to untie individual straps, enabling both stable connection during use and rapid detachment when needed.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The locking mechanism acts as an intermediary between the blade portion and the movable clip portion. It mediates the transition between attached and detached states by engaging and disengaging the movable clip's arms. This intermediary component ensures that the connection is stable when locked but can be rapidly released when the locking mechanism is disengaged, saving time compared to manual untying of multiple straps.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Adaptability or versatility

If multiple separate straps are used for attachment, then adaptability to different pouch sizes is achieved, but device complexity increases

Engineering Contradiction:

Improvepouch size compatibilityVSAvoidclip structure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The clip is designed as a universal attachment device that can accommodate various pouch sizes and configurations. The blade portion can be inserted through different strap loop arrangements, and the movable clip's arms can adjust to secure different pouch dimensions. This single multi-functional clip replaces multiple specialized straps, achieving adaptability while reducing overall device complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Ease of manufacture

If conventional straps are used for attachment, then ease of manufacture is maintained, but operational convenience deteriorates

Engineering Contradiction:

Improveclip manufacturing simplicityVSAvoidattachment and detachment ease

Core Design Contradiction:

Ease of manufactureVSEase of operation

Solution Approach 1:

The clip is segmented into distinct functional portions: a blade portion for insertion through strap loops, a movable clip portion with arms for securing straps, and a locking mechanism for maintaining attachment. This segmentation allows each portion to be manufactured separately using simple processes and then assembled, maintaining ease of manufacture while achieving operational convenience through the coordinated function of the segmented components.

Inventive Principle:

Principle #1Segmentation
