Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If magazines are allowed to fall to the ground during magazine changes, then magazine change speed is improved, but magazine durability deteriorates

Engineering Contradiction:

Improvemagazine change speedVSAvoidmagazine durability

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent introduces a magazine catch apparatus as an intermediary device between the firearm and the ground. This apparatus includes a frame with a pouch that intercepts falling magazines, preventing direct impact with the ground while maintaining the speed of magazine changes. The catch apparatus acts as a mediator that protects the magazine from damage without slowing down the reloading process.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Loss of time

If magazines are allowed to fall to the ground during magazine changes, then magazine change time is reduced, but magazine damage increases

Engineering Contradiction:

Improvemagazine change timeVSAvoidmagazine damage

Core Design Contradiction:

Loss of timeVSObject-affected harmful factors

Solution Approach 1:

The magazine catch apparatus provides beforehand cushioning by positioning a soft pouch to intercept magazines before they hit the hard ground. The pouch material absorbs the impact energy, preventing damage to the magazine components such as springs, gas seals, and plastic parts, while maintaining the quick change process.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

3Strength

If a rigid frame structure is used for the catch apparatus, then structural strength is improved, but portability deteriorates

Engineering Contradiction:

Improveframe structural strengthVSAvoidportability

Core Design Contradiction:

StrengthVSEase of operation

Solution Approach 1:

The patent applies dynamics by making the frame structure collapsible rather than rigid. The frame can be collapsed into a compact configuration for easy transport and storage, then expanded to provide full structural support during use. This dynamic transformation allows the apparatus to be both strong when needed and portable when traveling.

Inventive Principle:

Principle #15Dynamics

4Strength

If the catch pouch is made of rigid material, then containment strength is improved, but adaptability to different magazine types deteriorates

Engineering Contradiction:

Improvepouch containment strengthVSAvoidcompatibility with different magazine types

Core Design Contradiction:

StrengthVSAdaptability or versatility

Solution Approach 1:

The patent uses a flexible pouch made of material such as nylon, polyester, or canvas instead of rigid material. This flexible construction allows the pouch to accommodate various magazine shapes, sizes, and types while maintaining sufficient strength to catch and contain them. The flexibility enables universal compatibility without sacrificing containment capability.

Inventive Principle:

Principle #30Flexible shells and thin films
