Solution Overview

Problem

Existing magazine devices struggle with easy loading and unloading of rod-shaped parts, especially asymmetrical fittings like door or window hinges, due to lack of dimensional stability and complex packaging processes, which complicates automatic production and feeding into machines.

Innovation Solution

A magazine device with finger-like wall extensions that can be folded over to securely hold and easily release rod-shaped parts, eliminating the need for a cover strip and simplifying the production process by using a U-profile with a thin wall thickness, allowing for captive holding and easy detachment with minimal force.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a cover strip is used to close the receiving openings, then the rod-shaped parts are securely retained, but the packaging process becomes more complex requiring additional gluing operations

Engineering Contradiction:
Improveretention of rod-shaped partsVSAvoidpackaging structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The invention extracts the cover strip from the integrated magazine structure, making it a separate component that is not permanently attached. This allows the cover strip to be easily removed or exchanged without affecting the magazine body, thereby simplifying the packaging process while maintaining the retention function through the retaining elements on the magazine walls

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The magazine device is segmented into distinct functional components: the magazine body with retaining elements, and the separate cover strip. This segmentation allows each component to be optimized independently and simplifies assembly and disassembly operations, eliminating the need for complex gluing processes

Inventive Principle:
Principle #1Segmentation

2Stability of the object's composition

If the magazine strip is made dimensionally stable with continuous walls, then asymmetric fittings are securely held, but the production process becomes more complex

Engineering Contradiction:
Improvedimensional stabilityVSAvoidproduction process
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The magazine strip incorporates dynamic elements in the form of foldable retaining elements that can be bent into different positions. These elements provide the necessary dimensional stability when folded to hold asymmetric fittings, while their foldable nature simplifies the production process by allowing easy assembly and disassembly without complex fastening operations

Inventive Principle:
Principle #15Dynamics

3Reliability

If retaining elements are added to hold rod-shaped parts, then secure retention is achieved, but the device complexity increases

Engineering Contradiction:
Improveretention of rod-shaped partsVSAvoidmagazine structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The retaining elements are designed as thin, flexible wall extensions that can be easily folded into position. This flexibility allows the retaining elements to adapt to different rod-shaped parts while maintaining a simple overall structure, avoiding the need for complex mechanical retention mechanisms

Inventive Principle:
Principle #30Flexible shells and thin films

AI summary

The magazining device has U-shaped magazining portion with a bottom and two walls (18,19) formed with pairs of mutually opposite receiving openings for rod-shaped portion (13). The rod-shaped portions are formed with finger-like wall extensions (37) held on a bridge for retaining the rod-shaped portion between two longitudinally adjacent receiving aperture pairs and formed into a region between the walls. The finger-like wall extensions are folded to release the rod-shaped portions back to the starting position.
