Magazine Lock Rail Structure for Stepwise Library Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional magazine extraction methods in library devices require a dedicated actuator and control circuit, increasing manufacturing costs and potentially leading to reliability and durability issues due to increased movable components.
Innovation Solution
A magazine holding structure with a rail member and lock mechanism that allows stepwise control of magazine extraction using a movement mechanism and urging member, eliminating the need for a dedicated actuator and control circuit, and reducing the number of components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a dedicated actuator and control circuit are used to extract a magazine, then the magazine extraction function is achieved, but the manufacturing cost increases and the device complexity increases
Solution Approach 1:
The magazine itself serves as the actuator through its extraction mechanism. The magazine includes a extraction mechanism that enables it to be extracted stepwise by itself without requiring an external dedicated actuator, thereby reducing device complexity and manufacturing cost
Solution Approach 2:
The accessor is given multiple functions: it not only performs cartridge extraction and insertion operations but also controls the magazine extraction process. By making the accessor universal, the need for a dedicated actuator is eliminated, reducing both device complexity and manufacturing cost
2Reliability
If a dedicated actuator and control circuit are used to extract a magazine, then the magazine extraction function is achieved, but the reliability deteriorates due to increased movable components
Solution Approach 1:
The magazine's built-in extraction mechanism reduces the number of external movable components. By making the magazine self-sufficient in its extraction capability, the system eliminates additional actuators and control circuits that would increase reliability risks
Solution Approach 2:
The extraction function is extracted from the dedicated actuator and integrated directly into the magazine structure. This removes the need for separate movable components, thereby improving reliability by reducing the number of potential failure points
3Ease of manufacture
If the magazine is extracted stepwise using a rail with stepped portions and lock member, then the manufacturing cost is reduced and reliability is improved, but the device complexity increases due to the rail and lock mechanism
Solution Approach 1:
The rail member with stepped portions and the lock member are integrated into the magazine structure itself. By merging these components with the magazine, the overall device complexity is minimized while maintaining the stepwise extraction capability, making the solution cost-effective and reliable

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution reduces manufacturing costs and enhances reliability by minimizing the number of components and movable parts, thereby reducing the risk of malfunctions during magazine extraction.
Implementation Method 1
an urging member which urges in a direction in which the rail member is installed so that a portion of the lock member located corresponding to the bottom surface of the magazine is engaged with the stepped portion

AI summary
The magazine includes a rail installed on its bottom surface approximately parallel to an insertion/extraction direction, the rail including a plurality of stepped portions formed at a side surface thereof. A device body includes: a lock lever installed rotatably within the same plane as the bottom surface of the magazine, the lock lever including one portion is located in a space below the magazine and another portion located beside the magazine; a spring which urges in a direction in which the rail is installed so that a portion of the lock lever located in a space below the magazine is engaged with the stepped portion; and an accessor which moves beside the magazine along the insertion/extraction direction. The lock lever engaged with each stepped portion is released in such a way that the accessor rotates the lock lever in an opposite direction to an urging direction of the spring.
