Storage Slot Stopper Lock for Wrong-Unit Insertion Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional storage devices face challenges in accurately preventing the insertion of incorrect units due to the risk of mispositioning the stopper, leading to improper prevention of unit insertion.
Innovation Solution
A storage device with a movable stopper that can be locked into specific positions to allow or prevent the insertion of different units, where the stopper's position is determined by the type of unit inserted, ensuring correct prevention of incorrect units by using guiding pins and a lock mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the stopper is manually positioned to prevent insertion of certain units, then insertion prevention function is achieved, but the risk of mispositioning increases leading to incorrect units being prevented
Solution Approach 1:
The stopper automatically positions itself based on the type of unit inserted into the storage device. The system uses the inserted unit itself to drive the stopper to the correct position, eliminating manual positioning and ensuring accuracy without requiring user intervention.
Solution Approach 2:
The system provides feedback through the physical interaction between the inserted unit and the stopper mechanism. The shape and features of the inserted unit directly influence the stopper's position, creating a self-regulating system that ensures the correct prevention configuration is automatically established.
2Adaptability or versatility
If multiple stopper positions are provided to accommodate different unit types, then versatility is improved, but the complexity of the stopper mechanism increases
Solution Approach 1:
The stopper mechanism transitions from a static, manually-positioned system to a dynamic, automatically-positioned system. The stopper moves freely along the insertion direction and is driven to appropriate positions by the inserted units themselves, reducing mechanical complexity while maintaining versatility.
Solution Approach 2:
A single stopper mechanism serves multiple functions by automatically adapting its position based on the inserted unit type. The same stopper structure handles different unit types (first units and second units) through its movement along the insertion direction, eliminating the need for multiple specialized stoppers.
3Device complexity
If the stopper is fixed in position, then the structure is simple, but it cannot adapt to different unit types requiring insertion prevention
Solution Approach 1:
The stopper is designed to move freely along the insertion direction rather than being fixed. This dynamic capability allows the same simple stopper structure to adapt to different unit types by positioning itself appropriately, maintaining structural simplicity while achieving versatility.

AI summary
A storage device for storing units includes, a housing, wherein selective insertion of one of a first unit and a second unit that respectively have different shapes is possible, a stopper positioned such that movement is possible between an initial position, a first position wherein insertion of the first unit is allowed and insertion of the second unit is prevented, and a second position wherein insertion of the second unit is allowed and insertion of the first unit is prevented, wherein insertion of the first unit moves the stopper from the initial position to the first position and insertion of the second unit moves the stopper from the initial position to the second position, and a lock capable of locking the stopper into one of the first position and the second position.
