Detachable Memory Docking Structure to Prevent Misplugging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current detachable memory assemblies in electronic devices often result in misplugging, where the memory is partially inserted, leading to unstable connections and potential device crashes or data loss, due to the difficulty in detecting incomplete docking and the ability of devices to read misplugged memories.
Innovation Solution
Incorporating a stopping portion and a stopped portion in the detachable memory and electronic device, which form a displacement space, requiring correct alignment and rotation for full docking, preventing horizontal insertion and ensuring complete coupling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the memory is pressed horizontally into the accommodating slot without attention, then the assembly process is simple and fast, but the memory becomes misplugged leading to unstable connection and device crashes
Solution Approach 1:
The stopping portion is designed to be asymmetric relative to the accommodating slot, creating a specific insertion direction. The stopped portion on the memory has a corresponding asymmetric shape that only fits when inserted correctly, preventing horizontal misplugging while maintaining simple operation.
Solution Approach 2:
The stopping portion is pre-positioned in the accommodating slot to create a displacement space that guides the stopped portion during insertion. This preliminary structural arrangement ensures that correct alignment occurs automatically during the insertion process, preventing misplugging before it can happen.
2Reliability
If the memory is fully pressed into the accommodating slot, then thorough coupling is achieved allowing the device to read the memory, but the user cannot detect misplugging and stable assembly cannot be maintained
Solution Approach 1:
The asymmetric design of the stopping and stopped portions ensures that misplugged memories cannot be fully inserted. The structural mismatch becomes visually and physically apparent when the memory fails to seat properly, making misplugging easily detectable while still allowing thorough coupling when correctly assembled.
Solution Approach 2:
The stopping portion creates a preliminary barrier that prevents misplugged memories from achieving full insertion. This anti-action occurs before the memory can be fully coupled, providing both physical prevention and visual indication of incorrect assembly through the displacement space.
3Reliability
If a stopping portion and stopped portion are added to prevent misplugging, then connection stability is improved, but the device complexity increases
Solution Approach 1:
The anti-misplugging function is segmented into two separate components: a stopping portion integrated into the accommodating slot and a stopped portion integrated into the memory. This segmentation allows each component to maintain its primary function while adding the anti-misplugging capability, minimizing overall structural complexity.
Solution Approach 2:
The stopping portion is merged with the accommodating slot structure, and the stopped portion is merged with the memory body, combining multiple functions into existing components. This merging approach prevents misplugging without requiring entirely separate additional structures, thereby limiting the increase in device complexity.

AI summary
An electronic device having a detachable memory is provided with a docking connector, and includes a device body and a memory. The device body has an accommodating slot and a stopping portion provided corresponding to the accommodating slot, and the stopping portion and the accommodating slot jointly form a displacement space in between. The memory is provided with a connector and a protruding stopped portion. When the memory is accommodated in the accommodating slot, the stopped portion is moved along into the displacement space and is stopped by the stopping portion, and the connector is docked with the docking connector. Thus, the memory is provided with an anti-misplugging effect.
