Sliding Stopper for Shared Card Slot Space Utilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communications terminal products face issues with motion interference and incorrect card slot insertion when trying to share card slot space for SIM and SD cards, which also limits product size and layout flexibility.
Innovation Solution
A foolproof structure is implemented with a housing containing two card slots, a common space between them, and a sliding stopper that prevents cards from being inserted into the wrong slots, allowing for increased space utilization and reduced product size by preventing wrong insertions and card movement back to the other slot during removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two cards are placed in independent card slots, then wrong card insertion is prevented, but product size increases and space utilization decreases
Solution Approach 1:
The patent merges the card slot space for SIM card and SD card into a shared common space, allowing both cards to be inserted through a single insertion port. This reduces the overall product size while preventing wrong card insertion through a stopper mechanism that guides cards to their correct positions within the shared space.
Solution Approach 2:
The patent introduces a stopper as an intermediary component within the common card slot space. The stopper acts as a mediator that physically guides and positions cards correctly, preventing them from being inserted into wrong slots while allowing both card types to share the same insertion port.
2Volume of moving object
If two cards share the same card slot space, then product size is reduced, but motion interference occurs during card insertion and removal
Solution Approach 1:
The patent segments the common card slot space into distinct regions for SIM card and SD card using a stopper mechanism. This segmentation allows each card type to have its own designated area within the shared space, reducing motion interference during insertion and removal operations.
Solution Approach 2:
The stopper serves as an intermediary component that manages the spatial relationship between SIM card and SD card during insertion and removal. It guides cards to their correct positions and prevents motion interference by maintaining proper spacing and orientation within the shared common space.
3Volume of moving object
If two cards share the same card slot space, then space utilization increases, but cards may move back to wrong slots during removal
Solution Approach 1:
The stopper acts as an intermediary that prevents cards from moving back to wrong slots during removal operations. It maintains proper card positioning within the common space and blocks the path that would allow cards to accidentally move into incorrect slots.
Solution Approach 2:
The stopper provides preliminary anti-action by pre-positioning cards in their correct slots and preventing any potential wrong movement before it can occur. The stopper is strategically positioned to block wrong card movements during the entire insertion and removal process.

AI summary
The present invention discloses a foolproof structure for sharing card slot space, and relates to the field of communications. The foolproof structure includes a housing, where a first card slot and a second card slot are disposed inside the housing; the insertion port of the first card slot is disposed opposite the insertion port of the second card slot, a common space is disposed between the first card slot and the second card slot, a groove is disposed inside the housing of the common space, a stopper is disposed inside the groove, and the stopper can slide in the groove between the first card slot and the second card slot and is configured to prevent a card corresponding to the second card slot from being inserted into the first card slot or to prevent a card corresponding to the first card slot from being inserted into the second card slot. In the embodiments of the present invention, a stopper is configured in common space between two card slots, which solves problems of wrong card insertion and a card moving back to another card slot when being removed, increases product space utilization, and saves space, thereby reducing a size of a product that has two card slots.
