Portable Electronic Device SIM Card and Battery Arrangement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing structure of portable electronic devices, where the battery pack is vertically superposed on the SIM card, hinders the reduction of the device's thickness and complicates maintenance by obscuring the SIM card's presence, especially in folding or sliding designs.
Innovation Solution
A portable electronic apparatus with a unit retention mechanism for slide-mounting the SIM card and a battery retention mechanism that allows the battery pack to hold a unit lock member immobile, enabling independent location of the battery pack and SIM card in a plane, allowing for easy verification of the SIM card's presence without removing the battery pack.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the battery pack is vertically superposed on the SIM card, then the SIM card can be retained, but the thickness of the apparatus main body increases
Solution Approach 1:
The patent transitions from vertical superposition (one dimension) to horizontal arrangement (another dimension). The SIM card and battery pack are positioned side-by-side along the width direction rather than stacked vertically, thereby reducing the thickness while maintaining both components' functionality and retention reliability
2Device complexity
If the battery pack is positioned to hide the SIM card, then the structure is compact, but the SIM card presence cannot be confirmed without removing the battery pack
Solution Approach 1:
By arranging the SIM card and battery pack in different horizontal positions rather than vertical stacking, the SIM card becomes visible and accessible from the front view without requiring battery pack removal, thus maintaining structural compactness while enabling easy verification
3Reliability
If the card socket is located on the bottom portion of the battery retention mechanism, then SIM card malfunction is prevented, but the device cannot be made thinner
Solution Approach 1:
The patent repositions the card socket from the bottom portion (vertical arrangement) to a horizontal position adjacent to the battery retention mechanism. This dimensional change allows the SIM card to be inserted and retained safely without requiring the battery pack to be removed first, while simultaneously reducing the overall device thickness

AI summary
When a unit lock member (130) is engaged with a SIM card (220) mounted in a unit retention mechanism (120), a battery pack (210) can be mounted or removed. When the battery pack (210) is removed, the unit lock member (130) is permitted to slide thereby enabling mounting or removing the SIM card (220). Thus, the SIM card (220) cannot be mounted or removed while the battery pack (210) is mounted. Still, the battery pack (210) and the SIM card (220) are separately located in a plane, and hence a terminal main body (110) can be made thinner, and the presence of the SIM card (220) can be confirmed without the need to remove the battery pack (210).
