Universal SIM Card Adapter With Elastic Stop And Snap-Fit Slot
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Different sizes of SIM cards, such as ordinary, Micro, and Nano SIM cards, pose a challenge as they cannot be easily accommodated on the same terminal, limiting user experience and compatibility.
Innovation Solution
A compatible apparatus featuring a second card slot with metal elastic pins and an elastic stop apparatus allows for the secure insertion and accommodation of various SIM card sizes by using a first card slot that snaps onto the second card slot, ensuring proper alignment and fixation of both the first and second SIM cards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If SIM cards are designed with different sizes to lock users, then user retention is improved, but device compatibility deteriorates
Solution Approach 1:
The patent implements a universal SIM card slot that can accommodate multiple SIM card sizes (standard SIM, Micro SIM, Nano SIM) through a single interface. The slot includes an elastic stop apparatus that can be adjusted to different positions to securely hold different card types, making the device compatible with various SIM formats while maintaining user retention through dual SIM functionality.
Solution Approach 2:
The patent uses a nested structure where smaller SIM cards (Micro SIM, Nano SIM) can be placed within the larger slot space. The elastic stop apparatus acts as an adjustable component that nests within the slot structure, allowing it to adapt its position to securely accommodate different sized SIM cards in the same physical space.
2Adaptability or versatility
If a single terminal supports multiple SIM card sizes, then device compatibility is improved, but structural complexity increases
Solution Approach 1:
The SIM card slot is segmented into functional components: a base slot structure, an elastic stop apparatus with multiple positioning points, and contact areas. This segmentation allows each component to perform its specific function independently, simplifying the overall design while enabling support for multiple SIM card sizes through the coordinated action of these modular elements.
Solution Approach 2:
The elastic stop apparatus provides dynamic adaptability within the slot structure. It can be positioned at different locations along the slot to accommodate various SIM card sizes, transforming a static structure into a dynamically adjustable one that maintains simplicity while achieving versatility.
3Adaptability or versatility
If elastic stop apparatus is added to accommodate smaller SIM cards, then compatibility is improved, but manufacturing complexity increases
Solution Approach 1:
The elastic stop apparatus is implemented as a flexible component that can be integrated into the slot structure. This flexible element can be manufactured as a single piece or simple assembly that provides the necessary adaptability for different SIM card sizes without requiring complex multi-component assemblies, thereby maintaining ease of manufacture while achieving compatibility.
