Storage Card Asymmetric Missing Corner for SIM Slot Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current storage cards face limitations in sharing a card slot with standard SIM cards due to size constraints, which restricts the capacity and area of the storage wafer that can be accommodated, leading to insufficient storage capacity.
Innovation Solution
The design of a storage card with a unique missing corner edge configuration that allows it to share a card slot with a standard SIM card, featuring a storage wafer with a vertex angle between the missing corner edge and a projection line, enabling a larger storage capacity by optimizing the edge geometry and curvature radii to fit within the same slot.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the storage card uses a standard SIM card slot size, then compatibility with standard SIM card slots is improved, but the storage wafer area is reduced
Solution Approach 1:
The storage card employs an asymmetric design by introducing a missing corner edge that does not align with the projection line of the standard SIM card's missing corner edge. This asymmetric configuration allows the storage card to fit within the standard SIM card slot while creating additional space for a larger storage wafer, thereby resolving the contradiction between slot compatibility and storage capacity.
Solution Approach 2:
The invention utilizes the dimensional space created by offsetting the missing corner edge from the projection line. By positioning the storage wafer's vertex angle between the missing corner edge and the projection line, the design effectively exploits the unused dimensional space within the standard SIM card slot boundaries, enabling larger storage capacity without compromising compatibility.
2Adaptability or versatility
If the storage card is designed to share a card slot with a standard SIM card, then card slot sharing capability is improved, but the storage capacity is limited
Solution Approach 1:
The asymmetric positioning of the missing corner edge relative to the projection line creates additional space within the standard SIM card slot. This asymmetric design enables the storage card to share the slot with standard SIM cards while accommodating a larger storage wafer, thus increasing storage capacity without sacrificing slot sharing capability.
Solution Approach 2:
By utilizing the spatial dimension created by the offset missing corner edge configuration, the invention maximizes the use of available space within the standard SIM card slot. The storage wafer is positioned to exploit this additional dimensional space, enabling higher storage capacity while maintaining compatibility for slot sharing.
3Area of stationary object
If the missing corner edge is positioned on the outer side of the projection line, then the storage wafer area is increased, but the mistake-proof design may be compromised
Solution Approach 1:
The asymmetric positioning of the missing corner edge on the outer side of the projection line is specifically designed to maintain mistake-proof functionality. The unique asymmetric configuration ensures that the storage card can only be inserted in the correct orientation, as the missing corner edge does not match the slot geometry when inserted incorrectly, thereby preserving reliability while maximizing storage wafer area.
Solution Approach 2:
By positioning the missing corner edge in a specific asymmetric location relative to the projection line, the invention creates a three-dimensional geometric constraint that maintains mistake-proof insertion. The storage wafer's vertex angle is positioned between the missing corner edge and the projection line, creating a unique geometric signature that ensures correct orientation while maximizing usable space.

AI summary
This application provides a storage card. The storage card is capable of sharing a card slot with a standard SIM card. A missing corner edge used for defining a mistake-proof missing corner is disposed on each of the storage card and the standard SIM card. When another edge of the storage card overlaps another edge of the standard SIM card, at least a part of the missing corner edge of the storage card is located on an outer side of a projection line that is of the missing corner edge of the standard SIM card and that is on the storage card. A storage wafer is disposed in the storage card, and a vertex angle of the storage wafer falls between the missing corner edge of the storage card and the projection line. In this application, the mistake-proof missing corner of the storage card is improved when the storage card shares the card slot with the standard SIM card, so that a storage wafer with a larger area and size can be placed in the storage card.
