Nested Card Connector Layout for Dual-Card Space Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Card connectors occupy a large plate area in terminal devices, restricting the development of lightweight and thin designs.
Innovation Solution
A card connector and card holder design that allows two cards to be disposed in a cascading manner on a card tray, reducing the internal space occupied by the card connector and holder, and enabling the installation of a Nano SIM card and a memory card without increasing the plate area, thus saving space for other components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple card connectors are provided in terminal devices to meet functional requirements, then the functional requirements are satisfied, but the plate area occupied by card connectors increases
Solution Approach 1:
The patent implements a nested card tray structure where a second card tray is placed inside the first card tray. The first card tray accommodates a SIM card, while the second card tray (nested within the first) accommodates a memory card. This nesting arrangement allows multiple cards to be stored in a hierarchical manner, significantly reducing the overall plate area occupied by card connectors while maintaining the ability to meet multiple functional requirements.
2Adaptability or versatility
If card connectors occupy larger plate area to accommodate multiple cards, then multiple card functions are achieved, but space inside the terminal is occupied
Solution Approach 1:
The patent implements a nested card tray structure where a second card tray is placed inside the first card tray. The first card tray accommodates a SIM card, while the second card tray (nested within the first) accommodates a memory card. This nesting arrangement allows multiple cards to be stored in a hierarchical manner, significantly reducing the overall plate area occupied by card connectors while maintaining the ability to meet multiple functional requirements.
3Adaptability or versatility
If traditional card connector designs are used, then existing card compatibility is maintained, but the plate area and internal space are excessively occupied
Solution Approach 1:
The patent designs the first card tray to be compatible with both SIM cards and memory cards. The card tray structure incorporates universal features such as elastic components that can adapt to different card types, allowing a single tray design to serve multiple functions. This multi-functionality, combined with the nested structure, enables the system to maintain broad card compatibility while significantly reducing the plate area required compared to having separate dedicated trays for each card type.
