Multi-Receiving Tray for SIM and SD Cards
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with separate trays for SIM and SD cards have poor spatial usability, increased manufacturing costs, and a design disadvantage, as they cannot simultaneously use both cards.
Innovation Solution
A connector device with a multi-receiving tray that integrates plate springs and horizontally extending seats to securely hold both SIM and SD cards, allowing for individual or simultaneous use, thereby enhancing spatial usability and design while reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate trays are used for SIM and SD cards, then each card can be securely held, but spatial usability deteriorates and manufacturing costs increase
Solution Approach 1:
The patent combines two separate card trays (SIM card tray and SD card tray) into a single integrated tray structure. The tray includes a first receiving part for the SIM card and a second receiving part for the SD card, allowing both cards to be held securely in one unified component. This merging reduces the total number of trays needed, improving spatial usability while maintaining reliable card holding through dedicated receiving parts for each card type.
2Reliability
If separate trays are used for SIM and SD cards, then each card can be securely held, but manufacturing costs increase
Solution Approach 1:
The patent integrates the SIM card tray and SD card tray into a single manufactured component. The tray includes a body with integrally formed first and second receiving parts, along with plate springs and seats for both cards. This unified structure reduces manufacturing complexity and costs compared to producing and assembling separate trays, while maintaining secure card holding through dedicated receiving parts and spring mechanisms for each card type.
3Device complexity
If separate trays are used for SIM and SD cards, then structural simplicity is maintained, but the ability to simultaneously use both cards is limited
Solution Approach 1:
The patent merges the SIM card tray and SD card tray into a single integrated tray that can simultaneously accommodate both cards. The tray includes a first receiving part with a first plate spring and first seat for the SIM card, and a second receiving part with a second plate spring and second seat for the SD card. This unified structure enables simultaneous use of both cards while maintaining relatively simple construction through the shared tray body and independent spring mechanisms.
