Staggered Card Tray Structure for Thinner Mobile Device Slots
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing card tray and card holder configuration in mobile devices results in a large overall thickness due to the inclusion of a steel sheet, which hinders device miniaturization and affects user experience by consuming excessive space.
Innovation Solution
A card tray structure with staggered card slots and connecting beams that eliminate the need for a steel sheet, incorporating a supporting body with platform portions and connecting beams to enhance strength and stability, along with a sealing member and convex ribs for card retention and space efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a steel sheet is arranged in the card tray to increase thickness, then the card tray and card holder have large overall thickness, but this consumes large space and is not conducive to device thinning and miniaturization
Solution Approach 1:
The card tray is divided into multiple functional parts: a supporting body with frame edge, multiple platform portions for different card slots, and connecting beams. This segmentation allows each part to perform its specific function efficiently without requiring additional thickness from a steel sheet, as each component is optimized for its role in providing structural support and card retention.
Solution Approach 2:
The patent combines multiple functions into the card tray structure itself: the frame edge provides structural support, platform portions create card slots, connecting beams provide structural reinforcement, and sealing members provide waterproofing. By merging these functions into a single integrated structure rather than using separate layers (including a steel sheet), the overall thickness is reduced while maintaining strength.
2Length of stationary object
If the card tray structure is simplified to reduce thickness, then device miniaturization is facilitated, but card stability and sealing may be compromised
Solution Approach 1:
The card tray structure applies local quality by providing different structural characteristics at different locations: the frame edge provides overall structural support, connecting beams provide localized reinforcement where needed, platform portions provide card retention surfaces, and sealing members provide waterproofing at specific interfaces. This localized optimization ensures reliability without requiring uniform thickness throughout the entire structure.
Solution Approach 2:
The card tray uses composite construction combining rigid components (frame edge, connecting beams, platform portions) with flexible sealing members. This composite approach allows the rigid structure to provide strength and stability while the flexible sealing members provide waterproofing and adaptability, achieving both thinness and reliability through material diversity rather than uniform thickness.

AI summary
A card tray structure, a card tray assembly, and an electronic device. The card tray structure includes a card tray. The card tray includes a supporting body. The supporting body is a frame enclosed by a frame edge. A first platform portion is arranged at an edge on one side of the frame edge to form a first card slot, and a second platform portion is arranged at an edge on an other side of the frame edge to form a second card slot. The card tray further include: a first connecting beam and a second connecting beam, where the first connecting beam is arranged correspondingly to the second card slot, and the second connecting beam is arranged correspondingly to the first card slot.
