Dual-Sided Storage Tray for Thin Electronic Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In electronic devices with a unibody structure, the thickness of the tray used for detachably mounting storage media, such as SIM and memory cards, is increased due to the need for separate seating surfaces, which hinders miniaturization and portability.
Innovation Solution
The integration of both SIM and SD card terminals onto a single surface of a storage medium, with a socket design featuring first and second conductive contacts that contact the respective terminals without interference, allowing for a thinner tray and socket configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two different types of storage media are seated on a single tray, then the tray can accommodate multiple storage media, but the thickness of the entire tray is increased
Solution Approach 1:
The patent transitions from a single-sided tray design to a double-sided tray design, utilizing both surfaces of the tray for mounting storage media. This dimensional change allows two types of storage media to be accommodated on opposite sides of the same tray without increasing the tray's thickness, as each side independently supports one type of media with its own contact structure.
Solution Approach 2:
The tray is divided into two independent functional surfaces, each with its own contact structures. The first contact structures on one side interface with the first terminal surface of the storage medium, while the second contact structures on the opposite side interface with the second terminal surface. This segmentation allows each side to be optimized independently while maintaining overall compactness.
2Strength
If a unibody structure with metal housing is used, then the exterior is beautiful and structure is strong, but the tray thickness increases to maintain expandability
Solution Approach 1:
The patent combines multiple contact structures for different storage media types into a single integrated tray assembly. By merging the first contact structures and second contact structures into one tray that accommodates both storage media simultaneously, the design maintains structural strength while avoiding the need for separate trays or increased thickness.
Solution Approach 2:
The tray is designed as a universal component that can accommodate multiple types of storage media (first type and second type) through its dual-sided configuration. This multi-functionality allows the same tray structure to serve multiple purposes without requiring additional thickness or separate structural elements.
