Multi-Card Connector with Segmented Base and Spring Plates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing card connectors are limited in accommodating multiple types of cards simultaneously, restricting user selection and flexibility.
Innovation Solution
A card connector design featuring a base with distinct areas and spring plate groups, along with limiting structures and connection mechanisms, allows for the simultaneous insertion and electrical connection of multiple card types, such as Nano SIM, TF, and Micro SIM cards, by using grooves and baffle plates to secure and connect different cards in separate areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a card connector is designed to be compatible with Nano SIM or TF card using a single card tray, then the device structure is simple, but multiple types of cards cannot be placed in one card connector at the same time
Solution Approach 1:
The card connector base is divided into a first area and a second area, with separate spring plate groups and limiting structures for different card types. This segmentation allows independent accommodation of Nano SIM cards and TF cards simultaneously, resolving the contradiction between versatility and structural simplicity.
Solution Approach 2:
The card connector is designed with multi-functional areas that can accommodate different card types (Nano SIM, TF card, Micro SIM card) within a single connector structure. The first area and second area both serve card accommodation functions but with different configurations, achieving universality while maintaining reasonable structural complexity.
2Ease of operation
If a card connector accommodates only one card type at a time, then the connector structure remains simple, but user selection freedom is restricted
Solution Approach 1:
By segmenting the connector into distinct first and second areas with separate limiting structures, users can freely choose which card type to insert into which area without complicating the overall structure. Each area is optimized for specific card types, enhancing ease of operation.
Solution Approach 2:
The limiting structures act as intermediaries that guide and secure different card types in their respective areas. These structures simplify the user interaction by providing clear card placement zones while maintaining the flexibility to accommodate multiple card types.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the simultaneous placement of multiple card types in one connector, enhancing user selection freedom and experience by expanding the card placement area and ensuring secure electrical connections.
Implementation Method 1
a first spring plate group is disposed in the first area, and a second spring plate group and a third spring plate group are separately disposed in different positions of the second area; the first spring plate group is configured to electrically connect to edge connectors of the first data card
