SIM Card Holder With Detachable Case And Direct Contact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices require inconvenient steps to replace SIM cards, such as opening the device cover and using a separate card socket, and often need a dedicated card socket for mounting.
Innovation Solution
An electronic device case design featuring a detachable second case with a card holding portion and a first case having a groove for direct contact with the circuit board, allowing easy attachment and detachment of the card without a separate card socket.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a card is mounted on the main body of the electronic device using a card socket, then the card can be securely held and contacted with the circuit board, but the card replacement process becomes inconvenient requiring multiple steps including opening the cover and detaching from the socket
Solution Approach 1:
The case is divided into a first case (main body) and a second case (detachable cover) with the card mounted on the second case. This segmentation allows the card to be accessed by simply detaching the second case, eliminating the need to open covers or use complex socket mechanisms, thus improving ease of operation while maintaining reliable contact through the exposed circuit board interface
Solution Approach 2:
The card socket mechanism is completely removed from the design. Instead of embedding the card in a socket on the main body, the card is extracted and mounted directly on the detachable second case, allowing direct insertion into the card slot on the first case without intermediate socket components, simplifying the replacement process
2Reliability
If a separate card socket is provided on the main body for mounting the card, then the card can be securely mounted and contacted, but the device structure becomes more complex requiring additional components
Solution Approach 1:
The card mounting function is merged with the second case (detachable cover) rather than being a separate component. The card holding portion is integrated into the second case structure, and the partition is formed from the case material itself, eliminating the need for separate card sockets and reducing overall device complexity while maintaining secure card mounting
Solution Approach 2:
The second case serves multiple functions: it acts as the detachable cover protecting the internal components, serves as the card holder with its integrated partition, and provides the interface for card insertion/removal. This multi-functionality eliminates the need for dedicated card socket components, reducing structural complexity

AI summary
An electronic device case (100) is provided. The electronic device includes a first case (110) having a first groove (112) and a second case (120). The second case (120) includes a first body (121), a connection portion (130) formed at the first body (121) so as to be coupled with the first case (110) when the first body (121) is inserted into the first groove (112), and a card holding portion (143) where a partition is formed to attach a card to the first body (121).
