Rotary SIM Card Holder Mechanism for Mobile Phone Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional SIM card securing devices in mobile phones expose the SIM card, leading to potential damage from friction and collision when the battery is changed, and the securing elastic sheets can become loose or damaged due to improper force application during insertion or removal.
Innovation Solution
A rotary SIM card securing device with a concealed design, featuring a pivotally connected SIM card holder, a restoring element, an elastic element, and a tenon structure, which allows the SIM card holder to be rotated in and out of the mobile phone's casing, ensuring secure electrical connection and protection from collisions and falls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the SIM card is exposed in the recess, then the SIM card can be easily accessed for insertion and removal, but the SIM card is vulnerable to friction and collision damage when the battery is changed
Solution Approach 1:
The SIM card holder is extracted from the recess and rotated to a safe position away from the battery installation area. This separates the SIM card from the harmful environment where friction and collision occur during battery changes, while still allowing access when needed.
Solution Approach 2:
The SIM card holder is designed to be rotatable between a concealed position (when battery is installed) and an exposed position (when SIM card needs access). This dynamic positioning allows the system to adapt between protection mode and accessibility mode, resolving the contradiction between ease of operation and protection from harmful factors.
2Reliability
If securing elastic sheets are used to fix the SIM card, then the SIM card is secured against sliding, but the elastic sheets can become loose or damaged when improper force is applied
Solution Approach 1:
The SIM card holder is extracted from the recess and rotated to a safe position away from the battery installation area. This separates the SIM card from the harmful environment where friction and collision occur during battery changes, while still allowing access when needed.
Solution Approach 2:
The SIM card holder is designed to be rotatable between a concealed position (when battery is installed) and an exposed position (when SIM card needs access). This dynamic positioning allows the system to adapt between protection mode and accessibility mode, resolving the contradiction between ease of operation and protection from harmful factors.
3Object-affected harmful factors
If the SIM card holder is concealed in the casing, then the SIM card is protected from collision, but the SIM card cannot be easily accessed for assembly and disassembly
Solution Approach 1:
The SIM card holder is designed to be rotatable between a concealed position (when battery is installed) and an exposed position (when SIM card needs access). This dynamic positioning allows the system to adapt between protection mode and accessibility mode, resolving the contradiction between ease of operation and protection from harmful factors.
Solution Approach 2:
Before accessing the SIM card, the user rotates the holder to the exposed position in advance. This preliminary action prepares the system for easy access while maintaining protection during normal operation, allowing both concealed protection and easy accessibility as needed.
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
Facilitates easy assembly and disassembly of the SIM card while maintaining electrical connection and protecting the SIM card from damage, preventing deviations and damage during battery changes.
Implementation Method 1
The SIM card holder is pivotally connected to the casing via the restoring element to allow the SIM card holder to be exposed on the top of the recess
Implementation Method 2
One end of the elastic element is fixed at the casing. One end of the tenon structure is connected to the elastic element, and the other end of the tenon structure has a second blocker. The SIM card holder may be rotated to allow the first blocker to be fastened with the second blocker via the resilience of the elastic element
