Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing SIM card securing mechanisms for mobile phones are inadequate in ensuring secure electrical connection and easy removal of the SIM card, as they lack robustness and redundancy in fastening mechanisms.
Innovation Solution
A SIM card securing mechanism featuring a pivoted securing plate with elastic arms and protrusions that can be swiveled to securely fasten the SIM card between the plate and the phone body, utilizing the elasticity of the arms to engage with positioning holes, providing redundancy in case of damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple securing mechanism is used, then the device complexity is reduced, but the reliability of SIM card securing deteriorates
Solution Approach 1:
The securing plate is divided into multiple elastic arms (first and second elastic arms), each capable of independently engaging with positioning holes. This segmentation provides redundant securing paths, so if one arm fails, the other can still secure the SIM card, thereby improving reliability without significantly increasing overall complexity
Solution Approach 2:
The elastic arms utilize material elasticity as a key parameter to provide both securing force and flexibility. The elastic deformation allows the arms to engage reliably with positioning holes while maintaining a compact structure, achieving high reliability through material property utilization rather than complex mechanical structures
2Reliability
If a robust fastening mechanism is used, then the reliability of SIM card securing is improved, but the ease of operation for SIM card removal deteriorates
Solution Approach 1:
The securing plate is designed as a movable component that can be rotated relative to the phone body. This dynamic design allows the user to easily remove the SIM card by rotating the securing plate to a releasing position, while maintaining robust securing when in the locked position, thus resolving the contradiction between reliability and ease of operation
Solution Approach 2:
The elastic arms act as intermediaries between the securing plate and the positioning holes. Their elastic nature allows them to provide strong securing force during normal use while enabling easy release when the securing plate is rotated, as the elastic arms can flex and disengage from the positioning holes without requiring complex release mechanisms
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
The mechanism effectively secures the SIM card while allowing easy removal and maintains functionality even if one elastic arm or protrusion is damaged, ensuring reliable electrical connection and user convenience.
Implementation Method 1
The securing plate has a plurality of elastic arms each of which has a protrusion. The securing plate is capable of being swiveled to a securing position relatively to the phone body to allow the protrusions to be fastened to the positioning holes of the phone body via the elasticity of the elastic arms.

AI summary
A SIM card securing mechanism for a mobile phone is described. A phone body has several positioning holes. One side of the securing plate is pivoted in the body to allow the securing plate to swivel relatively to the phone body. The securing plate has a plurality of elastic arms each of which has a protrusion. The securing plate is capable of being swiveled to a securing position relatively to the phone body to allow the protrusions to be fastened to the corresponding positioning holes via the elasticity of the elastic arms. Thus, the SIM card is sandwiched between the securing plate and the phone.
