Push-Locking SIM Holder for Wireless Internet Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing wireless Internet devices face accidental network interruptions due to random plugging in and out of the SIM card holder during usage.
Innovation Solution
A push-locking apparatus is integrated into the device, comprising a push part and a locking part that slides along the device body, blocking or exposing the connection interface to securely lock the SIM card holder, preventing random insertion or removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the SIM card holder is made removable for easy installation and replacement, then the ease of operation is improved, but the reliability deteriorates due to accidental plugging in and out during usage
Solution Approach 1:
The SIM card holder employs a dynamic locking mechanism with a movable locking component that can transition between locked and unlocked states. The locking component is biased by a spring and can be actuated by a push rod to engage or disengage from the SIM card holder, providing conditional accessibility rather than permanent fixation or complete freedom of removal.
Solution Approach 2:
A locking component serves as an intermediary element between the SIM card holder and the device body. This locking component mediates the interaction by physically blocking the movement of the SIM card holder when engaged, while allowing controlled access when disengaged through the push rod actuation mechanism.
2Reliability
If a locking mechanism is added to prevent random plugging in and out, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The locking mechanism is merged with the existing SIM card holder structure by integrating the locking component directly into the SIM card holder assembly. The push rod that actuates the locking mechanism can be shared with other device functions, and the spring-loaded biasing mechanism combines multiple functions (locking force, return spring, actuation assistance) into a single integrated system.
Solution Approach 2:
The locking mechanism employs a spring-biased locking component that automatically returns to its default locked state after being actuated. The spring provides continuous locking force without requiring additional power or control systems, and the mechanism self-regulates through the mechanical interaction between the locking component, push rod, and spring.

AI summary
Embodiments of the utility model disclose a wireless Internet device. The wireless Internet device includes a device body (1) with an accommodation space, a connection interface (2) set in the accommodation space, and a subscriber identity module (SIM) card holder (3) configured to install a SIM card, where a push-locking apparatus (4, 5) is also set in the accommodation space; the push-locking apparatus (4, 5) includes a push part (41, 51) and a locking part (42, 52); the push part (41, 51) is connected to the locking part (42, 52); the push part (41, 51) slides along the device body (1); and the locking part (42, 52) releases the SIM card holder (3) in a state that the push part (41, 51) slides to block an external side of the connection interface (2), and the locking part (42, 52) locks the SIM card holder (3) in a state that the push part (41, 51) slides to expose the external side of the connection interface (2). The solution provided in the embodiments of the utility model can achieve a purpose that the SIM card holder (3) cannot be randomly plugged in and out when the wireless Internet device works.
