Smart Tablet Plug Module Single-Hand Unplugging Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing smart board plug-in module design requires simultaneous pressing of elastic strips and a pull tab for unplugging, leading to complicated operation and poor user experience due to limited size and hardware layout constraints.
Innovation Solution
A plug-in module with an elongated elastic strip and a pull tab on the same end, featuring a retraction head and limiting lugs, allowing for single-handed operation by hooking the retraction head with the handle, simplifying the plugging and unplugging process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two elastic strips are affixed onto the plug-in module and a pull tab is used for unplugging, then the plug-in module can be securely connected to the slot, but the operation becomes complicated and user experience deteriorates
Solution Approach 1:
The patent combines two separate elastic strips into a single integrated elastic strip structure. The first elastic strip has a first limiting lug and the second elastic strip has a second limiting lug, both integrated into one elastic component that engages with corresponding limiting holes in the slot. This merging reduces the number of separate components while maintaining the secure connection function, and allows the pull tab to operate both limiting lugs simultaneously, simplifying the unplugging operation.
Solution Approach 2:
The pull tab is designed to serve multiple functions: it simultaneously engages with both the first limiting lug and the second limiting lug of the elastic strip. By pulling the single pull tab, the user can disengage both limiting lugs from their respective limiting holes in the slot, achieving unplugging of the entire module with one action rather than requiring separate operations for each elastic strip.
2Ease of manufacture
If the elastic strips are positioned according to hardware layout constraints, then the structural design is feasible, but the pull tab size is limited and operation becomes difficult
Solution Approach 1:
The elastic strip is designed with an extended structure that protrudes from the plug-in module in a direction perpendicular to the insertion direction. The first and second limiting lugs are positioned at different locations along this extended elastic strip, allowing them to engage with limiting holes in the slot while the pull tab remains accessible. This dimensional arrangement allows the pull tab to be sufficiently large and accessible for easy operation while maintaining proper engagement of both limiting lugs with the slot structure.

AI summary
A plug module (100), having a first side face (110), the first side face (110) being provided with a first flexible strip (10) and a first pull tab (20) on the same end. The first flexible strip has an elongated shape, and is provided, on a first surface thereof, opposite to the first side face, with at least one first limiting lug (11). The end of the first flexible strip, where the first flexible strip and the first pull tab are located in close proximity, is considered to be the reference end, the other end being the distal end. The distal end and the first side face are fixed together. The reference end is provided with a flexible strip retraction head (12), the flexible strip retraction head being provided in correspondence with the first pull tab. Further provided is a smart tablet. The plug module can be conveniently plugged in and unplugged, simplifying user operations, improving user experience.
