Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices often risk data loss when a user forgets to execute a program before removing a memory card, leading to potential data damage.
Innovation Solution
An extraction device with a sliding housing mechanism, elastic members, and a processor that automatically executes a data-saving program upon memory card removal, ensuring communication paths are maintained until data is securely stored.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the user manually executes a program to save data before removing the memory card, then data can be saved, but the user may forget to start the program leading to data damage
Solution Approach 1:
The extraction device automatically detects memory card removal and executes the data-saving program without requiring user intervention. The device monitors the memory card slot and autonomously initiates the save operation when card removal is detected, making the system self-protecting against data loss.
Solution Approach 2:
The device continuously monitors the state of the memory card slot and provides feedback to the control unit. When the memory card is removed, the system receives feedback about this event and automatically responds by executing the data-saving program, creating a closed-loop protection mechanism.
2Speed
If the memory card is removed immediately after detection, then the extraction is fast, but data may be damaged due to incomplete saving
Solution Approach 1:
The system performs the data-saving action in advance before the memory card is fully removed. The control unit detects removal and immediately executes the save program, ensuring data is secured before the physical card extraction completes, thus maintaining both speed and reliability.
3Reliability
If a program is executed to save data, then data loss is prevented, but the system requires user awareness and manual intervention
Solution Approach 1:
The extraction device autonomously monitors the memory card slot and automatically executes data-saving operations without requiring user awareness or manual intervention. The system serves itself by detecting card removal and initiating protection protocols independently.
Solution Approach 2:
The system implements continuous monitoring of the memory card slot state and uses this feedback to automatically trigger data-saving operations. The control unit receives real-time information about card presence and responds autonomously, eliminating the need for user involvement.
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
Prevents data loss by ensuring data is saved before the memory card is removed, even if the user forgets to initiate the program, through the use of elastic members and a processor-controlled mechanism.
Implementation Method 1
a first elastic member 80, One end of the first elastic member 80 is fixed to an inmost inner wall of the first housing 21, while the other end of the first elastic member 80 is suspended in the first housing 21
Implementation Method 2
a second elastic member 27, One end of the second elastic member 27 is fixed to the engaging member 25, while the other end of the second elastic member 27 is fixed to the body 11

AI summary
An extraction device includes a first housing, a second housing slidable received in the first housing for receiving a memory card, an engaging member, a processor, communicating pins, an identifying pin, an elastic member and a popping delay member. The engaging member engages with the second housing or disengages from the second housing. The communicating pins and the identifying pin respectively connect with communicating pin connecting portions and an identifying pin connecting portion in the second housing. The elastic member drives the second housing away from the first housing when the engaging member is disengaged from the second housing. The popping delay member delays the second housing from popping out of the first housing when the identifying pin disconnects from the identifying pin connecting portion. The processor executes a program when the identifying pin and the identifying pin connecting portion are disconnected.
