Solution Overview
Problem
The repeated insertion and removal of Secure Digital (SD) cards from card slots during device manufacturing causes button displacement, leading to improper installation and potential damage to the cards, and is burdensome for testers.
Innovation Solution
A method and system that utilize a movable memory card slot with a grating sensor to convert light intensity signals into electrical signals, processed by a processor to determine and display the movement state of the slot, allowing for automatic operation and improved heat dissipation, eliminating the need for manual insertion and reducing wear on the card slot.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual insertion and removal of SD cards is performed repeatedly during device manufacture, then testing and installation can be completed, but the slot button displaces and SD cards may be damaged
Solution Approach 1:
The patent replaces manual mechanical insertion/removal operations with an automated detection system. A grating sensor detects the slot button's position and movement state, converting mechanical displacement into optical signals that are processed to determine whether the slot is properly installed. This eliminates the need for repeated manual handling during testing.
Solution Approach 2:
The system enables the device to automatically detect and determine its own installation state through the grating sensor and processing unit. The slot button's movement state is autonomously monitored, and the system can identify improper installation without external intervention, allowing for self-verification during the manufacturing process.
2Ease of manufacture
If repeated manual insertion and removal of SD cards is performed, then installation testing can be completed, but it becomes burdensome for testers and may damage the cards
Solution Approach 1:
The patent replaces manual mechanical insertion/removal operations with an automated detection system. A grating sensor detects the slot button's position and movement state, converting mechanical displacement into optical signals that are processed to determine whether the slot is properly installed. This eliminates the need for repeated manual handling during testing.
3Temperature
If a movable memory card slot is used to enable continuous operation and heat dissipation, then heat dissipation is enhanced, but the system complexity increases with grating sensor and processing requirements
Solution Approach 1:
The patent introduces a grating sensor as an intermediary component between the movable slot mechanism and the control system. The sensor converts the slot's mechanical position into optical signals, which are then processed to determine installation state. This intermediary enables automated monitoring of the movable slot without requiring complex direct mechanical sensing.

Data Source
AI summary
A method for displaying the movement state of a memory card slot is disclosed. Detection is performed to determine whether a slot button has been touched for activating. A light intensity signal is received and transformed into an electrical signal when the slot button has been activated, in which the light intensity signal represents the movement of the memory card slot. Next, the electrical signal is processed through a processor for deriving a position of the memory card slot, and the movement state is displayed according to the position of the memory card slot.
