Electronic Device Tray Power Management for Multi-Media Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face challenges in efficiently attaching and detaching multiple external storage media without causing data loss or faults, due to the complexity of managing power contacts during attachment and detachment.
Innovation Solution
An electronic device with a plug-in apparatus that allows simultaneous attachment of multiple external storage media, featuring a socket with specific contact arrangements and a power management circuit to prevent unintended power supply to external storage media during attachment or detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple external storage media are attached to respective holders at different locations, then the capability to simultaneously use multiple external storage media is improved, but the device size increases and user convenience deteriorates
Solution Approach 1:
The patent combines multiple storage media attachment capabilities into a single integrated holder structure. The holder is designed with multiple slots or compartments that can accommodate several external storage media simultaneously, allowing users to attach and detach multiple media at once from one location rather than managing separate holders at different device locations.
2Adaptability or versatility
If multiple external storage media are attached to respective holders at different locations, then the capability to simultaneously use multiple external storage media is improved, but the device size increases
Solution Approach 1:
The patent consolidates multiple storage media attachment functions into a single integrated holder structure. The holder contains multiple slots or compartments that can accommodate several external storage media simultaneously, reducing the overall device footprint by eliminating the need for separate holders distributed across different device locations.
3Ease of operation
If power is supplied during attachment or detachment of external storage media, then the external storage medium can be electrically connected, but unintended power supply to wrong contacts causes data loss or faults
Solution Approach 1:
The patent implements a detection mechanism that identifies whether an external storage medium is properly attached before initiating power supply. The system first detects the presence and proper positioning of the storage medium, then activates power supply only after confirming correct attachment. This preliminary detection prevents unintended power supply to wrong contacts that could cause data loss or faults.
