Portable Electronic Apparatus With Combination Lock Withdrawer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for protecting portable electronic devices, such as laptop computers, are ineffective in preventing theft of the hardware storing important data, as they only secure the main body of the device without protecting the data storage components.
Innovation Solution
A portable electronic apparatus with a withdrawer system that includes a case, combination lock, and push rod, allowing the device to be locked to a base, thereby securing the data storage components like CD-ROM or hard disks from theft.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fastener is used to lock the laptop computer base to a position, then the main body of the computer is protected from theft, but the data storage devices (hard disk, CD-ROM, memory) are not protected
Solution Approach 1:
The invention divides the protection system into two independent parts: (1) the base fastener that secures the laptop body, and (2) the withdrawer with combination lock that secures data storage devices. This segmentation allows each component to perform its specific protection function independently, resolving the contradiction by expanding protection coverage to include both the main body and storage devices without interfering with each other's functionality.
Solution Approach 2:
The withdrawer is designed as a nested structure where the case containing data storage devices can be inserted into and removed from the base. The push rod mechanism is nested within the case structure. This nesting allows the protection system to be compact when not in use while providing comprehensive coverage when deployed, addressing the versatility issue by enabling protection of multiple components through a space-efficient design.
2Reliability
If the push rod penetrates through the base to fix the relative position between case and base, then the data storage device is securely locked, but the withdrawer cannot be easily removed when not needed
Solution Approach 1:
The push rod is designed as a dynamic component that can change its state between extended (penetrating through the base to lock) and retracted (withdrawn into the case for removal). The combination lock controls this dynamic state, allowing the system to transition between locked and unlocked positions. This dynamic capability resolves the contradiction by enabling both secure locking when needed and easy removal when not needed.
Solution Approach 2:
The combination lock acts as an intermediary mechanism that controls the push rod's position. When the correct combination is entered, the lock releases the push rod to extend through the base for secure locking. When locked, it prevents the push rod from extending, keeping it retracted for easy removal. This intermediary control mechanism enables both high security during locking and ease of operation during removal without compromising either requirement.

AI summary
A portable electronic apparatus including a base, a screen and a withdrawer is provided. The screen is pivotally connected to the base and the withdrawer is adopted for assembling to the base. The withdrawer includes a case, a combination lock and a push rod. The case, on which the combination lock is disposed, has an opening for exposing a part of the combination lock. The push rod disposed on the case has a first and a second end, wherein the second end is connected with the combination lock. When the combination lock is locked, the first end of the push rod penetrates through the base so as to fix the relative position between the case and the base; and when the combination lock is unlocked, the first end of the push rod can be withdrawn back into the case to separate the case from the base.
