HDD Cover Plate Mechanical Interlock with Battery Unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional notebook PCs risk damaging the HDD when removing it while the power is still on, potentially leading to data loss or rendering the disc unusable.
Innovation Solution
The design requires the battery unit to be detached before removing the HDD cover plate, ensuring the HDD is powered off during detachment by mechanically locking the cover plate in place with the battery unit attached, preventing power supply to the HDD.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the HDD is made detachable for easy maintenance and upgrade, then the ease of operation is improved, but the risk of damaging the HDD during removal increases when power is still supplied
Solution Approach 1:
The battery unit is required to be detached beforehand before removing the HDD cover plate. This preliminary action ensures that power is supplied to the HDD before the cover plate is removed, preventing the magnetic head from damaging the disc surface during HDD removal operations
Solution Approach 2:
The design creates a mechanical interlock between the battery unit and the HDD cover plate such that the cover plate cannot be removed unless the battery unit is first detached. This preliminary anti-action prevents the harmful situation of removing HDD with power still supplied by making the cover plate removal impossible under those conditions
2Adaptability or versatility
If the battery unit is made detachable for power management, then the adaptability is improved, but the complexity of the housing body structure increases
Solution Approach 1:
The battery unit is integrated with the HDD cover plate through a mechanical interlock structure. The battery unit serves dual purposes: power supply and mechanical locking of the cover plate. This merging reduces the need for separate locking mechanisms and simplifies the overall structure while maintaining the ability to manage power and access to the HDD

AI summary
An information processing apparatus in accordance with the present invention includes a battery unit 4 detachable from a first casing 1 and capable of supplying electric power to the apparatus, an HDD 8 detachable from the first casing 1 and capable of recording and reproducing data to and from an information medium, and a cover plate 5 capable of covering the HDD 8, wherein the cover plate 5 is movable between an covering position in which the HDD 8 is covered and a releasable position in which the HDD 8 can be released, and the battery unit 4 holds the cover plate 5 in place so as to be located in the covering position when the battery unit is attached to the first casing 1. With this configuration, since the HDD cannot be detached unless the battery unit is detached beforehand, the HDD can be prevented from being damaged when it is removed.
