Unloading Mechanism Assembly for Optical Disk Drive Waterproofing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional notebook computers with optical disk drives require multiple buttons and openings for unloading, which increases the risk of moisture leakage in special environments like industrial or military use, where a more streamlined and waterproof design is necessary.
Innovation Solution
An unloading mechanism assembly that uses a guiding component, push rod, and driving module to allow single-handed unloading of the optical disk drive without additional buttons or openings, utilizing a guiding component with a position limiting slot and a stroke limiting pedestal to pivotally rotate and slide the driving rod, reducing structural interference and enhancing waterproofing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple buttons and openings are provided for unloading the optical disk drive, then the unloading function is achieved, but the risk of moisture leakage increases
Solution Approach 1:
The patent combines multiple unloading functions into a single button structure. The integrated button includes a push rod that directly actuates the unloading mechanism, eliminating the need for separate positioning and exiting buttons. This merging reduces the number of openings required in the housing, thereby reducing moisture leakage risk while maintaining full unloading functionality.
Solution Approach 2:
The single button structure serves multiple functions: it provides both positioning and exiting operations for the optical disk drive unloading process. The push rod within the button structure can move in multiple directions (pushing and pulling) to achieve different unloading stages, making the single button a multi-functional component that replaces what would traditionally require multiple separate buttons.
2Ease of operation
If multiple buttons and openings are provided on the housing, then the unloading mechanism can be operated, but the structural complexity increases
Solution Approach 1:
The patent merges multiple discrete buttons and their associated openings into a single integrated button structure. This single button contains the push rod mechanism that performs both positioning and exiting operations. By consolidating these elements, the overall structural complexity is reduced while maintaining the ability to perform complete unloading operations.
Solution Approach 2:
The button structure is segmented into functional components (push rod, spring, positioning features) that work together within a single external interface. This internal segmentation allows complex functionality to be achieved while presenting a simple external form with minimal openings, effectively reducing structural complexity from the outside perspective.
3Ease of operation
If conventional buttons and openings are used for unloading, then the unloading mechanism can be implemented, but the waterproof capability is reduced
Solution Approach 1:
The patent combines all unloading operations into a single button interface, which requires only one opening in the housing. This single opening can be more effectively sealed compared to multiple openings, thereby improving waterproof capability while maintaining full unloading functionality. The integrated design allows the housing to have fewer penetration points for moisture to enter.

AI summary
An unloading mechanism assembly adapted to unload an optical disk drive from a housing of an electronic device includes a guiding component, a push rod and a driving module. The guiding component is disposed at a side of the optical disk drive along a first direction and has a first position limiting slot extending along a second direction, perpendicular to the first direction. The push rod is disposed in parallel with the guiding component along the first direction. The driving module is coupled between the guiding component and the push rod and includes a driving rod movably disposed through the first position limiting slot along a third direction, respectively perpendicular to the first and the second directions. The push rod is adapted to drive the driving module to pivotally rotate with respect to the guiding component.
