Optical Pickup Lens Cleaner With Swelling Soft Cleaning Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lens cleaners for optical disk devices are ineffective in removing tar and oil deposits from pickup lenses, as they rely on bristle brushes that cannot absorb or wipe away these substances effectively.
Innovation Solution
A lens cleaner with a swelling soft member, such as a sponge or sheet-like cloth, is designed to be inserted into the optical disk device, where it is brought into contact with the pickup lens. The soft member is treated with a cleaning agent and rotated to effectively remove deposits by being pressed against the lens surface, ensuring thorough cleaning of tar and oil.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a bristle brush is used for cleaning, then the structure is simple and easy to manufacture, but the cleaning effectiveness for wiping actions is insufficient
Solution Approach 1:
The swelling soft member utilizes the moisture from the cleaning solution or ambient environment to automatically swell and expand to its functional shape. This self-activating mechanism eliminates the need for complex actuation systems while ensuring the cleaning member achieves its optimal form for effective lens contact and deposit removal
Solution Approach 2:
The cleaning member transitions from a static, compressed state during storage and insertion to a dynamic, expanded state during the cleaning operation. This dynamic transformation allows the member to adapt its physical properties in real-time based on operational conditions, enhancing cleaning effectiveness without complicating the overall device structure
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The lens cleaner ensures the removal of tough deposits like tar and oil from the pickup lens surface, providing a more effective cleaning solution compared to traditional bristle brush methods.
Implementation Method 1
a swelling soft member which is provided at a predetermined position corresponding to the objective lens on a main surface of the disk portion, and is able to be brought into contact with the objective lens when the disk portion is inserted into the optical disk device
Implementation Method 2
The user applies a cleaning agent such as alcohol to a swelling soft member (22, 42), and inserts the disk portion into the optical disk device (12) with the grip holding

AI summary
A lens cleaner (10) cleans a pickup lens (38) within an optical disk device (12). The lens cleaner (10) includes a disk portion (16) and a grip (20) provided at the rear end thereof. A user inserts the lens cleaner (10) into a slot (14) of the optical disk device (12) with the grip (20) holding with a hand (18) to thereby load the lens cleaner (10) into the interior of the optical disk device 12. When the user turns the lens cleaner (10) right and left with the grip (20) holding, a lens surface is cleaned by a cleaning member upheaving on a bottom surface of the disk portion (16).
