Tape Cleaning Device with Intermediary Guide Body
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tape cleaning devices can adversely affect the running of recording tapes due to the suction force used to remove dust, which can cause damage or interference with the tape's operation.
Innovation Solution
A tape cleaning device comprising a blade that scrapes foreign bodies from the tape, a rotating roller to collect these foreign bodies, and a removal mechanism such as an adhesive roller or suction portion to efficiently remove them without directly affecting the tape, ensuring the tape is cleaned without disrupting its operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a suction aperture is used to remove dust from the tape surface, then dust removal effectiveness is improved, but the suction force adversely affects tape running
Solution Approach 1:
The patent introduces a guide body as an intermediary component between the suction aperture and the tape. The guide body has a suction aperture that communicates with a suction cavity, allowing dust to be removed while the guide body structure mediates the suction force to prevent direct adverse effects on tape running. This intermediary structure enables effective dust removal while protecting the tape from harmful suction forces.
2Productivity
If direct suction is applied to the tape surface, then dust removal efficiency is improved, but tape damage risk increases
Solution Approach 1:
The guide body serves as a protective intermediary that allows efficient dust removal through its suction aperture while preventing direct suction force application to the tape. The suction cavity collects dust particles that adhere to the guide body surface, and the intermediary structure ensures that high-velocity suction forces do not directly contact and damage the tape.
Solution Approach 2:
The cleaning function is segmented into multiple stages: dust particles first adhere to the guide body surface, then are collected in the suction cavity, and finally removed through the suction aperture. This segmentation allows dust removal to occur in controlled steps rather than direct suction on the tape, maintaining tape integrity while achieving efficient cleaning.
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 solution effectively cleans the recording tape without adverse effects on its running, using a simple structure that includes a housing for the blade, roller, and adhesive or suction mechanisms to prevent foreign bodies from leaking and ensure continuous tape operation.
Implementation Method 1
an adhesive roller that, while touching the roller and rotating, removes the foreign bodies on the roller by adhesive force
Implementation Method 2
a suction portion that forms a suction space between the suction portion and the roller and that removes the foreign bodies on the roller by suction force

AI summary
A tape cleaning device includes a blade that, while touching a recording tape that is running, scrapes foreign bodies from the recording tape; a roller that touches the recording tape and rotates along with the running of the recording tape, the foreign bodies scraped off by the blade being transferred to the roller; and a removal mechanism that removes the foreign bodies that have been transferred to the roller from the roller.
