Embedded Magnetic Head in Continuous Frame for Media Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional media processing devices face issues with jams and dust accumulation due to the discontinuous frame structure, which affects the positioning of the magnetic head and the accuracy of magnetic information reading, especially when handling misshaped media or those with weak retaining forces.
Innovation Solution
The magnetic head is embedded within the frame with part of the frame interposed between the head and the transport passage, preventing discontinuities and dust accumulation, and is secured with adhesive to ensure reliable positioning and reduce leakage flux, using a yoke configuration that maintains gap precision and directs magnetic flux effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the frame is made discontinuous to accommodate the magnetic head, then the magnetic head can be positioned for magnetization, but jams occur with misshaped media and dust accumulates at the discontinuous section
Solution Approach 1:
The magnetic head is embedded within a recess portion of the frame, creating a nested structure where the magnetic head is housed inside the frame's cavity. This allows the magnetic head to be positioned for effective magnetization while the frame remains continuous and flush with the transport passage, preventing jams and dust accumulation.
2Ease of manufacture
If the magnetic head is exposed to the transport passage for direct contact with media, then magnetization can be performed, but the frame becomes discontinuous causing structural issues
Solution Approach 1:
A recess portion is created locally in the frame at the specific position where the magnetic head needs to be mounted. This localized modification allows the magnetic head to be embedded while the rest of the frame remains continuous and structurally sound, maintaining overall frame integrity while enabling the magnetization function.
3Ease of operation
If the magnetic head is positioned protruding from the frame, then it can contact the media, but positioning precision and magnetization accuracy become difficult to control
Solution Approach 1:
The magnetic head is nested within a recess portion of the frame, which provides precise positioning and support. This embedded structure ensures accurate alignment and contact with the media during transport, eliminating positioning errors that would occur with protruding mounting while maintaining effective magnetization contact.
