Solution Overview
Problem
The transfer of bulky and heavy adhesive tapes or cellophane used in semiconductor processes is challenging due to manual handling risks and potential deformation upon dropping, necessitating safe and automated transfer solutions.
Innovation Solution
A tape transfer device comprising a moving part, screw, push plate, connecting part, and clamps that facilitate the automatic and secure transfer of tapes by using a screw mechanism and clamps that protrude or retreat to fix and release the tape.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual transfer of tape is used, then operational flexibility is maintained, but safety risks and potential for injury increase
Solution Approach 1:
The tape transfer device is designed to autonomously perform the transfer operation without human intervention. The moving part automatically grasps, transports, and places the tape, making the system self-sufficient for the transfer task and eliminating the need for manual handling.
Solution Approach 2:
The patent replaces the manual mechanical handling system with an automated mechanical system. The moving part, driven by a screw mechanism, substitutes human hands and arms, providing controlled, repeatable, and safe tape transfer operations.
2Reliability
If automatic transfer device is used, then safety is improved, but device complexity increases
Solution Approach 1:
The device is divided into distinct functional components: a moving part for transport, a screw mechanism for actuation, and a clamp for securing the tape. This segmentation allows each component to be optimized independently while maintaining overall simplicity.
Solution Approach 2:
Instead of using a complex gripping mechanism, the patent uses a clamp that protrudes from and retreats into the moving part. This inverted approach simplifies the structure by using a single moving element rather than multiple coordinated actuators.
3Reliability
If clamp protrudes from shaft, then tape fixation is secure, but risk of tape deformation increases
Solution Approach 1:
The clamp protrudes only partially from the shaft, just enough to securely grip the tape without applying excessive force. This partial action provides sufficient fixation while minimizing the risk of deforming the tape material.
Solution Approach 2:
The clamp's protrusion distance is optimized to balance fixation security and tape protection. By adjusting this geometric parameter, the system achieves reliable tape holding while preventing deformation through controlled contact force and area.
