Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for chamfering fold formation tape ends are inefficient, requiring manual labor, complex apparatuses, and pose safety risks due to the need for multiple positioning and handling of workpieces during processing.
Innovation Solution
An apparatus with a restricting member, vertically-movable arresting force applying member, and pair of inclined form cutters that simultaneously cut and chamfer the tape ends, allowing for secure and efficient processing at two positions without operator risk.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual chamfering is used with cutter knives, then processing flexibility is maintained, but labor intensity increases and processing efficiency decreases
Solution Approach 1:
The patent replaces manual mechanical cutting operations with an automated mechanical cutting system. The apparatus uses a cutting blade mounted on a movable arm that can be positioned and actuated mechanically, eliminating the need for manual cutter knife operations while maintaining precise cutting capability through mechanical positioning and control mechanisms.
Solution Approach 2:
The apparatus enables self-service operation where the machine automatically performs positioning, cutting, and chamfering operations without continuous manual intervention. The workpiece is clamped in position, the cutting blade is automatically positioned and actuated, and the entire chamfering process occurs without operator involvement during the actual cutting action, improving both safety and efficiency.
2Productivity
If complex chamfering apparatuses are used to achieve automated processing, then productivity improves, but device complexity increases
Solution Approach 1:
The apparatus is divided into distinct functional modules: a base supporting the workpiece, a separate movable arm carrying the cutting blade, and independent positioning/control mechanisms. This segmentation allows each component to perform its specific function efficiently while simplifying the overall design and maintenance of the system.
Solution Approach 2:
The movable arm structure serves multiple functions: it supports the cutting blade, provides positioning capability, and enables controlled movement during cutting. This multi-functional design reduces the need for separate components for each function, thereby simplifying the overall apparatus while maintaining automated processing capability.
3Manufacturing precision
If multiple positioning operations are required during chamfering, then processing precision can be maintained, but processing time increases
Solution Approach 1:
The workpiece is clamped and positioned in advance on the base before the cutting operation begins. The cutting blade is pre-positioned on the movable arm with the correct cutting angle and depth settings. These preliminary positioning actions are performed once before cutting, eliminating the need for repeated positioning during the actual chamfering process, thus maintaining precision while reducing total processing time.
Solution Approach 2:
The apparatus enables continuous cutting action once the workpiece is initially positioned and clamped. The movable arm carries out the cutting motion in a continuous, controlled manner without interruption or repositioning, maintaining manufacturing precision while minimizing the time lost to repeated positioning operations.
4Productivity
If operators handle workpieces during cutting operations, then processing can be performed, but safety risks increase
Solution Approach 1:
The cutting blade is extracted from manual control and mounted on an automated movable arm system. This separation removes the operator's hands from the immediate danger zone of the cutting operation, allowing the blade to perform cutting actions autonomously while the operator maintains control from a safe distance through mechanical or automated actuation mechanisms.
Solution Approach 2:
The movable arm acts as an intermediary between the operator and the cutting blade. It transmits the cutting action mechanically or through automated control while physically separating the operator from direct contact with the blade, thereby maintaining processing capability while significantly reducing safety risks to the operator.
