Manual Cutting System for Disposable Surgical Materials
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for producing disposable surgical materials with hole cutouts are inefficient due to the need for frequent template changes, unwieldy repositioning of heavy punching devices, and lack of flexibility in cutting sizes and shapes, leading to slowed production processes.
Innovation Solution
A manual cutting system comprising a cutting template with a recess and a separate cutting tool with a rotatably mounted blade, allowing for flexible placement and guidance along the template's inner wall without precise positioning, enabling easy adaptation to different hole sizes and shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If punching devices are used for mass production with constant hole cutout positioning, then manufacturing precision is improved, but adaptability deteriorates due to frequent template changes and heavy device repositioning
Solution Approach 1:
The cutting system is divided into two independent components: a stationary cutting template that defines the hole cutout pattern and a mobile cutting tool that performs the cutting action. This segmentation allows the template to remain fixed for precision while the cutting tool can be easily repositioned or replaced to adapt to different cutting requirements, thereby resolving the contradiction between manufacturing precision and adaptability
Solution Approach 2:
The guide rail is designed to receive the cutting tool and guide it along the contour of the cutting template. The guide rail can be stationary or rotatably mounted on an axle, providing flexible guidance while maintaining precise cutting paths. This intermediary structure enables the cutting tool to accurately follow the template's contours without being permanently fixed, thus achieving both precision and adaptability
2Adaptability or versatility
If heavy punching devices are repositioned to adapt to different hole cutout positions, then adaptability is improved, but productivity deteriorates due to time-consuming repositioning operations
Solution Approach 1:
By separating the cutting template (stationary) from the cutting tool (mobile), the system eliminates the need to reposition heavy devices. The cutting tool can be quickly moved or replaced to adapt to different hole cutout positions while the template remains fixed, significantly reducing repositioning time and maintaining high production speed
Solution Approach 2:
The cutting tool with its guide rail effectively copies the contour pattern defined by the cutting template. This copying mechanism allows the system to produce different hole cutout positions by simply changing the template or the starting position, rather than physically repositioning heavy punching devices, thereby maintaining productivity while achieving adaptability

AI summary
The manual cutting system (1) has a cutting template (10) and a separate cutting tool (30), where the cutting template has an inner wall (12) which surrounds a recess (14). The cutting tool has a cutting blade (36) and a handle. The cutting blade is placed rotatable around a rotation axis extending in longitudinal direction. The handle is formed as a cylindrical handle sleeve with an outer wall. The cutting blade in a working position extends to a width over a lower edge of the handle sleeve such that the inner wall forms a stop for the outer wall during the cutting process. An independent claim is included for a method for the production of disposable surgical materials.
