Cutting Tool Container for Debris Containment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cutting tools, such as wire cutters, pose health and safety risks in medical and other applications due to sterility issues, inadequate design for precision, and the risk of high-velocity projectile debris causing accidents and trauma.
Innovation Solution
A cutting tool with a container mechanism that catches and holds cut material, featuring sterilizable design, dual-action spring loading, and a lower profile for improved visualization and safety, including handles with grip enhancements and a container to prevent material from flying away.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If common wire cutters are used in medical applications, then cutting function is provided, but sterility and safety issues arise
Solution Approach 1:
The cutting tool is divided into distinct components: reusable sterilizable handles and jaws, and disposable sterile containers. This segmentation allows the critical sterilization function to be separated from the single-use sterile barrier, ensuring both reliability and sterility without requiring the entire tool to be sterilized repeatedly.
Solution Approach 2:
The patent employs disposable sterile containers that are discarded after a single use. These containers maintain sterility guarantees without requiring complex sterilization processes, while the expensive reusable components (handles and jaws) can be sterilized and reused. This resolves the contradiction by applying disposability selectively to the components that need sterility assurance.
2Force
If thick and bulky jaws are used in cutting tools, then cutting force is sufficient, but visualization is impeded
Solution Approach 1:
The jaw design implements local quality by concentrating the cutting force application area precisely at the cutting edges while minimizing the overall jaw bulk. The container is designed with a lower profile specifically at the jaw interface to improve visualization, while maintaining sufficient structural integrity for cutting force through optimized material distribution and geometry in the force-critical regions.
3Productivity
If conventional cutting tools are used, then cutting action is provided, but high-velocity debris is generated causing safety hazards
Solution Approach 1:
The patent converts the harmful effect of sudden material release into a beneficial contained event. The container is designed to catch and retain cut materials (such as barbed hooks or wire fragments) that would otherwise become high-velocity projectiles. The container structure transforms the dangerous projectile generation into a controlled containment process, while the spring mechanism ensures the container remains closed during cutting to prevent debris escape.
4Power
If handles are designed for high force application, then cutting power is sufficient, but handling in close quarters becomes difficult
Solution Approach 1:
The handle design incorporates dynamic elements including spring-loaded mechanisms that automatically adjust to the cutting force requirements. The spring mechanism provides assistive force during cutting, reducing the manual effort needed while maintaining sufficient cutting power. This dynamic adjustment allows effective operation in close quarters without requiring excessive handle size or force application from the user.

AI summary
A cutting tool is described. The cutting tool can provide increased safety in residential, commercial, and/or medical applications. The cutting tool includes a container that can catch and/or hold material that is cut by use of the tool. This can prevent the cut material from flying indiscriminately away from the cutting tool at high velocity and can also prevent the cut material from falling to the floor/ground after cutting. The cutting tool can be sterilized for medical use, such as fish hook or jewelry removal.
