Guide Wire Protector With Segmented Half-Body Enclosure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing guide wire supply tools fail to securely protect the distal portion of a guide wire from deformation and contamination due to inadequate attachment mechanisms, which can lead to detachment and exposure during external forces or vibrations.
Innovation Solution
A protector comprising two half-bodies with guide wire and tube body sandwiching and holding portions that securely encase the distal guide wire portion, preventing deformation and detachment by using convex and concave surfaces and grooves for secure engagement, and a locking mechanism to maintain the closed state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a tubular cap is attached to the feeding-out portion using only friction, then the structure remains simple, but the cap can become detached when external forces or vibrations act on it
Solution Approach 1:
The protector is divided into two separate half-bodies that can be assembled around the feeding-out portion, creating a more complex but reliable attachment structure that prevents detachment while maintaining functionality
Solution Approach 2:
The half-bodies incorporate asymmetric convex and concave engagement surfaces that interlock to prevent detachment, transforming the symmetric simple cap structure into an asymmetric reliable connection
2Device complexity
If the cap is loosely attached to the feeding-out portion, then the structure remains simple, but the distal portion of the guide wire can be exposed, deformed, and contaminated
Solution Approach 1:
The distal portion of the guide wire is pre-positioned within the enclosed space of the two half-bodies before use, preventing exposure to harmful factors such as contamination and deformation from the outset
Solution Approach 2:
The half-bodies form an enclosed protective shell around the guide wire distal portion, creating a physical barrier that prevents contamination and deformation while allowing for the necessary structural integrity
3Reliability
If the cap is securely attached to prevent detachment, then the guide wire protection is improved, but the device structure becomes more complex
Solution Approach 1:
The protector is segmented into two half-bodies that can be separately manufactured and assembled, allowing for a more complex reliable attachment mechanism while maintaining manufacturing feasibility and assembly simplicity
Solution Approach 2:
The two half-bodies are combined to form a complete protective enclosure, merging individual simple components into a unified reliable protective structure that prevents guide wire exposure

AI summary
A protector which is used to cover a distal portion of a guide wire protruding from a distal opening of a tube body includes a first half body and a second half body which are movable between an open state and a closed state. Each of the first half body and the second half body includes a guide wire sandwiching and holding portion which mutually sandwich and hold the distal portion of the guide wire cooperatively in the closed state of the protector. Each of the first half body and the second half body also includes a tube body sandwiching and holding portion which mutually sandwich and hold the tube body cooperatively in the closed state of the protector.
