Guide Wire Insertion Aid Clamping Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional guide wire insertion aids fail to effectively suppress guide wire movement during vibrations or impacts, leading to poor usability and increased manufacturing costs due to additional parts required for stabilization.
Innovation Solution
A guide wire insertion aid with a clamping member that is resiliently flexible, allowing the guide wire to be clamped between the terminal end margin and a holding member, providing a strong sliding resistance force from two directions, and featuring a latching mechanism to maintain the guide wire in place without increasing the part count.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sliding part with a smoothly curved bridge shape is provided to suppress guide wire springing out, then the guide wire can be suppressed from springing out when vibration is applied, but the device complexity increases due to additional parts and the manufacturing cost increases
Solution Approach 1:
The patent combines the guide wire insertion aid into a single integrated body structure, eliminating the need for separate sliding parts or bridge-shaped components. The main body itself provides the guiding and stabilizing function through its internal geometry, merging multiple functions into one unified structure, thereby reducing device complexity while maintaining reliability
Solution Approach 2:
The main body of the guide wire insertion aid serves multiple functions simultaneously: it houses the guide wire, provides structural support, guides the guide wire during insertion, and stabilizes the guide wire during vibration. This multi-functional design eliminates the need for dedicated stabilization parts, reducing overall device complexity
2Reliability
If a sliding part with a smoothly curved bridge shape is provided to suppress guide wire springing out, then the guide wire can be suppressed from springing out when vibration is applied, but the manufacturing cost increases due to additional parts
Solution Approach 1:
By integrating the stabilization function into the main body structure rather than using separate sliding parts or bridge components, the patent reduces the total part count. This simplification directly lowers manufacturing costs by reducing material requirements, assembly steps, and quality control complexity while maintaining guide wire stability during vibration
3Reliability
If the clamping member is made resiliently flexible to clamp the guide wire, then the guide wire can be securely held in place, but the device complexity increases due to the movable clamping mechanism
Solution Approach 1:
The patent employs a resiliently flexible clamping member that can elastically deform to grip the guide wire securely. This flexible component provides reliable clamping through its elastic properties without requiring complex mechanical actuation systems, thereby maintaining simplicity while achieving stable guide wire retention
Solution Approach 2:
The resiliently flexible clamping member automatically engages and secures the guide wire through its elastic recovery properties. When the guide wire is inserted, the clamping member's elasticity causes it to naturally conform to and grip the guide wire without requiring additional actuators or complex control mechanisms, reducing device complexity while ensuring reliable holding
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively suppresses guide wire movement and rotation during vibrations or impacts, improving usability and reducing manufacturing costs by maintaining the guide wire in a predetermined position without the need for additional parts.
Implementation Method 1
The clamping member is resiliently flexible along its length and resiliently biased to the clamping position
Implementation Method 2
a sliding part having a smoothly curved bridge shape is provided to suppress the guide wire from springing out when vibration is applied. When doing so, the sliding part raises the guide wire upward that sticks out from the receptacle supporter and applies a slide resistance force by the bridge shape to add constraint to the free movement of the wire

AI summary
A guide wire insertion aid that is an aid for dispensing a guide wire inserted in a wire receptacle and inserting the guide wire into a cavity of a medical instrument. The insertion aid includes a holding member and a clamping member connected to a main body portion. The clamping member is movable relative to the main body portion between a clamping position, in which the terminal end margin of the clamping member is configured to engage the guide wire and clamp the guide wire between the terminal end of the clamping member and the holding member, and a non-clamping position, in which the terminal end margin of the clamping member is configured to disengage the guide wire and allow free movement of the guide wire.
