Solution Overview

Problem

Existing wire guide locking devices often damage the wire guide due to the required wedging force and are difficult to use efficiently during medical procedures, as they require manual manipulation and visual confirmation of proper engagement.

Innovation Solution

A wire guide holder with a body and extensions that securely attach to an endoscope, allowing the wire guide to be threaded between grooved posts without pinching, providing a secure hold without damaging the wire guide and allowing for easy attachment and detachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a wedge or V-shaped slot locking device is used to lock the wire guide, then the wire guide can be secured in a stationary position, but the wire guide is damaged or stripped due to concentrated wedging force

Engineering Contradiction:
Improvewire guide securing reliabilityVSAvoidwire guide damage
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The locking force is segmented and distributed across multiple posts instead of concentrated at a single wedge location. Each post applies a portion of the total locking force, preventing localized stress that would damage the wire guide while maintaining secure positioning.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The device transitions from a concentrated locking mechanism to a distributed one where multiple posts provide localized support points. This changes the quality of force application from concentrated to distributed, protecting the wire guide from damage while maintaining locking reliability.

Inventive Principle:
Principle #3Local quality

2Ease of operation

If a J-shaped slot is used to access the wedge portion, then the locking device can be operated, but the physician must manually maneuver the wire guide in and out of the slot, which is time-consuming and distracting

Engineering Contradiction:
Improvelocking device accessibilityVSAvoidtime for wire guide maneuvering
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The complex J-shaped slot maneuvering is extracted and replaced with a simpler linear access mechanism. The wire guide can be directly inserted through a linear opening and locked by pushing against multiple posts, eliminating the need for complex curved maneuvers and visual confirmation.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The device enables self-service locking without requiring the physician to manually maneuver the wire guide through a J-shaped slot. The wire guide is simply inserted and pushed against the posts, which automatically engage the locking mechanism, making the process faster and less distracting.

Inventive Principle:
Principle #25Self-service

3Force

If a concentrated wedging force is applied to seat the wire guide into the locking slot, then the wire guide is locked, but the wire guide is kinked, stripped, or deformed

Engineering Contradiction:
Improvewedging forceVSAvoidwire guide integrity
Core Design Contradiction:
ForceVSStrength

Solution Approach 1:

The total wedging force is segmented and distributed across multiple posts. Instead of applying full force at one location, the force is divided among several posts, reducing the stress on any single point of the wire guide and preventing kinking, stripping, or deformation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The device changes the parameter of force distribution from concentrated to distributed. By spreading the locking force across multiple contact points, the system maintains the necessary locking force while changing its distribution pattern to protect wire guide integrity.

Inventive Principle:
Principle #35Parameter changes
