Solution Overview

Problem

Existing wire guiding devices require frequent replacement of worn-out eyelets, necessitating time-consuming manual intervention and disrupting production, as they cannot be rotated or replaced without cutting the wires.

Innovation Solution

A device with eyelets arranged in angular positions, detachably secured by spring-loaded, magnetic, or mechanical fastening mechanisms, allowing easy rotation and reattachment without cutting the wires.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If eyelets are fixed in the base body to guide wires, then wire guidance is stable, but eyelets wear out quickly at the contact position and require frequent replacement

Engineering Contradiction:
Improvewire guidance stabilityVSAvoideyelet service life
Core Design Contradiction:
ReliabilityVSDuration of action of stationary object

Solution Approach 1:

The eyelet is made rotatable about its longitudinal axis within the base body, transitioning from a fixed stationary position to a dynamic adjustable position. This allows the eyelet to be rotated to a fresh contact surface when wear occurs, extending its service life while maintaining stable wire guidance during operation.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The angular position of the eyelet around its longitudinal axis is changed to expose a fresh contact surface. By altering the rotational parameter of the eyelet, the system compensates for wear without replacing the eyelet, thus extending the duration of action of the stationary object.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If eyelets are replaced manually after wear, then production can continue, but the process is time-consuming and disrupts production

Engineering Contradiction:
Improveproduction continuityVSAvoideyelet replacement time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The eyelet can be rotated manually or automatically about its longitudinal axis to expose a fresh contact surface. This dynamic adjustment eliminates the need to cut wires and replace eyelets, allowing production to continue without interruption and reducing time loss.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The wire guidance function continues uninterrupted by making the eyelet rotatable. Instead of stopping production to replace worn eyelets, the system maintains continuous operation by rotating the eyelet to a fresh surface, ensuring continuity of useful action.

Inventive Principle:
Principle #20Continuity of useful action

3Stability of the object's composition

If eyelets are glued in place to secure them, then eyelets remain stable, but replacement requires heating to loosen adhesive which is complex and time-consuming

Engineering Contradiction:
Improveeyelet fixation stabilityVSAvoideyelet replacement ease
Core Design Contradiction:
Stability of the object's compositionVSEase of repair

Solution Approach 1:

The eyelet is designed to be rotatable within the base body rather than permanently fixed. This dynamic design allows the eyelet to be easily removed and repositioned without dealing with glued adhesives, simplifying repair while maintaining stability during operation.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The eyelet can be easily extracted from the base body for rotation or replacement without requiring adhesive loosening. This extraction capability simplifies the repair process compared to glued eyelets that require heating to remove.

Inventive Principle:
Principle #2Taking out (Extraction)

4Manufacturing precision

If a complex locking mechanism with locking bolts and detent positions is used to secure rotatable components, then positioning accuracy is improved, but device complexity increases significantly

Engineering Contradiction:
Improveangular position accuracyVSAvoidlocking mechanism complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The base body is segmented with multiple receptacles, each capable of receiving and rotating the eyelet independently. This segmentation allows simple rotational movement without complex locking mechanisms, reducing device complexity while maintaining positioning accuracy through the discrete receptacle structure.

Inventive Principle:
Principle #1Segmentation
