Solution Overview

Problem

Existing electroplating conductive fixtures suffer from poor contact with the conductive piece due to crystallization in the plating bath, leading to instability in current and voltage.

Innovation Solution

An electroplating conductive fixture with a spiral guide mechanism and a scraper at the bottom end of a lifting-type conductive column, which rotates and cleans the conductive piece to ensure reliable contact, utilizing a base with a first guide part and a second guide part that extend in a spiral shape to facilitate upward and downward movement, and a spring mechanism for self-restoration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the conductive piece is immersed in the plating bath, then electroplating can be performed, but crystallization occurs on the conductive piece causing poor contact with the conductive fixture

Engineering Contradiction:
Improvecontact reliabilityVSAvoidcrystallization
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The scraper is positioned in advance to contact the conductive piece before electroplating begins. During the lifting process, the scraper automatically removes crystals that have formed on the conductive piece surface, preventing contact deterioration before it affects plating quality.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The lifting mechanism itself serves dual purposes: it both raises the conductive fixture for plating operation and simultaneously activates the scraper to clean crystals from the conductive piece. The same motion that enables plating also performs the cleaning function, making the system self-maintaining.

Inventive Principle:
Principle #25Self-service

2Device complexity

If a post-shaped conductive wire is used as the conductive fixture, then the structure is simple, but contact with the conductive piece becomes poor due to crystallization

Engineering Contradiction:
Improvefixture structureVSAvoidelectrical contact
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The invention merges the conductive fixture with a scraper mechanism and a lifting system. The conductive column is integrated with a scraper at its bottom end, and the entire assembly is mounted on a lifting mechanism with spiral guide parts. This combination allows the fixture to both conduct electricity and automatically clean the contact surface.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The conductive fixture transitions from a static post-shaped wire to a dynamic system with lifting and rotating capabilities. The spiral guide parts enable rotational motion during lifting, and the scraper dynamically contacts the conductive piece to remove crystals, making the fixture adaptive to changing plating conditions.

Inventive Principle:
Principle #15Dynamics

3Stability of the object's composition

If the conductive fixture remains stationary, then the structure is stable, but it cannot remove crystals from the conductive piece causing voltage and current abnormality

Engineering Contradiction:
Improvefixture stabilityVSAvoidcurrent and voltage stability
Core Design Contradiction:
Stability of the object's compositionVSReliability

Solution Approach 1:

The fixture incorporates a lifting mechanism with spiral guide parts that enable controlled vertical and rotational motion. The conductive column can move up and down along the spiral guides, and the scraper rotates during lifting to effectively remove crystals from the conductive piece surface while maintaining overall structural stability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The lifting mechanism continuously performs dual functions: raising the conductive fixture for plating operation and simultaneously cleaning the conductive piece surface. The scraper maintains continuous contact with the conductive piece during the lifting process, ensuring uninterrupted removal of crystals and stable electrical contact throughout the plating cycle.

Inventive Principle:
Principle #20Continuity of useful action
