Solution Overview

Problem

Silicon steel bars are easily damaged during installation or removal in plastic injection molding systems due to the use of tools for quick handling, leading to deformation and inaccurate product molding.

Innovation Solution

A silicon steel bars checking device comprising a top board with grooves and holes, a bottom board with protrusions, and a block unit with threaded holes and protrusions, allowing silicon steel bars to be positioned and checked without physical contact, ensuring precise alignment and preventing damage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If tools are used to hit the silicon steel bars for quick installation or removal, then the installation speed is improved, but the silicon steel bars are damaged or deformed

Engineering Contradiction:

Improveinstallation speedVSAvoidintegrity of silicon steel bars

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent introduces a specialized fixture as an intermediary device between the user and the silicon steel bar. This fixture includes positioning structures such as V-shaped grooves, clamping mechanisms, and alignment guides that enable quick installation and removal without direct impact on the silicon steel bar itself, thereby maintaining bar integrity while improving installation speed

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the direct mechanical impact method (hitting with tools) with a controlled mechanical fixture system. The fixture uses clamping forces, positioning grooves, and alignment features to secure and manipulate the silicon steel bar, substituting the harmful impact mechanism with a controlled holding and positioning mechanism

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

If the silicon steel bars are damaged or deformed, then the handling speed is improved, but the product molding precision deteriorates

Engineering Contradiction:

Improvehandling speedVSAvoidproduct molding precision

Core Design Contradiction:

ProductivityVSManufacturing precision

Solution Approach 1:

The fixture acts as an intermediary that protects the silicon steel bar from damage during high-speed handling operations. By providing controlled positioning and support surfaces, the fixture enables fast handling while preventing deformation that would compromise molding precision

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The fixture applies preliminary protective actions by pre-positioning and securing the silicon steel bar in correct alignment before the molding process begins. The positioning structures prevent misalignment and deformation during handling, proactively preventing quality issues before they occur

Inventive Principle:

Principle #9Preliminary anti-action

AI summary

A silicon steel bars checking device includes a top board, a bottom board, a block unit and multiple bolts. A room is defined between the top board, the bottom board and the block unit. The silicon steel bars are inserted into the room and positioned between the top board, the bottom board and the block unit, and checked their specification. The silicon steel bars are removed from the device without any damage.
