Solution Overview

Problem

The existing composite material panel forming process faces issues with the composite material molding source and sealing material getting stuck in the nut, leading to quality problems and decreased work efficiency due to manual replacement and potential detachment of sealing materials.

Innovation Solution

A composite material parts forming apparatus is designed with a core mounted in the press mold, an insert pin connected to the core to secure the nut, and a barrier that protrudes along the edge of the core. A sealing member is fixed between the core and the insert pin, preventing the composite material molding source from inflowing into the nut during the molding process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a sealing material (O-ring) is applied between the mold pin and the nut, then the sealing between the mold pin and the nut is improved, but the work efficiency decreases and quality problems occur due to manual replacement and potential detachment

Engineering Contradiction:
Improvesealing between mold pin and nutVSAvoidwork efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The sealing function is extracted from a separate O-ring component and integrated into the barrier structure that protrudes from the core. The barrier itself forms the sealing interface with the nut, eliminating the need for separate sealing materials that require manual installation and replacement.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The sealing function is merged with the barrier structure. The barrier that prevents molding source inflow also serves as the sealing element against the nut, combining two functions (inflow prevention and sealing) into a single integrated structure.

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If a sealing material (O-ring) is applied between the mold pin and the nut, then the sealing between the mold pin and the nut is improved, but quality problems occur due to sealing material detachment and contamination

Engineering Contradiction:
Improvesealing between mold pin and nutVSAvoidsealing material detachment and contamination
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The separate sealing material (O-ring) is removed from the system. Instead, the barrier structure itself creates the sealing interface directly with the nut through its geometric shape, eliminating the source of detachment and contamination problems.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The design eliminates disposable or temporary sealing materials that need frequent replacement. The barrier structure is a permanent, durable integral part of the core that provides continuous sealing without degradation or detachment.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

3Manufacturing precision

If the nut is not in close contact with the mold pin or there is no sealing between the mold pin and the nut, then the molding source may inflow into the interior of the nut and harden, but adding sealing material increases device complexity

Engineering Contradiction:
Improveprevention of molding source inflowVSAvoidsealing material installation
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The sealing function is merged with the barrier structure. The barrier that prevents molding source inflow also serves as the sealing element against the nut, combining two functions (inflow prevention and sealing) into a single integrated structure without adding separate components.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The barrier structure performs multiple functions simultaneously: it prevents molding source inflow into the nut cavity and creates the sealing interface with the nut. This multi-functional design eliminates the need for separate sealing components.

Inventive Principle:
Principle #6Universality (Multi-functionality)
