Solution Overview

Problem

The manufacturing process for composite fiber products is complex and time-consuming, requiring pre-molds and multiple steps for curing, which limits production speed and assembly efficiency.

Innovation Solution

A method involving a carrier part that acts as a replica of a press tool, allowing composite fibers to be applied and cured in place, where the carrier part becomes a permanent component of the finished product, enabling continuous production without cooling the press tool and simplifying assembly by integrating the carrier with the composite fiber part.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If traditional pre-molds are used for composite fiber manufacturing, then the manufacturing process can be simplified, but the production speed is limited and assembly complexity remains high

Engineering Contradiction:
Improvemanufacturing process simplicityVSAvoidproduction speed
Core Design Contradiction:
Ease of manufactureVSProductivity

Solution Approach 1:

The patent merges the pre-mold function with the final product carrier by integrating the composite fiber part directly onto the carrier part during curing. This eliminates the separation between temporary support structure and final product component, allowing the carrier to serve dual purposes as both manufacturing aid and functional element, thereby increasing production speed without sacrificing manufacturing simplicity

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The carrier part is prepared in advance as a replica of the press tool with pre-defined mounting features and structural elements. By performing the carrier preparation and composite fiber application in advance on the carrier part, the actual press tool can be continuously reused without waiting for cooling or complex assembly operations, thus improving productivity

Inventive Principle:
Principle #10Preliminary action

2Ease of operation

If the press tool is cooled down between curing cycles, then the composite fiber part can be removed, but production time increases

Engineering Contradiction:
Improveproduct removalVSAvoidproduction time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent extracts the composite fiber part from the press tool while the press tool remains heated, by removing only the carrier part with the cured composite fiber attached. This separation allows the press tool to maintain heating readiness for the next cycle without waiting for cooling, significantly reducing production time while still enabling easy removal of the product through carrier extraction

Inventive Principle:
Principle #2Taking out (Extraction)

3Manufacturing precision

If multiple assembly steps are used for final product construction, then manufacturing precision can be maintained, but assembly complexity increases

Engineering Contradiction:
Improveassembly precisionVSAvoidassembly complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent combines multiple assembly operations into a single integrated curing step. The composite fiber part is applied, positioned, and cured simultaneously on the carrier part in one continuous process, eliminating the need for separate assembly steps while maintaining precision through the structured carrier design that guides fiber placement and curing

Inventive Principle:
Principle #5Merging (Combining)
