Solution Overview

Problem

The production of fiber composite components with two inner elements spaced apart, around which a fiber-reinforced plastics band is wrapped, is complex and lacks an efficient, automated method.

Innovation Solution

A method involving wrapping a first and second fiber-reinforced plastics band alternately around each inner element, with the bands being unwound from independent rolls and jointly rotated about a third axis to bridge the distance between the inner elements, using a rotary drive system and optional intermediate elements for support, ensuring a stable connection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If a fiber-reinforced plastics band is wrapped around two inner elements spaced at a distance, then the component achieves structural stability and load resistance, but the production process becomes complex and difficult to automate

Engineering Contradiction:

Improvestructural stabilityVSAvoidproduction process complexity

Core Design Contradiction:

Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The fiber-reinforced plastics band is divided into multiple independent bands, each wrapped around individual inner elements. This segmentation allows each band to be wrapped and cured independently, simplifying the production process while maintaining structural stability through the combined action of multiple bands

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The fiber-reinforced plastics bands are wrapped around the inner elements before the final curing process. This preliminary wrapping action allows for precise positioning and stable association to be established beforehand, making the subsequent automated production steps more straightforward

Inventive Principle:

Principle #10Preliminary action

2Reliability

If fiber-reinforced plastics bands are wrapped around inner elements to bridge the distance between them, then the component achieves stable association, but the production process requires multiple independent wrapping steps

Engineering Contradiction:

Improvestable associationVSAvoidproduction efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

Multiple fiber-reinforced plastics bands are combined in a joint wrapping process where they are wrapped alternately around the same inner elements. This merging of multiple wrapping operations into a coordinated process maintains stable association while improving production efficiency through automation

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The wrapping process is designed to wrap multiple bands continuously around the inner elements in an automated sequence, eliminating the need for separate manual wrapping steps for each band and thereby maintaining reliability while enhancing productivity

Inventive Principle:

Principle #20Continuity of useful action

AI summary

A fiber composite component has two inner elements arranged at a distance from one another, around which inner elements a fiber-reinforced plastics band is wrapped. In order to simplify the production of the fiber composite component, a first fiber-reinforced plastics band is wrapped around a first inner element, and a second fiber-reinforced plastics band is wrapped around a second inner element. The first and the second fiber-reinforced plastics band are wrapped alternately around the first and the second inner element in such a manner that the distance between the inner elements is bridged by the first and the second fiber-reinforced plastics band.
