Solution Overview

Problem

The coupling of constructional parts in assembly processes, such as aircraft constructions, is cumbersome due to constructional variances leading to unstable connections and increased mounting time, hindering automation.

Innovation Solution

A connection interface comprising a connector with a primary and secondary fastening region and an aligner that adjusts in multiple spatial directions, using alignment elements and a measuring device to compensate for geometric differences, enabling automated alignment and assembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a dedicated joint is used to connect constructional parts, then stable connection is achieved, but mounting time increases and automatization is hampered

Engineering Contradiction:
Improveconnection stabilityVSAvoidmounting time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The connection interface is segmented into separate functional components: a connector for stable connection and an aligner for positioning. This segmentation allows the alignment function to be independently adjusted, enabling faster mounting while maintaining connection stability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The aligner incorporates adjustable elements that can dynamically adapt to constructional variances in the constructional parts. This dynamic adjustment capability allows the interface to compensate for tolerances automatically, reducing mounting time while maintaining reliable connection.

Inventive Principle:
Principle #15Dynamics

2Manufacturing precision

If alignment is provided via the joint, then constructional variances are compensated, but mounting time is enhanced and automatization is hampered

Engineering Contradiction:
Improvealignment precisionVSAvoidassembly automation
Core Design Contradiction:
Manufacturing precisionVSExtent of automation

Solution Approach 1:

The aligner acts as an intermediary element between the connector and the constructional parts. It provides the alignment function separately from the connection function, enabling standardized connectors to be used with automated positioning mechanisms, thus facilitating assembly automation while maintaining alignment precision.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The invention replaces complex mechanical alignment procedures with a standardized aligner mechanism that can be easily adjusted and potentially automated. This substitution simplifies the alignment process, making it more suitable for automated assembly systems while maintaining manufacturing precision.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Adaptability or versatility

If constructional variances are accepted, then adaptability is improved, but connection stability deteriorates

Engineering Contradiction:
Improvetolerance acceptanceVSAvoidconnection stability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The connection interface employs local quality adjustment through the aligner, which can be specifically tuned to compensate for constructional variances in each particular application. This localized adjustment maintains connection stability while accepting broader overall adaptability to different constructional configurations.

Inventive Principle:
Principle #3Local quality
