Solution Overview

Problem

The existing mounting arrangements for electrical lines in aircraft and spacecraft require multiple sizes of holders to accommodate varying numbers of modules, leading to high production and storage costs due to the need for different holder sizes.

Innovation Solution

A mounting arrangement with a U-shaped holder featuring a central portion of changeable length, allowing for easy adjustment by shortening or lengthening, and modular elements that can be interconnected to accommodate different configurations, reducing the need for multiple holder sizes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If holders of different sizes are produced to accommodate varying numbers of modules, then the mounting arrangement can adapt to different configurations, but production costs and storage costs increase

Engineering Contradiction:

Improveadaptability to different module configurationsVSAvoidproduction cost and storage cost

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The holder is divided into a standardized body and interchangeable extensions. The extensions can be attached or removed to adjust the holder length, allowing a single standardized holder design to accommodate varying module configurations without producing multiple complete holder sizes

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A single standardized holder design serves multiple functions by accepting different numbers and configurations of modules through interchangeable extensions. This universal design eliminates the need for multiple specialized holder sizes, reducing production and storage costs while maintaining adaptability

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If holders of different sizes are produced for different applications, then specific applications can be optimized, but the complexity of managing multiple holder sizes increases

Engineering Contradiction:

Improveapplication-specific optimizationVSAvoidnumber of different holder sizes

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The holder system is segmented into a standardized base unit and modular extensions. This segmentation allows the system to maintain a simple standardized core design while achieving application-specific configurations through optional extensions, reducing the complexity of managing multiple complete holder designs

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The holder configuration is made dynamic and adjustable rather than fixed. Interchangeable extensions allow the holder to be adapted to different applications as needed, eliminating the need to produce and manage multiple static holder sizes for different applications

Inventive Principle:

Principle #15Dynamics
