Solution Overview

Problem

Existing clip systems for securing insulation blankets to aircraft frames, such as Z frames, require specialized tools and are time-consuming and labor-intensive to install, with potential for damage to the clips.

Innovation Solution

A clip system integrally molded as a single piece of plastic, featuring adjustable clamp members with a ratchet mechanism for secure fitting to different sized structures without the need for a separate tool, and a quick-release feature for easy installation and removal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If stainless steel spring clips are used to secure insulation blankets to frames, then the clips can be secured to structures, but the installation is time-consuming and labor-intensive requiring specialized tools

Engineering Contradiction:
Improveinstallation speedVSAvoidinstallation complexity
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The clip system is designed to be self-installing without requiring specialized tools. The resilient clip members can be manually manipulated to engage with the frame and insulation blanket, eliminating the need for external installation equipment and reducing labor complexity while maintaining installation speed.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The clip system divides the securing function into separate resilient clip members that can be independently installed and adjusted. This segmentation allows for simpler, faster installation of individual clips compared to traditional single-piece fastening systems, improving overall productivity while reducing operational complexity.

Inventive Principle:
Principle #1Segmentation

2Reliability

If specialized tools are used to install spring clips, then the clips can be properly engaged, but the tools may not be readily available and installation becomes more complex

Engineering Contradiction:
Improveclip engagement reliabilityVSAvoidtool availability
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The resilient clip members are designed to be self-installing without requiring specialized tools. The natural resilience of the clip members allows them to be manually opened, positioned around the frame and insulation blanket, and secured through their own elastic properties, ensuring reliable engagement without external tool dependency.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The clip system utilizes changes in physical parameters (elastic deformation, resilient force) to enable tool-free installation. By leveraging the elastic properties of the resilient materials, the clips can be temporarily deformed for installation and then automatically return to their securing position, maintaining reliability without specialized tools.

Inventive Principle:
Principle #35Parameter changes

3Productivity

If mallet-type tools are used to tap spring clips in place, then installation may be faster, but the clips can be damaged

Engineering Contradiction:
Improveinstallation speedVSAvoidclip integrity
Core Design Contradiction:
ProductivityVSStrength

Solution Approach 1:

The resilient clip members install themselves through manual manipulation without requiring external force application tools. The clips' own elastic resilience provides the necessary force for engagement, eliminating the need for mallet-type tools that could damage the clips while maintaining efficient installation speed.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The resilient material of the clip members inherently provides cushioning and shock absorption during installation. This prior cushioning protects the clips from damage by absorbing installation forces gently, preventing the kind of impact damage that would occur with mallet-type tools while maintaining installation productivity.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

4Reliability

If traditional spring clips are used, then they can secure insulation blankets, but they are sized and shaped to fit only particular types of structures

Engineering Contradiction:
Improvesecuring capabilityVSAvoidstructure compatibility
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The resilient clip members are designed with universal adaptability to secure insulation blankets to various frame types and structures. The resilient material and configurable geometry allow the same clip design to accommodate different frame shapes and sizes, maintaining reliable securing capability across multiple application scenarios without requiring structure-specific clip variations.

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

Solution Approach 2:

The resilient clip members incorporate dynamic properties that allow them to adapt to different frame geometries. The elastic deformation capability enables the clips to conform to various frame shapes and sizes while maintaining secure engagement, providing both reliability and versatility across different structural configurations.

Inventive Principle:
Principle #15Dynamics
