Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fastening methods for objects to aircraft structures, such as electrical cables and insulation materials, are time-consuming, costly, and heavy due to the use of separate bolts and collars, and lack effective fire resistance.
Innovation Solution
A fastener bracket and kit utilizing a single-piece design with remoldable pins and a plate portion, where the pins are made of deformable materials that secure to the structure by heat deformation, optionally with fireproof members, and a counter component kit for enhanced stability and fire resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate bolts and collars are used to fasten objects to aircraft structures, then the fastening is secure and reliable, but the installation process becomes time-consuming and complex
Solution Approach 1:
The patent combines multiple separate fastening components (bolts and collars) into a single integrated fastener bracket assembly. The bracket is pre-assembled with integrated fastening elements, allowing the entire assembly to be installed as one unit rather than requiring separate installation of multiple components, thereby improving installation speed while maintaining fastening reliability
Solution Approach 2:
The fastener bracket is pre-assembled and prepared before installation on the aircraft structure. The bracket includes pre-positioned fastening elements and mounting features that are ready for immediate installation, eliminating the need for on-site assembly of multiple components and reducing installation time
2Reliability
If separate bolts and collars are used for fastening, then the connection is secure, but the overall weight of the fastening system increases
Solution Approach 1:
The patent integrates multiple fastening functions into a single bracket assembly, eliminating the need for separate bolts and collars. This consolidation reduces the total material used and the number of individual components, thereby reducing overall weight while maintaining the same connection security through the integrated design
Solution Approach 2:
The fastener bracket is designed as a multi-functional component that performs multiple fastening functions simultaneously. The single bracket assembly provides both structural support and secure fastening capabilities that previously required multiple separate components, reducing weight while maintaining connection security
3Ease of operation
If conventional fastening methods are used, then the installation is straightforward, but the process is costly and time-consuming
Solution Approach 1:
The fastener bracket is pre-assembled with all necessary fastening elements in their correct positions before installation. This preliminary preparation simplifies the installation process to a single mounting operation, reducing both installation time and complexity while maintaining ease of operation through the standardized design
4Reliability
If traditional fastening components are used, then the fastening is adequate, but fire resistance under abnormal heat conditions is insufficient
Solution Approach 1:
The fastener bracket incorporates fire-resistant materials and design features that maintain structural integrity under abnormal heat conditions. The bracket may include heat-resistant alloys, fireproof coatings, or design features that prevent thermal degradation, ensuring both adequate fastening and improved fire resistance simultaneously
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution simplifies and speeds up the fastening process, reduces weight, and provides improved fire resistance by maintaining functionality even under abnormal heat conditions, thus saving time, weight, and cost while ensuring secure attachment.
Implementation Method 1
By applying heat, possibly also pressure, the remoldable material contained in the pins can be deformed so as to inhibit that the pins can slip back out of the holes
Implementation Method 2
maintaining functionality even under abnormal heat conditions
