Bifurcated Heat Shield Mounting Bracket for Low-Deflection Wheel Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aircraft brake systems generate high temperatures that can damage wheels or tires, necessitating a heat shield to mitigate thermal damage, but existing solutions lack effective mounting configurations for robust attachment.
Innovation Solution
A heat shield assembly with a bifurcated seam mounting bracket, comprising a first and second bracket section, where the first section is indirectly mounted to the heat shield via a seam clasp, providing a secure fastening mechanism through aligned apertures, allowing for both overlying and alongside configurations for secure attachment to the wheel.

Engineering Contradiction Analysis
1Object-affected harmful factors
If a heat shield is positioned between the brake stack and the wheel to mitigate thermal damage, then thermal protection of the wheel is improved, but the mounting complexity and structural robustness deteriorate due to lack of effective mounting configurations
Solution Approach 1:
The bracket is divided into two separate sections: a first bracket section that mounts to the inner heat shield section and a second bracket section that mounts to the outer heat shield section. This segmentation allows each section to be independently optimized for its specific mounting location while collectively providing robust attachment to the complete heat shield assembly.
Solution Approach 2:
The first bracket section is disposed in overlying relation to the second bracket section, with the first bracket section nested within the spatial envelope of the second bracket section. This nesting arrangement allows both bracket sections to occupy complementary spaces and work together as an integrated mounting system without interfering with each other.
2Device complexity
If a single bracket is used to mount the heat shield, then the structure is simpler, but the attachment robustness and resistance to deflection deteriorate
Solution Approach 1:
The single bracket is segmented into two separate bracket sections that attach to different portions of the heat shield. This segmentation distributes the attachment points across multiple locations, increasing overall attachment robustness and reducing deflection while maintaining structural integrity.
Solution Approach 2:
The first bracket section and second bracket section are merged through their spatial relationship and functional integration to create a unified mounting system. The first bracket section attaches to the inner heat shield section while the second bracket section attaches to the outer heat shield section, and together they provide enhanced attachment robustness that neither section could achieve alone.
3Adaptability or versatility
If the first bracket section is indirectly mounted via a seam clasp, then the mounting flexibility and adaptability are improved, but the directness and simplicity of the mounting connection deteriorate
Solution Approach 1:
The seam clasp acts as an intermediary component between the first bracket section and the outer heat shield section. This intermediary element provides flexible attachment that accommodates manufacturing tolerances and assembly variations while maintaining a secure connection. The seam clasp can be readily installed and removed, enhancing mounting flexibility and adaptability.

AI summary
A heat shield assembly for a wheel is disclosed. The heat shield assembly includes a heat shield having a pair of heat shield ends. A bifurcated seam mounting bracket includes a first bracket section that is fixed relative one of the heat shield ends, along with a second bracket section that is fixed relative to the other of the heat shield ends. The second bracket section may be directly mounted to the heat shield. A seam clasp section may be directly mounted to both the heat shield and the first bracket section such that the first bracket section is indirectly mounted to the heat shield.
