Insulation Blanket with Integrated Attachment Channels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insulation blankets in aircraft compartments suffer from gaps between adjacent blankets and the compartment frame, leading to reduced insulation efficiency, moisture condensation, and undesirable air pressure and noise levels due to fluid passageways.
Innovation Solution
An insulation blanket design featuring fasteners integrated within the insulation layer, forming a channel to securely couple the blanket to the compartment frame, reducing the thickness of the insulation needed between the fastener and frame, thereby increasing clamping pressure and sealing efficiency, and using lightweight thermoplastic materials to minimize weight and the risk of foreign object debris.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If insulation blankets are installed in aircraft compartments, then thermal and acoustic insulation is improved, but gaps between blankets and frame create fluid passageways that reduce insulation efficiency and cause moisture condensation
Solution Approach 1:
The patent applies preliminary action by pre-forming channels within the insulation blanket structure before installation. These channels are designed to receive and secure the blanket to the frame members, preventing gaps and fluid passageways before they can form during operation. The blanket is prepared with attachment features that ensure proper positioning and sealing against the frame.
Solution Approach 2:
The patent implements nesting by integrating the attachment channels and fastening features directly within the layers of the insulation blanket itself. The channels are formed between the outer layer and insulation layer, embedding the attachment mechanism within the blanket structure rather than adding separate external components. This nested design ensures the blanket maintains contact with the frame while preserving insulation integrity.
2Reliability
If thicker insulation is used to prevent gaps and improve sealing, then insulation efficiency is improved, but the weight of the insulation system increases
Solution Approach 1:
The patent applies segmentation by dividing the insulation system into distinct functional layers: an outer layer, an insulation layer, and integrated channels for attachment. The fastening function is segmented from the insulation function, allowing each to be optimized independently. The channels provide structural support for sealing without requiring additional insulation thickness, maintaining weight efficiency while improving sealing performance.
3Strength
If traditional fastening methods are used to secure insulation blankets, then attachment strength is improved, but installation time increases and foreign object debris risk increases
Solution Approach 1:
The patent merges the insulation function and attachment function into a single integrated blanket structure. The channels formed between the outer layer and insulation layer serve dual purposes: maintaining insulation integrity and providing secure attachment to frame members. This combination eliminates the need for separate fastening operations, reducing installation time and minimizing foreign object debris from loose fasteners.
Solution Approach 2:
The insulation blanket is designed with self-service attachment capabilities through the integrated channels that receive and secure the blanket to frame members. The structure enables the blanket to attach itself to the frame without requiring external fastening devices or complex installation procedures. The channels are configured to automatically position and secure the blanket during installation, reducing labor time and eliminating loose fasteners that could become foreign object debris.

AI summary
Methods and apparatus for forming and installing insulation blankets in a vehicle compartment are disclosed. An example apparatus includes an insulation blanket that includes an outer layer, an insulation layer disposed in the outer layer, and a first fastener disposed in the insulation layer. The outer layer and the insulation layer are to form to a first channel. The first fastener is to receive, via the first channel, a first portion of a vehicle compartment frame to sealingly couple the insulation layer and the outer layer of the insulation blanket to the vehicle compartment frame.
