Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current protective covers for aircraft are large, bulky, and often require multiple sets, leading to storage and deployment challenges, and existing foam-based covers can damage aircraft surfaces during insertion and removal.
Innovation Solution
A collapsible protective cover made from fire-resistant ballistic fabric with programmable magnets encapsulated along the edges, allowing for reconfiguration to a small volume for storage and removable attachment to the aircraft without surface damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional foam-based covers are used to provide compressive forces for positioning and maintaining the cover in place, then the cover can withstand wind loads, but the insertion and removal of the cover damages aircraft surfaces and coatings
Solution Approach 1:
The patent replaces the mechanical foam-based compression system with a magnetic field-based attachment system. Programmable magnets embedded in the cover edges generate magnetic forces that attract to the aircraft surface, providing secure attachment without mechanical compression or friction that damages surfaces. The magnetic force can be precisely controlled and distributed to achieve strong adherence while being gentle on the aircraft coating.
Solution Approach 2:
The patent uses programmable magnets that can dynamically adjust their magnetic field strength and distribution patterns. By changing the magnetic parameters (field strength, polarity arrangement), the cover can adapt to different wind load conditions while maintaining optimal adherence without excessive force that would damage the aircraft surface. The magnets can be programmed to concentrate force in high-stress areas while reducing force in sensitive areas.
2Strength
If conventional magnets are used to provide adherence for the cover, then the cover can attach securely to the aircraft, but the field strength interferes with nearby electrical equipment and damages surface coatings
Solution Approach 1:
The patent employs programmable magnets that can create localized magnetic field patterns with different strengths in different areas. The magnetic field is concentrated precisely at the interface between the cover and aircraft surface where adherence is needed, while the field strength drops off rapidly with distance, minimizing interference with electrical equipment located elsewhere on the aircraft. Different regions of the magnet array can be independently controlled to optimize local adherence requirements.
Solution Approach 2:
The patent replaces conventional permanent magnets with programmable magnetic systems that can dynamically control field strength. This allows the system to use only the minimum necessary magnetic force for secure attachment, reducing stray field interference with electrical equipment. The programmable nature enables real-time adjustment of magnetic parameters to balance adherence requirements against electrical interference constraints.
3Reliability
If large and bulky covers are used to protect aircraft components, then the covers provide adequate protection, but the volume requires multiple sets for military aircraft deployment, increasing equipment expenditure
Solution Approach 1:
The patent uses a collapsible cover structure that can dynamically change its volume. When deployed, the cover extends to its full protective size to cover aircraft components. When not in use, the cover collapses to a compact form factor suitable for storage within the aircraft. This dynamic volume change eliminates the need for multiple cover sets, as a single cover can serve multiple deployment locations.
Solution Approach 2:
The patent implements a nested configuration where the collapsible cover can be folded or compressed into a compact form that fits within the aircraft's storage space. The cover structure allows inner layers to nest within outer layers, creating a space-efficient storage configuration that maintains full protective capability when deployed.

AI summary
A cover for an aircraft opening or equipment formed from a collapsible material having programmable magnets encapsulated on at least one edge portion to adhere the cover to an aircraft surface is provided. The programmable magnets have a close field strength sufficient to maintain the cover in place during high winds while not damaging the aircraft surface coatings during installation and removal while not interfering with electric signals or nearby electrical equipment.
