Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tow hooks are not versatile enough to engage with various types of airplane nose gears, limiting their application in aircraft towing.
Innovation Solution
A plural function tow hook design featuring dual prongs or hook elements and a clevis pin system that can engage different nose gear configurations, allowing a single tow hook to be used across multiple aircraft types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single-style tow hook is used, then the structure is simple and easy to manufacture, but it cannot engage with various types of airplane nose gears
Solution Approach 1:
The tow hook is designed with multiple engagement configurations, allowing a single device to engage with different nose gear types (pin-style, bar-style, and other configurations). The hook can be positioned in various orientations and engaged with different attachment points, making it a universal towing solution that replaces multiple specialized hooks.
Solution Approach 2:
The tow hook incorporates movable and adjustable components that allow it to adapt its configuration dynamically. The hook can be repositioned along the strut and engaged in different orientations depending on the nose gear type, providing flexibility without requiring multiple fixed-design hooks.
2Adaptability or versatility
If multiple specialized tow hooks are used for different nose gear types, then each hook is optimized for its specific function, but the overall system becomes complex and requires multiple devices
Solution Approach 1:
Instead of requiring separate tow hooks for pin-style nose gears, bar-style nose gears, and other configurations, this invention provides a single multi-functional hook that can engage with all these types. The hook's ability to be positioned and engaged in multiple configurations eliminates the need for maintaining an inventory of multiple specialized hooks.
Solution Approach 2:
The invention merges the functions of multiple specialized tow hooks into a single device. By combining the engagement capabilities for different nose gear types into one hook design, it reduces the quantity of equipment needed while maintaining full functionality across all applications.
3Adaptability or versatility
If a universal tow hook design is used, then it can engage various nose gear types, but the engagement mechanism becomes more complex
Solution Approach 1:
The tow hook utilizes dynamic positioning capabilities that allow it to adapt to different engagement points on various nose gear types. The movable components enable the hook to be quickly repositioned and engaged without complex adjustment mechanisms, maintaining ease of operation while achieving universality.
Solution Approach 2:
The engagement mechanism is divided into discrete, simple steps that can be performed sequentially. The hook's design allows for straightforward engagement with different nose gear types through a series of simple positioning and securing actions, rather than requiring a single complex mechanism.

AI summary
A plural function tow hook is described for engaging airplane nose gears having nose gears of different styles. Consequently, a single tow hook can be used in multiple applications for aircraft towing purposes. The tow hook receives and engages a pin of a nose gear for use in towing the aircraft in one application. The tow hook receives first and second loops of a tow strap passing around a strut of an airplane nose gear in another application.
