Aircraft Engine Shield Installation Pole Port
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing engine shield systems are inadequate for installing on tall aircraft, as ground support personnel cannot access the engine shield due to the height of the aircraft, requiring an impractically long and unwieldy installation pole.
Innovation Solution
The engine shield system is modified to include a vertically oriented installation pole port and a universal joint connecting the installation pole port to the drive screw, allowing the installation pole to be inserted at an angle and facilitating easier access to taller aircraft engines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the installation pole is made longer to reach taller aircraft engines, then the installation reach is improved, but the pole becomes unwieldy and difficult to use
Solution Approach 1:
The installation pole port is reoriented from a horizontal orientation to a vertical orientation, changing the dimensional approach of insertion. This allows the pole to be inserted from below at an angled trajectory rather than requiring a long horizontal reach, thereby maintaining usability while achieving access to taller engines.
2Ease of operation
If the installation pole port is oriented horizontally, then the locking ring can pivot to prevent binding, but ground support personnel cannot access the port on tall aircraft
Solution Approach 1:
The installation pole port orientation is changed from horizontal to vertical, allowing insertion from a different spatial dimension (from below rather than from the side). This reorientation enables access to tall aircraft engines while maintaining the locking ring's ability to pivot and engage properly.
Solution Approach 2:
Instead of having the pole insert horizontally from the side, the system is inverted so the pole inserts vertically from below. This inversion changes the approach direction while preserving the functional relationship between the locking ring and port.
3Adaptability or versatility
If a universal joint is introduced to connect the installation pole port to the drive screw, then angled insertion is enabled, but the device complexity increases
Solution Approach 1:
A universal joint is introduced as an intermediary component between the installation pole port and the drive screw. This mediator element enables the transmission of rotational motion from the angled pole insertion to the linear motion of the drive screw, facilitating angled insertion while maintaining functional simplicity.
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
This modification enables the installation of the engine shield on tall aircraft by allowing the installation pole to be inserted at an angle, making the system more practical and usable for ground support personnel.
Implementation Method 1
a universal joint connected at a first end to the drive screw and at a second end to the cylindrical structure such that rotating the installation pole port turns the universal joint and causes the drive screw to rotate

AI summary
A system for installing a novel engine shield in the opening of an aircraft engine that is too high off the ground to be accessed by the ground support technicians while standing on the ground that includes a housing of the shield that has a front section that extends away and downward from a rear section of the housing. The front section of the housing contains an installation pole port assembly that includes an opening or port in a structure that is operably connected to a drive screw via a universal joint. In some embodiments, the installation pole port assembly is positioned to be recessed within an opening in the front section of the housing. Other versions also include a photoluminescent material applied near or around the opening in the front section of the housing.
