Sliding Door Gatebox with Tapered Edges for Aircraft Seeder
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional aircraft gatebox systems with hinged doors cause drag, turbulence, and uneven material distribution due to airflow obstruction, and require heavy components to handle airflow loads, while traditional seeder plates are not specifically designed and require significant resources to connect.
Innovation Solution
A sliding door gatebox with tapered edges and elastomeric seals for improved airflow management, combined with a detachable seeder plate connected via spring pins for reduced resource usage and enhanced control over material flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If hinged doors are used in traditional gatebox systems, then the doors can open and close to regulate material flow, but they cause drag and turbulence in airflow around the aircraft and require heavy components to handle airflow loads
Solution Approach 1:
Instead of hinged doors that swing into the airflow path, the patent uses sliding doors that move parallel to the airflow. This inverts the traditional door opening mechanism, allowing the door to regulate material flow without obstructing the airflow path, thereby eliminating drag and turbulence caused by hinged door operation
2Ease of operation
If hinged doors are used to regulate material flow, then the doors can control opening positions, but they require heavy components to handle the load from airflow and material
Solution Approach 1:
The sliding door mechanism inverts the traditional hinged door approach by moving the door parallel to the airflow rather than swinging it into the airflow. This eliminates the need for heavy structural components required to withstand airflow loads on hinged doors, while still providing effective material flow control through the door opening position
3Reliability
If traditional seeder plates are attached with multiple bolts, then they can be securely fixed to the gatebox, but significant resources and time are required for connection and installation
Solution Approach 1:
The seeder plate attachment system is segmented into discrete quick-connect features that allow for rapid assembly and disassembly. Instead of requiring multiple bolts to be tightened sequentially, the segmented design enables the seeder plate to be attached and detached in a single quick action, significantly reducing installation time while maintaining secure fixation
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
The sliding door gatebox reduces drag and turbulence, allows for lighter components, and provides greater control over material distribution, while the detachable seeder plate simplifies installation and reduces resource requirements.
Implementation Method 1
a seal coupled to the hopper and operable to, when the door is in the closed position, engage the edges of the door and compress to prevent material in the gatebox from being released
Implementation Method 2
a door coupled to the hopper and operable to move between an open position and a closed position by sliding along a surface of the gatebox

AI summary
A gatebox for an aircraft comprises an opening operable to allow material to flow out of the gatebox, a hopper operable to direct material in the gatebox to the opening, a door coupled to the hopper and operable to move between an open position and a closed position by sliding along a surface of the gatebox, wherein the door comprises a front edge, a rear edge wider than the front edge, and at least two side edges that taper between the front edge and the rear edge, and a seal coupled to the hopper and operable to, when the door is in the closed position, engage the edges of the door and compress to prevent material in the gatebox from being released through the opening along the engaged edge of the door.
