Aircraft Seat Mount With Locking Device For Rail Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing seat attachment systems for aircraft seats face difficulties in easy assembly and movement, as the horizontal attachment elements often interfere with the attachment rail, making it challenging to move multiple seats without disengaging them from the rail.
Innovation Solution
A seat attachment system featuring a base body with a horizontal attachment element that can be adjusted between locked and unlocked positions using a lever unit and support elements, allowing for easy coupling and decoupling from the attachment rail, with a form-fitting connection to secure the horizontal element in the unlocked position, preventing accidental re-engagement during movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the horizontal attachment element is fixed in the locked position to secure the seat in the attachment rail, then the seat is firmly fixed horizontally, but the seat cannot be moved or repositioned along the rail
Solution Approach 1:
The horizontal attachment element is designed to be dynamically adjustable between locked and unlocked positions. The locking device allows the element to switch between fixing the seat firmly in the rail (locked position) and releasing it for movement (unlocked position), transforming a static structure into a dynamic one that adapts to different operational requirements.
2Reliability
If the horizontal attachment element is designed to engage with the attachment rail for secure fixing, then the seat is firmly attached, but the element interferes with the rail when moving multiple seats
Solution Approach 1:
The locking device is designed to preliminarily position the horizontal attachment element in the unlocked state during assembly, allowing the base body to be inserted into the attachment rail without interference. Once positioned, the locking device secures the element in the locked position, ensuring firm attachment. This preliminary positioning eliminates interference during the assembly process.
3Ease of operation
If the horizontal attachment element is made adjustable between locked and unlocked positions, then the seat can be easily moved and repositioned, but the complexity of the attachment system increases
Solution Approach 1:
The locking device is designed to be operated manually by the user without requiring additional tools or complex mechanisms. The simple lever or button operation allows the user to easily switch between locked and unlocked positions, making the system self-sufficient and avoiding the need for external actuation systems that would increase complexity.
