Aircraft Seat Fastening Hook and Pin Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening systems for aircraft seats are inefficient in terms of hooking reliability and ease of assembly/disassembly, requiring tedious and lengthy operations for operators due to complex locking and unlocking procedures.
Innovation Solution
The system employs hook-shaped heel means that engage with aircraft openings and pin-shaped locking means with elastic stress, operated via a lever, allowing for quick locking and unlocking, facilitated by latch-shaped disengageable means and rotary maneuvering tools for efficient assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex locking and unlocking procedures are used, then hooking reliability is improved, but assembly and disassembly time increases
Solution Approach 1:
The locking system is divided into distinct functional components: hooking means for engagement, pin-shaped locking means for securing, and lever-operated control mechanisms. This segmentation allows each component to perform its specific function efficiently, enabling reliable locking while maintaining quick operation through independent, simplified actions for each element.
Solution Approach 2:
The hooking means are pre-configured to automatically engage with the aircraft structure when the base is positioned, and the pin-shaped locking means are pre-positioned to protrude into the opening. This preliminary arrangement eliminates the need for complex manual manipulation during assembly, reducing time loss while maintaining reliability through pre-established secure engagement.
2Reliability
If traditional locking mechanisms are used, then secure fastening is achieved, but operator effort and complexity increase
Solution Approach 1:
The locking system employs dynamic elements including spring-loaded pin-shaped locking means that automatically engage and disengage, and lever-operated mechanisms that convert simple rotational motion into secure locking actions. This dynamic design reduces operator effort by utilizing mechanical advantage and elastic energy storage, while maintaining secure fastening through reliable engagement forces.
Solution Approach 2:
The pin-shaped locking means are spring-loaded to automatically protrude into the aircraft opening and engage the hooking means without requiring manual intervention for each locking action. The system serves itself by using stored elastic energy to maintain the locked position and automatic disengagement when the lever is operated, significantly reducing operator effort while ensuring secure fastening.

AI summary
System for fastening a seat, on the rest of an aircraft, of the type including a base associated with the rest of the seat and including hooking elements thereof on the rest of the aircraft, which can be moved between a retracted assembly/disassembly position of the seat and an active hooking position thereof on the rest of the aircraft, and locking elements for locking the hooking elements in the active position. The hooking elements include at least one hook-shaped heel to be engaged in an opening of the rest of the aircraft, and by movement of the base, under a hooking shoulder thereof, and the locking elements in the active position include pin-shaped locking members supported by the base and that can be moved between a position retracted in the base and an active position wherein the pin-shaped locking elements protrude from the base into an opening of the aircraft.
