Aircraft Hinge Adjustment Device for Panel Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of hinged panels in aircraft interiors is often hindered by dimensional variations between components, leading to time-consuming and costly re-work, as existing technologies lack efficient methods for precise positional adjustment.
Innovation Solution
A device comprising an adjustment mechanism with an adjustment screw that allows for translation of a rotatable body along a hinge axis, enabling precise positional adjustment of panels and other movable bodies relative to a structure, including components that can be secured to surfaces transverse to the hinge axis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional fixed mounting methods are used for hinged panels, then installation is simple, but dimensional variations between components cause misalignment and require time-consuming re-work
Solution Approach 1:
The hinge assembly incorporates adjustable components that allow dynamic repositioning of the panel along the hinge axis and in transverse directions. The adjustment mechanism includes a movable element with adjustment slots and screws that enable precise positioning of the panel relative to the structure, transforming a static mounting system into a dynamic one that can accommodate dimensional variations.
Solution Approach 2:
The invention changes the positional parameters of the panel by providing an adjustment mechanism with multiple adjustment slots oriented in different directions. By moving the movable element to different positions in the adjustment slots and securing it with screws, the panel's position can be precisely adjusted along the hinge axis and in transverse directions to achieve proper alignment.
2Manufacturing precision
If adjustable mechanisms are added to accommodate dimensional variations, then alignment precision improves, but device complexity increases
Solution Approach 1:
The hinge assembly is segmented into distinct functional components: a fixed portion attached to the structure, a movable element with adjustment slots, and adjustment screws. This segmentation allows each component to perform its specific function - the fixed portion provides stable mounting, the movable element provides adjustment capability, and the screws provide securing - while maintaining overall system simplicity.
Solution Approach 2:
The adjustment mechanism serves multiple functions: it allows adjustment along the hinge axis, provides transverse adjustment capability, and enables secure locking of the panel in the desired position. This multi-functionality is achieved through a compact design where the movable element with its adjustment slots integrates several adjustment capabilities into a single component.
