Innovation Solution
A linking device with a first and second portion connected to the frame and stringer, respectively, and an intermediary portion allowing for relative movement via articulations along perpendicular and parallel rotation axes, enabling adjustable angles and simplified assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple models of stabilizers with different dimensions and geometries are provided to accommodate varying angles and curvatures, then the adaptability to different implantation areas is improved, but the device complexity and inventory management difficulty increase
Solution Approach 1:
The patent applies universality by designing a single stabilizer model that can perform multiple functions across different implantation areas. The stabilizer incorporates adjustable components (articulated connections with rotation axes) that allow it to adapt to various angles and curvatures, replacing the need for multiple specialized models. This enables one stabilizer design to serve multiple purposes in different structural contexts.
Solution Approach 2:
The patent applies dynamics by introducing articulated connections with rotation axes that allow the stabilizer to dynamically adjust its configuration. The first articulation with rotation axis R1 and the second articulation with rotation axis R2 enable the stabilizer to change its geometry and angles during assembly, allowing it to accommodate varying implantation areas without requiring multiple fixed-geometry models.
2Adaptability or versatility
If multiple models of stabilizers with different dimensions and geometries are provided, then the adaptability to different implantation areas is improved, but the assembly time and operator difficulty increase
Solution Approach 1:
The universal stabilizer design eliminates the need for operators to search through and select among multiple models during assembly. The single standardized model with adjustable features can be used in all implantation areas, significantly reducing assembly time by eliminating the selection process and enabling consistent assembly procedures across different locations.
Solution Approach 2:
The dynamic adjustment capabilities through articulated connections allow operators to quickly adapt the stabilizer to different angles and curvatures during assembly, rather than requiring pre-selection of specific models. This reduces assembly time by enabling on-the-fly adjustment to match the required implantation geometry.
3Manufacturing precision
If stabilizers with different dimensions and geometries are used, then the linking accuracy for curved stringers is improved, but the manufacturing complexity increases
Solution Approach 1:
The articulated connections with rotation axes enable the stabilizer to achieve precise linking accuracy for curved stringers through mechanical adjustment rather than through complex manufacturing. The ability to rotate at two different axes allows the stabilizer to conform to various curvatures and angles, maintaining high precision without requiring multiple specialized geometries.

AI summary
A device for linking a frame and a stringer of an aircraft structure, including a first portion connected to a support surface of a frame, a second portion connected to a support surface of a stringer and a third portion referred to as intermediary portion connecting the first portion to the second portion. The second portion is connected to the intermediary portion by means of an articulation allowing for a relative movement between the two portions along a rotation axis perpendicular to the support surface of the stringer. The first portion is connected to the intermediary portion by means of an articulation allowing for a relative movement between the two portions along a rotation axis parallel to the support surface of the frame and to the support surface of the stringer.
