Aircraft Wing Support Structure Centric Force Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aircraft frameworks face challenges in efficiently transferring substantial forces while minimizing weight, as existing support structures require heavy components to handle loads, leading to increased weight and production complexities due to the need for complex connections and large components.
Innovation Solution
A support structure design featuring a bar element with a transition region that overlaps and engages a junction element, allowing for centric force transmission without moments, using a connection element with varying cross-sectional shapes and materials to optimize force distribution and reduce weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If solid bar profiles (U-profiles or double T-profiles) are used to construct highly loadable frameworks, then the framework can accommodate substantial forces, but the weight of the framework increases significantly
Solution Approach 1:
The framework is divided into separate bar elements that can be connected through junction elements, allowing each component to be optimized independently for strength-to-weight ratio while maintaining overall structural integrity
Solution Approach 2:
The patent employs composite construction by combining bar elements with junction elements featuring transition regions, creating a hybrid structure that achieves high strength without requiring solid throughout the entire framework
2Strength
If complex connections are used at framework junction points to accommodate substantial forces, then the structural strength is improved, but the device complexity and production difficulty increase
Solution Approach 1:
Junction elements serve as intermediary components between bar elements, providing a standardized interface that simplifies the connection process while maintaining strength through the transition region design that enables centric force transfer
Solution Approach 2:
The junction elements are designed with universal applicability to connect various bar elements, standardizing the connection process and reducing complexity through repeated use of the same component type
3Force
If large solid components are used to transfer substantial forces in center boxes, then the force transfer capability is improved, but the production cost and repair expenditure increase
Solution Approach 1:
The center box structure is segmented into multiple bar elements connected by junction elements, replacing large solid components with smaller, more manageable elements that are easier to manufacture and replace if needed
Solution Approach 2:
The transition regions in junction elements provide localized quality enhancement where force concentration occurs, allowing the rest of the structure to use lighter, easier-to-manufacture components
4Stability of the object's composition
If ribs are used to transfer loads in center boxes, then local stiffening is achieved, but the weight increases and the shortest force path to fuselage connection is not utilized
Solution Approach 1:
The bar elements are arranged in optimized spatial configurations that utilize three-dimensional force paths, allowing loads to be transferred more directly to fuselage connections rather than following the two-dimensional rib patterns in traditional designs

AI summary
A support structure for an aircraft, includes one or several bar elements and one or several junction elements. At least one bar element includes a transition region which can be made to engage at least one junction element. When the transition region of the bar element engages at least one junction element, centric force transmission takes place between the bar element and the junction element.
