Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aircraft seat backrest frame units lack flexibility and versatility in design, limiting creative freedom for mounting and integrating functional units while compromising on stability and ease of assembly.
Innovation Solution
A multi-part backrest frame unit with separate side frame elements and a substantially plate-shaped transverse frame element, formed in one piece with a skeleton-like structure, provides high flexibility, stability, and versatility by allowing various functional units to be integrated and assembled efficiently, featuring integrally formed connection elements and a fastening unit for diverse mounting options.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional multi-part backrest frame units are used with separate side frame elements and transverse frame elements, then assembly is relatively simple, but flexibility and versatility in design are limited
Solution Approach 1:
The patent merges the transverse frame element with the side frame elements into a single integrated component. This unified structure combines the functions of multiple separate parts while maintaining assembly simplicity, thereby increasing design flexibility without proportionally increasing structural complexity.
Solution Approach 2:
The integrated frame unit is designed to serve multiple functions: providing structural support, enabling various mounting configurations for functional units, and accommodating different design requirements. This multi-functionality achieves high versatility without requiring multiple separate components.
2Adaptability or versatility
If more separate components are used in the backrest frame unit, then adaptability for mounting functional units increases, but assembly complexity and time increase
Solution Approach 1:
The frame unit is pre-integrated with connection elements and mounting features during manufacturing. This preliminary preparation allows functional units to be quickly attached without requiring complex on-site assembly operations, reducing assembly time while maintaining mounting flexibility.
Solution Approach 2:
While the frame itself is integrated, the design allows for segmented attachment of functional units through standardized connection points. This enables selective assembly of only the required functional units, optimizing assembly time based on specific application needs.
3Stability of the object's composition
If integrated frame structures are used to improve stability, then manufacturing complexity increases, but separate components are easier to manufacture
Solution Approach 1:
The patent optimizes manufacturing parameters such as material selection, thickness distribution, and connection element geometry to enable production of the integrated frame using standard manufacturing processes. This maintains manufacturing simplicity while achieving the required frame stability.
Solution Approach 2:
The frame may utilize composite materials or hybrid construction techniques that combine the ease of manufacturing separate components with the stability benefits of integration. This allows the integrated structure to be manufactured with the same simplicity as separate components while achieving superior structural stability.
