Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complex and labor-intensive process of attaching wall modules to the aircraft fuselage, which is exacerbated by the lightweight construction and need for precise alignment, necessitates a simpler and more efficient fastening method to facilitate automated assembly and disassembly.
Innovation Solution
A holding device utilizing two clamping devices, one with a pivot-mounted clamping jaw and an actuating lever, and a second fork-shaped clamping device, to securely attach wall modules at their top and bottom edges, allowing for initial placement without additional securing points, with optional additional fasteners for further stabilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple screwing processes are used at numerous fastening points to attach wall modules, then the attachment reliability is improved, but the installation time and labor intensity increase significantly
Solution Approach 1:
The attachment system is segmented into two distinct clamping devices: a first clamping device for initial rough alignment and a second clamping device for fine adjustment and final securing. This segmentation allows each device to specialize in a specific function, reducing the overall complexity and time of the attachment process while maintaining reliability through the coordinated action of both devices.
Solution Approach 2:
The first clamping device performs preliminary rough alignment of the wall module before the second clamping device is engaged for fine adjustment. This preliminary action establishes the basic position and orientation of the wall module, reducing the adjustment range needed by the second device and thereby reducing total installation time.
2Reliability
If multiple screwing processes are used at numerous fastening points, then the attachment reliability is improved, but the device complexity increases
Solution Approach 1:
The complex fastening process is divided into two distinct clamping devices with specialized functions. The first device handles rough alignment with simpler mechanics, while the second device handles fine adjustment and final securing. This segmentation reduces the complexity of each individual device compared to a single multi-functional fastening system.
Solution Approach 2:
The second clamping device incorporates a movable clamping jaw that can be adjusted dynamically to achieve fine alignment adjustments. This dynamic capability allows the device to adapt to position deviations without requiring complex pre-adjustment mechanisms, simplifying the overall fastening process.
3Weight of moving object
If lightweight construction materials are used for wall modules, then the weight is reduced, but the attachment and anchoring becomes more complex
Solution Approach 1:
The first clamping device performs preliminary rough alignment and temporary securing of the lightweight wall module before the second clamping device is engaged. This preliminary action prevents the lightweight module from shifting during the attachment process, making the subsequent fine adjustment and final securing simpler and more reliable.
Solution Approach 2:
The alignment and securing functions are extracted from a single complex fastening process and assigned to two separate clamping devices. The first device extracts the rough alignment function, while the second device extracts the fine adjustment and final securing function. This extraction simplifies each individual device and the overall attachment process.
4Manufacturing precision
If precise alignment is required for wall module attachment, then the manufacturing precision is improved, but the installation time increases
Solution Approach 1:
The alignment process is segmented into two stages: rough alignment by the first clamping device and fine adjustment by the second clamping device. This segmentation allows each device to focus on a specific precision level, achieving high overall precision without requiring either device to perform the entire alignment sequence, which would be time-consuming.
Solution Approach 2:
The second clamping device employs a movable clamping jaw that can be dynamically adjusted to achieve precise alignment. This dynamic adjustment capability enables fine-tuning of the wall module position after the first device has established rough alignment, achieving high precision efficiently without requiring time-consuming manual adjustments.

AI summary
A holding device for a wall module 10 of the cabin lining in an aircraft comprises two different clamping devices. The first clamping device 30 includes a clamping body 33 with a first clamping jaw 31, fixed relative to the clamping body, and a second clamping jaw 32, movable relative to the clamping body 33, which in turn is operatively connected to an actuating lever 35 or can be temporarily connected. In the "closed" state, the clamping jaws 31 and 32 form a receiving space 36 for the wall module 10. A locking mechanism 37 fixes the position of the clamping jaws 31 and 32 relative to each other in the "closed" state.
