Beam Fixing Assembly With Angled Clamping for Perpendicular Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beam fixation systems in aircraft propulsion assemblies restrict the orientation of beams, preventing them from being positioned perpendicular to the former, which limits flexibility and space utilization.
Innovation Solution
An assembly that includes a support plate with parallel faces, a first fixing with a stud and sleeves, and a second fixing with a housing and clamping screw, allowing the clamping screw to be angled relative to the bearing plane between 10° and 80°, enabling beams to be positioned perpendicular to the support plate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If beams are fixed using conventional fixings with perpendicular screws to the former, then the fixation structure is simple and robust, but the beams cannot be positioned perpendicular to the former, limiting orientation freedom
Solution Approach 1:
The invention introduces an angled clamping screw that operates in a different dimensional orientation relative to the support plate. The screw axis is angled between 10° and 80° to the bearing plane, allowing the beam to be clamped perpendicular to the former while the screw itself approaches from an angled direction, thus freeing up the perpendicular position for the beam
Solution Approach 2:
The invention introduces an intermediary clamping screw that mediates between the support plate and the beam. This screw acts as a mediator that transfers clamping force from an angled approach to achieve perpendicular beam positioning, enabling the beam to be oriented perpendicular to the former without the screw being perpendicular to the support plate
2Ease of operation
If the clamping screw is positioned perpendicular to the support plate, then the fixation is straightforward, but the beam cannot be positioned perpendicular to the former, reducing spatial efficiency
Solution Approach 1:
The clamping screw operates from an angled dimension rather than a perpendicular one, allowing the beam to occupy the perpendicular space relative to the former. This dimensional repositioning enables both simple angled screw insertion and optimal perpendicular beam placement for space efficiency
3Productivity
If conventional perpendicular fixing is used, then the assembly process is simple, but beam orientation is restricted, limiting design flexibility
Solution Approach 1:
By changing the screw approach angle to between 10° and 80° relative to the bearing plane, the invention enables perpendicular beam positioning while maintaining straightforward assembly. The angled approach simplifies the path for inserting and tightening the clamping screw compared to trying to install a perpendicular screw through constrained spaces

AI summary
An assembly including a support plate through which passes an opening with two faces parallel to a bearing plane, a first fixing fixed against the first face, first sleeves receiving beams, and a stud with a hole having an axis, a second fixing against the second face, second sleeves receiving beams, a housing for the stud and a clamping screw screwed into the hole, with the axis at an angle (α) to the bearing plane between 10° and 80° inclusive. The assembly forms a chassis which may be fixed to a propulsion assembly and a wing of an aircraft.
