Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional rudder bar with numerous components and connections is used, then the steering and braking functions are achieved, but the device complexity increases and maintenance becomes difficult
Solution Approach 1:
The rudder bar system is divided into independent pedal modules that can be separately manufactured, tested, and replaced. Each pedal module is a self-contained unit with integrated components, allowing modular maintenance without disassembling the entire rudder bar system.
Solution Approach 2:
Multiple functions (steering control, braking, position sensing, adjustment mechanisms) are merged into a single integrated pedal module. This consolidation reduces the overall number of separate components and connections while maintaining all necessary functions.
2Reliability
If a conventional rudder bar with numerous components is used, then the steering and braking functions are achieved, but the mass and spatial requirements increase
Solution Approach 1:
Multiple functional components are merged into a single integrated pedal module, eliminating the need for separate mounting structures, connections, and support elements that would increase mass. The consolidated design reduces material usage while maintaining structural integrity.
Solution Approach 2:
The pedal module is designed as a multi-functional unit that performs steering control, braking, position sensing, and adjustment functions within a single structure. This multi-functionality eliminates redundant components that would otherwise be needed for each separate function, reducing overall mass.
3Reliability
If a conventional rudder bar with numerous connections is used, then the steering and braking functions are achieved, but the ease of repair deteriorates
Solution Approach 1:
The rudder bar system is segmented into independent pedal modules that can be easily removed and replaced as complete units. This segmentation eliminates the need for complex disassembly of multiple connections and allows rapid replacement of faulty modules without affecting other parts of the system.
Solution Approach 2:
The pedal modules are extracted as separate, self-contained units from the rudder bar structure. This extraction allows the modules to be maintained, tested, and replaced independently, significantly simplifying repair operations compared to integrated conventional designs.
4Reliability
If a conventional rudder bar with fixed pedal angles is used, then the basic functions are achieved, but the adaptability to different pilots deteriorates
Solution Approach 1:
The pedal module incorporates adjustable components that allow the pedal angle and position to be dynamically modified according to different pilot requirements. This adjustability transforms a static, one-size-fits-all design into a dynamic system that adapts to various ergonomic needs while maintaining reliable basic functions.
