Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle engines without digital engine control systems face challenges in retrofitting to digital control due to inherent differences between digital and analog control systems, particularly in applications with strict safety, reliability, and weight restrictions, such as aviation.
Innovation Solution
The development of engine management modules (EMMs) that convert linear or rotational inputs into multiple rotational and/or linear outputs, enabling universal vehicle control interfaces to operate various vehicles using a single set of inputs, decoupling axes of movement, and utilizing models specific to each vehicle phase for efficient integration and control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If analog control systems are used in vehicles without digital engine control, then the vehicle can operate with simpler control architecture, but it becomes difficult to retrofit digital control due to inherent differences between digital and analog control systems
Solution Approach 1:
The patent introduces an intermediary device that acts as a bridge between digital control systems and analog engine control systems. This intermediary converts digital control signals into analog mechanical movements, enabling digital control retrofit in vehicles with analog engine control without requiring complete system replacement, thus resolving the adaptability issue while managing complexity.
2Ease of operation
If multiple vehicle-specific control interfaces are maintained, then each vehicle can have optimized control, but it increases the need for customizations and reconfigurations
Solution Approach 1:
The patent creates a universal control interface that can accommodate multiple vehicle types and control scenarios through a single standardized mechanism. This universal interface design allows the same control system to work across different vehicles without requiring vehicle-specific customizations, thereby improving ease of operation and manufacturing while maintaining adaptability through configurable parameters.
3Extent of automation
If manual control operations are required, then direct operator control is achieved, but it reduces hands-free operation capability and increases operator workload
Solution Approach 1:
The patent implements feedback mechanisms that provide the operator with tactile or visual confirmation of control system status and engine response. This feedback loop enables hands-free or reduced-hand operation by allowing the system to self-adjust based on sensor data while keeping the operator informed, thus increasing automation extent without sacrificing operator control awareness or directness when needed.

AI summary
Some embodiments relate to a device (e.g., an engine management module) that includes a sled coupled to a base, the sled configured to translate along a sled axis. The device further includes a guide plate coupled to the sled, where the first guide plate includes a first channel. The device further includes a lever coupled to a shaft that is fixed to the base. The first lever has a first end and a second end. The first end includes a first guide pin that is positioned within the first channel such that as the sled translates along the sled axis, the first guide pin moves along the first channel to cause the second end of the first lever to rotate about the shaft.
