Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional internal combustion engines face limitations in scalability and motion control, particularly in alternative designs where piston movement is controlled by cam surfaces, as they often require complex configurations and are not easily adaptable to varying engine capacities.
Innovation Solution
The design incorporates a piston arrangement coupled to a track with inner and outer cam surfaces, where followers on a sliding element control the piston's motion, allowing for scalable engine architecture with interchangeable components and enhanced cooling capabilities, and includes a method for assembling the engine by coupling the piston arrangement to a shaft and end plates to facilitate easy construction and adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional cam surface designs are used to control piston movement, then motion control is achieved, but device complexity increases and scalability is limited
Solution Approach 1:
The engine is divided into modular components: interchangeable plates, end plates, tracks, and piston assemblies. Each plate can be independently configured and replaced to achieve different engine capacities, reducing overall system complexity while maintaining effective motion control through standardized cam surface interfaces.
Solution Approach 2:
The plates are designed with universal features that allow them to serve multiple functions: structural support, cam surface provision, and scalability through interchangeability. The same plate design can be used across different engine configurations, simplifying the design process while maintaining effective piston motion control.
2Power
If engine capacity is increased in conventional designs, then power output improves, but device complexity and component variety increase
Solution Approach 1:
The engine capacity can be scaled by simply adding or removing track-piston assemblies from the modular plate structure, rather than redesigning entire components. This segmentation allows power output to be adjusted while maintaining the same set of standardized plates, reducing component variety.
Solution Approach 2:
Engine capacity is adjusted by changing the number of active tracks and pistons rather than modifying the fundamental plate geometry or cam surface profiles. This parameter change approach allows scalable power output while reusing the same component library.
3Adaptability or versatility
If complex configurations are used to achieve scalability, then engine capacity can be adjusted, but ease of manufacture decreases
Solution Approach 1:
The engine is constructed from discrete, pre-manufactured plates and track-piston assemblies that can be independently produced and then simply assembled together. This segmentation enables complex scalability without increasing manufacturing complexity, as each module can be made using standardized processes.
Solution Approach 2:
The plates are designed to be substantially identical or mirror images, allowing them to be manufactured using the same processes and then assembled in different configurations. This homogeneity simplifies manufacturing while maintaining adaptability for different engine capacities.
