Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Internal combustion engines face inefficiencies in converting combustion forces into mechanical energy due to limitations in design and material usage, particularly in high-temperature environments, which affect the durability and energy output.
Innovation Solution
A combustion engine design featuring an engine block with a combustion generating system, crankshaft, leading and trailing blades, and exhaust ports, where the inner block surface is complementarily shaped to the blades to form a combustion chamber, allowing for efficient ignition and rotation of the crankshaft via a combustion force, using materials like metal, ceramic, or steel that can withstand high temperatures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional materials are used in the combustion engine, then manufacturing cost is reduced, but the engine cannot withstand high temperatures and maintain durability
Solution Approach 1:
The patent applies composite materials by combining metal components (crankshaft, blades) with ceramic coatings or ceramic-matrix composite materials. This composite approach allows the engine to withstand high temperatures while maintaining structural integrity and durability, directly resolving the contradiction between temperature resistance and material reliability
2Productivity
If the combustion chamber is designed with complementarily shaped blades, then energy conversion efficiency is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent employs curved and arced blade edges instead of straight edges, creating complementarily shaped surfaces that efficiently direct combustion forces. The curved geometry of the blades and combustion chamber optimizes energy conversion while the design accommodates reasonable manufacturing tolerances through its geometric form
3Power
If the combustion force is positioned closer to one blade wall, then mechanical motion efficiency is improved, but stress concentration increases
Solution Approach 1:
The patent deliberately positions the combustion force asymmetrically closer to one blade wall rather than at the center. This asymmetric positioning optimizes the mechanical motion efficiency by creating more effective leverage on the crankshaft, while the overall symmetric structure of the combustion chamber distributes stress appropriately
Solution Approach 2:
The curved blade walls and combustion chamber geometry help distribute stress more evenly throughout the structure, mitigating stress concentration effects while maintaining the asymmetric combustion force positioning for optimal power output

Function Achieved in This Case
This design enhances energy conversion efficiency and durability by maintaining high tensile strength and withstanding high temperatures, enabling effective mechanical motion and energy production in various environments such as motor vehicles and marine vessels.
Implementation Method 1
The combustion generating system can supply and ignite an amount of air fuel composition at the location within the combustion chamber via the combustion port to create a combustion force
Implementation Method 2
The combustion force can force either the leading blade or the trailing blade wall to rotate away from the combustion force, which can rotate the crankshaft around the axis

AI summary
A combustion engine can include an engine block having interior and exterior block surfaces and a combustion generating system connected thereto, with the inner block surface defining a cavity therein; an exhaust port between the inner and exterior block surfaces; a crankshaft rotatably fixed within the cavity and configured to rotate around an axis; and leading and trailing blades connected to the crankshaft. During a combustion event, the inner block surface is complementarily shaped to the leading and trailing blades, such that the inner block surface is outside the blades' ranges of travel. A combustion generating system can supply and ignite an air fuel composition to create a combustion force positioned closer to one of the blades, forcing the one of the blades to rotate away from the combustion force, which rotates the crankshaft around the axis.
