Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional internal combustion engines exhibit low efficiency, typically converting only about 20% of theoretical chemical energy from fuels into useful kinetic energy, and are often bulky, heavy, and require extensive internal lubrication.
Innovation Solution
The design incorporates a housing with torus-shaped combustion chambers and pistons, where pivot arms coupled to a guide frame with parallel guide columns allow pistons to move along a circular path, minimizing one combustion chamber volume and maximizing the other, sustained by an oblong plate at the common pivot point, optimizing energy transfer and reducing the need for internal lubrication.

Engineering Contradiction Analysis
1Use of energy by moving object
If conventional combustion engines are designed with cylindrical combustion chambers and pistons, then the engine structure is simple and easy to manufacture, but the engine efficiency is low (only about 20% of theoretical chemical energy is converted to useful kinetic energy)
Solution Approach 1:
The patent applies spheroidality by using toroidal (doughnut-shaped) combustion chambers instead of conventional cylindrical chambers, and toroidal pistons instead of conventional cylindrical pistons. This curved geometry allows for more efficient combustion patterns and better energy extraction, directly addressing the low engine efficiency problem while maintaining a relatively simple overall structure that can be manufactured using conventional techniques.
Solution Approach 2:
The patent segments the combustion chamber into two separate toroidal chambers, each with its own toroidal piston, operating in opposite directions. This segmentation allows for continuous power delivery and improved thermal efficiency by ensuring that while one chamber is expanding, the other is compressing, thereby improving engine efficiency without significantly increasing structural complexity.
2Power
If conventional combustion engines are designed to provide sufficient power output, then the engine can meet performance requirements, but the engine size and weight increase
Solution Approach 1:
The patent transitions from conventional linear piston motion to rotational-toroidal motion in three dimensions. The toroidal pistons move in a circular path within the toroidal chambers, utilizing rotational dynamics to generate power. This dimensional change allows for more compact engine design while maintaining or increasing power output, as the rotational motion provides continuous force application rather than intermittent linear pushes.
3Power
If conventional combustion engines are designed with moving piston components, then power generation is achieved, but the need for internal lubrication increases
Solution Approach 1:
The toroidal piston design with its continuous rotational motion and specific geometric configuration creates self-lubricating conditions through the motion itself. The curved paths and contact surfaces are designed to minimize friction and wear, allowing the engine components to service themselves through the inherent characteristics of the toroidal motion rather than requiring extensive external lubrication systems.
