Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a rotary combustion engine is designed with a rotor rotating around an eccentric shaft with sealing plates sliding radially, then the engine can achieve continuous combustion and rotational motion, but the fuel efficiency remains poor compared to diesel or petrol engines
Solution Approach 1:
The housing plate is made axially displaceable and equipped with spring biasing, allowing it to dynamically adjust its position to optimize combustion chamber volume during the combustion cycle. This dynamic adjustment enables better expansion ratios and more complete combustion, directly improving fuel efficiency while maintaining reliable operation
Solution Approach 2:
The invention changes the geometric parameters of the combustion chamber by allowing axial displacement of the housing plate. This enables optimization of the compression ratio and expansion ratio, which are critical parameters for improving combustion efficiency and fuel utilization in rotary engine configurations
2Reliability
If the first housing plate is made axially displaceable to enable expansion of the closed chamber, then the combustion efficiency is improved, but the mechanical complexity and potential maintenance needs increase
Solution Approach 1:
Spring biasing elements are pre-installed on the axially displaceable housing plate to provide automatic cushioning and controlled movement. This beforehand cushioning mechanism guides the housing plate's axial displacement, ensuring smooth operation and reducing mechanical stress, thereby improving combustion efficiency without proportionally increasing maintenance complexity
Solution Approach 2:
The spring-biased axially displaceable housing plate creates a self-regulating combustion chamber expansion mechanism. The spring automatically adjusts the housing plate position based on combustion pressure, enabling the system to self-optimize combustion efficiency without complex external control mechanisms

Implementation Method 1
the first housing plate is biased against the cylindrical housing so as to be axially displaceable along the longitudinal axis
Implementation Method 2
molecular hydrogen can react with molecular oxygen, also referred to as oxygen gas, (O 2 ), which is abundant in the air, in an exothermic reaction that produces water (H 2 O) as the only residual product
