Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a fuel is detonated in the gas generator chamber to generate high pressure, then energy storage efficiency is improved, but the force acting on the generator chamber walls and valves increases excessively
Solution Approach 1:
A damping means (20) is arranged in the gas generator chamber (2) to dampen the sudden pressure increase during fuel explosion. The damping means includes a piston (18) that can move within the chamber, and a restoring means (20) such as a spring that is pre-tensioned to provide a damping effect before the explosion occurs, thereby reducing the peak force on chamber walls and valves while maintaining energy storage efficiency
2Stress or pressure
If explosive gases are released into the environment, then pressure build-up is achieved, but environmental harm and emissions occur
Solution Approach 1:
The system converts the harmful explosive gases generated during fuel detonation into a beneficial resource by channeling them through a valve assembly (17) into pressure accumulators (5, 7, 8) for energy storage. The explosive gases that would otherwise be harmful emissions are instead captured and stored as compressed energy, eliminating environmental harm while achieving the necessary pressure build-up for power generation
3Force
If a movable piston is added to dampen pressure increase, then force on chamber walls is reduced, but device complexity increases
Solution Approach 1:
The piston (18) and damping means (20) are designed to perform multiple functions: they dampen the sudden pressure increase during explosion, reduce peak force on chamber walls and valves, and can be integrated with the existing valve assembly (17) and pressure accumulator system. This multi-functionality minimizes the increase in device complexity while achieving the force reduction goal

AI summary
The invention relates to a storage power plant (1-1c), in particular a pressure storage power plant, which has a gas generator chamber (2-2b) and a pressure store device (6; 6b) which is fluidically connected to the gas generator chamber and which comprises at least one pressure store (5-5b, 7-7b, 8-8b; 8c), the generator chamber (2-2b) being designed to act as an explosion chamber in which an operating substance (3-3b) with which the storage power plant is operated is caused to explode. The at least one pressure store (5-5b, 7-7b, 8-8b; 8c) of the pressure store device (6; 6b) is expediently designed to receive an explosion gas (21) that is generated in the gas generator chamber (2-2b) as a result of the explosion of the operating substance (3-3b). A gas pressure generated in the explosion can advantageously be directly utilized, for example to operate the turbine for the purposes of generating electrical current. The invention also relates to a method for operating the storage power plant (1-1c).
