Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If heat is removed from the working fluid in a cooling tower or natural body of water, then the working fluid can be condensed, but the process becomes complex and efficiency is reduced

Engineering Contradiction:
Improveheat removal efficiencyVSAvoidcondensation system complexity
Core Design Contradiction:
Loss of energyVSDevice complexity

Solution Approach 1:

The invention extracts the heat removal function from the system by using a large expansion tank where heat is naturally dissipated to the ambient environment, eliminating the need for complex cooling towers or water bodies while maintaining condensation capability

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The system uses the ambient environment to naturally absorb heat from the working fluid through the large expansion tank surface area, allowing the system to self-regulate condensation without active cooling mechanisms

Inventive Principle:
Principle #25Self-service

2Loss of energy

If the expansion tank is dimensioned large enough to enable condensation by Joule-Thomson effect, then heat removal is unnecessary and efficiency increases, but the tank size and system volume increase

Engineering Contradiction:

Core Design Contradiction:
Loss of energyVSVolume of stationary object

Solution Approach 1:

The invention changes the volume parameter of the expansion tank to be sufficiently large to enable natural heat dissipation and Joule-Thomson condensation, accepting the increased size as a trade-off for eliminating complex heat removal systems and improving overall efficiency

Inventive Principle:

Solution Approach 1:

The invention implements periodic delivery of working fluid based on level sensors that trigger delivery only when liquid levels reach specific thresholds, converting continuous operation into periodic cycles that reduce power consumption and wear while maintaining reliable system operation

Inventive Principle:
Principle #19Periodic action

AI summary

The invention relates to a fluid energy machine comprising a working fluid, an evaporator (10) in which the working fluid can be converted from its liquid state to its gaseous state by supplying heat, a substantially adiabatic expansion vessel (6), at least one piston engine (84, 85) with a piston (14, 15) by means of which the energy of the working fluid can be converted into mechanical energy and which has at least one cylinder chamber (37, 39) bounded by the piston, which during operation of the fluid energy machine is alternately fluid-conducting connected to the evaporator, whereby the cylinder chamber enlarges by moving the piston, and to the expansion vessel, whereby the cylinder chamber shrinks by moving the piston, a storage vessel (9) which is fluid-conducting connected to the evaporator and to the expansion vessel, and a conveying device (8).which is set up to convey the working fluid from the expansion vessel to the storage vessel, wherein the expansion vessel is dimensioned in relation to the cylinder chamber such that the working fluid can be condensed by the expansion of the gaseous fluid in the expansion vessel, and in the storage vessel the working fluid is present in both its gaseous and its liquid state, so that if the working fluid does not condense in the expansion vessel, it can be condensed in the storage vessel, and the working fluid can be conveyed to the evaporator.
