Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Thermodynamic cycle systems face high costs due to redundancy in electronic components and limited flexibility in using alternative components, along with electromagnetic interference issues from long supply lines.
Innovation Solution
Centralized supply electronics with integrated power electronics for each component minimize redundant components and reduce electromagnetic radiation by providing unmodulated DC supply voltages, allowing flexible adaptation to different power ranges without altering the central unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If each electronic component has its own decentralized electronic units with supply electronics and power electronics, then independent control of individual components is possible, but the system causes high costs due to redundancy of electronic components
Solution Approach 1:
The patent merges the supply electronics into a single centralized unit that serves all electronic components (EC compressor, EC fans, EC pump). This eliminates the redundancy of having separate supply electronics in each component, reducing overall system complexity and cost while maintaining the ability to independently control each component through dedicated control circuits within their respective units.
2Device complexity
If a central electronic unit operates all individual electronic components, then electronic components can be saved and production costs are reduced, but flexible use of alternative electronic components with other power ranges is not possible
Solution Approach 1:
The patent segments the electronic system into a centralized supply electronics unit and multiple independent electronic components, each with its own control circuit. This segmentation allows the central unit to provide power to multiple components while each component retains independent controllability, enabling flexible replacement with alternative components of different power ranges without modifying the central supply unit.
3Ease of operation
If the central electronic unit connects to individual electronic components via separate lines, then centralized control is achieved, but long lines produce unwanted electromagnetic radiation
Solution Approach 1:
The patent introduces control circuits as intermediary elements within each electronic component. These control circuits receive control signals from the centralized control unit and locally regulate the electronic components (EC compressor, EC fans, EC pump). This intermediary approach maintains centralized control capability while minimizing electromagnetic radiation by keeping the high-frequency power electronics localized within each component rather than using long separate lines from a central unit.
