Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If thermoelectric elements are arranged in series, then the voltage output is improved, but the output current is limited and the space requirement increases
Solution Approach 1:
The patent divides the thermoelectric power generation system into multiple independent thermoelectric elements (first and second thermoelectric elements) that can be arranged in parallel. Each element consists of separate thermoelectric conversion layers and electrolyte layers, allowing independent current generation while maintaining modular structure for efficient space utilization.
Solution Approach 2:
The patent transitions from traditional series arrangement to a parallel arrangement of multiple thermoelectric elements stacked in the vertical dimension. The first and second thermoelectric elements are stacked with current collectors positioned between them, enabling parallel current paths that increase output current while maintaining compact vertical footprint.
2Productivity
If multiple thermoelectric elements are stacked to increase output current, then the output current is improved, but the device complexity increases
Solution Approach 1:
The patent merges the current collection function into the stacked structure by positioning current collectors between the first and second thermoelectric elements. The current collectors serve as both electrical connection points and structural separators, integrating multiple functions into a single component arrangement that reduces overall structural complexity.
Solution Approach 2:
The current collectors in the patent serve multiple functions: they collect current from thermoelectric elements, provide electrical connection between parallel elements, act as structural separators in the stacked arrangement, and facilitate thermal management. This multi-functionality reduces the need for additional components and simplifies the overall device structure.
3Manufacturing precision
If separate electrolyte layers and thermoelectric conversion layers are used for each element, then the manufacturing precision is improved, but the manufacturing cost increases
Solution Approach 1:
The patent combines the electrolyte layers and thermoelectric conversion layers into integrated assemblies that are manufactured as unified structures. The first and second thermoelectric elements are constructed with their respective electrolyte and conversion layers already integrated, allowing for precise alignment during assembly while reducing the number of separate manufacturing steps and component assembly operations.
