Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If high-grade metallic material (nickel and titanium) is used for cell casing to provide dimensional stability, then the cell structure is stable and reliable, but the material cost and weight increase substantially
Solution Approach 1:
The patent replaces rigid thick-walled metallic casings with flexible thin metal foil sheets. These thin foils are sufficient for electrical conductivity and chamber definition, while the cell rack provides the necessary dimensional stability and mechanical support. This dramatically reduces material usage and weight.
Solution Approach 2:
The cell rack serves as an intermediary structure that assumes the dimensional stability function previously required in the cell casing itself. The cell casing is simplified to just define chambers and provide electrical conductivity, while the cell rack mediates the mechanical support and structural stability.
2Strength
If high-grade metallic material is used for cell casing to ensure structural strength, then the cell can support its own weight in operating conditions, but the material cost increases considerably
Solution Approach 1:
Thin metal foil sheets are used instead of thick rigid walls. The foils provide sufficient electrical conductivity and chamber definition with minimal material quantity. The cell rack compensates for the reduced structural strength by providing external mechanical support.
Solution Approach 2:
The structural support function is segmented from the cell casing. The cell casing is divided into minimal necessary components (thin foils for electrical and sealing functions), while the cell rack assumes the structural support function, allowing optimization of each component for its specific purpose.
3Reliability
If bolts and frame bars are used for sealing the cell casing, then the sealing is reliable, but the weight and device complexity increase
Solution Approach 1:
The mechanical sealing system (bolts, frame bars, gaskets) is replaced with an adhesive bonding system. The adhesive bond provides reliable sealing between the thin metal foil sheets, eliminating the need for complex mechanical fastening structures and reducing overall device complexity.
