Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the battery is disassembled to perform X-ray spectroscopic analysis, then the analysis can be performed on battery materials, but the analysis process becomes troublesome and cannot analyze continuous changes during charging and discharging
Solution Approach 1:
The holder is divided into distinct functional components: a body portion, a window portion with X-ray permeability, and electrode terminals. This segmentation allows the battery to remain intact while enabling X-ray analysis through the window, resolving the contradiction between maintaining battery integrity and enabling analysis capability.
Solution Approach 2:
The window portion acts as an intermediary element that allows X-rays to pass through while maintaining the battery's sealed structure. This mediator enables X-ray spectroscopic analysis without requiring battery disassembly, thus preserving both the battery's integrity and the analysis capability.
2Reliability
If the battery casing is made of metal with low X-ray permeability for protection, then the battery is protected, but X-ray analysis of internal electrodes becomes difficult
Solution Approach 1:
The holder is designed with non-uniform X-ray permeability: the window portion has high X-ray permeability to enable analysis, while the body portion maintains metal construction for protection. This local differentiation of material properties resolves the contradiction between protection and analysis capability.
Solution Approach 2:
The holder combines metal materials (for protection and structural integrity) with X-ray permeable materials (for analysis access) in a composite structure. This material combination allows simultaneous achievement of battery protection and X-ray analysis capability.
3Duration of action of moving object
If the battery is kept assembled for continuous monitoring, then continuous changes during charging and discharging can be analyzed, but the battery structure blocks X-ray penetration
Solution Approach 1:
The holder's window portion is specifically designed as a separate segment with high X-ray permeability, allowing continuous X-ray analysis during battery operation without requiring disassembly, thus enabling long-term continuous monitoring.
Solution Approach 2:
The holder design enables continuous X-ray spectroscopic analysis during battery charging and discharging cycles through the window portion, maintaining uninterrupted measurement capability throughout the battery's operational life.
