Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If surface treatment is applied only to the connection portion of the sampling wire, then the treatment process complexity increases due to structural limitation, but the sampling wire can acquire temperature signals
Solution Approach 1:
The sampling wire is divided into two distinct segments: the connection portion remains bare metal for optimal electrical contact, while the body portion is coated with a protective layer for oxidation resistance. This segmentation allows each portion to have optimized properties for its specific function without compromising the other.
Solution Approach 2:
Different portions of the sampling wire are given different surface qualities: the connection portion maintains bare metal surface for electrical conductivity and weldability, while the body portion receives a protective coating for corrosion and oxidation resistance. This local differentiation resolves the contradiction by applying treatment only where needed rather than uniformly across the entire wire.
2Adaptability or versatility
If the sampling device has a complex structural composition, then it can acquire multiple working parameters, but the installation becomes inconvenient and production efficiency decreases
Solution Approach 1:
The sampling wire structure is designed to perform multiple functions: it serves as both an electrical connection element and a temperature sensing element, while also providing mechanical support and protection through its coated structure. This multi-functionality eliminates the need for separate dedicated components for each function, simplifying the overall device structure while maintaining the capability to acquire multiple working parameters.
Solution Approach 2:
The sampling wire combines multiple functions into a single integrated component: electrical signal transmission, temperature signal acquisition, and structural support. By merging these functions into one element rather than using separate components, the device structure is simplified and installation becomes more convenient while still achieving versatile parameter acquisition.

AI summary
The present application provides a sampling device, a battery and a power consuming apparatus. The sampling device includes a sampling circuit board. The sampling circuit board has a first sampling wire and a second sampling wire. The first sampling wire and the second sampling wire are configured to acquire different working parameters of a battery module. A continuous or discontinuous protective layer is provided on a surface of at least one of the first sampling wire and the second sampling wire, and the first sampling wire and the second sampling wire are both connected to a signal output portion provided on the sampling circuit board. In the present application, the way of surface treatment for the entire sampling line is not limited by the structure of a connection portion, thereby avoiding the problem of an increased complexity of a treatment process due to the structural limitation of the connection portion.
