Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If flexible circuit board and wiring harness are used for signal transmission, then signal collection can be achieved, but reliability deteriorates due to interference coupling and short-circuiting risks
Solution Approach 1:
The patent extracts and removes the flexible circuit board and wiring harness from the signal transmission path. Instead, it uses the battery housing itself as the signal transmission medium through integrated conductors, thereby eliminating the problematic components that caused interference and short-circuiting issues.
Solution Approach 2:
The patent merges the signal transmission function with the battery housing structure. The housing serves dual purposes: mechanical protection and electrical signal transmission. This integration eliminates separate signal transmission components and reduces overall system complexity.
2Reliability
If flexible circuit board and wiring harness are arranged for signal transmission, then signal collection is enabled, but cost increases due to additional components
Solution Approach 1:
The patent combines the signal transmission function with the existing battery housing, eliminating the need for separate flexible circuit boards and wiring harnesses. This integration reduces component count and manufacturing cost while improving reliability.
Solution Approach 2:
The battery housing is designed to serve multiple functions: mechanical protection of internal components and electrical signal transmission. This multi-functionality eliminates the need for dedicated signal transmission components, reducing overall system cost.
3Reliability
If conventional wiring method is used, then signal transmission can be achieved, but signal transmission path is long and prone to interference
Solution Approach 1:
The patent removes the lengthy flexible circuit board and wiring harness from the signal path. By using integrated conductors within the housing, it dramatically shortens the signal transmission path and eliminates the intermediate components that caused interference.

AI summary
A battery cell, a battery, and an electric apparatus are described. A sampling module is connected to a housing and electrically connected to a conductor. At least one conductor is disposed on the housing and electrically connected to an electrode terminal. When status signals from the battery cell are collected, signals from at least one collection point of the sampling module are directly transmitted by the electrode terminal. In this way, the sampling module is integrated on the end cover and at least one conductor is electrically connected to the electrode terminal, which changes the conventional method of transmitting signals to CMC through a flexible circuit board and wiring harness, avoids the transmission of status signals from being affected by factors such as interference coupling and wiring harness short-circuiting, shortens the signal transmission path, and improves the reliability of signal collection by the sampling module.
