Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a measuring probe is installed inside the battery pack to directly monitor internal parameters, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The measuring probe is nested within the battery pack structure, with the probe installation part integrated into the pole plate. The probe piece is installed inside the probe installation part, creating a compact nested arrangement that enables internal monitoring without significantly increasing overall device complexity
Solution Approach 2:
The measuring probe is divided into distinct segments: the probe piece for measurement and the connecting part for electrical connection. This segmentation allows independent optimization of each component and simplifies installation and maintenance procedures
2Reliability
If a measuring probe is installed inside the battery pack to directly monitor internal parameters, then reliability is improved, but ease of manufacture deteriorates
Solution Approach 1:
The probe installation part is pre-formed on the pole plate during manufacturing, with the measuring port and probe installation structure integrated into the pole plate design. This preliminary action ensures proper positioning and sealing before the measuring probe is installed, improving both manufacturing efficiency and reliability
Solution Approach 2:
The measuring port and probe installation part are merged into a single integrated structure on the pole plate, eliminating separate components and reducing assembly steps. This merging simplifies the manufacturing process while ensuring reliable sealing and positioning
3Ease of operation
If the pole plate is provided with a measuring port and probe installation part, then ease of operation is improved, but manufacturing precision requirements increase
Solution Approach 1:
The pole plate is designed with localized features (measuring port and probe installation part) that have specific geometric requirements, while the rest of the pole plate maintains its standard structure. This local quality approach ensures precise positioning of measurement components without requiring high precision throughout the entire pole plate manufacturing process
