Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesive material is applied to battery cells during assembly, then the battery cells can be stably located and heat can be dissipated, but the battery cells may be damaged during the adhesive application process
Solution Approach 1:
The patent applies preliminary action by measuring the profile of the battery cell coating surface before adhesive application. The sensor captures the actual surface geometry, and the controller pre-calculates the optimal discharger position and movement speed based on these measurements, preventing damage before it occurs during adhesive application.
Solution Approach 2:
The patent implements feedback by using a sensor to detect the actual profile of the battery cell coating surface, then feeding this information back to the controller. The controller adjusts the discharger's position and speed based on the detected profile, creating a closed-loop system that adapts to variations in battery cell geometry and prevents damage.
2Manufacturing precision
If adhesive material is uniformly applied to battery cells, then the battery assembly performance is improved, but the complexity of the manufacturing process increases
Solution Approach 1:
The patent applies self-service by enabling the manufacturing system to automatically measure its own working conditions (battery cell profiles) and self-adjust the discharger parameters accordingly. The sensor and controller work together to create an autonomous system that adapts to each battery cell's unique geometry without requiring manual intervention or complex external calibration equipment.
Solution Approach 2:
The patent implements parameter changes by dynamically adjusting the discharger's position and movement speed based on the detected battery cell profile. Rather than using a fixed, complex mechanical system, the invention changes operational parameters (position coordinates and speed) in real-time based on sensor feedback, achieving uniform adhesive application through software control rather than mechanical complexity.
