Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a mechanical device is used to apply adhesive material, then the coupling of battery cells and case can be achieved, but the accuracy and flexibility of adhesive dispensing is insufficient
Solution Approach 1:
The patent replaces traditional mechanical dispensing devices with a robot module that uses vision guidance and control algorithms to achieve precise adhesive dispensing. The robot module integrates vision module feedback with automated control, substituting simple mechanical operation with an intelligent system that achieves higher precision while maintaining manageable complexity through software control.
Solution Approach 2:
The vision module creates a digital representation (image) of the workpiece, and the control module uses this copied visual information to guide the robot module for accurate adhesive dispensing. This copying approach allows the system to achieve high precision by referencing the visual map rather than relying solely on mechanical positioning accuracy.
2Strength
If adhesive material is applied to ensure stable coupling of battery cells and case, then the coupling strength is improved, but the flexibility in adjusting adhesive patterns is limited
Solution Approach 1:
The system dynamically adjusts adhesive dispensing parameters including pattern, amount, and position based on real-time vision feedback and user-defined requirements. The robot module can adapt its motion path and the dispenser module can adjust fluid output dynamically, allowing the same system to handle various coupling strength requirements and adhesive patterns flexibly while maintaining stable coupling.
Solution Approach 2:
The control module enables flexible adjustment of multiple dispensing parameters including adhesive amount, dispensing speed, nozzle position, and pattern geometry. By allowing independent modification of these parameters, the system can optimize both coupling strength and adhesive pattern flexibility for different application requirements without compromising either objective.
3Manufacturing precision
If precise movement of nozzle is achieved for accurate dispensing, then the dispensing accuracy is improved, but the system complexity increases
Solution Approach 1:
The vision module serves as an intermediary that simplifies the control problem by providing visual feedback about the workpiece position and orientation. This visual information acts as a mediator between the robot module's motion control and the actual dispensing accuracy, allowing the system to achieve high precision through vision-guided adjustment rather than requiring extremely complex mechanical positioning systems.
Solution Approach 2:
The system implements closed-loop feedback where the vision module continuously monitors the workpiece and the control module adjusts the robot module's nozzle position in real-time based on this feedback. This feedback mechanism enables accurate dispensing by compensating for positioning errors dynamically, reducing the need for overly complex mechanical precision mechanisms.
4Stability of the object's composition
If pressure control of viscous fluid is implemented, then the fluid dispensing consistency is improved, but the control system complexity increases
Solution Approach 1:
The dispenser module incorporates self-regulating pressure control mechanisms that automatically maintain consistent fluid dispensing. The system uses built-in pressure sensors and control algorithms that enable the dispenser to self-adjust and maintain stable viscous fluid output without requiring complex external pressure control systems, achieving fluid consistency through autonomous regulation.
