Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual placement of battery in battery accommodating groove is used, then operation simplicity is maintained, but positioning accuracy of battery to set position deteriorates
Solution Approach 1:
The battery automatically positions itself using gravity to slide into the battery accommodating groove, eliminating the need for manual positioning operations while achieving accurate placement at the set position
Solution Approach 2:
The battery accommodating groove is designed with a specific slope angle that creates a gravitational force component along the groove, enabling the battery to naturally slide to the correct position without external intervention
2Manufacturing precision
If position adjustment mechanism is added to improve positioning accuracy, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The system uses the battery's own weight and gravity to achieve positioning, eliminating the need for complex external adjustment mechanisms. The battery automatically slides to the correct position when placed in the grooved structure
Solution Approach 2:
The battery accommodating groove acts as an intermediary structure that guides and positions the battery using its geometric shape and slope, replacing the need for active adjustment mechanisms
3Manufacturing precision
If automatic detection and position correction is implemented, then butting accuracy to liquid injection port is improved, but productivity is reduced due to additional operations
Solution Approach 1:
The battery is pre-positioned in the accommodating groove with built-in positioning features that ensure correct alignment before the liquid injection operation, eliminating the need for post-placement detection and adjustment
Solution Approach 2:
The battery's own geometric features and the groove structure work together to automatically ensure correct positioning, making detection and correction operations unnecessary

AI summary
A liquid injection device comprises a liquid injection apparatus comprising: a battery clamp provided with at least one battery accommodating groove having a set position therein, a position adjustment mechanism configured to be capable of adjusting a battery that has been put in the battery accommodating groove and not located at the set position to the set position, and a liquid injection mechanism configured to be capable of butting to a liquid injection port of the battery located at the set position, and performing a liquid injection operation of injecting an electrolyte into the battery. For a battery that is not located at the set position, position adjustment is performed with the position adjustment mechanism such that the battery moves to the set position.
