Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a battery is replaced by stopping the system and powering off, then the battery can be safely separated and mounted, but the system operation is interrupted and time is lost
Solution Approach 1:
The patent applies preliminary action by pre-positioning a charged battery pack adjacent to the operating system before battery replacement is needed. The pushing protrusion on the new battery pack is designed to automatically engage and push the locking protrusions of the old battery pack outward, initiating the unlocking sequence before the old battery is fully removed. This preliminary positioning and pre-configured mechanical interaction enable seamless replacement without system shutdown.
Solution Approach 2:
The patent achieves continuity of useful action through overlapping electrical contacts. The power terminal with its anode and cathode extends beyond the battery pack boundaries, creating a transition zone where electrical connection is maintained during battery replacement. The diodes ensure continuous power flow from either battery pack to the system, eliminating interruptions and maintaining uninterrupted operation throughout the battery swap process.
2Stability of the object's composition
If locking protrusions are used to secure the battery pack, then the battery is firmly fixed in the seat, but the locking mechanism adds device complexity
Solution Approach 1:
The patent applies segmentation by dividing the locking function into separate, independent locking protrusions on the battery pack that correspond to locking grooves on the seat. Each locking protrusion can move independently along its designated path, allowing individual engagement and disengagement. This segmentation simplifies the overall locking mechanism while maintaining secure fixation, as each protrusion-groove pair operates autonomously without requiring complex coordinated movement.
Solution Approach 2:
The patent applies inversion by reversing the traditional locking approach. Instead of the seat actively gripping or clamping the battery pack, the battery pack's locking protrusions actively engage with the seat's locking grooves. The new battery pack uses its pushing protrusion to initiate the unlocking action by pushing the old battery pack's locking protrusions outward, inverting the control relationship and simplifying the mechanism while maintaining secure fixation.
3Reliability
If power terminals are extended beyond battery pack boundaries, then seamless power transfer is enabled, but the battery pack design becomes more complex
Solution Approach 1:
The patent applies universality by designing the power terminal to serve multiple functions simultaneously. The extended power terminal with its anode and cathode not only provides electrical connection but also creates a physical guide for battery pack alignment. The terminal structure acts as both an electrical conductor and a mechanical interface element, reducing the need for separate alignment features and simplifying the overall connection system while ensuring continuous power supply during replacement.

AI summary
There is provided a non-stop battery changing system that includes: a body connected to a moving body that is moved by power, having a seat on a side, and having locking grooves and a power terminal in the seat; a battery pack inserted in the seat of the body to supply power to the moving body, having locking protrusions sliding inward/outward, and having a battery terminal that comes in contact with the power terminal; and a pushing protrusion extending outward from a side of the battery pack in a mounting direction of the battery pack inserted in the seat by movement of the moving body, and unlocking the locking protrusions out of the locking grooves, when the battery pack used in the seat is replaced with another charged battery pack.
