Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the rechargeable battery is fixed to the power-assisted trolley, then the power supply is stable, but it is difficult to use the power-assisted trolley during charging of the rechargeable battery
Solution Approach 1:
The battery system is segmented into a fixed battery mount and a removable battery pack. The battery can be detached from the battery mounting portion, allowing users to replace depleted batteries with charged ones without waiting for charging completion, thus maintaining operational reliability while improving usability during charging cycles.
2Stability of the object's composition
If the rechargeable battery is fixed to the power-assisted trolley, then the battery is securely positioned, but it causes deterioration in convenience
Solution Approach 1:
The battery mounting system transitions from a static fixed connection to a dynamic removable connection. The battery can be securely positioned during operation through the battery mounting portion, yet can be easily removed and replaced when needed, providing both stability during use and convenience for battery replacement without charging delays.
