Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If traditional battery swap devices are used, then battery charging function is provided, but device space occupied is large and structure is complicated
Solution Approach 1:
The charging device is divided into independent modules: first bracket, second bracket, charging terminal unit, and driving unit. Each module performs a specific function and can be independently manufactured and assembled, reducing overall system complexity while maintaining compact dimensions.
Solution Approach 2:
The charging terminal unit is nested between the first and second brackets, with the second bracket movable relative to the first. The connector is nested within the charging terminal unit structure, allowing multiple components to occupy overlapping spatial volumes and minimizing the overall device footprint.
2Reliability
If fixed connector positioning is used, then structural simplicity is maintained, but engagement reliability is poor due to positioning errors
Solution Approach 1:
The second bracket is designed to move horizontally relative to the first bracket, transforming the rigid fixed-position connector into a dynamic adjustable connector. This movement capability allows the connector to adapt to positioning errors and maintain reliable engagement without requiring overly complex adjustment mechanisms.
Solution Approach 2:
The horizontal position parameter of the second bracket is changed to enable the connector to adjust its location. By varying this positional parameter, the system compensates for manufacturing tolerances and positioning errors, improving engagement reliability without adding complex mechanical adjustment devices.
3Productivity
If manual connector engagement is used, then device simplicity is maintained, but operation complexity increases and productivity decreases
Solution Approach 1:
The driving unit automatically drives the second bracket to move horizontally, enabling the connector to autonomously engage with or disengage from the battery terminal connector. This self-service mechanism eliminates the need for manual intervention, improving both operational speed and simplicity simultaneously.
Solution Approach 2:
The manual mechanical engagement operation is replaced by an automated driving unit that provides horizontal movement force. This substitution of manual mechanical operation with an automated actuation system increases charging operation speed while maintaining ease of operation through automatic execution.
4Adaptability or versatility
If rigid connector connection is used, then manufacturing precision is easier to achieve, but adaptability to positioning variations is poor
Solution Approach 1:
The rigid fixed-position connector is replaced by a dynamic connector mounted on the movable second bracket. This dynamic structure inherently adapts to positioning variations through its movement capability, eliminating the need for extremely high manufacturing precision while maintaining reliable connection.
Solution Approach 2:
The horizontal position parameter of the connector is made variable through the movable second bracket. This parameter change capability allows the connector to adapt to different positioning scenarios, reducing the stringency of manufacturing precision requirements while improving positioning adaptability.
