Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If various frames are coupled between the motor and the main frame to support the motor, then the motor support structure is stable, but the structure becomes complex
Solution Approach 1:
The support frame integrates multiple support functions into a single unified structure. The support frame includes a first support portion for supporting the battery and a second support portion for supporting the motor, eliminating the need for separate support structures for each component. This merging of functions reduces structural complexity while maintaining stability.
Solution Approach 2:
The support frame serves multiple purposes: it supports the battery, supports the motor, and provides structural connection between components. By designing the support frame with multi-functional capabilities, the patent reduces the number of separate structural elements needed, thereby simplifying the overall motor support structure while ensuring stability.
2Ease of manufacture
If the support frame structure is simplified, then manufacturing is easier, but maintenance accessibility may be reduced
Solution Approach 1:
The support frame is divided into distinct functional portions: a first support portion for the battery, a second support portion for the motor, and coupling portions for connecting to the main frame. This segmentation allows for simplified manufacturing of each portion while maintaining overall structural integrity and providing accessible interfaces for maintenance operations.
Solution Approach 2:
The support frame acts as an intermediary structure between the main frame and the motor/battery components. It provides standardized coupling portions that facilitate easy assembly and disassembly, making maintenance accessible while keeping the overall structure simple and manufacturable.
3Object-generated harmful factors
If the coupling portion protrudes downward from the support frame, then the coupler does not interfere with the battery, but the structure requires additional design complexity
Solution Approach 1:
The coupling portion is designed to protrude downward from the support frame in the vertical dimension, while the battery is positioned above the support frame. This spatial arrangement in different vertical positions eliminates interference between the coupler and battery without requiring complex lateral positioning mechanisms.
Solution Approach 2:
Instead of having the coupling portion extend upward or laterally where it might interfere with the battery, the design inverts the direction by having the coupling portion protrude downward. This inversion of the coupling direction naturally avoids interference with overhead components like the battery.
