Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional electric power access system is used, then the structure is simple and easy to manufacture, but the system is not waterproof and cannot be used in humid environments
Solution Approach 1:
The power supply track is divided into multiple slots, each containing a conductive member and sealed with an independent strip seal. This segmentation allows each slot to be sealed independently while maintaining the overall waterproof structure, enabling the system to function in humid environments without excessive complexity.
Solution Approach 2:
The strip-shaped conductive members are nested within the slots, and the strip seals are positioned to seal the slots while allowing the conductive members to remain accessible for electrical connection. This nested arrangement protects the conductive members from moisture while maintaining electrical functionality.
2Reliability
If the current collector members directly contact the conductive members without protection, then the electrical connection is simple, but the waterproof structure is damaged
Solution Approach 1:
The strip seals act as intermediaries between the waterproof structure and the electrical connection components. These seals are designed to be elastically deformable, allowing current collector members to pass through or contact them while maintaining the waterproof barrier, thus protecting the waterproof structure while enabling electrical connection.
Solution Approach 2:
The strip seals are designed with specific elastic properties that allow them to deform temporarily during the electrical connection process and then return to their original state. This parameter change (elastic deformation) enables the seals to accommodate the insertion of current collector members while maintaining waterproof integrity after connection.
3Reliability
If the strip seals are made highly durable and resistant, then the waterproof performance is improved, but the damage during electrical connection increases
Solution Approach 1:
The strip seals are designed with optimized elastic parameters that allow them to be sufficiently durable for waterproof performance while being soft enough to minimize damage during the electrical connection process. The material properties are carefully selected to balance durability and deformability.
Solution Approach 2:
The strip seals are pre-installed in the slots with appropriate pre-compression and positioning to cushion the impact and stress during the electrical connection process. This beforehand cushioning protects both the waterproof structure and the seals from excessive damage while maintaining their sealing function.
