Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional automotive electrical connectors are used with random positioning, then the connector assembly is simple in structure, but robotic manipulators cannot accurately grip and position the connectors
Solution Approach 1:
The alignment feature is segmented into multiple components: a slot in the connector assembly and a corresponding ridge on the robotic manipulator. This segmentation allows the robotic manipulator to grip and position the connector with high precision while keeping the overall structure relatively simple. The slot and ridge work together as separate but complementary elements to achieve accurate alignment.
2Measurement precision
If fixed alignment features such as pins or grooves are used to ensure proper alignment, then positioning precision is improved, but the flexibility and adaptability of the connector assembly to different robotic manipulators is limited
Solution Approach 1:
The slot and ridge alignment feature is designed to be universal, allowing it to work with different types of robotic manipulators. The slot can accommodate various ridge configurations, and the basic alignment principle remains the same across different manipulator designs. This universality enables the connector assembly to adapt to different robotic systems while maintaining precise alignment.
3Stability of the object's composition
If mechanical fasteners or clamps are used to secure the connector assembly to the robotic manipulator, then connection stability is improved, but the assembly process complexity and overall size increase
Solution Approach 1:
The invention extracts the essential alignment function from complex mechanical fastening systems. Instead of using multiple fasteners, clamps, or complex securing mechanisms, the solution uses a simple slot-ridge interface that provides both alignment and stable connection. This extraction of the core alignment function eliminates the need for additional fastening components and simplifies the assembly process.
4Ease of operation
If magnetic alignment systems are used to facilitate connection, then ease of operation is improved, but precision and rigidity are reduced
Solution Approach 1:
The invention merges the advantages of mechanical alignment (precision and rigidity) with the simplicity of magnetic alignment (ease of operation). The slot and ridge feature provides precise mechanical alignment when engaged, while the design allows for easy approach and engagement. The combination achieves both precision and ease of operation without relying solely on magnetic forces.
