Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If triplate lines are combined to form the antenna device, then the antenna structure is achieved, but the number of parts and screw fixing positions increases
Solution Approach 1:
The patent merges multiple triplate line components into a single integrated antenna assembly. The ground conductors of different triplate lines are coupled together to form a unified ground structure, and spacers are strategically positioned to maintain constant distances between ground conductors while reducing the total number of discrete parts. This integration maintains the functional antenna structure while simplifying the overall component count.
2Stability of the object's composition
If multiple spacers are used to maintain constant distance between ground conductors, then the structural integrity is ensured, but the assembly time increases
Solution Approach 1:
The spacers are pre-positioned at specific locations on the ground conductors during the design and manufacturing phase. This preliminary arrangement ensures that when the antenna device is assembled, the constant distance between ground conductors is automatically maintained without requiring complex real-time adjustments or additional assembly steps. The spacers are strategically placed to provide both structural support and precise spacing in a single assembly operation.
3Reliability
If ground conductors are coupled by bolts, then the electrical connection is achieved, but the manufacturing cost increases
Solution Approach 1:
The ground conductors are designed to be coupled directly or through integrated connectors rather than requiring separate bolt fastening mechanisms. This merging of the ground conductor structures allows for simpler joining methods that maintain electrical connectivity while reducing the need for additional fasteners, washers, and associated assembly operations, thereby lowering manufacturing costs.
