Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a traditional dipole antenna is made with two coplanar metal planes and a cable, then the antenna structure is simple and easy to manufacture, but the area occupied is larger than other components and metal interference reduces operational efficiency
Solution Approach 1:
The patent introduces an insulator as an intermediary component between the inner conductor and outer conductor of the cable. This insulator prevents direct contact between the conductors and reduces metal interference effects, thereby improving operational efficiency while maintaining the simple coplanar structure of the dipole antenna
Solution Approach 2:
The patent employs composite material structure by combining metal planes for radiation, insulating materials for isolation, and conductive materials for signal transmission. This composite approach allows the antenna to maintain structural simplicity while reducing metal interference through the insulating layer, thus improving operational efficiency
2Adaptability or versatility
If metal housing and complex internal circuits are added to meet functional and appearance demands, then the device functionality and appearance quality are improved, but metal interference with the dipole antenna increases
Solution Approach 1:
The insulator serves as a mediator that isolates the dipole antenna from interfering metal structures in the housing and internal circuits. By placing this insulating layer between the antenna conductors and surrounding metal components, the patent reduces electromagnetic interference while allowing the device to incorporate complex internal circuits and metal housing for enhanced functionality
3Area of stationary object
If the dipole antenna area is reduced to save space, then the space occupancy is reduced, but the operational efficiency is obviously decreased due to metal interference
Solution Approach 1:
The insulator acts as a protective intermediary that enables the dipole antenna to operate efficiently even in a reduced area. By preventing direct contact between metal components and isolating the conductors, the insulator reduces interference effects that would otherwise be magnified in a compact configuration, thus maintaining operational efficiency despite smaller antenna dimensions
