Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If traditional rigid flat panel antennas are used, then antenna radiation performance is maintained, but packaging volume and transportation cost increase significantly
Solution Approach 1:
The antenna transitions from a static rigid flat panel structure to a dynamic flexible structure that can change its physical form between unrolled (operational) and rolled (transportation) states. This dynamic transformation allows the antenna to adapt to different requirements: maintaining flat radiation performance during use while achieving compact cylindrical packaging during logistics, thereby reducing packaging volume while ensuring transportation reliability.
Solution Approach 2:
The antenna's physical parameters are changed by transitioning between two states: in the unrolled state, it maintains its flat panel geometry for optimal radiation; in the rolled state, it transforms into a compact cylinder for space-efficient packaging. This parameter change enables the antenna to simultaneously achieve small packaging volume and reliable protection during transportation.
2Ease of manufacture
If rigid materials are used for flat panel antennas, then structural stability is maintained, but transportation cost and packaging material consumption increase
Solution Approach 1:
The patent replaces traditional rigid materials with flexible substrate materials that can be rolled and unrolled. This flexible shell approach allows the antenna to be packaged in a compact cylindrical form, dramatically reducing packaging structure volume while maintaining manufacturing simplicity through flexible substrate fabrication techniques.
3Reliability
If large-sized packaging structure is used, then antenna protection during transportation is improved, but transportation efficiency decreases and cost increases
Solution Approach 1:
The antenna's ability to dynamically transform between unrolled and rolled states enables compact packaging that improves transportation efficiency. The rolled cylindrical form factor significantly reduces packaging volume compared to traditional rigid antenna packaging, allowing more units per shipment while maintaining protection through the compact, space-efficient cylindrical structure.

AI summary
An antenna packaging structure includes a packaging container and an antenna contained in the packaging container. The antenna includes a flexible substrate, an antenna element disposed on the flexible substrate, a feeder structure connected to the antenna element, and a coaxial cable connected to the feeder structure. The flexible substrate of the antenna is rolled into a cylindrical structure, with the antenna element rolled together with the flexible substrate and retained electrical properties after unrolled, the feeder structure is disposed inside or to a side of the cylinder structure, and the coaxial cable is disposed inside the cylinder structure or between the cylinder structure and the packaging container. The present disclosure can effectively ensure safety and stability of the antenna during transportation and storage, reduce risk of damage due to external forces or environmental factors, provide compressed space occupied, and correspondingly improve efficiency of transportation and storage.
