Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed receiving antenna is used, then the structure is simple and easy to manufacture, but the receiving direction cannot be adjusted effectively
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed antenna structure into a foldable dynamic structure. The antenna panel is divided into multiple folding units connected by folding creases, allowing the antenna to change its shape and receiving direction by folding and unfolding. This enables the antenna to adapt to different receiving directions while maintaining a relatively simple overall structure without complex adjustment mechanisms.
2Reliability
If a high-gain antenna is used, then the receiving performance is improved, but the size becomes large and packaging costs increase
Solution Approach 1:
The patent applies segmentation by dividing the antenna panel into multiple folding units (first folding unit, second folding unit, etc.) connected by folding creases. This segmentation allows the antenna to be folded into a compact form for reduced packaging volume and transportation costs, while still maintaining the necessary surface area for high-gain signal reception when deployed.
Solution Approach 2:
The patent implements the nested doll principle by enabling the antenna to fold into a compact nested configuration. When not in use or during transportation, the multiple folding units can be folded inward and nested within each other, significantly reducing the occupied space while preserving the full antenna surface area for signal reception when unfolded.
3Stability of the object's composition
If a thick antenna is mounted on an ultra-thin TV, then the structural stability is improved, but the aesthetic appearance deteriorates
Solution Approach 1:
The patent applies flexible shells and thin films by using a thin-panel design with multiple folding units that can be connected through flexible folding creases. This allows the antenna to maintain a thin profile suitable for ultra-thin TVs while providing sufficient structural stability through the distributed folding unit structure and support mechanisms within each unit.
4Ease of manufacture
If the antenna layer is directly connected without protection, then the manufacturing process is simple, but the antenna layer is prone to scratching and conductivity decreases
Solution Approach 1:
The patent applies flexible shells and thin films by introducing a protective flexible layer that covers the antenna layer. This flexible protective layer prevents scratching and damage to the antenna layer during folding and transportation, while maintaining the electrical conductivity of the antenna system and not significantly complicating the manufacturing process.

AI summary
A foldable receiving antenna has an antenna body which is divided into a plurality of folding units by at least one folding crease, wherein the antenna body has a plurality of layers, including a connecting layer spanning the folding crease for connecting adjacent two folding units, a centrally located support layer, a cover layer centrally symmetrically arranged at the both sides of the support layer, and an antenna layer disposed between the support layer and the cover layer. The foldable receiving antenna is free from large size and expensive pack and transport cost, inconvenient receiving direction of the antenna, and aesthetically unpleasing caused by thick thickness of the antenna mounted on an ultra-thin TV.
