Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional antennas in wearable smart products are prone to breaking or falling off when curved or bent, leading to signal disruptions due to their rigid structure, which is not suitable for flexible electronic devices.
Innovation Solution
An antenna structure with a first base substrate, a second base substrate, a dielectric layer, and buffer blocks between the electrodes and the substrates, allowing the electrodes to curve without breaking and maintaining precise positioning, thus enhancing flexibility and signal accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional rigid antenna structures are used in wearable devices, then signal transmission can be maintained, but the antenna is prone to breaking or falling off when curved or bent
Solution Approach 1:
The patent applies flexible substrate materials (such as flexible printed circuit boards or thin flexible laminates) to replace rigid antenna structures. This allows the antenna to bend and curve without breaking, maintaining both signal integrity and flexibility for wearable applications. The flexible substrate enables the antenna to conform to curved surfaces while preserving electrical connectivity.
2Strength
If buffer blocks are added between electrodes and substrates to prevent breaking, then flexibility and bonding strength are improved, but device complexity increases
Solution Approach 1:
The patent integrates the buffer block functionality directly into the substrate structure or electrode mounting layer, combining multiple functions (mechanical support, stress distribution, and electrical connection) into a single integrated component. This reduces the number of separate parts and assembly steps, thereby decreasing device complexity while maintaining the bonding strength and flexibility benefits.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The antenna structure prevents electrode detachment and maintains signal integrity even when curved or bent, making it suitable for flexible electronic devices like wearable smart products by increasing bonding forces and buffering external forces.
Implementation Method 1

AI summary
An antenna structure and a communication device are provided. The antenna structure includes a first base substrate (110), a second base substrate (120), a dielectric layer (130) disposed between the first base substrate (110) and the second base substrate (120), and a plurality of first electrodes (115) disposed on a side of the first base substrate (110) close to the dielectric layer (130) and being spaced apart from one another. The antenna structure further includes at least one first buffer block (117) disposed between the first electrodes (115) and the first base substrate (110), the first buffer block (117) is at least partially and directly contacted with the first electrodes (115). Therefore, the antenna structure can be suitable for a flexible electronic device such as a wearable smart device.
